SYSTEM FOR PRESERVING AND DETERMINING INGREDIENTS AND METHOD OF STORING AND DOSING USING SUCH A SYSTEM
Technical area
The present invention relates to a system for preserving and dosing ingredients, and a method for assaying ingredients stored in such a system.
The present invention is in the field of the preservation of foodstuffs used in artisanal or semi-industrial processes, and more particularly the field of automated preparation of culinary preparations from these foodstuffs.
State of the art
In a known manner, storage chambers are known which make it possible to preserve foodstuffs for long periods thanks to lowered storage temperatures in order to slow or even prevent the microbial and bacterial growth of the foodstuffs stored therein. It may be for example refrigerators, cold rooms or freezers depending on the chosen storage temperatures. The ingredients are deposited in the storage chamber, possibly inside compartments to optimize their storage.
There are also known automatic machines manufacturing culinary preparations - for example pizzas - and implementing storage tanks coupled to sampling devices in order to collect a predetermined amount of a portion of the ingredients stored in the storage tanks. Each storage tank is then equipped with a motorized opening and closing mechanism to allow the extraction of the expected quantity of ingredients. The disadvantage of the systems implemented in such machines is the limitation of the number of different recipes that can generally be obtained. Indeed, a compromise must generally be made between the number of storage tanks and the diversity of possible recipes. According to a first variant, each tank may contain all the ingredients necessary for making a given pizza recipe, that is to say pizzas made from given types of ingredients. A lowered pizza dough can then be placed under the tank of the selected recipe, in order to simultaneously receive all the ingredients of this recipe. The number of storage tanks required is then at least equal to the number of recipes that one wishes to obtain.
According to a second variant, each tank contains a limited number of ingredient types, or even a single type of ingredient. The preparation of varied recipes then involves having as many tanks as the types of ingredients making up the different recipes. A disadvantage of this second variant is that the lowered pizza dough must then be moved under each tank containing one of the ingredients of the selected recipe. These successive displacements involve the presence of a complex and cumbersome handling system. In practice, the size of the storage tanks and the handling system involves limiting the number of tanks, to limit the size of the cold room, and therefore its manufacturing cost and energy consumption during use. Furthermore, the movement of the pizza dough between the different tanks causes a relatively long ingredient depositing time with respect to the first variant. The overall duration of making a pizza is extended.
Finally, for a given reservoir, the deposition on the surface of the reduced pizza dough of the predetermined quantity of ingredients is generally carried out by a complex system of relative displacement of said reservoir relative to the lowered pizza dough: either the lowered pizza dough that is placed on a moving cart that moves under the tank spilling the ingredients, or it is the tank that moves over the lowered pizza dough. The disadvantage of this deposition system is that it is complex to implement and also consumes energy to ensure the relative movement of the pizza with respect to the tank from which the ingredients are poured. Moreover, for a given relative relative displacement, the deposit of said ingredients will be reproducible and such systems are not therefore compatible with the automated making of semi-traditional pizzas for which the ingredients are not posed in a fully reproducible way of a pizza to the other.
The object of the present invention is to respond at least in part to the above problems and to furthermore provide other advantages.
Another object of the invention is to solve at least one of these problems by a new system for preserving and dosing ingredients.
Another object of the present invention is to facilitate the management of a freezer and in particular the supply and preservation of foodstuffs.
Another object of the present invention is to automate the extraction of preserved foods.
Another object of the present invention is to reduce energy consumption and the dimensions of a storage chamber.
Another object of the present invention is to be able to precisely select the type and quantities of food extracted.
Another goal is to accelerate and simplify the deposition of food on a substrate.
Another object of the present invention is to be able to deposit foodstuffs in a homogeneous and random manner on a substrate during a single operation.
Presentation of the invention
According to a first aspect of the invention, at least one of the abovementioned objectives is achieved with a system for preserving and dosing ingredients, comprising: a storage chamber comprising a set of compartments arranged for storing ingredients; device for sampling and dosing ingredients, arranged to be able to take or extract successively in each of the compartments a predetermined quantity of ingredients, said device for sampling and dosing ingredients comprising: - a recovery tank arranged to store temporarily and in successive layers the ingredients taken from each compartment, - a controlled conveying mechanism, arranged to be able to move the recovery tank directly above each compartment so that the ingredients taken from said compartment fall into the recovery tank, - a control unit, programmed to control the conveyor mechanism and the sampling and dosing device.
The preservation chamber may include refrigeration means for maintaining a temperature within the chamber below 15 ° C or maintaining dry storage conditions. Preferably, the refrigeration means make it possible to maintain a temperature inside the chamber lower than 4 ° C. in order to slow down or stop the bacterial growths and to slow the undesirable chemical reactions on the preserved ingredients.
According to a preferred embodiment, the storage chamber comprises freezing means arranged to maintain it at a temperature below 0 ° C, and preferably at a temperature between -18 ° C and -30 ° C.
The preservation chamber implemented in the first aspect of the invention comprises a plurality of compartments in which the ingredients are preserved. The compartments are arranged inside the storage chamber so that the sampling device can be positioned near each compartment to take a predetermined amount.
In general, each compartment can take the form of a cylindrical receptacle whose dimensions are adapted to the preservation of ingredients preferentially cut into pieces and "ready for use" in a culinary preparation. By way of non-limiting example, the volume of each compartment may be between 0.5 liters and 100 liters.
According to the prepared culinary preparations, the preserved ingredients can be of any type: pre-cut fish, fruits and / or vegetables, meats, cereals, pre-cut and / or grated cheeses, confectionery, pieces of sauces and, in general , all types of food products used in the preparation of culinary preparations (flours, fruits and vegetables, whether or not processed, pieces of chocolate, sugar, caramel ...)
Each compartment may include a closure means - at least partially - arranged to allow in a first configuration to retain all the ingredients contained in said compartment and, in a second configuration, to allow the removal of at least a portion of the ingredients contained in said compartment by the sampling and dosing device. By way of non-limiting example, the closure means may consist of a removable hatch disposed at a lower end of the compartment. The closure means may also comprise two pivoting flaps opening opposite each other, or a diaphragm. According to a particular embodiment, the sealing means is part of the sampling and dosing device. The sampling and dosing device comprises for example a mechanism of the worm type. This mechanism can then fulfill the shutter function, in particular when the opening of the compartment is located at one end of an axis of revolution of the screw.
Preferably, each compartment is filled with a single type of ingredient in order to manage their supply easier and more accurate according to their sampling and consumption and thus offer personalized dishes. In this case, the storage chamber may include a large number of compartments arranged in the storage chamber. It is thus easier to anticipate the replenishment of the ingredients. In addition, if some of the ingredients stored in the storage room are contaminated or unfit for consumption, it is then possible to dispose of them and replace them while keeping the other ingredients that are not contaminated and / or unsuitable. for consumption. In a more general manner, the preservation chamber implemented in the first aspect of the invention allows better sanitary management of the preserved ingredients.
Optionally, according to a particular embodiment, each compartment can be sealed to further reduce the risk of contamination between compartments. By way of nonlimiting example, the storage chamber implemented in the first aspect of the invention may comprise between 2 and 200 compartments.
Advantageously, the space in front of each compartment is sufficient to allow the displacement of the sampling device.
