    Descriptive Report of the Invention Patent for CAPSULE SYSTEM FOR THE PREPARATION OF BEVERAGES BY CENTRIFUGATION AND METHOD OF BEVERAGE PREPARATION USING A CAPSULE.
    [0001] The present invention relates to the preparation of beverages, in particular coffee, from capsules in a preparation device by means of centrifugation of the capsule.
    [0002] There are systems for the preparation of this type of drink such as coffee through the forced passage of the liquid through the ingredients contained in the capsule using centrifugal forces. A possible solution is described in WO2008 / 148604.
    [0003] EP1208782A1 relates to a device for preparing coffee drink from capsules of different sizes. The volume of the capsules is obtained by extending the capsule body on its open side, thus producing different capsules of larger diameters. As a result, the adaptation of the capsule to the device is complex and requires moving elements to ensure proper tightness. In a centrifuge device, this would create wear and tear between the device after a certain period of use and produce vibrations when the capsule is centrifuged.
    [0004] In a centrifugal system, an additional risk exists when creating vibrations if the capsule is not properly attached to the centrifugal device. For a capsule set having different volumes and containing different amounts of ingredient, there is an increased risk of imbalance and, consequently, a risk of producing vibrations. The preparation device can move when it vibrates and can generate a very important noise. In addition, the lack of support in supporting the capsule support can cause deformation of the capsule during centrifugation and create a potential failure of the container, in particular, in plastic capsules.
    Petition 870200010656, of 23/01/2020, p. 5/33
    2/20 [0005] Therefore, there is a need to provide a capsule system that is able to conveniently deliver a greater variety of drinks, especially coffees having different characteristics (flavor, intensity, cream, etc.) in the centrifugal preparation device .
    [0006] The present invention provides a solution to the problems mentioned above, as well as offering additional benefits to existing techniques.
    [0007] To this end, the invention relates to a capsule system for the preparation of beverages by centrifuging a capsule in a centrifugation preparation device comprising:
    a set of different capsules; each to selectively deliver a drink having specific characteristics that differ from other capsules in the set; each capsule in the set comprising a body with a side wall and a free margin, an upper wall and an extraction or infusion ingredient; and an insertion diameter (D) of the capsule body for insertion into a capsule holder of the preparation device in a reference position, in which different capsules in the set have different bodies of different storage volumes obtained by varying depth of the body of the set, but the same insertion diameter (D) for all capsules in the set.
    [0008] The term "insertion diameter" refers to the diameter of the reference measured on the outer surfaces of the capsule body.
    [0009] Such a configuration of capsules makes it possible to provide a more extensive range of beverages, for example, ristretto, espresso and lungo coffees (or even larger volumes of coffee) in a more convenient way. In particular, the geometric configuration capsules make it possible to accommodate different volumes in the same preparation device
    Petition 870200010656, of 23/01/2020, p. 6/33
    3/20 without requiring specific device adaptations.
    [00010] In one mode, the different capsules in the set have at least one upper body having substantially the same angle or the same stepped profile in the set. The term "angle" means the angle of the portion in the axial direction (or the line of curvature in the axial direction for the non-straight profile of the upper body portion) of the capsule with respect to the central axis of rotation of the capsule.
    [00011] The upper body portion may be, for example, a truncated or cylindrical portion.
    [00012] In mode, the body comprises a lower portion of variable length whereas the upper portion may be of constant length for all capsules in the set. The lower portion can be convex, flat or concave.
    [00013] By convention, the term “upper portion” means the portion of the body closest to the free margin of the body and the term “lower portion” means the portion of the body towards the bottom of the capsule body.
    [00014] In another way, different capsules of the set have a body that is convex along its entire surface and has a variable depth in the set. In this mode, the upper and lower portions of the body are not distinct portions, but merge into a single convex portion.
    [00015] Preferably, the amount of infusion or extraction ingredients increases depending on the volume of storage (that is, depth) of the body increasing as a whole. As a result, each capsule in the set can provide drinks of different volumes and with different characteristics. The term "characteristics" when referring to the drink means any attribute of the drink that makes a difference, such as related to taste, strength, foam or cream, color, etc. Such attributes can be measured by any analytical measures
    Petition 870200010656, of 23/01/2020, p. 7/33
    4/20 appropriate or displayed by any sensory or visual test.
