    Field of Invention
    [001] The present invention relates to a capsule designed for the preparation of a beverage by centrifugation, the use of a capsule in a beverage production device and a capsule system that combines a capsule and a device for the production of beverage for preparing a beverage from a beverage substance contained in the capsule and passing a liquid fed by the device through the substance in the capsule using centrifugal forces.
    [002] In particular, the present invention relates to a capsule that forms, together with a device for producing beverages, a dedicated restriction valve, constituting a pressure adjustment device for the centrifuged liquid leaving the capsule. . Background of the Invention
    [003] There are systems for preparing beverages, such as coffee, by forcing the liquid through ingredients contained in the capsule using centrifugal forces.
    [004] WO 2008/148604, for example, refers to a capsule for preparing a drink or liquid food from a substance in a centrifugal preparation unit, passing water through the substance contained in the capsule using centrifugal preparation forces comprising: an enclosure containing a predetermined dose of substance; opening device, which opens under the centrifugal effect to allow the prepared liquid to leave the capsule. The capsule may also comprise device for engaging the capsule, external rotation drive device of a centrifugal preparation device, in which the engaging device is configured to offer a torque resistance during rotation of the capsule, to keep the capsule in a rotational position of reference.
    [005] With this the effect of centrifugal forces to prepare coffee, or prepare other food substances, presents several advantages compared to normal preparation methods using pressure pumps. For example, in traditional methods of preparing espresso or "lungo" coffee using a pressure pump, it is very difficult to master all the parameters that influence the quality of extraction of the distributed coffee extract. These parameters are typically pressure, flow rate which decreases with pressure, compaction of the coffee powder which also influences the flow characteristics, and which depends on the ground coffee particle size, temperature, water flow distribution, and so on. Therefore, it is not easy to vary the extraction pressure and flow rates, as they are essentially determined by the resistance of the coffee bed and the downstream filtration system.
    [006] For a centrifugal extraction, the quality of the beverage to be prepared (intensity or strength, flavor, foam/cream aroma, etc.) is complex, and depends on the control of different preparation parameters and capsule design. In particular, the flow rate of liquid injected into the capsule seems to play an important role. The flow rate can be influenced by numerous parameters, such as the speed of rotation of the capsule in the device, the dynamics of the fluid inside the capsule, the back pressure exerted on the centrifuged liquid. For example, given a back pressure, the greater the rotation speed, the greater the flow. Conversely, for a given rotational speed, the higher the back pressure, the lower the flow. While the speed of rotation of the capsule is usually controlled by a control device that selectively activates a rotation motor of a centrifugal beverage production device, a pre-defined back pressure can be obtained by restricting flow at the outlet of the capsule or on the outside of a centrifugal cell that carries the capsule.
    [007] For example, EP 651963 teaches that a pressure gradient is obtained by an elastic-rubber element interposed at the interface between the engagement lid and the centrifugal cell cup, for example, a capsule containing coffee powder. Such an element elastically deforms to leave a filtration passage for the liquid when a certain pressure is reached at the interface.
    [008] Furthermore, documents FR 2,487,661 and WO 2006/112,691 relate to centrifugal systems where a fixed restriction is placed downstream of the filter to create a pressure gradient.
    [009] Furthermore, WO 2008/148646 proposes a solution in which a flow restriction is placed in or outside the centrifugal cell. The flow restriction may comprise a regulating valve which provides an effective pressure. The valve opens under the effect of pressure. The more the valve opens, the greater the flow. The valve can be preloaded by a resilient element (rubber or spring). The larger the precharge, the higher the opening pressure for the centrifuged liquid upstream of the valve.
    [010] EP 1,654,966 A1 relates to a capsule with sealing device, which comprises a base body with a rim as a flange and a sheet element that closes the body. Such a capsule is not designed to be used in a centrifugal preparation device.
    [011] The prior art centrifugal beverage production system, however, suffers from the disadvantage that an adaptation of the backpressure to preset values requires a mechanism that makes it complex to adjust to a wide variety of different predefined backpressure values.
    [012] With this, it should be understood that in particular in relation to coffee beverages, the back pressure applied in the centrifuged liquid determines the extraction conditions (for example, flow) thereby directly influencing the flavor and/or aroma of the coffee. Furthermore, the organoleptic texture such as the foam/cream formed on top of the prepared beverage, also highly depends on the applied back pressure. Thus, with regard to the foam/cream, as well as the flow rate of a coffee beverage to be prepared, it is desired to adjust the back pressure values depending on the nature of the substance supplied in a specific capsule, as for different types of beverages, a quality and /or different amount of foam/cream respectively a different flow rate is desired.
    [013] Therefore, there is a need to propose, through a capsule system, coffee varieties with different flavors, intensities and/or types, for example, "ristretto", espresso, "lungo", long coffee, etc. ., in particular, whereby the back pressure exerted on the centrifuged liquid at the interface between the capsule and the device can be controlled better, more independently and more conveniently.
    [014] The term "valve device back pressure" refers to the pressure loss created by the restriction or restriction valve. Since the restriction or restriction valve forms a bottleneck effect, a liquid pressure is created upstream of it by the effect of centrifugation. In particular, a pressure gradient is created, in which pressure gradually increases from the axis of rotation towards the valve. Thanks to this restriction the pressure before the restriction is increased, and it is this pressure that has an effect on the liquid-ingredient interaction, for example, by means of extraction of the substance by the liquid. This pressure created by the restriction valve can also be defined as the ratio of force ("counterforce") divided by the contact surface area at the restriction valve.
    [015] European Patent Application also pending number 08171069.1(titled "Capsule for preparing a beverage by centrifugation in a beverage production device and device adapted therefore" ("Capsule for preparing a beverage by centrifugation in a beverage production device" and device adapted for this") proposes a capsule in which a force ring is provided, which is engaged by a pressing surface of the beverage production device, to form a valve device that delivers, under the force of resilient device associated with the pressing surface and depending on the height or thickness of the force ring, a certain back pressure during beverage extraction.
    [016] It has now been discovered that the design of the force ring in the capsule impacts the quality of the coffee in the cup, in particular the aroma content of the coffee extract.
    [017] An objective of the present invention is to propose a capsule designed for centrifugal extraction that further improves the quality of the cup beverage, in particular coffee. The proposed solution is also easy to form, economical, and can be reliably produced in mass production with high respect for dimensional tolerances.
    [018] In addition, the proposed solution makes it possible to provide, in an easy and economical way, different back pressures in the device, for example, to provide a wide range of beverages, for example, coffee drinks. In addition, the proposed solution also allows the possible use of materials that provide high gas barrier properties, for example aluminum, thereby avoiding the need for an expensive overcoating package.
