Definitions
- the invention relates to the preparation of brewed beverages or other brewing products. It relates in particular to extraction devices for preparing brewed beverages or the like from an extraction material contained in a capsule, for example ground coffee. It relates in particular to a perforation device for extraction devices for producing brewing products, for example capsule coffee machines. Furthermore, it relates to a brewing module for such an extraction device and an extraction device.
- Extraction devices for preparing beverages or the like from an extraction material present in a portion package are known, for example, as coffee or espresso machines.
- the portion packages are designed as capsules, in which the extraction material, for example, is airtight.
- the capsule is pierced on two opposite sides. On the first side, an extraction liquid - generally hot water - is introduced. On the second side, the extraction product is discharged from the capsule.
- a considerable pressure of, for example, 5-20 bar can prevail in the interior of the capsule.
- capsule systems have become known in which water is introduced into the capsule on an injection side, while the capsule on the extraction side is initially intact. Under the pressure of the introduced water, the extraction-side boundary of the capsule is pressed against an example ribbed structure and thereby stretched so that it breaks and the extraction product can flow out of the capsule.
- Such a system can only work with a material that is only very slightly plastically extensible and has a yield stress that is achieved when the material is pressed against a rib or the like by the internal pressure of the capsule. As such material so far only aluminum is usable. Examples of such systems can be found in EP 0 521 188 and US 5,897,899.
- the capsule is also pierced on the extraction side by a perforation mandrel (extraction mandrel), for example already by positioning in the brewing chamber and before the onset of the brewing process.
- extraction mandrel extraction mandrel
- the capsule wall of such systems can be made of plastic - for example polypropylene with an oxygen-tight barrier layer - be, in which case the perforation mandrels must be very sharp due to the very large elongation at break of such substances.
- the piercing of such plastic capsules is not trivial.
- the channel through which the extraction product flows through the extraction port may only have a very small diameter
- WO 2008/023057 shows a corresponding means for penetrating a portion packaging with perforation tips, each of which has a surface inclined to the perforation direction with openings in a perforated screen structure. By this means improved transmission properties are to be achieved.
- perforation elements shown in WO 2008/023057 are perforation elements with - J -
- WO 2010/1 18544 shows, inter alia, extraction-side perforation elements, which have the shape of a sheet protruding approximately perpendicularly from the support surface, wherein the sheet is curved, or is composed of a plurality of sheet metal pieces standing at an angle to each other.
- a sieve element is present in the support surface.
- retaining lands are provided which are located inside the perforation elements, i. are arranged in the interior of the area defined by the perforation elements.
- the screen element must be rinsed from time to time, so that no longer accumulates coffee grounds.
- the perforation device has at least one perforation mandrel, which is tapered away from a base, the perforation mandrel defining a lateral surface and having at least one axial rib projecting outward from the lateral surface.
- the rib is non-cutting and the perforation mandrel in particular formed so that the capsule wall is pressed flat against a region of the lateral surface due to a built-up in the interior of the capsule upon introduction of the brewing liquid hydrostatic pressure, wherein due to a remaining Rigidity of the capsule wall arise on both sides of the rib channels through which the extraction product can flow.
- the perforating device may be an extraction device, i. the perforating mandrel is an extrusion mandrel, and the extraction liquid passed through the through-hole (s) is the extraction product conducted from the brewing chamber to a spout.
- the perforation device may further comprise a base member from which the at least one perforation mandrel protrudes; in the assembled state into a brewing chamber interior.
- a base element may, for example, be formed as a base plate. Alternatively, it may also be formed by a housing of the extraction part of the brewing module.
- at least one through-opening for the extraction product can be formed from a front side of the base element (oriented toward the brewing chamber interior) to form a rear side. Through this passage opening (s), the extraction product from the brewing chamber abiliessen or flow into the brewing liquid in this.
- Such a passage opening may be a through hole in the base element, or else in an insert - for example, perforation mandrel socket - or be formed between such and the base member.