    [00016] In particular, the different capsules contain roasted and ground coffee and have different characteristics of roasting and / or grinding in the set. The capsules can be adapted to deliver different types of coffee such as ristretto, espresso, lungo, etc., or coffees of the same type, but with different characteristics, for example, different flavors or cream.
    [00017] The capsule system also comprises an identification means associated with the different capsules in the set to identify each capsule and consequently adjust the preparation parameters. The adjustable parameters can be chosen from one or more of the following parameters: the rotational speed, the flow rate, the back pressure at the capsule outlet, and / or the volume of the liquid fed into the capsule. The means of identification participates in the provision of a wider range of drinks having different characteristics (volume, flavor, strength, cream, color, etc.). The means of identification are associated with the control means positioned on the preparation device that controls the setting. of said parameters, when controlling the rotational motor by activating the capsule support and / or the pump supplying liquid in the capsule.
    [00018] In another feature of the invention, the preparation device comprises of a rotating capsule support with a support surface arranged to provide support to the body portion of the capsule in the assembly; said side wall portion comprising a reference diameter corresponding to the diameter of insertion of the capsules. For this, the support surface of the capsule thus comprises a reference diameter that corresponds to the diameter of insertion of the capsules in the set in order to keep any capsule in the set in the same reference position. This same position can be determined, for example, for example, by a position of
    Petition 870200010656, of 23/01/2020, p. 8/33
    5/20 reference of the free margin of the capsule body along the reference plane (P) before closing the preparation unit. In addition, the supporting support surface of the capsule supports an upper body portion of different capsules in the assembly whereas it does not provide support for a lower body portion of the capsules.
    [00019] As a result, the risk of producing vibrations during centrifugation is reduced because all capsules in the set are tightly fitted on the device with limited possible relative movement between each capsule and the device during rotation, that is, the capsule support.
    [00020] The invention also relates to a capsule for the preparation of a drink by centrifugation on the rotating capsule support of a centrifugation preparation device comprising a body with a side wall and a free margin, an upper wall and an ingredient of extraction or infusion; and an insertion diameter (D) in the capsule body, such an insertion diameter (D) being positioned at a certain distance below the free margin of the body to match the reference diameter of the support surface of the rotating capsule support and provide a self-locking of the capsule when inserted in the capsule holder.
    [00021] Preferably, the capsule comprises an upper portion extending from said diameter (D) which has an angle (α) just below the angle (p) of the support surface of the capsule support.
    [00022] The angle (α) of the upper portion is preferably 1 to 8 degrees, more preferably 1 to 5 degrees, lower than the angle (β) of the support portion of the capsule support.
    [00023] Such a configuration allows to form a self-locking function of the capsule in the capsule holder when the
    Petition 870200010656, of 23/01/2020, p. 9/33
    6/20 closure is applied to the edge of the capsule, consequently reducing the risk of vibrations during the centrifugation process. [00024] By convention, the "angle" refers here to the angle that the said surface forms, in the axial direction of the capsule, with respect to the central axis of the capsule body, corresponding to the axis of rotation. It should be noted that the measured surfaces could not be purely straight, but could have a slight line of curvature without departing from the scope of the invention.
    [00025] In addition, in addition to the firm support of all capsules to prevent vibrations, the capsule support can be hollow in its center to accommodate all capsules in the set. In another way, the capsule holder could have a bottom wall that is deep enough to receive a longer (i.e., deeper) set of capsules. The advantage is that essentially a single capsule holder is sufficient to receive all capsules in the set.
    [00026] The present invention further relates to a beverage preparation system using a capsule that is centrifuged in a centrifugal preparation device comprising:
    [00027] A set of capsules composed of different volumes, identification means corresponding to different capsules in the set, a centrifugal preparation device comprising control means capable of operating the device in centrifugation for any capsule in the set according to predetermined preparation parameters including at least one of these parameters: the flow rate, the rotational speed, the volume of liquid injected into the capsule and any combination of these.
    [00028] In particular, the control means is capable of operating the device of any capsule in the set including: the flow rate and
    Petition 870200010656, of 23/01/2020, p. 10/33
    7/20 the volume of liquid injected into the capsule.
    [00029] In other words, for each capsule in the set corresponds to the reference index or a flow rate profile (for example, any value between the range of 0.2 and 10 ml / sec) and a particular volume of liquid injected (for example, 25, 40, 120, 230 or 400 ml). Certain values of flow rates or volumes may be common for different capsules in the set.