    [019] The present invention provides a solution to the aforementioned problems, as well as offers additional benefits to the existing technique. Purpose and Summary of the Invention
    [020] The present invention relates to a capsule designed for insertion into a beverage production device, to prepare a beverage from a substance contained in the capsule, introducing liquid into the capsule and passing liquid through the substance using centrifugal forces ,
    [021] The capsule comprising: a body comprising a bottom end and an open end, spaced apart in the axial direction, a top wall for covering the body at its open end along a direction transverse to the axial direction, a the enclosure between the body and the top wall, which contains a quantity of beverage substance, the capsule comprising a rim as a flange extending outwardly from the body, in which the rim as a flange comprises an annular flange portion; wherein the capsule comprises an annular pressure adjusting ring configured to be engaged by a valve member of the beverage production device to provide a flow restriction valve for the flow of centrifuged beverage leaving the capsule; wherein the annular pressure adjusting ring extends transversely and axially beyond the flange portion.
    [022] The pressure adjustment ring is more particularly designed to adjust the back pressure formed by the valve device when inserted into the beverage production device.
    [023] More particularly, the annular pressure adjusting ring extends in the axial direction of the capsule above the plane of the annular flange portion to be engaged by a valve element of a dedicated beverage production device, and extends in the direction of the capsule below the plane of the flange portion to be accommodated in a lowered annular portion or recess of the capsule holder of the production device.
    [024] The annular pressure adjustment ring (also called the "power ring"), forms, in combination with a dedicated compression surface of a valve element of the beverage production device, a restricting valve for the beverage flow out of the capsule during centrifugation. The pressure adjustment ring is more particularly configured, together with the device's dedicated compression surface, to selectively block the flow path of the centrifuged liquid to delay the release of liquid from the capsule and to adjust the liquid flow rate. as a function of rotational speed. More particularly, when a sufficient pressure of the centrifuged liquid is reached in the valve device, i.e. the centrifuged liquid which forces against the pressure adjusting ring, the valve device opens, i.e. a restricted flow is provided by a surface of compression device that moves away from the pressure adjustment ring of the capsule, or vice versa. Before the pressure of the centrifuged liquid is reached, the valve device remains closed. Hence, the pressure adjustment ring in engagement with the pressing surface blocks the flow path for the centrifuged liquid. It should be noted that the opening of the valve device depends on the rotation speed of the provided driving device, which drives the capsule in rotation in the beverage production device. Therefore, since the valve device selectively blocks the flow path for the centrifuged liquid, a preliminary wetting step of the beverage substance, e.g. ground coffee, can be carried out, since no liquid is yet discharged of the device. As a result of a pre-wetting and delayed release of the beverage, a wetting through the entire substance is made possible, and the interaction time between the liquid and the beverage substance, eg coffee powder, substantially increases, and the extraction characteristics, eg coffee solids content and beverage production, can be significantly improved.
    [025] More particularly for a capsule of the invention, the annular pressure adjusting ring of the capsule extends in the axial direction of the capsule above the plane of the annular flange portion, for a distance longer than the distance it extends in the axial direction of the capsule below the plane of the flange portion.
    [026] In one mode, the annular pressure adjustment ring of the capsule is hollow. More preferably, the pressure adjusting ring is formed as an annular curl. By curl or curl end is meant a substantially curled portion of material, for example a curled fold which forms a relief portion at the free end of the ring as a flange of the cap. The material curl can be partially or completely wound. Snail winding can be achieved by different techniques such as forming, embossing, deep drawing, etc. More preferably, the curl is rolled to form a substantially closed hollow curl. Such a feature provides the advantages of maintaining a relatively light structure while providing sufficient resistance to deformation of the ring in the axial direction when it is pressed by the valve element. Furthermore, it makes it possible to use packaging materials in the form of a sheet, such as by deep stretching, pressing or shaping.
    [027] In a particular mode, the annular pressure adjustment ring forms an oval auger whose longer dimension extends substantially in the axial direction. This feature provides a higher resistance to ring deformation without increasing the material thickness.
    [028] In another particular mode, the annular pressure adjustment ring forms an oval curl whose longer dimension extends substantially in the transverse direction.
    [029] However, in other modes of capsules the annular pressure adjusting ring forms a relatively round auger, in particular when the distance of the annular pressure adjusting ring above the plane of the annular flange portion remains relatively short.
    [030] In particular, the annular pressure adjustment ring can be made of plastic and/or metal. More preferably it is made of aluminum or a multi-layer of aluminum and plastic, preferably aluminum-PP (polypropylene) laminate. "Aluminium" herein encompasses any aluminum-based alloy or composite. Preferably the pressure adjusting ring is formed in one piece with the flange and body portion of the capsule.
    [031] The capsule can be a closed capsule in which the top wall is a pierceable membrane that closes the body of the capsule. More preferably, the capsule is closed in a gas-tight manner to ensure longer shelf life of the capsule. For this the packaging materials will be chosen to provide gas barrier properties on all sides of the capsule. The capsule can furthermore be filled with a gas that protects the substance from oxidation, such as nitrogen, or a mixture of carbon dioxide and nitrogen. In another possible mode, the capsule is not completely closed, but comprises an upper wall with pores or openings that allow liquid to be fed in and/or extracted out. Pores or openings in the top wall are preferably provided at the periphery of the top wall. The pores or openings are preferably distributed peripherally along a substantially circular path and a short distance from the flange portion, such as between 0.5 to 10 mm, preferably between 1 and 8 mm.
    [032] In another mode the annular pressure adjustment ring is full. By "full" is meant here that the pressure adjustment ring is not hollow but filled with the same or a different material. The pressure-adjusting ring can, for example, be provided with an increase in the thickness of the rim as a flange, which protrudes both above and below its flange plane. For example, the increase in material thickness forms a portion that is integrated with the rest of the rim as a flange. In another example, the annular flange portion is made of flexible film portion to which an annular portion of solid solid material, eg hard plastic or rubber, is sealed.
    [033] In a preferred mode, the ratio of the distance of the pressure adjusting ring above the plane of the flange portion to the distance of the ring below the plane of the flange portion is comprised between 5:1 and 1:0.5. In particular, the distance above the plane of the flange portion is preferably comprised between 0.5 and 3 mm, preferably 0.8 and 2.5 mm. Furthermore, the distance below the plane of the flange portion preferably comprised between 0.1 to 2 mm, preferably 0.1 is 1 mm, more preferably 0.3 and 0.5 mm.
