Description

[0001] Method and device for producing a suspension

[0002] The invention relates firstly to a method for producing a suspension, wherein water is pumped from a storage container through a mixing chamber by means of a pump and plant parts of real nuts, kernels, grains and / or other seeds are mechanically crushed by means of a crushing element and mixed with the water in the mixing chamber and the mixture is pressed through a filter which allows the suspension to pass through and retains any pomace remaining from the plant parts.The invention further relates to a device for producing a suspension with a comminution element for comminuting plant parts of real nuts, kernels, grains and / or other seeds, a mixing chamber for mixing the comminuted plant parts with water, a filter which allows the suspension to pass through and retains any pomace remaining from the plant parts, and a pump for pressing the water from a storage container through the mixing chamber and the filter.

[0003] Such a method and device are known from DE 10 2021 104 742 B3. In such methods, the plant parts are mechanically ground in the mixing chamber. The freshness of the plant parts and the vitamins and nutrients they contain are thus essentially preserved until immediately before the suspension is prepared.

[0004] Task

[0005] The invention is based on the object of simplifying the device.

[0006] Solution

[0007] Based on the known method, the invention proposes that a pump impeller serve as the comminution element. Since the pump impeller also assumes the function of the comminution element, it requires no additional drive. The device is thus significantly simplified. Pumps with an impeller are generally known in the form of centrifugal pumps: The centrifugal pump is a particularly simple and robust fluid machine with a rotating shaft that utilizes dynamic forces to convey the mixture of water and plant matter. The radial pump design—i.e., with a radial outlet from the pump—favors the propeller effect of the impeller.

[0008] In a process according to the invention, the suspension preferably flows directly from the mixing chamber into a collecting container. After the suspension has been prepared, the collecting container can be used as a table or drinking vessel for the suspension. In an industrial process, the suspension can be continuously fed into a filling system.

[0009] In a method according to the invention, the storage container is preferably also the collection container. The plant parts are thus mixed with a defined amount of water in a circulating system.

[0010] Preferably, in a process according to the invention, the plant parts are pressed and dried in the form of a tablet and the tablet is introduced into the mixing chamber and comminuted by means of the comminution element.

[0011] Based on the known device, the invention proposes that a pump impeller of the pump serve as the comminution element. The device according to the invention allows the implementation of the method according to the invention and is therefore equally characterized by the advantages described above.

[0012] A device according to the invention can, in particular, be an attachment for a commercially available hand-held or stand mixer. Alternatively, a device according to the invention can have an integrated drive.

[0013] In a device according to the invention, the comminution element is preferably a rasp. The rasp can be made of stainless steel or oxide ceramic, in particular, and integrally formed onto the pump impeller, or it can be glued to a plastic base body of the pump impeller. Stainless steel and oxide ceramic exhibit particularly low wear. The rasp can have radial or spiral teeth. Alternatively, a rasp without regular teeth can be made, for example, of food-safe sandpaper.

[0014] Cutting, grating and rasping surfaces can also be formed inside the housing, on the filter and / or on the pump wheel in order to continuously chop up the pulp.

[0015] Preferably, in a device according to the invention, the filter is a gap with a gap size of at most 0.5 mm. Such a gap retains components of the suspension that exceed the gap size and thus acts as a filter. If the gap is formed in a radial direction between the impeller and the housing, the impeller imposes a radial flow in the gap through adhesion and viscosity of the suspension according to the principle of the Tesla pump. The cross-section of the filter through which the flow determines the residence time of the suspension in the mixing chamber. In particular, the gap has a height of at most 0.2 mm. The suspension is then ready to drink upon exiting the filter. Alternatively, the device can be passed through one or more further filter stages after exiting the filter.

[0016] Alternatively, the filter in a device according to the invention is preferably a perforated metal sheet. A perforated sheet can be well adapted to the desired method according to the invention by selecting the number and geometry of the holes. The holes can be chamfered to prevent clogging. The smooth surface of the sheet facilitates cleaning. Alternatively, the filter can be a wire sieve, a cloth, or a fleece, or a combination of the alternatives.

[0017] Furthermore, in such a device according to the invention, the pump impeller preferably defines the gap. At the narrowest point of the gap, the suspension is then directly forced by the pump impeller through the gap and—since the pump impeller also serves as the comminution element—through the crushed plant matter.

[0018] Preferably, in a device according to the invention, the mixing chamber has a constant, finitely rotationally symmetrical cross-section in a vertical axial direction. A portion of the plant parts, particularly in the form of a tablet, adapted to the mixing chamber in cross-section, is then prevented from rotating about the axial direction by a positive fit. Further preferably, the cross-section has a maximum of six folds. The fold is the number of fixed angles of rotation around a central axis below the full angle in which a geometric figure is projected onto itself.