- Such a base element in particular base plate, can define a system for the capsule wall (capsule shell), which then also defines the base of the perforation mandrel.
- the perforation device may be designed and tuned with other elements of the extraction device, that during the extraction process, the capsule wall is pressed against the base member.
- the at least one passage opening in the region of the axial rib be arranged, ie in particular one of the points at which the wall of the pierced capsule is kept away from the Perforationsdorn by the rib.
- the capsule wall does not bear on the base element during the perforation process. Then, a volume will remain between the capsule wall and the base element into which the extraction liquid passes and from which it flows through the passage opening (s). Then it is not mandatory that the at least one passage opening is arranged in the region of the rib.
- a rib in the sense of the present text is different from a blade, i. it is non-cutting, has no cutting edge and is therefore dull for a plastic material.
- function of the rib is that the capsule wall rests on her and thus form next to the rib channels.
- the rib is "axial" does not necessarily mean that it is completely parallel to the axis of the perforation mandrel, but may also be slightly oblique, at an angle of, for example, at most 45 ° to an axial course along the shell surface In which case, in particular, it can be arranged slightly helically.
- the perforation mandrel has a base body, which, for example, is substantially cone-shaped or pyramid-shaped (with a selectable number of pyramid side surfaces belonging to the lateral surface) or otherwise tapering.
- the pyramid can be regular or be irregular and straight or crooked.
- a cone shape can be a straight or slanted circular cone or a straight or slated ellipse cone.
- a substantially conical or pyramidal perforation mandrel may also be delimited in its base area, so that the lateral surface has cylindrical partial surfaces at the base.
- the capsule wall After the piercing process, and in particular under an internal pressure built up inside the capsule, the capsule wall is in regions on the base body in regions.
- the rib causes an additional indentation in the capsule. Adjacent to the rib, the capsule wall is held by them locally from the main body, so that a flow channel - or in each case on both sides of the rib depending on a flow channel -.
- Such a flow channel has a number of advantageous properties / effects.
- Foaming effect When the hot brewing liquid is passed under pressure into a narrow channel, a foaming action results. The formation of a
- Foam is very desirable in many brewing products, especially coffee.
- Autoraatician Anpass When brewing coffee from portion capsules a distinction is made between espresso on the one hand and "Caffe Lungo” / “Caffe crema” on the other hand
- Coffee is prepared with finely ground coffee, under high pressure, and scalded with comparatively little liquid Lungo, coarser ground coffee and more water are used, and the brewing pressure is smaller
- the procedure according to the invention entails that by adapting the "brewing pressure" parameter, the passages automatically adapt. With lower brewing pressure, they become larger and allow the passage of more liquid.
- the rib height h is the measure of how far the rib protrudes from the body. It is defined as the extent perpendicular to the lateral surface. The distance of the ribs is measured in the circumferential direction ie along the sheath area in a plane perpendicular to the rib axis.
- a distance a of the ribs from each other is, for example, the rule that this is at least twice, preferably at least three times their height. In a preferred embodiment, this rule also applies to the distance / rib height in the half of the perforation mandrel height hj measured and / or measured in half of the axial extent of the ribs.
- the perforation mandrel, in particular extraction mandrel is, for example, designed so that it is suitable for perforating a filter-free capsule with a capsule wall made of polypropylene with a wall thickness of about 0.3 mm.
- Embodiments of the invention will be discussed below with reference to a multi-rib perforation mandrel; however, the discussion also applies to single-rib perforation mandrels.
- the main body i. the volume enclosed by the lateral surface is three-dimensionally-bodied, i. different from a needle-like or two-dimensional flat shape.
- the ribs rest on the base body and at least partially protrude from areas of the lateral surface that are oblique, i. are in a (non-right) angle to the base plate, so that the lateral surface is inclined away from the support plane and surface norturals on the lateral surface at the location of the rib (s) facing away from the support plane. If there are several ribs, they therefore run towards each other towards the tip.