    [00030] In particular, the flow rate is controlled by the variation in rotational speed and / or the back pressure exerted on the centrifuged liquid by restricting the flow of the device and / or the capsule.
    [00031] For example, for drinks such as coffee, the flow rate can vary from 0.2 ml / s to 10 ml / s thereby providing a wide range of coffee characteristics.
    [00032] The flow rate is preferably controlled as a function of the volume of the capsule. Preferably, the smaller the amount, the lower the flow rate.
    [00033] Control can also be achieved through passive means such as an identifiable shape or opening characteristics of the capsule which alters the counter pressure of the flow restriction medium. For example, capsules of different volumes in the set can be of different cross sections of outlet and providing different values of backpressures exerted on the centrifuged liquid.
    [00034] Preferably, the system of the invention contemplates adjustment by controlling the volume of liquid injected and the rotational speed and, optionally, the counter pressure by means of selective flow restriction.
    [00035] The identification means are identified by the control means to operate the device.
    Petition 870200010656, of 23/01/2020, p. 11/33
    8/20 [00036] The identification means can be felt by the sensing means connected to the control means for an active control of the parameters or it can be a passive means of identification, for example, selective flow restriction means.
    [00037] In particular, the identification means comprises of recognition capsule means which are recognized by sensing means connected to the control means of the production device which controls the production parameters appropriately.
    [00038] The means of recognition can be distinguished by a visual code such as a bar code, a color, a symbol, a logo, etc., or by the radio frequency code (RFID), a magnetic element or by an identifiable shape .
    [00039] The invention further relates to a method of preparing a drink using a capsule that is centrifuged in a centrifugation preparation device comprising:
    providing a set of capsules having different volumes, selecting a capsule from the set of capsules and centrifuging said capsule in the preparation device for preparing the drink.
    wherein at least one of the following parameters: flow rate, rotational speed and volume of the injected liquid is adjusted as a function of the selected volume of the capsules.
    [00040] Preferably, the flow rate and volume of injected liquid is adjusted as a function of the selected volume of the capsule.
    [00041] In another mode, the rotational speed and volume of the liquid injected into the capsule are adjusted as a function of the volume of the selected capsule.
    [00042] The method includes adjusting the flow rate by adjusting the rotational speed and / or the back pressure exerted on the liquid
    Petition 870200010656, of 23/01/2020, p. 12/33
    9/20 centrifuged. In other words, the flow rate is kept as close as possible to a set value or varied according to the pre-adjusted profile, during beverage preparation, by adjusting the rotational speed and / or the back pressure exerted on the centrifuged liquid .
    [00043] Alternatively, the means of identification can be formed as the means of selecting a user interface.

    [00045] The capsule system of the present invention illustrated in figures 1 to 5 comprise a set of capsules 1A, 1B of different volumes, but with the same insertion diameter "D". The capsule of figure 1 shows a small volume capsule 1A while the capsule of figure 2 shows a capsule 1B of larger volume. The two capsules comprise of a body 2 having a cup shape with a free margin 3 extending outwards and an upper wall 4. The upper wall is connected to a free margin of the body by the seal such as a welding line or by heat or ultrasonic. The upper wall can be a perforable membrane, a porous wall or a combination thereof. The capsules comprise a central axis “I” which represents the axis of rotation
    Petition 870200010656, of 23/01/2020, p. 14/33
    11/20 during the centrifugation of the capsule in the preparation device (figure 3).
    [00046] The difference in volume between small and large capsules is obtained particularly by varying the depth (d1, d2) of the capsule body in the set. In particular, the depth of the body of the smaller capsule 1A is less than the depth of the body of the larger capsule 1B. In the present example, a single body portion of the smaller capsule 1A is less than the depth of the body of the larger capsule 1B. In the present example, a single truncated body portion is provided which part of the diameter D and extends towards the base 6 of the capsule. The body portion of the capsules 1A and 1B are identical and form a single "A" angle. The angle can vary from 1 to 55 degrees in relation to the central axis I. The insertion diameter “D” is determined here on the line of intersection between the lower surface and the free margin 3 and the upper portion of the body.
    [00047] The small volume capsule contains a quantity of extraction and infusion ingredients, for example, ground coffee, less than the volume quantity in a large capsule. The small capsule 1A is designed to supply a small volume coffee of about 25 ml and 60 ml with an amount of ground coffee comprising between 5 and 15 grams. The larger 1B capsule is designed to provide a larger volume coffee, that is, over 60 ml (for example, between 80 and 500 ml) and contains a quantity of ground coffee between 8 and 30 grams.