    [034] In a possible mode, the pressure adjustment ring only extends axially above the plane of the flange portion of the rim, but is free of any axial extension below said plane. In such a case it is also preferred that the rim as flange is deformed at least at the junction between the flange portion and the pressure adjusting ring when a pressure from the valve element is applied over the ring to ensure a proper fit of the cap in the device. - positive, and correct adjustment of the back pressure. For example, the deformability of the rim as a flange is achieved by at least a local portion of reduced thickness of the flange portion and/or by a sufficiently small thickness, for example, such as a local portion or thickness that is lower than 0.8 mm for plastic material or other polymers, and lower than 0.4 mm for aluminium.
    [035] Furthermore, the capsule of the invention is specifically sized to provide sufficiently high centrifugal forces or pressures on the pressure adjustment ring. For this, the radial distance from the central axis (I) of the capsule to the pressure adjustment ring. More preferably such distance is comprised between 24 and 31 mm. More preferably, such distance is comprised between 25 and 30 mm. It has surprisingly been found that above the upper limit a significant loss of coffee aroma can be perceived irrespective of the speed of rotation of the capsule in the device. Such loss is representative of less good coffee extraction conditions at such value. Below the lower limit, due to the lower centrifugal forces exerted on the force ring, flow becomes very low and extraction conditions are also impacted. Therefore, a radius above the given lower limit makes it possible to maintain relatively moderate rotational speeds while maintaining sufficient pressure and flow in the force ring. In addition, a shorter radius would require an increase in pod depth to maintain a pod size that allows the same amount of coffee powder to be stored. This should likely lead to lower extraction homogeneity, with areas of coffee powder less wet than others. As will be described further, the radius is here measured as the distance from a central axis of the capsule to the top point of the force ring, which represents the distance (hereinafter referred to as h1) from the above pressure adjustment ring. of the plane (hereinafter referred to P) of the flange portion of the rim.
    [036] The present invention further relates to a capsule designed for insertion into a beverage production device to prepare a beverage from a substance contained in the capsule, introducing liquid into the capsule and passing liquid through the substance using centrifugal forces,
    [037] The capsule comprising: a body comprising a bottom end and an open end, spaced apart in the axial direction, a top wall for covering the body at its open end along a direction transverse to the axial direction, an enclosure between the body and the top wall, which contains a predetermined amount of beverage substance, the capsule comprising a rim as a flange extending outwardly from the body, wherein the rim as a flange comprises an annular flange portion of a ring of annular pressure adjustment extending from said annular flange portion; in which the annular pressure adjustment ring forms a wound arc of the rim as a flange.
    [038] The present invention, furthermore, is related to a set of capsules comprising at least two capsules of different type; preferably at least three capsules of different type, each capsule being configured in accordance with the aforementioned capsule, in which the distance in the axial direction above the plane of the annular force ring differs as a function of the type of capsules.
    [039] As a result of the difference of said distance in the axial direction, different values of back pressure are adjusted by the pressure adjustment ring of the capsule when the capsule is engaged in the beverage production device, with this contributing to change the characteristics of the centrifuged beverage. In particular, when the distance above the plane of the annular pressure adjusting ring increases, the preload on the valve device is increased thereby increasing the pressure in the capsule and the residence time of the liquid in the capsule for a given velocity of rotation.
    [040] The expression "type of capsules" here refers to capsules that have at least one difference that characterizes different beverages, for example, coffee beverages, capable of distributing different key beverage attributes (flavor, intensity, cream /foam, flow time, etc.), such difference being characterized by any of the following parameters: capsule size, substance amount, substance density, eg condensed density), specific composition (eg mixture, origins of coffee), grinding size, filling level and their combinations. The term "capsule size" means in particular the storage volume of the capsule potentially available to accommodate the substance and/or the outer volume of the capsule, for example your body.
    [041] The term "set of capsules" means a series of at least two, three, four, five, six or more capsules of different types.
    [042] Preferably the distance in the axial direction below plane P of the flange portion of the annular pressure adjustment ring is constant throughout the entire assembly. Therefore, this distance serves as a reference for all capsules in the set, thereby ensuring that each capsule is correctly positioned in the device, and the pressure adjustment ring does not flex or deform significantly, as such deflection or deformation could impact the accuracy of the backpressure adjustment.
    [043] The present invention further relates to a system for preparing a drink, which comprises a capsule as mentioned above, and/or a set of capsules as mentioned above a device for the production of drink by introducing liquid into the capsule and passing liquid through of the substance using centrifugal forces,
    [044] The beverage production device comprising: a capsule holder to support the capsule at least on the rim as a flange, during centrifugation, rotation drive device to drive the capsule in centrifugation, a liquid injection element to feed liquid in the capsule, a spring-loaded valve element for engaging the pressure adjusting ring of the capsule and/or a capsule of the assembly, when the capsule is inserted into the beverage production device, to provide a flow restricting valve.
    [045] The invention is also related to the beverage production device as such.
    [046] The invention further relates to the use of a capsule as mentioned above in a centrifugal device for beverage production, in which the capsule is centrifuged in the device and the annular force ring is engaged by an enveloping element of the device dedicated to beverage production, such a force ring being part of a valve device for selectively blocking, and/or restricting, the flow of centrifugal liquid leaving the capsule.
    [047] More particularly the capsule holder comprises an annular transverse support edge comprising a first inward portion to support the annular flange portion and a second outwardly portion to support the annular pressure adjustment ring, in the which the second outward portion forms a lowered step, or recess, as compared to the first inward portion.
    [048] In a preferred mode, the device for producing a beverage further comprises a control device configured to control the liquid flow rate and/or the rotation speed of the drive device as a function of the type of capsule inserted in the device . In particular, control of liquid flow and/or rotation speed can be performed by keeping at least one of these parameters (ie, flow and/or rotation speed) constant, or varying it according to a predefined evolution profile (for example, rotation speed curve) or by dynamically adjusting said parameter as a function of the variation of another parameter, for example, the second of these parameters. In a particular mode, the liquid flow is kept constant, at least for a period of time during extraction, by varying the speed of rotation during the extraction process.
    [049] The invention is also related to the use of the capsule as mentioned above in such a device to dispense a drink.