- the main body may in particular be substantially convex. Unless it is completely convex, but the lateral surface has slightly concave areas, the ribs project so far that they protrude beyond, or at least hit, the so-called convex hull.
- the lateral surface in the vicinity of the contact surface in addition to the example.
- the tip tapering surface portions eg. Conical basic shape
- cylindrical surface-like extending surface sections may be present.
- the number of ribs may in particular be between 2 and 8 or between 2 and 6, and for example be 3 or 4. In the case of a pyramidal base body, for example, exactly one rib may be present per pyramid surface.
- the ribs are, for example, rectangular in cross-section, but other shapes are possible.
- the width of the ribs - the extent in the circumferential direction of the perforation mandrel is, for example, between 0.4 mm and 1.2 mm, in particular between 0.4 mm and
- the ribs do not extend to the tip of the perforation / extend but at an axial distance from this ends, either abruptly or expiring. They preferably extend axially up to the contact surface.
- a substantially parallel channel can run, which enlarges the flow channel, in that the extraction product can also run therein.
- Such Channel is formed in Perforationselement basic body. It can have a substantially constant depth.
- Such a channel increases the flow capacity of said flow channels by increasing the overall cross-section through which the liquid can drain.
- the effects mentioned are not impaired by such a channel.
- the channel or the channels can be dimensioned relatively narrow, in particular they are less wide than the ribs along which they run.
- the passage openings preferably a plurality of passage openings are present-can be arranged directly adjacent to the ribs (or, if the ribs do not reach the base plate, on their projection onto the plane of the base plate).
- the passage openings then extend radially outward from the base body and / or the base body is provided with recesses at the location of the passage openings. If no contact surface formed by a base element is present, against which the capsule wall rests during the brewing process, the passage opening or the passage openings can also be arranged at a distance from the rib.
- the number of perforation mandrels (in particular extraction mandrels) of the perforation device can be selected according to the needs.
- a perforation mandrel for example in the middle of the base plate, is present.
- the invention also provides a brewing module with a device of the type described as well as an extraction device, for example a coffee machine, with such a brewing module.

- the perforation device of the embodiments described below has the appropriate dimensions and properties to perforate a capsule according to WO 2010/1 18543 on the extraction side.
- This document and the description contained therein of the properties of portion capsules, in particular their shape, dimension, material properties and capsule wall thickness, is hereby incorporated by reference.
- the perforation device is suitable, for example, for installation in a brewing module according to WO 2013/1 10206.
- the present invention is not limited to the application for capsules according to WO 2010/1 18543 nor to the use in a brewing module according to WO 2013/110206. Rather, it can be for other capsule dimensions (by adjusting the dimensions of the base plate and optionally the extraction mandrels), other capsule shapes (by adapting the shape of the base plate and possibly arrangement of the extraction mandrels), and other capsule wall textures (without specific modifications or by a suitably adapted choice of materials of the extraction mandrels and the properties of the extraction mandrel tip). In general, the procedure described here is particularly suitable for plastic-walled capsules (which have certain tensile properties other than aluminum); including capsules made from biodegradable materials.
- Any suitable brewing module can be used as a brewing module, in which a suitable capsule inserted therein is pierced by the perforation mandrels described when the brewing module is closed or at the latest when a brewing liquid is introduced.
- the perforation device 1 according to FIGS. 1-3 has a base plate 2 and extraction thorns 3 projecting from the base plate. In use, the extraction mandrels protrude from the base plate into the interior of a brewing chamber and can thus pierce a portion capsule when they are closed.
- extraction mandrels there are i n extraction mandrels, at each corner of the base plate and in the middle one each, although other distributions of extraction mandrels are possible; in particular the middle extraction mandrel is optional. Arrangements with two, three, six, etc. extraction mandrels are possible, and the use of only a single extraction mandrel - eg. In the middle - is not excluded. Also possible are arrangements with different and / or different sized extraction mandrels, for example. A smaller or larger extraction mandrel in the middle.