    [00048] Capsules 1A, 1B are intended to be inserted in the centrifugal preparation device 7 (figures 4 and 5). As shown in figure 4, the device comprises a preparation unit 8 fed with heated liquid, preferably hot water, by a fluid circuit 9 comprising a heater 10, a pump 11 for measuring the liquid in the capsule and the liquid supply, eg .: one
    Petition 870200010656, of 23/01/2020, p. 15/33
    12/20 water reservoir 12. The preparation unit comprises an interface of the assembly 13, a capsule holder 14 and a collector 15. A peripheral outlet 29, forming a flow restriction for the centrifuged liquid, is provided at the periphery of the capsule, for example, between the interface assembly 13 and the capsule or capsule holder 6. The flow restriction can be formed by a spring-tilted valve located and acting on the margin of the capsule as described in patent WO2008 / 148656. Part of the valve can be formed by the capsule itself as described in co-pending European patent No. 08171069.1. Such flow restriction provides a back pressure in the centrifuged liquid. The collector ends at the exit of the formed drink 16 as formed as an open duct directed to the cup. The capsule support 14 is designed with the portion 24 forming a support surface 18 that is complementary in shape to the upper body of the capsule portion 1A, 1B.
    [00049] In particular, the capsule holder has an annular reference line substantially equal to the diameter "D" in order to ensure a perfect fit of the capsule in the capsule holder without a possible radial oscillation that could provide an imbalance and, consequently, vibrations during centrifugation. The capsule also rests solidly on the top edge on its top edge on the top flange of the support without the body being deformed radially. In this configuration, the preparation unit is closed on the top wall of the capsule by the interface assembly 13. The assembly 13 comprises a central injection needle 20 capable of being inserted precisely along the axis of rotation I of the capsule. At its periphery the assembly 13 may comprise a series of outlet perforators as described in WO2008 / 148604 in order to allow the centrifuged beverage to exit the capsule through the peripheral outlet 29 between the capsule holder 14 and the interface assembly 13 .
    Petition 870200010656, of 23/01/2020, p. 16/33
    13/20
    A device without an outlet punch can be considered when the capsule has a permeable upper wall. Similarly, the injection needle can be optimized and replaced with a simple injection orifice if the upper wall is also permeable. Preferably, the outlet 29 forms a flow restriction provided in the flow path of the beverage to provide a pressure gradient in the capsule.
    [00050] Such a restriction can be obtained through small orifices or a restriction valve as described in WO 2008/148646. [00051] As illustrated in figures 4 and 5, the capsule support can be hollow in its center to allow different volumes (that is, as obtained in bodies of varying depth) of capsules to be inserted in it. The capsule holder can also be closed or a partially closed base.
    [00052] In this case, the depth of the capsule support is at least equal to the depth of the largest capsule in the set (i.e., deeper), for example, capsule 1B.
    [00053] The extraction of the drink from the capsules 1A or 1B is obtained by activating the interface assembly 13 and capsule support 14 together with the capsule, in rotation (R) along axis I, at a relatively high speed, by for example, between 500 and 15000 rpm. The rotation is driven by a rotation motor (not shown). The liquid is forced to pass through the ingredient and leave the capsule at an upper periphery of the capsule, that is, through the outlet perforations provided in the upper wall of the perforators 21. Since many perforators are positioned equally on the periphery of the upper wall, the liquid it can also come out by creating a laminar flow of the beverage dispersed radially along the entire periphery of the upper wall. The centrifuged liquid is projected between the margin of the capsule and the upper surface of the interface assembly 13 against the collector 8. The liquid drink is then
    Petition 870200010656, of 23/01/2020, p. 17/33
    14/20 collected and dispensed through duct 16.
    [00054] Figures 6 and 7 show a second embodiment for another set of capsules in which the capsules 1C, 1D comprise an upper portion 26 and a lower portion 22 of the body forming an extension to vary the depth d1, d2 of the capsule. The upper portion 26 forms a truncated portion comprising the same insertion diameter D necessary to reference the capsule in the capsule holder and a constant angle. The lower portion may be different in shape from the truncated shape and may, as shown, be a convex portion. In the large-volume capsule 1D, the depth d2 of the capsule is increased by a longer (i.e., deeper) lower portion 22. In the smaller volume capsule 1C, the depth d1 of the capsule is reduced by a shorter lower portion 22.