    [050] The invention can also be related to a capsule kit designed to be filled with a beverage substance, and insertion into a beverage production device for preparing a beverage by introducing liquid into the capsule and passing liquid through the substance using forces centrifuges. The cap kit can comprise all the features of the cap as described in the present description, in particular the pressure adjusting ring. The capsule kit further comprises connecting device that enables connection of the top wall onto the capsule body, such connecting device being configured to fix the top wall to the body after filling the capsule with beverage substance. The connecting device can be a snap-fit arrangement, a thread, an adhesive, and a combination thereof. The connecting device is preferably designed in such a way that a user is able to connect the top wall to the body of the capsule, without necessarily using tools. Brief Description of Drawings

Figure 13 is an enlarged cross-sectional view of a detail of the capsule of Figure 12. Detailed Description of Drawings
    [053] Figures 1, 3 and 5, respectively, figures 2, 4 and 6 in order of stacking for detail, are related to a preferred embodiment of a set of capsules 1A, 1B, 1C according to the invention. Each capsule is for single use only, and is designed to dispense a beverage from a beverage production device. The capsule preferably comprises a cup-shaped body 2 and a ring-like circular annular flange 3 and a disc-shaped top wall element, preferably a pierceable membrane 4. The cup-shaped body 2 may be gourd-shaped as illustrated, or other ways. With this the membrane 4 and the body 2 enclose an enclosure, respectively ingredient compartment 6. As shown in the figures, the membrane 4 is preferably connected over an inner annular flange portion 7 of the rim 3, which is preferably between 1 to 5 mm . The membrane 4 is connected to the body rim 3 by a seal such as a thermal or ultrasonic welding line.
    [054] The rim is not necessarily horizontal as illustrated. It can be bent slightly, up or down, to increase the strength of the seal to the increasing pressure it pushes on the membrane over time, due to the degassing of the capsule substance or ingredient over time.
    [055] The rim 3 of the capsules preferably extends outward in an essentially perpendicular direction as illustrated, or slightly slanted (if bent as mentioned above) with respect to the central axis of symmetry I of the body which corresponds to the axis of rotation Z of the capsule 1 in the beverage production device (see figure 7). Generally speaking, axis I also represents the center around which the rim as an annular flange 3 extends in an annular configuration. With this the axis of symmetry I is aligned with the axis of rotation Z during centrifugation of the capsule in the preparation device. For example, a slight tilt represents an angle of between approximately 1 and 30° from the central axis of symmetry.
    [056] It should be understood that the shown cup-shaped embodiment of the capsule is only one embodiment taken as an example and that the capsule, in particular the capsule body 2 according to the invention, can take on several different shapes.
    [057] Capsules 1A, 1B, 1C are preferably single use capsules. However, it should be noted that the capsules can dispense more than one drink at a time, for example a volume of coffee extract sufficient to fill two cups at the same time.
    [058] The body 2 of the respective capsules 1A, 1B, 1C has a convex portion 5a, 5b, 5c of variable depth, respectively d1, d2, d3. However, portion 5a, 5b, 5c may also be a truncated or cylindrical portion or a combination of differently shaped portions such as truncated, cylindrical, spherical, etc.
    [059] Hence, capsules 1A, 1B, 1C preferably comprise different storage volumes of ingredient, but the same insert diameter "D". Figure 1 shows a small volume capsule 1A while figure 3 shows a medium volume capsule 1B, figure 5 shows a large volume capsule 1C. The insert diameter D is hereby determined at the line of intersection between the lower surface of the rim 3 and the surface of the side wall of the body 2. However, it could be another reference diameter of the capsule in the device.
    [060] The capsules of the invention 1A, 1B, 1C are also specifically sized to provide optimized flow rates in the pressure adjustment ring 8 when the capsule is centrifuged in the beverage production device, as will be explained later. For this, the radius R representing the distance between axis I and the distance h1 above plane P is preferably comprised between 24 and 31 mm. More preferably this radius is comprised between 25 and 30 mm, even more preferably approximately 28 ± 1 mm. If the radius is too low, the flow rate decreases significantly at the same closing pressure in the ring. To compensate for such low flow, it is necessary to increase the rotation speed, but this negatively influences other factors, such as noise cost and system cost. On the other hand, too high a radius also negatively impacts stability during the system's centrifugation process, and creates a very bulky capsule in the device.
    [061] In addition, the larger inner diameter of the capsule enclosure when measured at the junction between the rim portion as flange 7 and the body 2 just below the top wall 4 is preferably comprised between 45 and 50 mm. These threshold values are also preferred to ensure a sufficient width of the exit area on the top wall of the capsule. The lower the value, the lower the pressure on the upper periphery of the enclosure at a given rotational speed. Above the upper limit it would no longer be possible to position the force ring effectively.
    [062] The body 2 of the capsules is preferably rigid or semi-rigid. It can be formed from a food grade plastic, for example polypropylene with a gas barrier layer such as EVOH and the like, or aluminum, or a plastic and aluminum laminate such as aluminium-PP (polypropylene) laminate in which preferably PP forms the inner layer of the laminate and aluminum forms the outer layer of the laminate. Additional boards or colored layers can be provided. The membrane can also be formed from paper and plastic, paper and aluminum, or a combination of paper, aluminum and plastic. Plastic also includes biodegradable plastics such as crystallized PLA, or equivalent. The membrane 4 can be made of a thinner material such as a plastic film that also includes a barrier layer, or aluminum, or a combination of plastic and aluminum. Membrane 4 is usually of a thickness between 10 and 250 microns, for example. The membrane is perforated to create water ingress as will be explained later in the description. The membrane also further comprises a pierceable peripheral area.
    [063] Instead of the membrane 4, the capsules 1A, 1B, 1C may also comprise rigid, semi-rigid or flexible engagement lid element, which preferably is in the form of a disk comprising a central portion having a port of inlet to enable the introduction of a water injection element, and peripheral portion having circumferentially arranged outlet openings.
    [064] For example, the outlet openings can be formed by an annular layer of filter paper and/or plastic fabric. The inlet port and/or outlet openings are hereby prefabricated before inserting the capsule into the device. They can be covered by a removable gas-tight layer prior to insertion, such as an overlay pack or a peelable membrane.
    [065] The volume difference between the small and large capsules is obtained, in particular, by varying the depth d1, d2, d3 of the body 2 of the capsules in the set. In particular, the depth of the smaller capsule body 1A is lower than the depth of the medium sized capsule body 1B and the depth of the medium sized capsule body is lower than the depth of the larger sized capsule body 1C.
    [066] More generally, an internal volume of the capsule is preferably comprised of 18 ml and 50 ml. These volumes have been determined to provide at the same time enough space to accommodate a sufficient amount of coffee powder, while providing optimized centrifugal extraction (coffee) conditions.
    [067] Another variant should also consist of having only capsules of the maximum size (figure 5) and different filling levels of substance accommodated in the compartments, depending on the type of drink to be produced, for example, "ristretto", espresso, "lun - go", long coffee, "dried coffee", tea, chocolate, etc.