Possibly the storage chamber comprises a door allowing easy access and simultaneous access to all compartments to facilitate filling and / or maintenance operations, and secondly the hermetic closure of said storage chamber to limit thermal losses.
Optionally, the storage chamber also comprises a plurality of filling doors located on the outer side walls, each of the filling doors for filling and / or clean one or more juxtaposed compartments without opening the possible door of the storage chamber. Incidentally, a filling duct may connect each compartment to the filler door with which it is associated, depending on the thickness of the side wall of the storage chamber and / or the position of said compartment in the storage chamber. It is thus possible to achieve the supply of ingredients while limiting heat losses, energy consumption and the costs of use of the storage chamber. In general, the compartments are preferably arranged inside the storage chamber so that the sampling device can move in at least one direction to collaborate with each compartment and take the predetermined quantity of ingredients. .
According to an advantageous embodiment, the sampling device is arranged to move in two perpendicular directions in the storage chamber, or in three perpendicular directions.
According to the first aspect of the invention, the device for sampling and dosing the ingredients is able to move successively in line with or near each compartment. The displacement is provided by a conveying mechanism arranged to ensure a displacement along one, two or three axes, successively or simultaneously, inside the storage chamber, according to the organization of the compartments inside thereof .
The conveying mechanism may comprise a one, two or three axis guidance system for guiding the sampling and dosing device to any of the compartments in the storage chamber. An actuator placed on each of the axes of movement makes it possible to independently control the movement of the device along each axis. The control unit is programmed to control in particular at least one actuator of the conveying mechanism.
For a movement of the sampling device along a single axis inside the storage chamber, the conveying mechanism may comprise, for example, a first, so-called primary, guide rail, preferably oriented in the direction of the largest inner dimension of the the preservation chamber and for example fixed integrally on a wall of the storage chamber. A motorized moving element, said primary, is mounted in sliding connection with the primary guide rail.
In this configuration, all of the compartments are preferably aligned in a single direction parallel to the direction of the first guide rail within the storage chamber, so that the ingredient picking device can stop nearby. from each compartment to take a predetermined amount of ingredients.
For displacement of the sampling device along two axes inside the storage chamber, the first primary guide rail may be associated with a second primary guide rail, preferably disposed on the face opposite to that on which the first rail primary guide is fixed and oriented in a direction parallel to that of the first primary guide rail. The second primary guide rail then comprises a second primary movable element, in sliding connection with said second primary guide rail. Optionally, the second primary mobile element can be motorized.
The two primary movable elements are then interconnected by another, so-called secondary, guide rail oriented substantially in a direction perpendicular to that of the primary guide rails. Thus, when the at least one motorized primary movable element is actuated, it drives in translation the secondary rail in the direction of the primary guide rails. A motorized moving element, said secondary, is mounted in sliding connection on the secondary guide rail in order to carry out the translation.
In this configuration, all compartments are preferably arranged in a plurality of rows and columns on one or more inner faces of the storage chamber, so that the device for sampling ingredients can stop near each compartment to take a predetermined amount of ingredients.
Finally, for a movement of the sampling device along three axes within the storage chamber, a tertiary guide rail in a direction perpendicular to the primary and secondary guide rails can be fixed on the secondary movable member. A tertiary motorized movable element is then mounted in sliding connection on the tertiary guide rail so as to generate a displacement in this direction.
In this configuration, the ingredient sampling device can thus move within the entire storage chamber, providing more possibilities for organizing the compartments within the storage chamber. In addition, the storage capacities are increased. By way of non-limiting example, in such a configuration, the storage chamber could accommodate compartments on at least two opposite faces, or even on all the inner walls of the storage chamber. Preferably, the compartments are organized along lines and columns so that the sampling device can stop near each compartment and take a predetermined quantity of ingredients. The control unit is programmed to control the movements of the at least one motorized moving element in order to position it in particular close to at least a part of the compartments in order to take a predetermined quantity of ingredients, the quantity of sampled ingredients may be different depending on the compartments.
For all the configurations mentioned above, the position of the moving elements along the corresponding guide rail and the position of each compartment can be determined by calibration. Optionally, the position of each movable element along each guide rail can be measured using sensors installed in the conservation chamber or encoders embedded on said movable elements.
The sampling device comprises a recovery tank capable of temporarily storing the ingredients taken from each selected compartment. Thus, when a sampling command is sent by the controller to said sampling device, for example according to a predetermined recipe, the conveying mechanism sequentially moves the collecting tank near each compartment comprising an ingredient of the order sampling and / or the predetermined recipe. The recovery tank can in particular be positioned vertically above each compartment or, more precisely, directly above the outlet orifice of each compartment. For each compartment, the sampling device performs a coupling between the recovery tank and the compartment to collect the predetermined amount of ingredients. The modalities of this coupling will be described later. When the sampling of the ingredients contained in a compartment is completed, the sampling device decouples the recovery tank of said compartment and moves to the next selected compartment. Thus, for a given sampling order and / or a given recipe, all the ingredients are taken during the same sampling cycle comprising a plurality of sampling steps.
Advantageously, the recovery tank also comprises a motorized emptying means arranged to take at least two configurations: a first so-called closed configuration for retaining all the ingredients contained in the recovery tank, and a so-called open configuration for emptying the recovery tank of all the ingredients. The motorized emptying means is preferably located on a lower face of the recovery tank so that the ingredients it contains are removed under the simple effect of gravity. By way of nonlimiting examples, the emptying means may comprise at least one motorized removable hatch, a motorized diaphragm, a spring or magnet mechanism with opening and / or closing by mechanical stop or any other equivalent mechanism.
It is thus possible to automate the collection of the ingredients stored in the storage room and to be able to precisely select the type and quantities of ingredients taken.
Preferably, the device for sampling and dosing ingredients of the preservation system according to the first aspect of the invention further comprises a device for measuring the weight and / or the volume of the ingredients being sampled, the unit control being programmed to stop the withdrawal of the ingredients of a compartment when the predetermined quantity of ingredients has been taken. As non-limiting examples, the device for measuring the weight of the ingredients being sampled may be a scale fixed under the recovery tank measuring the instantaneous weight of said recovery tank during the sampling operation (and filling of said recovery tank) . Typically, the weight sensor is arranged and configured to measure the weight of the recovery tank over a sampling period well below the sampling time. It is thus possible to determine the quantity of ingredients being extracted and to better determine the conditions for stopping said extraction of the ingredients.
Alternatively or additionally, a volume sensor may be implemented on the sampling and dosing device of the extracted ingredients in order to determine the volume of said extracted ingredients. Indeed, for certain particular culinary preparations, the proportions of necessary ingredients are defined in terms of volumes rather than weight.
According to a particular configuration, such a volume sensor may comprise for example a plurality of laser diodes arranged to define an optical comb according to a measurement plane substantially perpendicular to the direction of fall of the extracted ingredients. Each laser diode is also coupled to a photodetector disposed opposite so that when an ingredient is extracted from a compartment, it cuts the beam of at least one laser diode. In other words, the set of laser diodes and photodetectors is arranged to cover the entire drop surface of the ingredients taken from a compartment to the recovery tank.
Preferably, the drop of an extracted ingredient to the recovery tank cuts the beam of at least two laser diodes located at most 60 ° from each other.
The photodetectors are for example arranged and configured to record the light intensity emitted by the laser diodes located opposite at a sufficiently high sampling frequency to record at least ten intensity measurements per extracted ingredient. By way of non-limiting example, the sampling frequency is at least 10 kHz.