- Each extraction mandrel has a base body in the form of a four-sided pyramid tapering towards a tip 5, the pyramid being trimmed at the base thereof and confined to a circular base surface, which is particularly evident in FIG. 1 on the basis of the cylindrical surfaces 12 and in FIG good looks.
- the side surfaces 1 1 and the cylindrical surfaces 12 together form the lateral surface of the body.
- an outwardly projecting axial rib 20 Along each of the side surfaces and approximately in the middle thereof extends an outwardly projecting axial rib 20. This has a region of constant cross-section 21 and towards the tip of a leaking portion 22 from.
- the rib 20 does not extend to the top 5 but ends below so that the lateral surface forms a fin-free region towards the tip.
- a naturalleitöffhung 8 is formed in the base plate.
- a small Ausappelimg 14 is provided at the location of the passage openings of the main body of the extraction mandrel so that the passage openings 8 easily can extend into the circular base, which, for example, in Fig. 2 is visible.
- the distance a between adjacent ribs or the height h ( j) of an extraction mandrel according to the definition used above are also plotted in embodiments in which the extraction mandrel is produced on a base which fits into a receptacle in a base element (For example, base plate) is introduced, the height h d is measured exclusive sockets, ie away from the base, in particular bearing surface (if any) away.
- FIG. 4 described below shows the corresponding definition of the rib height h.
- the mode of operation of the ribs is as follows: If the extraction mandrels are pressed against the capsule during closure of the brewing module - this can be pressed, for example, in the case of a cube-shaped capsule according to WO 2013/110206 - this is perforated by the tips 5. The extraction domes penetrate a little way into the capsule interior. Subsequently, hot water is introduced under pressure into the capsule on the injection side.
- the ejection-side perforation and injection device serving this purpose may, for example, be formed according to the prior art and will not be further described here.
- the capsule Due to the pressure prevailing in the capsule interior, the capsule expands - the capsule wall is due to the higher temperature also better deformable - easy.
- the capsule wall is pressed further in the direction of the base plate 2 and at the same time at the location of the extraction mandrels against the lateral surface.
- the double arrows illustrate the hydrostatic pressure which builds up inside the capsule and presses the capsule wall 31 flat against the extraction mandrel.
- the channels 40 now have the effect, on the one hand, that they allow the extraction product to flow away from the capsule through the passage openings.
- the channels 40 due to their limited extent at their approach (on the side towards the tip) also a screening effect, so that the extraction material remains in the capsule and can not flow together with the extraction product.
- the channels automatically become smaller, which has a self-regulating effect (a higher pressure can be maintained), and refines the screen effect as needed, as described above.
- the perforation device 1 has fastening holes 6 in its base plate. These are, for example, suitable for attachment to a scaffold of the brewing module by countersunk screws. Alternatively, such mounting holes 6 or similar attachment structures may also be used for securing with hot caulking (via a heat or ultrasonic deformable spur protruding through the hole) or with a snap mechanism. Instead of four mounting holes as shown, fewer or more fastening holes, for example two fastening holes or, in particular, if there is no central extraction mandrel other than the one shown, a fastening hole can be present.
- the perforation device 1 according to Figures 1-3 is in one piece and, for example, manufactured as an injection molded part of a suitable plastic. Possible materials are plastics, for example PEEK or polyamides, for example glass-reinforced (for example glass fiber reinforced). The use of ceramic materials is possible, for example. Of ⁇ 1 2 0 3 or Zr0 2 . Also possible are metallic materials, for example. Die castings based on aluminum, stainless steel, etc.
- the extraction device 1 it is also possible to construct the extraction device 1 from several parts.
- the extraction mandrels can be manufactured as separate components (for example by glazing or pressing) and then attached to the base plate.
- Perforating mandrels of the type described here can also be used on the injection side, in which case the effect of the ribs is not mandatory in every case and in every capsule material.