    [068] Capsules are filled with beverage substance depending on their size. Such size can be determined, as mentioned above, preferably by varying the depth of the capsule d1, d2, d3. Therefore, the smaller volume capsule 1A contains an amount of substance for extraction, eg ground coffee, less than the amount for the medium volume capsule 1B, and the medium volume capsule contains an amount of substance for extraction, per example, ground coffee, less than the amount for the 1C maximum size capsule.
    [069] Hence, the small capsule 1A is preferably designed to dispense a shorter coffee beverage of between 10 ml and 60 ml with an amount of ground coffee comprised between 4 and 8 g. The larger capsule 1B is designed for dispensing a medium sized coffee, for example between 60 and 120 ml and the maximum capsule 1C is designed for dispensing a large size coffee, for example between 120 and 500 ml. Furthermore, the medium size coffee capsule 1B can contain an amount of ground coffee comprised between 6 and 15 g, and the long size coffee capsule 1C can contain an amount of ground coffee between 8 and 30 g. The filling level of substance in the capsules can also be adjusted to ensure a well-distributed flow of liquid into the ingredients without creating preferred liquid path due to centrifugal forces in the capsules. In general the substance should not be filled to create a compact cake or be filled to the top of the capsule in a compact manner prior to use (ie, centrifugation of the capsule in the device).
    [070] Preferably the capsules in the set according to the invention may contain different mixtures of roasted and ground coffee, or coffees of different origins and/or having different roasting and/or grinding characteristics. The average particle size (D4,3) of roast and ground coffee contained in the capsule can be comprised between 120 and 750 microns, preferably between 160 and 500 microns.
    [071] In general the substance may include roast and ground coffee, instant coffee, cream formers, (dairy or non-dairy), tea (grey, green, white or herbal), cocoa, chicory, infant formula, and combinations thereof. Additives can also be added, such as sweeteners, sugar, aspartame, stevia, etc.), flavorings (cinnamon, vanilla, herbs, etc.), processing aids, emulsifiers, foam strengtheners, fruit or plant extracts, micronutrients and combinations their.
    [072] The capsules of the invention, as illustrated in figures 2, 4 or 6, more particularly comprise in their rim as flange 3, an annular pressure adjustment ring 8 protruding at the same time upwards and downwards from the inward flange portion 7. In particular, the pressure adjusting ring, the function of which will be explained later, comprises an upper portion 9 extending in the axial direction of the capsule above a plane P passing through the flange portion 7 and a lower portion 10 which extends below plane P still in the axial direction of the capsule. By convention, reference to plane P is here taken along the lower surface of flange portion 7. In the context of the invention, the term "axial direction" refers to any direction aligned or parallel to the central axis I of the capsule. The term "transverse direction" refers to any direction perpendicular to the central axis I or inclined by an angle greater than 45°. The term "lower" and "upper" here refers to the relative positions of the devices as illustrated when the top wall 4 of the capsule is oriented upwards and the bottom of the body 2 downwards. More preferably the upper portion 9 of the ring extends over a distance h1 which is longer than the distance h2 of the lower portion 10. In particular, the distance h1 determines the axial length of the pressure adjusting ring in the capsule assembly. For this the distance h1 varies in the set while the distance h2 remains constant in the set. Therefore, for example, the minimum cap 1A is provided with a pressure adjusting ring 8 which extends above plane P by a distance h1 which is greater than the distance h1 of the force ring above the plane P of the size cap medium 1B. Comparatively, the distance h1 of the pressure adjusting ring of the medium-sized capsule 1B is also greater than the distance h1 of the full-size capsule 1C. With this the distance h1 preferably decreases with increasing capsule size, for example, as depth (d1, d2, d3 ) increases as a whole. This will result in adjusting different back pressure values in the beverage production device, as will be explained later, to adapt to the preparation characteristics of such capsules, in particular to their size and coffee powder content. With this the thickness h1 of the pressure adjusting ring 8 is preferably adapted to the type of capsule, more particularly to the quantity and/or characteristics of the beverage substance contained in the capsules shown 1A, 1B and 1C to enable an adjustment of the back pressure exerted on the capsule when being inserted into the beverage production device. For example, for capsules containing a small amount of beverage substance, eg capsule 1A for preparing eg a "ristretto" or espresso coffee beverage, a high pressure extraction might be desired to supply the coffee with a high intensity (ie a large amount of total coffee solids transferred in coffee extraction) and a thick cream. These characteristics can be compared to a lower pressure extraction pressure that might be desired for beverage coming out of capsule 1B or 1C that contains a greater amount of coffee powder. Therefore, for a given rotational speed during beverage extraction, back pressure of a smaller volume capsule 1A containing a smaller amount of substance is adapted to be higher than the back pressure of the larger capsule 1B or 1C containing a more amount high of substance. Of course, the speed of rotation can also vary depending on the type of capsules 1A, 1B, 1C and the beverage to be produced.
    [073] In a preferred mode of the invention, the pressure-adjusting ring 8 of the capsule is formed by a curled edge or curl of the rim as a flange, thereby forming a curl which can be closed or partially closed. In particular, the curl can be formed from a ply of material by any forming technique, such as embossing, stamping, molding, etc. Preferably the upper portion 9 forms an intermediate portion as a ply of material between the flange portion 7 of the rim and the portion 10. The lower portion 10 may extend over a recessed portion 11 of the ply forming the end portion of the curl. It should be noted that the upper portion 9 can be convex in the axial direction as illustrated, however other shapes are possible, such as flat or concave. Similarly, the lower end of the lower portion 10 may be convex in the axial direction as illustrated, but other shapes are possible, such as flat or concave. Furthermore, the pressure-adjusting ring is preferably hollow in shape when shaped like a curl as shown, however a full ring, i.e. not hollow, is also provided as a possible alternative. For example, the ring can be formed as a curl and filled with material such as plastic or rubber to improve its resistance to deformation in the axial direction.
    [074] For capsules 1A, 1B, the pressure adjustment ring can be oval shaped in the axial direction since the height "h" of the ring that corresponds to the sum of the distance h1 and the distance to h2 is greater than the width w from the ring. For capsule 1C the width w can be equal by making the curl substantially round or slightly longer than height h of the ring, thereby making the ring an oval curl in the transverse direction.