Thus, each photodetector makes it possible, by integration of measurements made for an extracted ingredient falling in the recovery tank, to calculate an infinitesimal volume of said ingredient calculated from the width of the optical beam and the measured duration between the crossing of the beam by one end. lower of the ingredient (corresponding to a sudden attenuation of the measured light intensity) and the crossing of the upper end of said ingredient (corresponding to a re-increase in the measured light intensity).
By combining laser diodes and photodetectors, it is thus possible to calculate the volume of each ingredient that has passed through the optical comb. By way of example, the calculation of an infinitesimal volume can be obtained from the dimensions of the photodetector and from the duration thus calculated with respect to the curves of variation of the luminous intensity. The total volume of an ingredient can be calculated by summing at least a portion of the infinitesimal volumes.
Advantageously, in the preservation system according to the first aspect of the invention or one of its improvements, the conveying mechanism is arranged to be able to move the recovery tank in an unloading configuration, in which the recovery tank is placed in line with the substrate, and the recovery tank is also arranged to be able to deposit on or in the substrate the ingredients taken from the compartments.
It is thus possible to prepare culinary preparations from a predefined recipe, and according to selected ingredients in amounts adapted to said recipe. To do this, the substrate of the food preparation is placed under the sampling and dosing device in the storage chamber, so that the ingredients contained in said sampling and dosing device are poured therein. The substrate can be edible.
The type of substrate varies according to the culinary preparation concerned. It may be for example a bread dough, a shortbread dough, a broken dough, a puff pastry or, in general, any paste suitable for serving as a support or binder for ingredients. The dough can be lowered, for example to make a pizza, or dark in a mold, for example to make a quiche.
The device according to the invention is also designed to prepare recipes of ingredients eaten raw, for example at breakfast, such as cereal mixtures, fruit salads. In some cases, the substrate may not be edible: it may be, for example, glasses, cups, bowls or plates.
Optionally, the different substrates - edible or inedible - are stored in the storage chamber and transferred on demand below the sampling and dosing device to deposit the ingredients taken from and contained in said sampling device and dosing by a conveying mechanism.
Alternatively, the substrates are imported "on demand" into the storage chamber by a conveying mechanism below the sampling and dosing device in order to deposit the ingredients taken from and contained in said sampling and dosing device. Optionally, a motorized access hatch of the storage chamber makes it possible to carry out this transfer and to introduce the substrate into the storage chamber or to extract the substrate from the storage chamber. In its open configuration, it allows the substrate to be transferred under the sampling and dosing device to receive the selected ingredients. In its closed configuration, the access door guarantees a tight closure of the storage chamber in order to limit energy losses.
When the sampling and dosing device has taken the ingredients in all the compartments selected for the production of said recipe in predetermined quantities, the controlled conveying mechanism moves the sampling and dosing device in such a way as to vertically align the recovery tank and the tank. substrate on which the ingredients are deposited.
More generally, the sampling device is positioned above the substrate in such a way that the ingredients fall under the effect of the gravity of the recovery tank on the substrate.
As mentioned above, the sampling and dosing device collaborates with each compartment to take a predetermined quantity of ingredients. This collaboration can be carried out according to three embodiments which will now be described in more detail.
According to a first embodiment of the invention according to any one of the improvements, each compartment may comprise: an extraction element arranged to be able to take a part of the ingredients contained in said compartment; a motor unit arranged to be able to actuate the extraction element, in particular when it collaborates with said sampling and dosing device; the sampling and dosing device being configured to be able to take at least two configurations: a so-called coupled configuration, in which the recovery tank is placed in line with one of the compartments in order to collaborate with said compartment and to be able to recover extracted ingredients; a so-called uncoupled configuration in which the sampling and dosing device is able to move to another compartment and / or to the unloading configuration.
According to this first embodiment, each compartment comprises the elements that allow the controlled extraction of the ingredients they contain. This is on the one hand the extraction element and the motor member that controls the extraction element.
In general, the extraction element can take at least the following two configurations. - A first so-called passante configuration for extracting in a controlled manner a portion of the ingredients contained in the corresponding compartment. Depending on the type of extraction element, the passing configuration may be static or dynamic, depending on whether the extraction element is respectively immobile or moving. By way of nonlimiting examples, in the case where the extraction element comprises a screw of which a first part is inside the compartment and a second part is outside, the passing configuration is dynamic by the setting in rotation of the screw: at each turn of screw, a given amount of ingredients is conveyed from inside the compartment to the outside. Alternatively, a passing configuration is static if the extraction element takes a position - still - in which part of the ingredients contained in the compartment can be extracted without requiring movement of the extraction element. By way of non-limiting example, it may be a hatch located on the lower part of the compartment. When the hatch is in open configuration, the ingredients contained in the compartment can fall out of the compartment under the simple effect of gravity. By adjusting the opening of the hatch, the extraction speed of the ingredients can be controlled. - A second so-called closed configuration to retain all the ingredients in the compartment. The drive member is arranged to actuate the extraction element, on the one hand to move it from one configuration to another, and possibly to operate the extraction element in the dynamic pass-through configuration. It may be for example a stepper motor arranged to rotate a shaft that rotates a screw or rotates a hatch.
In this first embodiment, the sampling and dosing device is arranged to collaborate with each compartment, preferably one after the other. In general, the sampling and dosing device can take two alternative configurations. - A first so-called coupled configuration, wherein the sampling and dosing device is located near a compartment to allow the extraction of a portion of the contained ingredients and recover them in the recovery tank. In this coupled configuration, the extraction element can be switched from the closed configuration to the pass-through configuration to extract a predetermined amount of ingredients out of the compartment. When the predetermined amount is reached, the extraction element is re-shifted into the closed configuration. Optionally, in this configuration, the sampling and dosing device establishes a temporary and reversible connection with the compartment in order to perform a mechanical coupling and to keep the relative position of the sampling device with respect to said compartment during the extraction of the ingredients. A second so-called decoupled configuration, in which the sampling device is free to move from one compartment to another, or possibly in another configuration.
According to a second embodiment according to any one of the improvements of the first aspect of the invention, the sampling and dosing device may comprise: an extraction element arranged to be able to collaborate successively with each compartment so as to extract a part of the ingredients contained by the compartment with which the extraction element collaborates; a drive member arranged to be able to actuate the extraction element when it collaborates with one of said compartments; said sampling and dosing device being configured so as to be able to take at least two configurations: a so-called coupled configuration in which the extraction element is coupled to one of the compartments in order to extract some of the ingredients towards the tank; recuperator; a so-called decoupled configuration in which the extraction element is decoupled from each compartment so as to allow the sampling and dosing device to be able to move to another compartment and / or to the unloading configuration.
According to this second embodiment, the extraction element and the motor member are no longer integrated on each compartment but are both implemented on the sampling and dosing device in order to - jointly - extract in a controlled manner the ingredients contained in the compartments.
Optionally, each compartment may further comprise a closure means arranged to prevent the ingredients contained in said compartment from falling out of the compartment when the latter does not cooperate with the sampling and dosing device. It may be for example a passive element, such as a valve, or dynamic as a motorized hatch.
In a manner comparable to the first embodiment, the extraction element located on the sampling and dosing device can alternatively take at least one pass-through configuration - static or dynamic - and a closed configuration.
