System and method for preparing a beverage suitable for consumption, and a use of such a system

The present invention relates to a system for preparing a beverage suitable for consumption.

Such a system is known from Dutch Patent No. 1006039. This patent prepares a coffee extract with a fine bubble layer, provided with at least one inlet for the coffee extract and an outflow opening for draining the coffee extract with a fine bubble layer. The device is described. The inlet is provided with at least one ejection opening that generates a jet of coffee extract when the coffee extract is supplied to the inlet. This known device is provided with a buffer reservoir, which is positioned to eject a jet of coffee extract onto the surface of the coffee extract already contained in the buffer reservoir during use. The advantage of this known device is the ability to prepare coffee extracts with a foam layer of fine bubbles even under low pressure.

<p> An object of the present invention is an entirely new system for preparing beverages suitable for consumption, such as coffee, tea, and / or other beverages.</p>

<p> According to one aspect of the invention, the system includes a device that disposes the beverage under pressure to a nozzle of the system and at least one receiving chamber that can or is located downstream of the nozzle. The arrangement is such that during use, the nozzle ejects a jet of this beverage toward and / or into the receiving chamber at a relatively high speed, and the receiving chamber is located in this receiving chamber. At least one outflow opening for supplying the contained beverage is provided so that the system suppresses or prevents the formation of bubbles in the beverage, especially when the beverage is ejected towards and / or into the receiving chamber. At least consists of.</p><p> During use, the system can, for example, generate a beverage jet under relatively low overpressure to prepare a beverage while suppressing or substantially preventing the formation of foam. The system may be suitable, for example, for preparing substantially foam-free teas, coffees, and / or other foam-free beverages suitable for consumption.</p><p> According to a further elaboration of the present invention, the system decelerates the beverage jet substantially gradually, eg, spreads over a particular surface and / or guides along a deceleration path, and then decelerates the beverage. Is designed to be supplied via the outflow opening described above. In some cases, the decelerated beverage may first be housed or recovered, eg, in a recovery channel, from which it is fed to the outflow opening.</p><p> The system can also be configured to first turn the beverage jet into at least one substantially continuous beverage stream during use and then deliver a substantially continuous beverage stream through the outflow opening. .. Such a continuous beverage stream can also be supplied, for example, to a region of relatively low flow rate of the beverage, eg, a recovery channel, eg, first contained or recovered, from which it is fed to the outflow opening.</p><p> In this way, the formation of bubbles can be effectively prevented. The beverage stream can have, for example, a substantially constant layer thickness or film thickness, especially while the beverage is being decelerated substantially gradually. The beverage flow is, for example, continuous so as to prevent the accumulation of beverages in the receiving chamber, especially in places where the flow rate of the beverages is relatively high. It will be apparent to those skilled in the art that the formation of a continuous beverage stream can be determined, among other things, depending on the beverage flow rate, jet flow rate, beverage composition, and / or other factors. It will be apparent that such factors are easily tailored to each other by trial and error so that this beverage stream can be obtained during use. It will be further apparent that such factors can also be set by conventional computational models or computer simulations. In particular, good results can be obtained by gradually decelerating the beverage downstream of the nozzle.</p><p> According to one aspect of the invention, the system is provided with a foaming prevention surface that receives the beverage jet during use of the nozzle. The foam-preventing surface shall be designed so that the beverage jet can spread and / or flow away along this surface as a beverage layer or beverage film that flows particularly substantially in layers without substantially forming bubbles. Can be done. Such surfaces can be designed in a variety of ways, and some non-limiting examples are described below. The foam formation prevention surface can be, for example, a beverage jet deceleration surface. Preferably, since the anti-foaming surface is a substantially smooth surface, the beverage can flow along this surface without causing substantially turbulence, and in particular can stick to this surface. In this way, for example, it is possible to surprisingly effectively prevent the formation of bubbles by blowing air. It is not intended to be bound by theory, but a possible explanation is, for example, the rate (or energy) of the beverage spreading over this surface, for example, especially if the layer thickness of the beverage membrane remains substantially constant during use. ) Can gradually decrease when viewed in the flow direction. This slowdown (or energy loss) causes the beverage to not have enough energy to be blown into the air. After the beverage flow has slowed down, the beverage flow can be supplied through the outflow opening without forming bubbles.