    [075] As illustrated in figures 2, 4 and 5, the pressure adjustment ring 8 also fulfills the function of maintaining a distance between the bodies of capsules when stacked on each other. Therefore, this facilitates the unstacking of the capsule bodies during storage, in particular during manufacture, for example, before the bodies are filled with the beverage substance. As shown in Figures 2, for example, when the stacked bodies meet by contact between the lower portion 10 on the upper portion 8 of the pressure adjustment ring, the distance h1, h2 of the respective portions 9, 10 ensures that the portions of flanges 7 remain distant (see distance h3) from one another and do not come into direct contact with each other. Such a configuration greatly facilitates the unstacking of the bodies, and with this makes it possible to manufacture the capsule bodies in a manufacturing area that is remote from the capsule manufacturing location (coffee handling, filling, sealing, etc.).
    [076] Figure 7 shows a side view in section of a device for producing beverage according to the capsule system of the invention, in a closed state. With this, the device comprises the rotating capsule holder 20, a drive device 21, and a collector 22, onto which the centrifuged liquid impacts and drains through a beverage outlet 23. The drive device 21 comprises a rotary motor which is hinged to the capsule holder 20 on the bottom side (as illustrated) or top side (not illustrated) via an axle 24 axially connected to the capsule holder. The capsule holder 20 has a circumferential surface which forms a reference diameter substantially equal to the diameter "D" of the capsule 1 so as to ensure a tight fit of the capsule on the capsule holder 20, without possible radial play. Capsule holder 10 is preferably hollow or deep enough at its center to be able to accommodate all the caps in the set. Consequently, a single capsule holder is sufficient to accommodate all the capsules 1A, 1B, 1C of the set. It should be noted that the capsule holder can take various shapes and can also be formed from a simple hollow annular ring.
    [077] Furthermore, the device comprises water injection device 25 which has an injection element 26 which is arranged to perforate the membrane 4 of the capsule 1 in a central portion thereof. As already described in WO 2008/148604 the injection device 26 is connected to a liquid circuit 28 comprising a liquid supply 29 such as a water tank, a pump 30 and a liquid heating apparatus 31 to supply a volume Preset of heated pressurized liquid for capsule 1 during the beverage extraction process. Liquid is usually room heated or cooled water. Liquid is fed into the capsule by means of injection through the injection element 26 which is in the form of a hollow needle or tube. The injection element can be formed with a sharp free end to ensure perforation of the top wall if necessary. The device also comprises a series of output punches 27 as described in WO 2008/148604. Output perforations are provided on the periphery of the engagement cap 33 which engages the top wall of the capsule during closing of the device. Consequently, outlets are produced in an annular portion of the membrane 4, with this enabling a centrifuged extracted beverage to leave the capsule 1 during its rotational movement.
    [078] The device further comprises a control unit 40 that controls the different elements of the device, in particular the pump 30, heater 31 and the rotation speed of the drive device 21. In particular, the control unit is programmed to adjust operating parameters during extraction, which include, but are not limited to: pump flow rate, pump pressure, water temperature, rotational speed, rotational speed cycles, for example, speeds during pre-wetting, extraction, drying phases, etc. Several programs can be specifically designed for the different types of capsules 1A, 1B, 1C, for example, dispensing specific drinks, eg "ristretto", espresso, "lungo", American, etc., and/or drinks that have resistance specific, flavor profiles, foam/cream volume, etc. Capsules may comprise an identification code such as a bar code, radio frequency tag, etc., to enable identification in the device for automatic adjustment of operating parameters. In this case, the device comprises suitable code reading device associated with the control unit. The control device and code can be configured to ensure a key preparation parameter control, such as any or any combination of the following parameters: liquid volume (small, medium, long, extra long, cups, etc.), velocity drive device rotation, liquid pump speed, or speed cycle (eg slow speed for pre-wetting, high speeds for extraction and drying), liquid heating temperature, etc.
    [079] The system of the invention comprises a valve device 18 capable of providing a back pressure against the centrifuged liquid that leaves the capsule through its perforated or pre-made outlets. The valve device 18 is formed by the complementary engagement of the device in the capsule. More particularly (figure 9) the device comprises a valve element 34 which is arranged circumferentially with respect to the engagement cap 33 and which has a lower annular pressing surface 35. On the side of the capsule, the valve device comprises the adjustment ring pressure 8 which is engaged by means of the annular pressing surface 35 of the valve element 34 of the device. Compression surface 35 engages the upper portion of the pressure adjusting ring about a predetermined back pressure. The pressure engagement of the two complementary portions 34, 8 of the valve device is made resilient by means of an elastic displacement device such as spring 36 placed between the valve element 34 and an annular counterforce element 37 connected directly or indirectly to or part of the engagement cover 33. Several springs 36, for example 6 to 10 springs, may also be placed at the periphery between the portion 34 and the element 37, such as coil springs in parallel to distribute and balance the preload on the Capsule rim also. Naturally other equivalent resilient devices to replace the springs can be provided without departing from the scope of the invention.
    [080] The valve element 34 and the injection unit 25 are typically movable relative to the capsule holder 20, or vice versa, through a closing system (not shown) to enable insertion and injection of the capsule 1 to and from the capsule holder 20 before and respectively after the beverage extraction process. The closing system can be a mechanical and/or hydraulic closing mechanism. Various mechanical closure mechanisms are shown for coffee machines such as levers that form a knee joint or cam-type closure, and the like. Furthermore, the water injection device 25, the valve element 34, the capsule 1 and the capsule holder 20 are all rotatable about axis Z during the centrifugation process. The valve element 30 is also made movable independently of the engagement cap 33 to take into account the possible different thicknesses of the capsules without affecting the relative position of the injection portion when engaging the capsule. For this, the portion 34 can be slidably mounted around the engagement cap 33. A gasket 34 such as an O-ring can be provided between the two parts 33, 34 to ensure liquid tightness of the device. valve.
    [081] On the side of the capsule holder, the pressure adjustment ring 8 is firmly supported by a lowered portion or recess 38 of the supporting edge of the capsule holder 20. The lowered portion, or recess 38, is lowered at relation to a flange support portion 39 of the edge of the capsule support which supports the flange portion 7 of the rim. The height of the step between the lowered portion 38 and the support portion is preferably equal to or close to the distance h2 to ensure a correct fit between the capsule and the capsule holder, and firm support of the ring 8 by means of the capsule holder. However, it could also be that the distance h2 of the ring is less than the height of the step, thereby causing the force ring to be bent relative to the flange portion 7 under pressure from the valve element 34. flange 7 can be further compressed by a peripheral portion 40 of the engagement cap 33. The peripheral portion 40 comprises radially oriented channels or recesses 41 to ensure that the centrifuged liquid leaving the outlets pierced by the piercing device 27 can pass through the engagement cap on its way to the valve device 18. It is possible that the flange portion 7 has a shape or line of curvature, for example, slightly concave, convex or slanted, which differs slightly from the profile of the flange support surface 39. In this case, the flange portion 7 may be further deformed by the peripheral portion 40 of the engagement cap 33, for example being flattened against the support surface 39 to ensure tight fit. that of the force ring in the recess or lowered step 39.