In a manner comparable to the first embodiment, the sampling and dosing device is arranged to collaborate with each compartment, preferably one after the other and through two alternative configurations. A first so-called coupled configuration, in which the sampling and dosing device establishes a temporary and reversible connection with the compartment with which it collaborates. In this coupled configuration, the extraction element can be switched from the closed configuration to the pass-through configuration to extract a predetermined amount of ingredients out of the compartment. When the predetermined amount is reached, the extraction element is re-shifted into the closed configuration. A second so-called decoupled configuration for which there is no longer any coupling between the sampling and dosing device and the compartment, possibly enabling the sampling and dosing device to move from one compartment to the other.
This embodiment makes it possible cleverly to limit the number of movable elements and / or motors necessary for the extraction of the ingredients contained in the compartments. It also makes it possible to save the manufacturing cost of the preservation and dosing system according to the invention.
According to a third embodiment of the invention according to any one of its improvements: each compartment comprises an extraction element arranged to be able to collaborate with the sampling and dosing device and to take part of the ingredients contained in said compartment; - The sampling and dosing device comprises a motor unit arranged to be able to collaborate successively with each compartment so as to operate the extraction element of the compartment with which it collaborates; said sampling and dosing device being configured so as to be able to take at least two configurations: a so-called coupled configuration, in which the motor unit is coupled to the extraction element of one of the compartments so as to be able to actuate the extraction element of said compartment and take a portion of the ingredients of said compartment to the recovery tank; a so-called decoupled configuration in which the motor unit is decoupled from each extraction element, so as to allow the sampling and dosing device to move to another compartment and / or to the unloading configuration.
This third embodiment constitutes an intermediate configuration to the two embodiments described above. Indeed, in this embodiment, an extraction element is implemented on each compartment while the motor unit is implemented in a pooled manner on the sampling and dosing device.
In a manner comparable to the first and second embodiments, the extraction elements located on each compartment can alternatively take at least one pass-through configuration - static or dynamic - and a closed configuration.
In a manner comparable to the first and second embodiments, the sampling and dosing device is arranged to collaborate with each compartment, preferably one after the other and through two alternative configurations. - A first so-called coupled configuration, wherein the sampling and dosing device establishes a temporary and reversible connection between the motor member located on said sampling and dosing device and the extraction element located on each compartment. Once the coupling is completed, the extraction element can be switched from the closed configuration to the pass-through configuration in order to extract a predetermined quantity of ingredients from the compartment. When the predetermined amount is reached, the extraction element is re-shifted into the closed configuration. A second so-called decoupled configuration for which there is no longer any coupling between the drive member of the sampling and dosing device and the extraction element of the compartment, possibly enabling the sampling and dosing device to move from one compartment to another.
This embodiment makes it possible to simplify the design of the compartments and the operation of the storage and dosing system according to the invention. Indeed, the preservation of the ingredients inside each compartment can be entirely ensured by the extraction element, integral with said compartments, and which is tilted in its passing configuration only during coupling with the motor member of the device. sampling, said extraction element can return to its closed configuration once the drive member decoupled. It is also possible to select and extract ingredients out of the storage chamber more quickly, making it possible to make recipes from said ingredients more quickly.
Optionally, the extraction element of the conservation system according to the first aspect of the invention or one of its improvements may comprise a mechanism of the worm type, the mechanism comprising a screw whose geometry - including the step screw - and rotational speed control the amount and rate of extraction of the ingredients.
This extraction element makes it possible to very simply obtain both the passing configuration by rotating the screw and the closed configuration holding said screw in a given position. In fact, in the case of non-liquid ingredients contained in the compartment, the stationary position of the screw makes it possible to retain the ingredients and to prevent them from falling under the simple effect of gravity outside the compartment.
Optionally, the axis of rotation of the screw is inclined towards a rear face of the compartment so that, when the screw is rotated to extract the ingredients contained in said compartment (sampling configuration), these are conveyed by the screw from a position located below in the compartment to an elevated position before being expelled out of said compartment. This arrangement of the axis of rotation of the screw inside the compartment allows better retention of the ingredients when said screw is at rest (storage configuration).
Preferably, each compartment comprises an inner tube wrapping the front portion of the screw located inside the compartment.
This inner tube thus forms a way for the passage of the ingredients conveyed by the screw towards the outside of the compartment.
Each compartment may include, in place of or in addition to the inner tube, a partial closure member located at an outlet port of the compartment. This closure element may have an opening diameter smaller than the diameter of the screw. It is then made of a flexible material, so as to be deformed during the rotation of the screw. The closure member comprises for example a set of tabs extending concentrically from the periphery of the outlet port. The partial closure element makes it possible to limit the volume of ingredients conveyed by the screw. According to a second aspect of the invention, there is provided a distribution device, adapted to be located in an intermediate position between an ingredient tank located above said distribution device and a substrate on which the ingredients must be poured, and arranged to allow a homogeneous and random distribution on said substrate of ingredients passing through the distribution device.
Preferably, the ingredients extracted from the tank fall through the distribution device under the simple effect of gravity, for example by opening a hatch located on the lower part of said tank. In a schematic manner, the ingredients extracted from the tank fall -preferentially in free fall-through the distribution device. The ingredients extracted from the reservoir arrive with a non-zero kinetic energy and whose velocity vectors are mainly oriented in a vertical direction, the transverse components being zero or much lower than the vertical components.
The distribution device is arranged to modify the trajectory of the ingredients passing through it, so that they acquire a non-zero speed in at least one direction substantially transverse to the direction of the fall of said ingredients, thus leading to dispersing transversely and randomly the ingredients. passing through said distribution device.
Advantageously, the distribution device laterally disperses the ingredients passing through it completely passively, that is to say without implementing motorized elements.
Additionally, the dispensing device can disperse the ingredients in a plurality of directions transverse to the falling of said ingredients without adding additional energy to the mechanical energy accumulated by said falling ingredients.
More particularly, the ingredient distribution device may comprise a mixing cylinder placed above the substrate - for example a lowered dough, a longitudinal axis of the mixing cylinder being perpendicular to the surface of the substrate, the mixing cylinder comprising , between an upper end and a lower end, obstacles arranged to oppose the free fall of the ingredients, so as to generate a random lateral displacement of the ingredients to distribute them randomly and homogeneously to the surface of the substrate.
The lateral dimensions of the distribution device are adapted to the lateral dimensions of the substrate on which the ingredients are deposited, so that all the ingredients passing through the distribution device finally fall on the substrate. More particularly, the outer dimensions of the mixing cylinder are smaller than the outer lateral dimensions of the substrate on which the ingredients are deposited. By way of example, in the case where the substrate is a lowered dough for the preparation of a pizza, the mixing cylinder may advantageously take the form of a cylinder of revolution whose guide curve is a circle, the diameter of said circle being slightly less than the diameter of the reduced pizza dough, for example a few percent.
The distribution device thus implements a series of obstacles opposing the free fall of the ingredients passing through it. Depending on the dimensions and the orientation of said obstacles on the one hand, and the dimensions and the point of impact of each ingredient with at least one obstacle, the path of each ingredient touching an obstacle will be deviated in a random lateral direction.