</p><p> According to one aspect of the invention, the system is provided with a beverage jet acceptor that can be or is located downstream of the nozzle, the acceptor, particularly with the beverage directed at or towards this recipient. It is designed to substantially suppress or prevent the formation of beverage foam when ejected into the receiving chamber.</p><p> The beverage jet receiver can, for example, be placed in the receiving room or can be placed. The receiving body may be further provided with the above-mentioned foam formation preventing surface.</p><p> According to an improvement of the present invention, the receiving body can be moved at least from the foam prevention position downstream of the nozzle to another position. In this other position, the acceptor cannot be used, for example, to suppress or prevent foam formation. This other position may include various positions, such as a storage position, a position removed from the receiving chamber, a position where the receiving chamber can actually form bubbles, and the like.</p><p> In one embodiment of the invention, the acceptor is designed to be substantially mushroom-shaped. The receiving body may be provided with, for example, a dish-shaped upper portion having a convex upper surface, and further, for example, a stem extending below the upper portion. The receiving body may further be, for example, at least partially spherical in design and / or flat and / or have a curled surface and / or other design.</p><p> According to one aspect of the invention, the system is designed to substantially prevent turbulence of the beverage during use as it is ejected towards and / or into the receiving chamber. The system can be further designed to substantially prevent the uptake of air from beverages ejected towards and / or into the receiving chamber during use.</p><p> According to one aspect of the invention, the system can be, for example, from a first configuration to a second configuration and vice versa, in which the system is particularly capable of beverages in the receiving chamber. It is configured to substantially suppress or prevent the formation of beverage foam when directed and / or ejected into the receiving chamber, and in the second configuration, the system is designed to increase the formation of beverage foam. It is composed of. In this way, the system can be used to prepare both foam-free and foam-containing beverages, depending on the configuration taken by the system. For example, one or more parts of the system may be removable to make the system from the first configuration to the second configuration and / or vice versa. In addition, one or more parts of the system may be interchangeable with the corresponding parts to make the system from the first configuration to the second configuration and / or vice versa. Such removable and / or replaceable parts can include, for example, foam formation prevention surfaces, receiving chambers, nozzles, and / or other parts.</p><p> According to one aspect of the present invention, the system is provided with a holder that holds a cover (cover filter) that is or is filled with the product to be extracted, and the holder ejects the beverage into the receiving chamber. The nozzles can be provided integrally or non-integrally to allow the nozzles to be provided. The holder may also be placed, for example, above the receiving chamber. The cover may include a pouch, a pad, etc. The cover can consist of, for example, a filtration material to which the product to be extracted is supplied or can contain the product to be extracted. The system may further be provided with, for example, housing components that are placed between the holder and the receiving chamber during use.</p><p> In one aspect of the invention, at least one receiving chamber is configured to substantially suppress or prevent foam formation in the beverage. Such a receiving room can be designed in various ways, as described later herein. One aspect of the invention further relates to a receiving chamber of the system according to the invention.</p><p> Another aspect of the invention provides an assembly in which the holders described above are at least provided, the assembly being designed to substantially suppress or prevent foaming of the beverage, and the assembly is further ejected, for example, a beverage. There will be a nozzle and / or a reception room to receive beverages. A further aspect of the invention relates to a holder for the assembly of the invention.</p><p> According to one aspect of the invention, methods of preparing beverages suitable for consumption, such as coffee and / or tea, particularly utilizing the systems, receiving chambers, assemblies, and / or acceptors according to the invention.

In the present application, the same or corresponding features are indicated by the same or corresponding reference numerals.