    [082] Therefore, the back pressure of the valve device is essentially predetermined by the pressure adjustment ring 8 which changes the relative position of the valve element 34 and the compression of the elastic displacement device 36. Depending on the type of capsules, for example , caps 1A, 1B, 1C placed in the device, the back pressure varies as a result of different geometries of the pressure adjusting ring 8. Cap 1A of figure 9 has a shorter ring 8 compared to cap 1C of figure 11. In particular, as already mentioned, distance h1 is comparatively lower for capsule 1A while distance h2 is the same for all capsules 1A-1C. As a result, the elastic displacement device 36 becomes less pre-compressed when the capsule 1A is engaged with the device, than when the capsules 1A, 1B, 1C are engaged. Since the elastic displacement device 36 is further compressed the distance "d" representing the total length of the elastic displacement device is reduced, thereby linearly increasing the preload or force exerted on the capsule ring accordingly with Hooke's law. The distance reduction "d" here results directly from the increase of distance h1 of the pressure adjustment rings, since these elements are all placed in axial linear direction. Therefore, since the distance h1 decreases in the set of capsules, the preload exerted by the elastic loading device, i.e. springs 36 in the valve element 34 and consequently in the pressure adjustment ring 8, decreases, since the elastic length "d" increases. This configuration results in a simple mechanical control of the back pressure of the valve device 18 using these selectively designed capsules. For example, depending on the type of capsules, the back pressure, that is, the pressure above the atmospheric pressure exerted by the valve device, can be between 5N/cm2 (0.5 bar) and 180N/cm2 (18 bar), plus specifically between 15 N/cm2 (1.5 bar) and 134N/cm2 (13.4 bar), more specifically between 27N/cm2 (2.7 bar) and 87N/cm2 (8.7 bar). These pressure values are here measured by measuring the axial compression force of the engagement surface 35 on the pressure adjusting ring 8 in a closed position of the valve, and dividing by the contact surface between these two parts of the valve device. More particularly, the smaller 1A coffee capsule is designed to dispense "ristretto" (approximately 25 ml) and espresso (approximately 40 ml) with the highest back pressure, due to its longer top ring thickness h1 portion (by eg back pressure values between 100 and 180N/cm2 The medium size coffee capsule 1B is best designed to dispense "lungo" coffee (approximately 100-120 ml) with back pressure values in the range of 50 and 140 N/cm2. The full size capsule is designed to produce long coffee (approximately 150-250 ml) with the lowest back pressure, such as within the range of 5 to 80 N/cm2. Coffee beverage of different quality attributes can be obtained, in particular extraction products comprised between approximately 10 and 30% total solids, between approximately 0.5 to 2.5% by weight of a stable cream. The definition for the production of extraction and total solids for coffee beverage is provided, for example, in EP 1566 .127.
    [083] It should be noted that an identification device is preferably associated with each type of capsule to ensure adjustment of the appropriate parameters in the beverage production device that corresponds to the type of beverage to be dispensed, in particular the volume of beverage (for example , 25, 45, 110, 150, 250 ml, etc) flow rate and/or rotation speed that determines the residence time, and flow rate of the drink or liquid. Identification device can be a code such as a bar code, RFID, color recognition, magnetic or ferromagnetic device, mechanical tips, and so on.
    [084] In the device of the invention, extraction of the beverage from the capsule 1 is obtained by activating the engagement cap 33 of the injection unit 25 (the injector 26 preferably remaining static), the valve device 18, the capsule holder 20 and the capsule together, rotating around the Z axis at an extraction speed, for example between 500 and 16,500 RPM, which can be constant or variable. The speed must be sufficient during extraction to create a centrifugal pressure of liquid in the capsule, enabling opening of the valve device as described.
    [085] The liquid that is injected centrally in the capsule 1 will tend to be guided along the inner surface of the side wall of the body 2 to the inner side of the membrane 4, and then through the perforated outlet openings created in the membrane 4 by the membranes of perforation 24 and then through valve device 18 between surface 35 and top of ring 8. Liquid can be filtered through the interstice created between perforators 27 and membrane 4 to ensure that non-soluble solid, e.g., pore particles. example coffee, are kept in the capsule. Filtration can also be carried out via a separate filter inserted into the capsule. Due to the centrifugation of the liquid in the capsule 1, the liquid and the beverage substance, for example roast and ground coffee powder supplied inside the capsule, are made to interact to form an edible liquid, for example liquid coffee extract. Figure 10 illustrates the system when the beverage is centrifuged out of the capsule and the valve device 18 is opened sufficiently so that liquid passes between the pressure adjusting ring 8 and the valve element 34. Centrifuged beverage receives a pressure enough upstream of the valve device to open it and create an annular restriction opening 42 for liquid flow to be projected towards the impact wall 46 of the manifold at high speed. Opening of the valve device is again obtained by means of the liquid which forces the valve element 34 to further force against the springs 36. The valve element 34 is preferably formed of a non-compressible material such as hard plastic, or metal. However, it should be noted that the valve element and the springs could be made of an integrated compressible part, while ensuring resilient engagement functions such as if made of an annular rubber ring or block. The surface area of the restriction opening is preferably comprised between 0.5 and 15.0 mm2, more preferably 1 and 10 mm2. The surface area of the flow restriction may vary depending on the set back pressure value and the rotation speed of the capsule where in general, the higher the speed, the greater the surface area for a given back pressure.
    [086] As mentioned earlier, for a beverage substance that is essentially roast and ground coffee, the capsule is configured such that the radius R is comprised between 22 and 31 mm, more preferably between 24 and 30 mm, more preferably between 25 and 29 mm. Surprisingly, these strips improve the quality of coffee in the cup. When the radius exceeds the maximum value, the coffee extract experiences a lower aroma content. In particular, flow values are improved and reasonable rotational speed limits are maintained.
    [087] It should be noted that a small liquid leakage through valve device 18 may be required, which helps to vent the gas or air contained in the capsule during filling the capsule with liquid at the beginning of the beverage preparation process . This leakage can be obtained by small radial grooves, holes, protrusions, etc., provided in any of the valve elements (for example, on the surface 35 of the device and/or on the surface of the upper portion 9 of the ring).