The obstacles used along the mixing cylinder are arranged to ensure a homogeneous distribution of the ingredients passing through it. To do this, the obstacles are preferably oriented in a plurality of directions - particularly radial - so as not to favor a particular rebound direction.
And preferably, the ingredient distribution device may further comprise a first distribution stage arranged to disperse radially around the longitudinal axis the ingredients from the reservoir or the recovery tank, said first distribution stage being located above or in the upper part of the mixing cylinder.
Advantageously, the first stage is made of a material compatible with food hygiene standards, such as for example stainless steel or polyoxymethylene in copolymer form (Pom-c) for food use.
The first distribution stage makes it possible to obtain a better dispersion of the ingredients at the level of the substrate. Indeed, during the implementation of the distribution device, the tank containing the ingredients is aligned vertically above said distribution device. More particularly, the reservoir is centered with the distribution cylinder, its diameter preferably being smaller than the diameter of the mixing cylinder. When opening the reservoir so that the ingredients it contains fall outside of said reservoir and through the distribution device, it is preferable to project said ingredients to the outer wall of the mixing cylinder so as to better the distribute, especially on the peripheral areas of the substrate.
Preferably, the first distribution stage is arranged to disperse said ingredients radially, without particularly favoring a direction.
According to a particular embodiment, the first distribution stage may comprise a conical surface that extends laterally inside the mixing cylinder, said first distribution stage being aligned co-axially with the mixing cylinder, at least one obstacle being fixed on said mixing cylinder in the extension of said conical surface, so that an ingredient falling along the first distribution stage is projected beyond the conical surface on said at least one obstacle.
This clever configuration makes it possible to guarantee a primer favorable to the distribution of the ingredients in a homogeneous and random manner on the substrate situated below. All the ingredients falling from the tank located above are thus projected laterally towards the periphery of the mixing cylinder, and at least a portion of them, reaching the wall of said mixing cylinder, bounces on a first obstacle and is reoriented preferentially. in a central direction of said mixing cylinder.
According to an advantageous configuration of the first aspect of the invention, the mixing cylinder further comprises separators dividing longitudinally said mixing cylinder into several sectors. It is thus possible to define several regions on the substrate.
The separators comprise, for example, plates oriented on the one hand in the direction of a generatrix of the mixing cylinder, and on the other hand radially to the guide curve of said mixing cylinder, so as to divide the cylinder longitudinally into several sectors. The longitudinal dimensions of the separators are such that they do not protrude from the mixing cylinder. And preferably, the lower edge of the separators is slightly set back relative to the lower edge of the mixing cylinder so as to ensure a lack of contact between the substrate and the separators and a deposit at these separators on the substrate
Separators are advantageously made of a material compatible with food hygiene standards, such as for example stainless steel.
Optionally, a motorized and controlled shutter system of each sector, located above each sector and, where appropriate, under the first distribution stage, may make it possible to prevent the deposition of ingredients on a particular region of the substrate. . According to one particular use, such a closure system of each sector can make it possible to randomly and homogeneously deposit ingredients within a particular sector, thus making it possible, for example, to produce culinary preparations composed of several combinations of ingredients, each of the ingredient combinations being deposited randomly and homogeneously within a particular region of the substrate.
In the case of the distribution of fillings on the surface of a reduced pizza dough, such a closure system can thus make it possible to make a pizza composed of several different recipes on each sector. To do this, the content of the tank initially composed of the ingredients of a first recipe is poured onto the distribution device for which all sectors except one are closed with the aid of the closure system according to this variant of the invention. 'invention. The ingredients are then distributed homogeneously and randomly within said sector and on the lowered pizza dough. Then, the tank is again stocked with the ingredients of a second recipe. These ingredients are then poured through the distribution device which only another sector is allowed to pass, the ingredients then being distributed homogeneously and randomly on the surface of the second sector of the lowered pizza dough. The process is repeated as many times as necessary depending on the number of sectors, the reduced pizza dough and the desired result.
According to another particular use of this variant, it is possible to deposit ingredients on several substrates located under the sampling device. For a better understanding, an example is given for a particular recipe, the latter being in no way limiting the device according to the invention. It is assumed that the tank includes several cereals and several pieces of different fruits and pieces of chocolate. By placing several bowls under the distribution device, and more particularly by placing a bowl under each sector of the mixing cylinder, it is possible to distribute the contents of said tank in the different bowls by alternately opening and closing the shutter system of each sector. .
Optionally, the sampling device can also be placed above a single sector of the mixing cylinder in order to deposit exclusively within said sector at least a portion of the ingredients contained in said tank.
Advantageously, the sampling device can be placed successively above each sector of the mixing cylinder in order to produce successive and specific deposits inside each sector of the mixing cylinder.
Preferably, obstacles can be fixed on the separators of the mixing cylinder, cleverly allowing better homogenization of the ingredients on the substrate. Thus, each sector ensures the random and homogeneous distribution of the ingredients that pass through the corresponding sector of the substrate below, independently of other sectors.
Advantageously, the obstacles may comprise beaters having a plane and / or cylindrical contact surface, such as for example strips and / or rods, said beaters being fixed by at least one of their ends to an inner face of the mixing cylinder. at different heights along its longitudinal axis and extending in a plurality of directions.
The beaters include physical barriers that oppose the free fall of the ingredients within the mixing cylinder. Their dimensions, their orientation, their number and their arrangement inside the mixing cylinder make it possible to ensure a homogeneous radial distribution of the ingredients on the substrate. In general, the obstacle density is such that an ingredient falling inside the mixing cylinder should encounter at least one obstacle during its fall.
The obstacles are distributed according to different heights in order to promote multiple bounces during the drop of the ingredients inside the cylinder.
Preferably, in a plane transverse to the generatrices of the mixing cylinder, the obstacles are preferably oriented in multiple directions in order to optimize the random and homogeneous distribution of the ingredients. This advantageous configuration makes it possible surprisingly to promote the dispersion of the ingredients passing through the mixing cylinder in a transverse direction, and to obtain a better homogeneity of distribution on said substrate.
The obstacles are advantageously made in materials making their use compatible in the agro-food field, such as for example a stainless steel or a polyoxymethylene type material in copolymer form (Pom-C).
The obstacles generally have at least one dimension greater than one of the dimensions of the ingredients that pass through the distribution device. For example, the slats may have a length of between 15 and 30 mm for a thickness less than one millimeter; while the rods may have a diameter of between 0.5 and 3 mm for a length greater than 50 mm.
Typically, the obstacles having a flat contact surface are arranged to allow the ingredients of the outer walls of the mixing roll to be removed.
Complementarily, the obstacles having a cylindrical contact surface are arranged to allow random distribution of the ingredients by agitation to optimize and homogenize their mixture.
Advantageously, the distribution device according to any one of the improvements of the second aspect of the invention can be implemented on the conservation system of the first aspect of the invention. The distribution device is then able to be located in an intermediate position between the recovery tank and the substrate when the recovery tank is in the unloading configuration. In this case, the reservoir from which the ingredients fall through the distribution device may advantageously be the recovery tank of the sampling and dosing device of the preservation system.