    [00055] Figures 8, 9 and 10 show a third embodiment for another set of capsules according to the invention in which the body has a single convex portion 23a, 23b, 23c of varying depth, respectively, d1, d2, d3. The portion can be continuously convex for certain capsules in the set (eg, capsule 1E, 1F) without a truncated or cylindrical portion zone. The larger 1G capsule may comprise a truncated or cylindrical top portion.
    [00056] In the embodiment of figures 11 and 12, the capsule support 3 of the preparation device comprises from a first portion 24 forming the surface support 18 to the upper portion 26 of the capsules and the lower portion of the portion 25 forming a sealing surface below the capsule of sufficient length to accommodate both the smaller 1H capsules (figure 11) and the larger 1I capsule (figure
    12). As an example, the smaller capsule has a storage volume between 25 ml, and the medium size capsule has a storage volume of 30 ml and the large capsule has a
    Petition 870200010656, of 23/01/2020, p. 18/33
    15/20 40 ml storage volume.
    [00057] In this embodiment, the smaller and larger capsules 1H, 1I may comprise an upper portion 26, for example: from the same angle. The length of the upper portion 26 may be the same or may also vary slightly in order to sufficiently match the surface 19 of the capsule support. The larger capsule 1I may comprise a portion 27 forming an extension portion that can be formed at a different angle (preferably smaller in relation to the axis I), for example, a cone stem or a cylinder with a diameter smaller than the diameter insertion “D” (figure 12).
    [00058] It is clear that the number of capsules of variable depth is not limited to the set in all the described modalities.
    [00059] Of course, in all modalities, the truncated portion can be replaced by a succession of staggered portions or another arbitrarily / equivalent equivalent formed forming a diameter reduction towards the bottom of the capsule that is equivalent to an incomplete continuous surface .
    [00060] In the embodiment of figures 13 to 14, in contrast to the previous embodiment, the capsules of the set are referenceable in a capsule holder with the insertion of diameter D which is positioned at a distance below the edge of the capsule in an upper portion of the wall side of the body. The insertion diameter D is constant in all capsules in the set. Capsules of different volumes 1J, 1K and 1L are illustrated in position on the capsule holder before closing the preparation unit (smaller capsule 1J and deeper capsule 1L are represented only in dotted lines and capsule of medium volume 1K is represented by lines solid). As can be seen, all capsules are maintained at their insertion diameter D along a constant reference position. More
    Petition 870200010656, of 23/01/2020, p. 19/33
    16/20 particularly, all capsules in the set have their upper margins appearing along a common reference on the P plane. On the contrary, the introduction of depth (d1, d2, d3) of the body varies in the capsule support to adapt the volume properly.
    [00061] In this mode, it is advantageous to design the upper portion so that its inclination angle α is slightly lower than the angle β of the support surface 18. The angle is measured in relation to the axis of rotation 18. The angle is measured in with respect to the axis of rotation I of the capsule or an axis parallel I1 to this axis as illustrated in figure 14. As a result, all capsules in the set are self-locking in the capsule holder when inserted. Therefore, when the capsule is pressed by the interface assembly 13 during the closing of the preparation unit at margin 3, the body deforms slightly to assume its final rotational configuration in which all movements are adequately compensated. The angle α is preferably 1 to 5 degrees lower than the angle β of the support portion of the capsule support.
    [00062] The capsules in the set according to the invention contain roasted and beans coffee having preferably different roasting characteristics and / or grinding characteristics in the set.
    [00063] Coffee beans are generally roasted to form roasted coffee beans and then ground to produce roasted and ground coffee powder that is filled into the capsules. Any suitable process including roasting can be used. As used herein, the term "toasting" includes any heat treatment of coffee beans to create flavor that are indicative of coffee. Suitable roasting techniques may include, but are not limited to, oven roasting, extrusion roasting, steam roasting (eg, no further roasting), infrared roasting, microwave roasting,
    Petition 870200010656, of 23/01/2020, p. 20/33
    17/20 heat induction / dielectric roasting, and combinations of these. [00064] Coffee beans can be roasted to the desired color. The coffee beans can then be ground using any coffee grinder (for example: Probat or Matsubo grinders). Depending on the specific size of the desired particles in the final product of the present invention, the coffee fractions can be the distribution of volumes of ground particles or "grind volumes". For the determination of coffee granulometry, the particle size distribution (D4,3) and fine levels are typically determined by laser diffraction using the Malvern RTM Mastersizer S instrument.