FIG. 1 shows a system for preparing a beverage suitable for consumption, for example coffee, which is known from the technical level, and the system includes a device 1 for supplying the beverage to the nozzle 2 of the system under pressure and a nozzle 2. There is at least one receiving chamber 3 that can or is located downstream, the arrangement of which is that the nozzle 2 makes the beverage jet S (not shown in FIG. 1) relatively fast during use. It is designed to be ejected toward and / or into the receiving room 3. The receiving chamber 3 has a bottom 5 and, for example, a substantially cylindrical or conical trapezoidal side wall 8 extending upward from the bottom. The receiving chamber 3 is provided with at least one outflow opening 4 for supplying the beverages contained in the receiving chamber 3. The receiving chamber or part of the receiving chamber can be detachably connected to the housing 30 of the device.

The system shown in FIG. 1 is further provided with a bowl-shaped holder 20 for holding a cover (not shown) to which the product to be extracted is filled or can be filled, and the holder 20 is particularly provided with a beverage. The nozzle 2 is provided to eject the nozzle 2 into the receiving chamber 3. The holder 20 can be placed above the receiving chamber 3, as shown in FIG. The holder 20 is further detachably connected to the housing 30 of the device. The cover to which the product to be extracted is filled or can be filled may include a pouch or the like manufactured from a filter material and filled with the product to be extracted such as ground coffee.

The system shown in FIG. 1 is further provided with a bowl-shaped receiving reservoir 128 arranged in the receiving chamber. During the use of this known system, hot water is placed in the holder 20 from the hot water preparing element 42 and supplied to the top surface of the cover filled with the product to be extracted in order to obtain the extract. it can. Since the extract is ejected into the receiving reservoir 128 by the nozzle 2, the reservoir 128 is filled with the extract. Here, in a known system, the extract is ejected into the liquid surface of the receiving reservoir 128, so that the system can prepare a bubble layer of fine bubbles.

FIG. 2 schematically illustrates a portion of the first exemplary embodiment of the present invention. The first exemplary embodiment comprises a system for preparing beverages suitable for consumption, such as coffee and / or tea. The system is provided with a device 1 that supplies beverages to one nozzle 2 of the system under pressure and a receiving chamber 3 that can or is located downstream of the nozzle 2 and is in use. In addition, the nozzle 2 ejects one jet S of the beverage toward the receiving chamber 3 and / or into the receiving chamber 3 at a relatively high speed. The receiving chamber 3 is provided with at least one outflow opening 4 for supplying the beverage contained in the receiving chamber 3. The system is further provided with a holder 20 that holds a cover 40 that can be filled or can be filled with the product to be extracted, which can be placed above the receiving chamber 3. So far, the design of the system shown in FIG. 2 corresponds to, for example, the corresponding features of the system shown in FIG.

The system shown in FIG. 2 is configured to at least substantially suppress or prevent the formation of bubbles in the beverage, especially when the beverage is ejected towards and / or into the receiving chamber 3. Therefore, it is different from the system shown in Fig. 1. The first exemplary embodiment is designed, for example, to substantially prevent turbulence of the beverage as it is ejected towards and / or into the receiving chamber 3 during use. .. The system can also be designed to substantially prevent the uptake of air by the beverage ejected towards and / or into the receiving chamber 3 during use.

For this purpose, the system shown in FIG. 2 is provided with a three-dimensional foam formation prevention surface A that receives the beverage jet S while the nozzle 2 is in use. This surface A is preferably designed to ensure a gradual but rapid deceleration of the beverage flow in a relatively small space (such as the interior space of the receiving chamber 3) during use. In this exemplary embodiment, the foam-preventing surface A is substantially along this surface A as a beverage layer in which the beverage jet S flows in a particularly substantially layered manner without substantially forming bubbles during use. Designed to be able to continuously spread and / or flow away. The beverage flow of the beverage extending along this plane is shown by line F in FIG.