According to a third aspect of the invention, there is provided a method for dosing and depositing ingredients on a substrate by means of a preservation and dosing system according to any one of the preceding claims, characterized in that it comprises, for a predetermined selection of ingredients to be sampled: for each compartment comprising at least a part of the ingredients of said selection: displacement of the recovery tank towards said compartment; coupling the sampling and dosing device with the compartment so that ingredients can be taken from said compartment; - taking the predetermined quantity of ingredients contained in said compartment and routing to the recovery tank; when all the ingredients of said selection have been taken: decoupling of the sampling and dosing device with the compartment; - moving the recovery tank in the unloading configuration; - Opening of the recovery tank to dump the ingredients it contained on a substrate placed in the recovery tray.
According to a fourth aspect of the invention, it is proposed to use the system according to any one of the improvements of the first aspect of the invention for selecting and depositing ingredients on a lowered pizza dough.
According to a fifth aspect of the invention, there is provided a machine arranged for the preparation of culinary preparations comprising: a system for preserving and dosing ingredients according to any one of the embodiments of the system according to the first aspect of the invention comprising a dressing station, said ingredients being suitable for use in making said cooking preparations; a cooking device for cooking preparations; a handling system arranged to be able to introduce a support to a cooking preparation in the storage and dosing system and to be able to transfer the culinary preparation of the storage and dosing system to the cooking device; - A processing unit programmed to control said controller so as to prepare a culinary preparation according to a predetermined recipe.
According to this fifth aspect of the invention, the storage and dosing system according to any one of the first aspect embodiments and / or the dispensing device according to any one of the improvements of the second aspect according to the invention. The invention can be integrated into a machine for making "on-demand" and "take-away" culinary preparations, such as an automaton for making pizzas. The system according to the invention can thus be integrated into an automation system and allow on the one hand the selection and the removal of ingredients in predetermined quantities according to particular recipes, and / or on the other hand the deposition and the random and homogeneous distribution of said ingredients taken from a substrate of the culinary preparation, for example a lowered pizza dough. Such an automaton can thus autonomously provide a just-in-time production of culinary preparations for the order and with the customization of the dishes.
Various embodiments of the invention are provided, integrating, according to all of their possible combinations, the various optional features set forth herein.

In particular, all the variants and all the embodiments described are combinable with each other if nothing stands in the way of this combination at the technical level.
In the figures, the elements common to several figures retain the same reference.
Referring to FIGURE 1, the storage and dosing system 100 includes a storage chamber 101, said storage chamber being arranged to retain a plurality of ingredients, preferably stored in separate compartments, each compartment comprising only one type of ingredient.
According to FIGURES 1 and 2, the storage and dosing system according to the first aspect of the invention comprises a storage chamber 101. Inside the storage chamber, a plurality of compartments 110 can store ingredients individually. . A sampling and dosing device 150 makes it possible to take a predetermined quantity of ingredients from each compartment 110 by means of a conveying mechanism. A secondary conveying device 140 makes it possible to enter or exit into the storage chamber 101 a substrate 147 transported by a conveyor carriage 145 from a hatch 146 located on a lateral face of said storage chamber 101. In the unloading configuration, the conveyor carriage 145 is positioned below the distribution device so that the ingredients taken from the sampling and dosing device situated above said distribution device are deposited in a random and homogeneous manner on the substrate 147.
A door, not shown for clarity and located on a front side of the storage chamber 101 allows alternately to open said storage chamber 101 in order to access the compartments 110 located inside, or to close said room conservation 101, preferably in a hermetic manner.
According to an advantageous embodiment, the preservation chamber 101 may comprise refrigeration or freezing means (not shown) in order to maintain a temperature adapted to the storage of the stored ingredients.
The preservation chamber 101 comprises a plurality of compartments 110. The compartments are preferably organized into a plurality of lines HOa-11Of and extend from a side face of the preservation chamber 110 in the direction of the opposite lateral face. The space between two consecutive lines is sufficient to allow the sampling and dosing device 150 to move between the compartments 110, and collaborate with them. Laterally, the compartments 110 are preferably juxtaposed with each other in order to minimize the occupation of the internal volume of the preservation chamber 101.
Advantageously, all the compartments of the same line have the same dimensions, each line may comprise a different number of compartments. In the example illustrated in FIG. 1, the first line 110a comprises only two compartments whereas the lines HOb-11Of each comprise eight compartments. On the other hand, in the example illustrated in FIG. 1, the heights of the compartments of each line are all different, the heights of the compartments of the upper lines being lower than the heights of the compartments situated on the lower lines. The compartments will be described in more detail in FIGURE 2.
The sampling and metering device 150 comprises a conveying mechanism which makes it possible to move a collection tank 150 between each compartment 110 in order to collaborate with one of them to take a predetermined quantity of ingredients.
The conveying mechanism illustrated in FIGS. 1 and 2 comprises two axes of displacement, according to which the sampling and dosing device 150 can be actuated alternately or simultaneously as required, in particular in order to minimize the time of movement between two compartments 110. The first axis of displacement is aligned with the largest dimension of the preservation chamber 101, in this case vertical. It is embodied by two main rails 112a and 112b respectively fixed on two opposite walls of the storage chamber 101 by means of fixing means.
On each of the main rails 112a and 112b, a sliding pad 111a and 111b is mounted in a slide connection to enable it to move along the corresponding main rail. A drive member 105, formed of two motors 105a, 105b, makes it possible to control the displacement of each sliding pad 111 along the corresponding main rail. The motors 105a and 105b can be synchronized.
A secondary rail 113 connects the two sliding pads 111 in order to define a second axis of movement of the sampling and dosagel50, transversely to the main rails 112.
Similarly, a sliding shoe 114 is mounted through a sliding connection on the secondary rail 113 in order to be able to move along said secondary rail 113, transversely to the main rails 112.
The sliding pad 114 supports the sampling and dosing device 150 which will be described in more detail in FIG. 2.
Advantageously, the preservation chamber 101 further comprises at least one distribution device 130 in order to randomly and homogeneously distribute the ingredients taken by the sampling device on a substrate. In the example illustrated in FIG. 1, three distribution devices 130 are shown, each distribution device having a diameter different from that of the others in order to adapt to different sizes of substrate and to optimally distribute the ingredients taken from said substrates. Each distribution device 130 is arranged in such a way that the sampling and dosing device 150 can be moved over each distribution device 130.
Below the distribution devices 130, the motorized secondary conveying device 140 makes it possible to move a substrate 147 towards the inside of the preservation chamber 101, and more particularly below a distribution device 130.
FIGURE 2 depicts a detail view of the sampling and dosing device 150 collaborating with a compartment 110 for taking ingredients. It comprises a flared receptacle 151 and a receptacle 152 located below the flared receptacle 151. The flared receptacle 151 is oriented so as to have a wide opening upwards, and a reduced opening downwards, this reduced opening being connected to the receptacle 152.
The dimensions of the container 152 are such that it can contain all the ingredients taken in a predetermined quantity from a plurality of compartments. These dimensions are for example adapted to contain all the ingredients of the culinary preparation requiring the largest volume of ingredients. The ingredients successively taken from the plurality of compartments are thus temporarily stored in the container 152 in successive layers.
A weight sensor 160 makes it possible to monitor in real time the evolution of the weight of the ingredients which have fallen in the container 152. It thus makes it possible to control the sampling and dosing device 150, and more particularly the motor member 155 which controls extracting the ingredients from each compartment 110. For each sample, when the predetermined quantity of ingredients is reached - by estimating the weight of the container 152 - the drive member 155 tilts the extraction member 1552 into a closed configuration .