    [088] The rotation speed is also adjusted to correspond to a preferred flow rate of the liquid centrifuged out of the capsule. After filling the capsule with water, and during the extraction phase, water continues to be fed into the capsule by the water pump, at a rate that substantially equals the flow rate of the centrifuged liquid, since the capsule is filled with filling liquid the empty ones. At the end of the extraction phase the water pump can be stopped while centrifugation is maintained to empty the residual liquid capsule. This is typically the flow rate that can be controlled during the extraction phase. Water flow can be measured by a flow meter placed in the fluid circuit downstream of the water pump, and controlled by the control unit 40. It could also be theoretically possible to measure the beverage flow downstream of the valve device, but implement a flowmeter in this area is more complicated. The rotation speed fluctuates during the extraction phase to match a reference flow rate as preset in the control unit. The preset flow rate is chosen as a function of the type of capsule and/or beverage to be dispensed. An advantage of capsules with a pressure adjustment ring capable of adjusting different back pressure values also lies in the possibility of providing different flow ranges while centrifugation within a narrower rotation speed range. Therefore, much lower rotation speeds can be operated while still achieving the same coffee diversity. The machine is thus subjected to lower mechanical restrictions when centrifugal forces are lower, so that the system can be designed with lighter material and overall less electrical energy is consumed. The preferred method of controlling beverage flow in accordance with the adjusted back pressure by adjusting the rotation speed of the drive device is described in detail in the also pending European Patent Application 09178382.9 entitled "Capsule system with flow adjustment means" capsule with flow adjustment device"). This patent application is incorporated herein by reference. Naturally other controls of the beverage characteristics are possible, such as setting different predetermined ranges of rotation speeds or different fixed values that are adjusted according to the different types of capsule (1A, 1B, 1C).
    [089] Figures 12 and 13 illustrate another possible embodiment of the capsule of the invention, in which the pressure adjustment ring 5 is formed from a full portion, that is, not hollow, which extends at the same time above and below the plane P from the flange portion 7 of the rim as flange 3 in the axial direction. As in the preceding embodiment, the pressure adjusting ring 8 comprises an upper portion 9 which forms a distance h1 as measured from the transverse plane P and a lower portion 10 which forms a distance h2 when measured from the plane P. h1 is preferably one higher than distance h2. Furthermore, the distance h1 varies depending on the type of capsule in the set, while h2 preferably remains at a constant value in the set of capsules. The flanged collar 3 is preferably formed as an integral part of the body of the capsule which includes the pressure-adjusting ring. Considering the flat top surface of the ring, the radius R is here measured at the highest distance h1 from the ring, but also the closest to the central axis I, that is, at the inner edge of the flat top surface which herewith corresponds to pressure point closest to the ring with respect to the central axis I. Therefore, the radius here is independent of the transverse width of the ring. Of course the top edge of the ring could also be concave with the highest distance h1 being one transversely closest to the central axis I. The force ring can be made of full plastic, such as polypropylene, polyethylene, or a combination of materials plastics such as PP-PE, PP-PET, PE-PET, PP-PE-PET, PP-EVOH-PET or PE-EVOH-PET or combinations of plastic material and metal such as PP-aluminium or PE-aluminium and lacquers, color layers, adhesives, etc. It can be formed with the body through injection molding or thermoforming. The pressure adjustment ring can be rectangular as shown or round or also oval. The flange portion 7 can be flexible to deform during insertion into engagement by the engagement cap of the injection device.
    [090] In another possible mode (not shown), the capsule may comprise a pressure adjustment ring that is part of the top wall, for example, part of the membrane or attached to it, rather than being part of the body. For example, the ring can be formed from an annular extension of the membrane and sealed to it. In this case the pressure adjustment ring extends both axially and transversely beyond the flange portion, but it might not be necessary to be directly connected to it or to be integral with it. A force pressure ring can also be provided which is separated from the body and connected to the flange portion of the body by means of a compression fit or clamping.
    [091] In another possible variant the pressure adjustment ring of the capsule extends only above the "P" plane, but does not extend below the "P" plane towards the bottom of the body. In this case "h1" varies in the set as mentioned above and "h2" is 0 mm.
    [092] The invention also encompasses a fillable capsule kit designed to accommodate beverage substance, eg ground coffee. In this way, the top wall of the capsule is connectable to the body using a removable connecting device, enabling filling of the capsule with beverage substance before insertion into the beverage production device. Connecting device can be adjusted by compression, adhesive, a thread and combinations. For example, the top wall may be a disc of pierceable material, eg thin aluminum foil, which can be attached by the user to a cup-shaped body by a layer of tacky adhesive, after removal of a protective covering strip. said adhesive layer. The adhesive layer can be formulated to provide sufficient adhesion to close the capsule and allow for perforation in the device. The layer can be supported by the membrane and/or flange portion of the body. Examples The purpose of the tests was to evaluate the impact of the radial distance R of the pressure adjusting ring of the capsules of the invention on the content of important aroma compounds to improve quality in the centrifugally extracted coffee cup. The analysis was performed with a mixture of roasted and ground Nespresso Arpegio coffee prepared in a 25 ml cup size. For each system five preparations were made and mixed to provide a representative sample for both systems. The samples were immediately cooled on crushed ice and kept at -20°C until analyzed. All samples were analyzed in triplicate.
    [093] 13 key aroma compounds were selected representing all major compound classes (sulfur compounds, aldehydes, phenols, diketones, pyrazines).
    [094] Absolute concentrations were determined by SPME-GC/MS analyzes using isotope compounds labeled as internal standards (IDA).
    [095] Two different capsule diameters (D) were studied, respectively 52 and 63 mm. The capsule was designed in such a way that the radial radius (R) as defined above was equal to D/2 with a tolerance of ± 0.5 mm.
    [096] Two rotational speeds were tested, 5000 RPM and 10,000 RPM.
    [097] The size of the ground coffee (D4,3 ) tested was 260 microns.
    [098] The results of the aroma content present in coffee beverages prepared by capsules with two different diameters (2.R) are shown in the table below.
    [099] The growth of the diameter from 52 to 63 mm leads to a decrease of aroma compounds in the final beverage. Aroma decay at larger diameter occurs at 5000 RPM as well as at 10,000 RPM. Maximum impact is found for high volatiles at 5000 RPM (28% less) which also comprises various freshness markers such as aldehydes and dimethyl sulfides. At 10,000 RPM the loss is similar for volatile highs and lows and less drastic as at 5000 RPM. Low and medium volatiles were present in amounts 10 to 20% lower for both tested speeds.

    [0101] Although the present invention has been described with reference to its preferred embodiments, various modifications and changes can be made by a person having ordinary skill in the art, without departing from the scope of this invention, which is defined by the appended claims.