As shown in FIG. 2, the bubble formation preventing surface A is particularly the outer surface of the dish-shaped upper portion 11A of the receiving body 11 arranged in the receiving chamber 3 downstream of the nozzle 2. As shown in FIG. 2, the foam formation prevention surface A can be provided by the upper surface and the lower surface located downstream of the upper portion 11A, and the beverage can flow from the upper surface to the lower surface during use. Receiving bodies 11 are designed to substantially suppress or prevent the formation of bubbles in the beverage, especially when the beverage is ejected onto the receiving body 11. To this end, the acceptor 11 of the first exemplary embodiment is designed to be substantially mushroom-shaped, with a dish-shaped upper portion 11A having a convex, particularly curved, eg, slightly bulging top surface. A stem 11B extending to the center below it is provided. A spherical foam-preventing surface portion of the receiving body 11, such as a spherical upper surface, may be advantageous for use, especially in the relatively small interior space of the system. The stem 11B can be connected to the receiving plate 5'of the receiving chamber 4 extending below the receiving body 11, and the receiving plate 5'is connected to the upper wall 6 of the receiving chamber 3 by the connecting component 7. The receiving body 11 may extend substantially away from, for example, the bottom of the receiving chamber 3, or vice versa, may be provided above or in the bottom. During use, the receiving body 11 can be placed, for example, substantially in the center of the receiving chamber or at a different position. Of course, the receiving body 11 can also be connected in different ways, for example, to different wall portions of the receiving chamber or to the holder 20. It is believed that such a receiver 11 can surprisingly effectively prevent foam formation, for example, depending on the type of beverage to be prepared and the flow rate of the beverage.

In particular, the system shown in FIG. 2 first transforms the beverage jet S into at least one substantially continuous beverage flow F, which is preferably decelerated gradually during use, and then substantially through the outflow opening 4. Can be designed to supply a continuous beverage stream F to. The foam formation prevention surface A is a substantially smooth flow surface, and this substantially smooth flow surface particularly has a surface roughness Ra or a different surface roughness of less than about 50 μm, more particularly less than about 25 μm. Sometimes it is even more advantageous. It should be noted that the term "smooth" in this application should be understood in a relatively broad sense. As will be described later in the present specification using a second exemplary embodiment, for example, the smooth foam formation preventing surface A is provided with a smooth transition portion, for example, a flow curved portion (for example, a golf ball surface or the like). For example, it can be provided.

Further, the acceptor 11 and the foam formation prevention surface A of the first exemplary embodiment are, for example, substantially rotationally symmetric with respect to the virtual central axis M, respectively. In this exemplary embodiment, the central axis M extends, for example, substantially through the center of reception chamber 3. The virtual central axis M can extend, for example, through the center or central portion of the antifoaming surface, eg, substantially at right angles to such a central or central portion. As shown in FIG. 2, the nozzle 2 is designed to direct the beverage jet S toward the upper center or the central portion of the foam formation prevention surface A, or near the center or the central portion. The perpendicular of the bubble formation prevention surface A on the central axis M is substantially directed to, for example, the nozzle 2. At the position where the beverage jet S collides with the antifoaming surface A, the perpendicular can be substantially parallel to this jet, at least during use. Further, for example, a part of the bubble formation preventing surface A can include a smooth surface portion extending toward the nozzle 2, for example, a central surface portion. In this way, the jet S can spread, for example, proportionally across the bubble formation prevention surface A of the receiving body 11.

The receiving body 11 can have various dimensions to prevent foam formation during use, for example, depending on the type and flow rate of the beverage. For example, the contour of the foam formation prevention surface A, particularly the contour of the dish-shaped upper portion 11A of the receiving body 11, can have a diameter D larger than about half the diameter of the receiving chamber 3. The diameter D can have different values, see, for example, the exemplary embodiments shown in FIGS. 8 and 9 (these are described further herein). These diameters are measured, for example, in a direction across the central axis M. The foam-preventing surface A further extends from the nozzle 2 at a specific distance, such as a distance greater than about 1 mm, more specifically a distance greater than about 2 mm, such as a distance in the range of about 1 mm to 2 mm, or a different distance. Can be done. This distance is preferably such that the beverage spread over the acceptor 11 during use is substantially out of contact with the nozzle 2 or the droplets that may drip around the nozzle 2. In one aspect of the invention, the foam formation prevention surface A is incorporated above or in the receiving chamber 3. On the other hand, the foam formation preventing surface or the component provided with this surface, the receiving body 11 in FIG. 2, may be removable from the receiving chamber 3. The receiving body 11 can be moved at least from the foam prevention position downstream of the nozzle 2, for example, to another position, where the receiving body 11 is not used to suppress or prevent the formation of bubbles.