- other perforation means can also be used on the extraction side, for example perforating agents according to WO 2010/1 18544.
- the extraction mandrel shown in FIGS. 5a and 5b has instead of four three side surfaces 11 and a corresponding number of ribs 20.
- the extraction mandrel of Figures 6a and 6b has six side surfaces and ribs. The cylindrical surfaces are omitted in the extraction mandrel according to FIGS. 6a and 6b.
- the side surfaces 11 are concave, both in relation to the axial direction and in relation to the circumferential direction.
- the embodiment according to FIGS. 8a and 8b provides convex side surfaces 11.
- FIGS. 9a and 9b like the first described embodiment, provides for four side surfaces 11 which, however, are not at right angles to one another but form a rhombic arrangement. Corresponding shapes with unequal angles between the side surfaces are also possible for a different number of side surfaces and / or non-planar side surfaces.
- Figures 10a and 1b finally show a conical extraction mandrel, i. an extraction mandrel with a circular cross-section, tapering towards the tip 5 lateral surface.
- the extraction mandrel has four ribs 20 distributed regularly along the circumferential direction; a different number of ribs and / or irregular distributions are possible.
- FIGS. 10a and 10b Another feature of the embodiment according to FIGS. 10a and 10b, which can be implemented independently of the configuration of the lateral surface (that is, for example, also in the case of the other extraction mandrel shapes described in this text), is the non-constant cross-sectional area, apart from the outgoing region 22 the ribs.
- the cross-sectional area of the ribs 20 after the outgoing area is maximum and then decreases steadily towards the base area.
- Other courses are also possible - with the mandrel according to FIG. 10 a / 1 b or with other extraction mandrel forms.
- FIG. 11 shows a rib 20 with a trapezoidal cross-section tapered radially outward.
- Figure 12 shows a rectangular cross-section of the rib 20 as in the examples described above, but with a different relationship between height (radial dimension) and width (circumferential extent with respect to the extraction mandrel lateral surface). Specifically, in Figure 12, the height in relation to the width chosen to be significantly larger than in the examples described above.
- FIG. 13 shows a rib 20 with an outwardly convex end, by means of which it is possible for the capsule wall to cling particularly well to the rib radially outwards and thus to be prevented from forming a further liquid channel along the outer edge.
- FIG. 14 shows a concave termination in which such a further fluid channel is conveyed along the rib emitter edge.
- Figure 15 shows a course rounded along the rib base.
- the design of this area affects the shape and size of the fluid channels and can be adapted to the needs.
- crescent-shaped channels may be particularly favorable for the ratio between sieving efficiency and permeation capacity.
- FIG. 16 finally, shows a rib 20 with a triangular cross-section.
- FIGS. 17a-17d an extraction mandrel is drawn on a base 51, which has an alternative form to FIGS. 5-10.
- the through-holes are not present as through-holes in the base plate or in the base of the extraction mandrel, but are formed between the base and the corresponding inner wall of the recess in the base plate, in that the base has groove-like recesses 58 which form channels.
- Figures 18a and 18b show a further embodiment.
- the passage openings on radial bores 61 which lead from the base of the extraction mandrel inwards.
- the extraction mandrel has an outward - i. to the back - open cavity 62 into which the radial holes open.
- the radial bores do not have to run horizontally, but can, for example, also extend obliquely outwards, ie in other words they can also have a non-radial component.
- the extraction mandrel is inserted into a receptacle in the base element-in particular base plate-such that the radial bores are above the receptacle, for example, just at the base of the extraction mandrel protruding away from the base element.
- Figure 19 is similar to that of Figures 1-3. In contrast to this run, however, two grooves 71 along each rib 20 and parallel to this.
- the grooves 71 have a width that is significantly smaller than that of the rib, so that the screening and foaming effect illustrated in FIG. 4 remains, with the gutters 71, the flow capacity is slightly increased.