Preferably, the weight sensor is arranged to detect the drop of ingredients inside the container 152, and more particularly arranged to detect the weight of each ingredient falling on the flared receptacle 151. In the sampling configuration, the device for sampling and dosing is advantageously arranged so that the flared receptacle 151 is located in a position such that each ingredient extracted from the compartment falls on the inner surface of said flared receptacle 151, no ingredient falling directly into the container 152 without touching the inner surface. In this way, it is possible to determine the instantaneous weight of the ingredients extracted from the compartment and to precisely control the stopping of said extraction of ingredients when the predetermined amount of ingredients is reached. The motor member 155 comprises a motor 1551, a first pulley 1552, a belt 1553, a second pulley 1554, a connecting element 1555 and a connection piece 1556. The motor is arranged to drive the first pulley 1552 in rotation, rotational movement being transmitted to the second pulley 1554 via the belt 1553. The rotational movement is then transmitted from the second pulley 1554 to the connection piece 1556 via the connecting element 1555. The connecting piece 1556 is arranged to be able to collaborate with an extraction member 182 pivotally connected to the compartment 110. The drive member 155 and the extraction member 182 thus make it possible to tilt said compartment 110 alternately in the sampling or storage configurations described above.
The weight sensor can be of any type, for example optical, capacitive or resistive.
Preferably, the weight sensor 160 is of the type of a balance, the recovery tank being mounted on said balance via a fixing ring 162, the balance 160 being fixed integrally by means of a lever 161 to a support plate 163 of the sampling and dosing device 150.
Preferably, a mechanical damping system is provided to reduce the mechanical vibrations during use of the sampling and dosing device. An electronic or software filtering system of the signals generated by the measuring sensor can also be used, instead of or in addition to the mechanical damping system, to reduce the measurement noise and to improve the accuracy of the weight measurement. in fine, taking the ingredients from each compartment.
On its bottom, the container 152 includes a retaining mechanism 168 for retaining the ingredients 157 contained in the container 152 in a closed position, and emptying the container 152 in an open position. Preferably, the opening time of the retaining mechanism 168 is very short so that all the ingredients begin to fall at the same time, especially those located at the peripheral zones of said container 152 and those located in the center.
In the example illustrated in FIG. 2, the retaining mechanism 168 comprises two hatches (visible in FIG. 4) pivotally connected to the container 152. The hatches are held in the closed position by an elastic force. They can be tilted into the open position by applying a downward force.
With reference to FIGURES 2, 3A and 3B, two particular embodiments of compartments will now be described, as well as their ingredient extraction element.
The illustrated compartment 110 is arranged to contain a quantity of ingredients for the preparation of several culinary preparations. In its upper region, it comprises a reservoir for storing said ingredients and, in its lower part, it comprises an extraction element making it possible to extract a predetermined quantity of ingredients in a controlled manner.
A compartment comprises in its upper part a parallelepiped shape for storing a relatively large amount of ingredients. The upper portion of the compartment 110 can be closed with a removable cover (not shown) to allow both a visual check of the ingredients it contains, and easy filling.
Preferably, the overall shape of the compartment 110 is rather slender upwards, with a height greater than the other two dimensions (width and depth) so that a large part of the stored ingredients is superimposed and a reduced portion said stored ingredients reaches the lower region under the simple effect of gravity.
In its lower region, the compartment 110 comprises a hood 181 of concave shape for retaining stored ingredients by preventing them from falling under the effect of gravity. The cover 181 closes at least in part the transverse section of the parallelepipedal portion of said compartment 110.
Preferably, the cover 181 has a shape allowing the insertion of an extraction element. In the example illustrated in FIGS. 2 and 3, the extraction element 182 is a worm type mechanism. The screw is held between the rear face of the compartment 110 (not visible) and a front support 183 kept at a distance from the compartment 110 by means of two lateral uprights 184 and 185.
Preferably, the concave shape of the cover 181 envelops the helical winding of the screw 182 in order to promote the advancement of the ingredients in the direction of the front support 183, and more particularly in the direction of the drop zone 188 formed by the free space left by the hood 181.
As can be seen in FIG. 2, the sampling and dosing device 150 is preferably arranged in its sampling configuration so that the flared receptacle 151 is located in line with a drop zone 188 so that all the ingredients collected fall into said flared receptacle 151.
In each of the embodiments of FIGS. 3A and 3B, the screw 182 is mounted free to rotate between the rear face of the compartment 110 and the front support 183. It can be actuated by the motor member 155 which, as mentioned previously, can alternatively mounted on the compartment, for example at the rear face of said compartment, or at the sampling and dosing device 150 (visible in Figure 2).
At the front support 183, the screw 182 is coupled in rotation with a connection element 186 which makes it possible to collaborate with the sampling and dosing device 150, and more particularly with the connection piece 1556. Thus, when the sampling and metering 150 arrives close to the compartment 110, the latter establishes a rotational coupling between the connection piece 1556 and the connection element 186. Thus, the sampling and dosing device 150 collaborates with the compartment in order to extracting the predetermined quantity of ingredients, by actuating the drive member 155 situated either on the compartment 110 or on the sampling and dosing device 150.
In the embodiment of FIG. 3A, the connection element 186A takes the form of a rod integral in rotation with the screw 182. A partial shut-off element 115 is also arranged at an outlet orifice of the The closure member 115 comprises a set of resilient tabs extending concentrically from the periphery of the outlet port. In the embodiment of Figure 3B, the connecting member 186B takes the form of a disc having a plurality of openings. The connection piece 1556B of the sampling and dosing device 150 may then comprise a set of fingers capable of coming to mate in the openings of the connection element 186B.
Optionally, the connection piece 1556 and the connecting element 186 are arranged to first establish a temporary coupling in rotation, with friction, in order to act as a clutch, then a coupling in rotation by engagement to guarantee the mechanical connection between the motor member and the extraction element.
Advantageously, the sampling and dosing device 150 may comprise a motorized translation axis arranged to be able to move said sampling and dosing device so as to couple or uncouple the motor member of the extraction element.
With reference to FIGURE 4, the distribution device according to one aspect of the invention will now be described, FIGURE 4 illustrating a detailed view of the distribution device placed in an unloading configuration, the recovery tank being placed at above the distribution device.
As shown in FIG. 1, the preservation chamber 101 comprises three distribution devices 130, referenced 130a, 130b and 130c.
Each distribution device 130 comprises a mixing cylinder 134 capable of being placed above the substrate 147, the longitudinal axis of the mixing cylinder 134 being substantially perpendicular to the surface of the substrate 147.
The lateral dimensions of each mixing cylinder 134 are adapted to the lateral dimensions of the substrate 147 on which the ingredients 157 must be deposited, so that all the ingredients passing through the distribution device 130 fall on the substrate 147. More particularly, the outer diameter of the mixing cylinder 134 is smaller than the smallest outer lateral dimension of the substrate on which the ingredients are to be deposited.
In the example illustrated in FIG. 1, the storage chamber 101 comprises three distribution devices 130: the outside diameter of the first mixing cylinder 134 a is 25 cm, the diameter of the second mixing cylinder 134 b is 20 cm, and that of the third mixing cylinder 134c is 14 cm.