According to one aspect of the invention, it is advantageous when the system can be at least from the first configuration to the second configuration and vice versa. FIG. 2 shows, for example, a first system in which the system is configured to substantially suppress or prevent the formation of beverage foam, especially when the beverage is ejected towards and / or into the receiving chamber 3. Indicates the position of. In a second configuration (not shown), the system can be configured to increase the formation of beverage foam. To this end, the mushroom-shaped receiving body 11 may be removable from the receiving chamber 3 or may be replaced with the foaming receiving reservoir 128 shown in FIG. 1 or a different foam promoting structure.

Further, in the system shown in FIG. 1 or a similar system, the foam preventer 11 may be placed in the receiving reservoir 128 or a similar reservoir to change the configuration of the system. For example, the receiving body 11 suitable for preventing foam formation may be removably placed in the receiving reservoir 128 and fixed in a suitable foam preventing position with respect to the receiving reservoir using a removable or non-removable bond. And / or may be combined in other ways. The latter bond may include various connecting means, such as snap connections, tightening connections, adhesive connections, and / or other suitable connections.

The present invention can also be embodied, for example, in an assembly in which one holder 20 is provided at least, the assembly being designed to substantially suppress or prevent the formation of beverage foam, especially in this assembly. A nozzle 2 for ejecting the beverage and / or a receiving chamber 3 for receiving the beverage are provided. By designing the appropriate parts of this assembly to be replaceable and / or removable from the system, the system compares, for example, to first prepare a foam-free beverage and then foam the beverage. It is easy to go from the first configuration to the second configuration and vice versa. A holder 4 and / or a receiving chamber 3 specially designed to prevent foaming can be supplied separately from the system, for example to replace the foaming holder and / or foaming receiving chamber of the beverage preparation system. ..

The system shown in FIG. 2 is designed, for example, to supply the beverage under pressure during use, which pressure is, for example, overpressure, eg, in the range of about 0.8 to 2.5 bar, preferably 1.0 to 0.8 bar. Is. The first exemplary embodiment is further designed to supply the nozzle 2 with a beverage flow rate that may be in the range of about 2-8 ml / sec, preferably 5-7 ml / sec during use. In addition, the average diameter of the beverage jets of the system supplied by nozzle 2 during use can be in the range of about 0.5-1.2 mm, preferably about 0.85-0.95 mm. The system can also utilize other values of the above parameters such as pressure, flow rate, and beverage jet diameter described herein.

By placing the tea-filled holder 20 in the cover 40 during use of the system shown in FIG. 2, for example, substantially bubble-free tea can be brewed. Subsequently, a tea extract is obtained, and the extract can be supplied to the nozzle 2 under pressure, so that the beverage is ejected as a jet S onto the upper surface of the receiver 11 at a particularly relatively high speed. As mentioned herein, the beverage can be delivered to the nozzle under a pressure that can range from 0.8 to 2.5 bar, preferably 1.0 to 1.8 bar. Further, the beverage flow rate supplied to the nozzle can be in the range of about 2-8 ml / sec, preferably 5-7 ml / sec.