    [00065] The system of the invention advantageously comprises means of identification ID1, ID2, ID3 (figures 4 and 5) or ID4, ID5 (figures 11 and 12) associated with each capsule to guarantee the control of the preparation parameters, in particular , the flow rate of the volume of the liquid injected into the capsule as a function of the volume of the capsule and / or the characteristics of the product (granulometry, roasting, etc.) and / or the drink to be produced (ristretto, espresso, lungo, coffee large, or extra large, etc.). The system of the invention is capable of providing different flow rates that are influenced by two key parameters: the rotational speed of the capsule in the device and the back pressure exerted on the centrifuged liquid. For a given back pressure, the higher the rotational speed, the greater the flow.
    [00066] On the contrary, for a given rotational speed, the greater the back pressure, the less the flow. Back pressure can be varied by varying the closing force of the flow restriction valve positioned downstream of the capsule closure and / or by varying the cross section of the restriction outlets, as described in the co-pending application patent PCT / EP08 / 066666. In the context of the invention, the term “flow rate” refers to the flow of the liquid, in particular
    Petition 870200010656, of 23/01/2020, p. 21/33
    18/20 water, injected into the capsule and which can be measured by any suitable means such as a metric flow meter and monitored by means of control.
    [00067] As is known, the rotational speed control is carried out by means of a selectively activated control of the rotational motor (not shown) that drives part of the interface of the assembly 13, the capsule support 14 and the capsule together in rotation. The volume control of liquid injected into the capsule is directed by means of control by selectively activating the pump 11 to measure the appropriate liquid volume.
    [00068] In particular, the means of identification can be to adjust different volumes of liquid injected for the distribution of different volumes of drink and / or to adjust the rotational speed of the device. In particular, for larger capsules in the set, the identification means can be larger capsules in the set, the identification means can adjust larger volumes of liquid than for smaller capsules. As well, the means of identification can also be adjusted at different flow rates for capsules smaller than larger capsules and / or different rotational speeds for capsules larger than larger capsules in order to provide different residence time of the liquid in the capsule. Preferably, the smaller the capsules or the smaller the drink (that is, or the volume of liquid injected into the capsule), the lower the flow rate. Finally, the identification means can also form different back pressure values in the capsule or outlet 29 where the flow restriction is positioned. Preferably, the volume of liquid injected, the rotational speed and the back pressure in the capsule are adjustable / adjusted by means of control (C) as a function of the volume. For example, the temperature of the injected liquid can be heated to a higher temperature to compensate for losses in liquid temperature in volumes
    Petition 870200010656, of 23/01/2020, p. 22/33
    19/20 bigger.
    [00069] As illustrated in figures 4 and 5, the identification means can be formed as selection means ID ', ID2, ID3 of a user interface 30. The selection means can be physical switches a or any other type of selectors such as in a touch screen multi-choice interface. Each selector corresponds to a certain type of beverage to be supplied, eg a particular type of coffee such as ristreto, espresso, lungo, etc., a particular volume of beverage (for example, 25, 40, 80, 110, 250 ml , etc.) and / or a particular selection of aroma, strength and / or foam / cream level. The user interface being connected to the control medium C, the production parameters are adjusted according to the selection made by the user of the selection medium for operation of the centrifugal production device.
    [00070] In an alternative illustrated in figures 11 and 12, the means of identification are directly associated with the different capsules. In this case, the identification meaning ID4, ID5 (or more) are capsules with recognition meaning attached to or embedded in the capsules. The meaning of identification for being either mechanical, optical, magnetic or radiofrequency recognition capable of providing information to the production device, through a sensor device 31, so that a capsule is inserted, through the sensor device 31, so that what kind of capsule is inserted into the device. For example, the recognition medium is a bar code, a color code, an RFID tag, a magnetic sensing element, or a mechanical or bypass key.
    [00071] The main benefit of controlling the adjustment of these different parameters is essentially coupled with the possibility of supplying a wide variety of drinks, especially coffee, of different volumes (for example, ristretto, espresso, lungo, americano, etc.), strength of aroma, strength and volume of foam / cream. The possibilities offered
    Petition 870200010656, of 23/01/2020, p. 23/33
    20/20 by the invention exceed traditional methods of preparation in which these parameters cannot all be adjusted together properly.