Each distribution device 130 is fixed integrally to the preservation chamber 101, via an upper support 139a and a lower support 139b visible in FIG. 1. Each distribution device 130 is arranged to allow the device to sampling and dosing 150 to move alternately above each mixing cylinder 134 in a configuration allowing the ingredients contained in the container 152 to fall inside one of the mixing cylinders 134.
More particularly, an opening system 132 positioned vertically above each mixing cylinder 134 makes it possible to define a so-called deposition position in which the container 152 is preferably concentrically aligned with the mixing cylinder 134 and arranged to trigger the opening. opening of the retaining mechanism 168, and in particular traps 1683a and 1683b. More particularly, the opening system 132 comprises a support plate 1321 on which the hatches 1683 can bear following a vertical displacement of the sampling and dosing device 150 upwards. This support causes the opening of the flaps 1683, and therefore the drop of the ingredients 157 contained in the container 152. The closing of the flaps 1683 is actuated by moving the sampling and dosing device 150 downwards, to a position in which traps 1683 are no longer supported on the bearing surface 1321.
The mixing cylinders 134a and 134b comprise on their respective upper part a first distribution stage 133a and 133b in the form of a cone whose apex is substantially aligned with the axis of symmetry of the cylinders 134a and 134b. In the example illustrated in FIGURE 1, the top of each cone 133 is substantially aligned with the upper edge of the corresponding corresponding mixing cylinder 134.
Each mixing cylinder 134 comprises, between its upper end and its lower end, obstacles 136-137 arranged to oppose the free fall of the ingredients, so as to generate a lateral random displacement and to distribute them randomly and homogeneously on the surface of the substrate below (not shown).
In the case where a first distribution stage 133 is implemented, the obstacles 136-137 are all located below said first distribution stage 133, and preferably, they are all located below a position along the inner wall of the mixing cylinder 134 corresponding to the intersection of the extension of the conical surface of the first distribution stage with said inner surface of the mixing cylinder 134.
In the example illustrated in FIG. 4, the obstacles 136-137 complementary take the form of prisms 137 fixed by a first side on the inner surface of the mixing cylinder 134 and having a contact surface inclined upwards and inwardly of said mixing cylinder 134 corresponding, or rods 136 fixed by at least one of their end to the inner face of the mixing cylinder 134. In general, the obstacles 136-137 are positioned, in order to optimize the distribution, and at different heights along a longitudinal axis of the distribution device 130, said obstacles 136-137 extending in a plurality of directions.
More particularly, the prisms 137 are disposed on the peripheral inner periphery of the mixing cylinder 134, in a first so-called rebound plane positioned on the upper part of the mixing cylinder 134. In the particular case illustrated in FIG. first rebound plane is defined by a position corresponding to the intersection of the extension of the conical surface of the first distribution stage 133 with said inner surface of the mixing cylinder 134. This configuration advantageously allows and to obtain an excellent lateral distribution at the level of substrate below.
The mixing cylinders 134 may comprise other distributed prisms to optimize the distribution of ingredients below this first rebound plane.
The rods 137 are preferably all oriented downwards to prevent certain ingredients falling inside the mixing cylinder 134 from getting stuck on these rods.
The rods 137 may be rectilinear or curved, depending on the desired effect.
In the example illustrated in FIG. 4, the distribution device 130 further comprises separators 135 which define, in a plane transverse to the longitudinal axis of the mixing cylinder 134, at least two sectors. More particularly, the distribution device 130 comprises four separators 135a distributed at 90 ° around the central longitudinal axis and dividing said distribution device 130 into four identical sectors.
Alternatively, a distribution device 130 may comprise, for example, three separators 135 distributed at 120 ° around the central longitudinal axis and dividing said distribution device 130b into three identical divisions.
Alternatively, a distribution device 130 may also not include such separators.
Some of the obstacles 136-137 are also fixed on either side of the separators.
As can be seen in FIG. 7, in a plane transverse to the longitudinal axis of a mixing cylinder 134, the distribution of obstacles 136-137 and their typology are arranged in such a way that the distance between two obstacles is slightly greater than characteristic dimensions of the ingredients that fall inside the mixing device 130.
Indeed, if this distance is too large, then the probability of rebound of an obstacle falling inside the mixing cylinder 134 is too low and the distribution of said ingredients on the surface of the substrate is not optimal. Conversely, if, in the transverse plane, the distance between two obstacles is much smaller than the characteristic dimensions of the ingredients that fall inside the mixing cylinder 134, then the likelihood that ingredients will get stuck at the same time. interior of said mixing cylinder 134 is too large. In this case, the deposition of the ingredients on the surface of the substrate is not optimal either.
Advantageously, the distribution device according to the invention can be implemented on the storage system described in FIG. 1. In this case, the reservoir from which the ingredients fall through the distribution device may advantageously be the device recovery tank. sampling and dosing 150 of the preservation system 100.
FIGURE 5 describes the use of a preservation and dosing system 100 according to any of the improvements mentioned above in a system for the automatic preparation of culinary preparations, and more particularly pizzas.
The preservation and dosing system 100 can be integrated into a controller 500 producing the preparation, cooking, and / or packaging and / or delivery of cooking preparations, and especially pizzas.
Thus, such an automaton can comprise: a system for preserving and dosing ingredients 100 as described with reference to FIG. 1, said ingredients being able to be used for making said culinary preparations; a cooking device 502 for cooking preparations; a handling system 504-506 arranged to be able to transfer at least one of the upright culinary preparations, in particular between the preservation and dosing system 100 and the cooking device 502; - A programmed processing unit (not shown) for controlling said controller 500 so as to prepare a culinary preparation according to a predetermined recipe.
For ease of understanding, an example will be given for the preparation of a pizza, the automaton being however arranged to make a wide variety of culinary preparations, as mentioned above.
In the example illustrated in FIG. 5, the automaton also comprises a fresh dough tank 508, a formator 501 for lowering the dough used for making said pizza; and the handling system used comprises in particular three multiaxis robotic arms 504-506 and a conveying device 140 between a fresh paste forming device 501 and the storage and dosing system 100. The robotic arms are arranged to handle the pizza being made, for example by means of a shovel (flat) 509, and to transfer it from one station to another.
Thus, in a first step, a predetermined amount of dough - preferably fresh - is removed from the tank 508 to form a dough. This predetermined amount is dimensioned so as to flatten the dough to the desired dimensions of a pizza.
To do this, the dough is transferred to a forming device 501 which gives it the desired shape. In this case, the dough gives a so-called lowered dough, from which the pizza will be made.
Optionally, a sauce (eg tomato or cream) is poured and spread to prepare the substrate.
Then, the dough thus prepared is transferred inside the preservation and dosing system 100 by a conveyor trolley 145. The latter is moved by the conveying device 140 to a position located in line with the one distribution devices 130 so that certain ingredients are deposited therein. These ingredients are taken in predetermined amounts from certain compartments 110 located in the storage chamber.
Preferably, the deposition of said ingredients is carried out randomly and homogeneously on the surface of the pizza using a distribution system 130.
Then the pizza is transferred to and loaded into the baking device 502 for baking. Depending on the type of pizza baked, the cooking parameters are determined. These parameters include in particular at least one duration and at least one power cycle. A cooking cycle can include several variable or constant cooking regimes.
When a pizza arrives at the end of the cooking cycle, the door of the cooking device 502 is opened for as short a time as possible, and during which one of the robotic arms, for example the robotic arm 504 grasps said pizza.