The acceptor 11 can then spread the beverage over the foaming prevention surface A, but in particular the flow rate and surface A are layers in which the beverage can be in the range of about 0.01-1 mm or different along this surface A. It is preferable that the thickness, that is, the film thickness is substantially reached. This layer thickness can already be reached at a relatively short distance from the area where the beverage jet S on surface A collides. The foam formation prevention surface A provides, for example, a specific deceleration path that can guide the beverage and decelerate relatively gradually. Such gradual deceleration is, for example, a substantially constant deceleration in the direction of beverage flow and / or a non-linear deceleration, a substantially secondary quadratic. deceleration), and / or other decelerations may be included. Preferably, at least the deceleration of the beverage along this foaming prevention surface A is not rapid. For the deceleration path, refer to, for example, a three-dimensional path (for example, the first exemplary embodiment, the second exemplary embodiment, and the fifth exemplary embodiment of FIGS. 2, 7, and 10). ), Or a substantive two-dimensional path (see, eg, the third exemplary embodiment and the fourth exemplary embodiment of FIGS. 8 and 9), or, for example, a one-dimensional path (not shown). Can include.

During use, the beverage jet can, for example, spread substantially continuously in at least one relatively thin layer over the antifoaming surface A and be discharged into at least one outflow opening. As shown in FIG. 2, the beverage can spread over both the upper and lower surfaces of the upper portion 11a of the receiver 11, for example under the influence of adhesive force. Spreading through the lower surface can result in a good deceleration of the beverage, especially if the lower surface is provided with, for example, a concave portion (see FIG. 2). In this way, a substantially continuous, preferably layered beverage stream F can be formed from the beverage jet S. Downstream of the foaming prevention surface A, the beverage flow F, at least the decelerated beverage, can be collected again, for example, and supplied to the outflow opening 4.

3 to 7 show some of the second exemplary embodiments of the present invention. The second exemplary embodiment is similar to the first exemplary embodiment shown in FIG. 2 in that the bottom 5 of the receiving chamber 3 extending opposite the nozzle 2 is provided with a foam forming prevention surface A. Is different. The foam-preventing surface A is provided, for example, with a surface increasing profiling, as seen in cross section (see FIG. 7), in particular a substantially corrugated surface or surface portion. Although the foam formation prevention surface A of the second exemplary embodiment is provided with one or more substantially circular ripples, it is clear that the foam formation prevention surface A can also be corrugated in different ways. Will.

As further shown in FIGS. 3 and 4, the second exemplary embodiment is provided with a holder 20 in the center of the underside of one nozzle 2 (not visible in FIGS. 3 and 4). It has a component 23 that can be placed on top of the holder 20 so that it is provided.

A second exemplary embodiment is further provided, for example, with a substantially cylindrical housing component 21 that can be placed, for example, between the holder 20 and the receiving chamber 4 during use. The housing component 21 can form, for example, a spacer between the holder 20 and the receiving chamber 3 or its bottom 5. The housing component 21 may be provided with a passage 22 that allows the beverage jet S obtained from the nozzle 2 to pass through, a central passage in this exemplary embodiment. The housing component 21 can be coupled to the side wall 8 of the receiving chamber 3 or to a different part of the system using, for example, suitable tightening connections, snap connections, bayonet connections 23a, 24b, or other connections.

In the second exemplary embodiment, the foam formation prevention surface A is provided with a substantially flat central surface portion A1 extending substantially across the ejection direction of the nozzle 2. The bubble formation preventing surface is further provided with a surface portion A2 that surrounds the flat surface portion A and is recessed with respect to the flat surface portion A, and is recessed at least in a direction away from the nozzle 2. This recessed surface portion A2 is substantially surrounded by the raised surface portion A3 of the bubble formation prevention surface A. This raised surface portion A3 can extend at approximately the same height as the flat surface portion A1. A concentric receiving channel 9A that can be surrounded by the side wall 8 of the receiving chamber 3 can be provided around the foam forming prevention surface A, particularly around the raised surface portion A3. The receiving channel 9A provides a beverage collection area for collecting the decelerated beverage flowing in the radial direction and discharging it to the outflow opening 4. The foam formation prevention surface A may be further provided with a recessed discharge portion 9B extending in the radial direction, for example, a discharge portion 9B, in order to discharge the beverage particularly to the outflow opening 4. As shown in the figure, the recessed discharge portion 9B extends through, for example, the raised surface portion A3. It is preferable that various portions of the foam formation prevention surface A are smoothly connected from the central portion A1 when viewed in the radial direction. In addition, the adjacent top and bottom undulations of the anti-foam surface A can be located at various distances X from each other (see Figure 7). As shown in FIG. 7, the foam formation prevention surface A can be provided with some sinusoidal undulations or different relatively gradual curvatures.

According to one aspect of the invention, the antifoaming surface A extends from at least the first level L1 to the second level L2, which is lower than the first level L1 (see FIG. 7), with the first level. The vertical distance Y to and from the second level can include various distances.

The use of the second exemplary embodiment is similar to the use described above of the first exemplary embodiment, in which one beverage jet is ejected onto the central portion A1 of the foam-preventing surface A. .. In a second exemplary embodiment, the beverage is subsequently uniformly radially outward from the central axis M over the undulations or ripples of this surface A over the central portion A1, the recessed portion A2, and the raised portion A3. Can spread. In this case, it is preferable that the beverage forms a relatively thin flow film of a relatively constant thickness. This flow membrane can be significantly decelerated as it spreads over surface A when viewed in the radial direction, which can be accepted by concentric receiving channels 9A. The receiving channel 9A can then be filled with the beverage to a certain height (higher than the film thickness). The radial discharge channel 9B can also ensure, for example, that the beverage level in the recessed portion A2 is kept relatively low during use, but this is not required.

The foam formation prevention surface A of the second exemplary embodiment is a relatively large, preferably smooth surface. The various concentric slopes or undulations of this surface can effectively contribute to the gradual deceleration of the beverage in a relatively small space, thus effectively preventing the formation of bubbles.

FIG. 8 is one of a third exemplary embodiment, which differs from the exemplary embodiment shown in FIG. 2 in that the bubble formation prevention surface A is a substantially two-dimensional, substantially flat surface. Shows the part. In a third exemplary embodiment, the flat foam formation prevention surface A forms the outer surface of the receiving body 11'arranged in the receiving chamber 3 especially downstream of the nozzle 2. In particular, the receiving body 11'is a relatively large disk or the like arranged so as to face the nozzle 2. In the illustrated configuration, the anti-foam surface A of the third exemplary embodiment extends substantially across a beverage jet (not shown) ejected onto the surface A by nozzle 2 during use. The operation of the third exemplary embodiment is performed substantially corresponding to, for example, the operation of the exemplary embodiment shown in FIG. 2, and the beverage is radially along the foam prevention surface A. For example, it can be expanded in the radial direction with respect to the central axis M and can be decelerated.

FIG. 9 differs from the exemplary embodiment shown in FIG. 8 in that the foam formation prevention surface includes a relatively small surface A arranged adjacent to the nozzle 2, according to a fourth exemplary embodiment. Some are shown. In particular, the acceptor 11 of the third exemplary embodiment is a relatively small disc with a substantially flat antifoaming surface A.

FIG. 10 differs from the exemplary embodiment shown in FIG. 2 in that the foam formation prevention surface includes a relatively long surface A of the curled acceptor 11 arranged facing nozzle 2. , A part of the fifth exemplary embodiment is shown. In this case, the foaming prevention surface A is, for example, a rolled into itself or wound onto itself over a specific distance, that is, a curled surface of the acceptor 11''', which provides the beverage flow S. For example, it can be received and decelerated between windings or a curl of this surface A of the receiving body 11'''. The virtual central axis Z of the curl of the receiving body 11'''can extend substantially across the ejection direction of nozzle 2 or in a different direction. Each of such a receiving body 11''' or foam forming prevention surface A allows the beverage to be sufficiently decelerated in a relatively small space.

It is self-evident that the invention is not limited to the exemplary embodiments described. Various modifications are possible within the framework of the invention described in the appended claims. For example, the features of the exemplary embodiments described above can be combined in various ways. For example, the receiving body may be provided with a corrugated bubble formation preventing surface A or the like.