[0019] Such a device according to the invention preferably comprises a driving element that is axially movable within the mixing chamber and predominantly closes the mixing chamber beneath the plant parts. The driving element can, in particular, comprise a sabot. The pump then draws in the sabot, which pushes the plant parts upward into the mixing chamber. The sabot can have one or more openings through which the water can flow from the reservoir into the mixing chamber. In particular, a tablet pressed from the plant parts can have channels corresponding to the openings, which guide the water to the top of the mixing chamber.

[0020] Alternatively, in a simpler device according to the invention without a drive element, the plant parts can be inserted into a tablet adapted for this purpose, which is sucked in by the pump due to its shape. For this purpose, the tablet can have a radially projecting edge at the bottom, which is retained as a residue by a preferably flexible constriction in the mixing chamber without falling back into the storage container. Furthermore, such a tablet can have a funnel-shaped opening at the bottom of the axis, so that at the end of the process only an outer edge of the tablet remains and is sucked in. Preferably, in a device according to the invention, the drive, a housing with the mixing chamber, the pump wheel and / or the storage container are connected by means of interchangeable connections, in particular clip, clamp, staple, magnetic or bayonet connections. The individual parts can then be easily separated manually, cleaned after use and reassembled.

[0021] A device according to the invention can comprise a particularly variable flow restrictor for the suspension emerging from the filter. The flow restrictor can comprise one or more gaps with adjustable width and / or length. The residence time of the mixture in the mixing chamber can then be individually adjusted for different suspensions.

[0022] In such a process according to the invention, the plant parts are preferably in the form of chunks. Chunks are pieces with the original macroscopic structure of the plant parts, in particular with grain sizes at least partially in the millimeter range and larger. For the purposes of this application, chunks are understood to include both whole and shredded nuts, kernels, cereal grains, and other seeds.

[0023] Preferably, in a process according to the invention, the plant parts are compressed into a tablet form, and are successively grated off the tablet and rinsed with water to the filter. The tablet form simplifies dosing and improves the storage life of the plant parts.

[0024] Preferably, in a process according to the invention, the plant parts are air-dried, coarsely shredded, malted, distilled, at least partially digested, for example, using enzymes, and / or sweetened. Air-drying preserves the valuable natural constituents of the plant parts. Alternatively, other drying methods, particularly freeze-drying, can be considered. The latter significantly shortens the drying process.

[0025] In such a process according to the invention, the plant parts are preferably soaked at least partially in water before drying. The plant parts swell in the pulp and can subsequently be processed more easily. This swelling can be assisted by slightly tempering the pulp to 50 to 60°C.

[0026] Further preferably, in a process according to the invention, the plant parts are dried under an inert atmosphere, in particular under nitrogen. This prevents the introduction of germs into the plant parts during drying.

[0027] Shredding allows for precise portioning, especially of large nuts, kernels, grains, or seeds, and also speeds up the crushing process during beverage production. Alternatively, at least a portion of whole nuts, kernels, grains, and other seeds can be incorporated into the tablet.

[0028] By dissolving, previously insoluble components of the plant parts are modified so that they disperse more easily in water. Dissolving can be achieved by steaming, roasting, sprouting, fermenting, or fermenting.

[0029] Sweetening improves the flavor of the beverage. In particular, starch and long-chain sugars such as glucose in the plant parts can be broken down enzymatically and converted into short-chain sugars such as fructose, or sweeteners can be added.

[0030] In a process according to the invention, the plant parts preferably comprise dry components such as shells, hulls, husks, husks, or awns. The dry components promote the self-cleaning of the filter by the mixture flowing over it.

[0031] In a process according to the invention, a binder, an emulsifier, an oil, a fat, and / or salt is preferably added to the suspension. A binder helps a portion of the plant parts retain its shape better. Plant-based binders such as starch or guar gum are particularly suitable. An emulsifier prevents demixing of the produced suspension. Lecithin is a particularly suitable emulsifier. Oil increases the fat content of the suspension and forms an emulsion with the water that feels similar to natural animal milk. The oil can be mixed with the plant parts or added in one or more capsules, which are mechanically crushed with the plant parts during the production of the suspension. Sugar, sugar-free sweeteners, and salt improve the shelf life of the tablet and also act as flavor enhancers in the suspension.

[0032] Examples of implementation

[0033] The invention is explained below using exemplary embodiments.

[0042] Fig. 7d a detail of the cut,

[0043] Fig. 8a shows a second device according to the invention,

[0044] Fig. 8b a section through the second device and

[0045] Fig. 8c the individual parts of the second device,

[0046] Fig. 9a shows a third device according to the invention, Fig. 9b shows a section through the third device and Fig. 9c shows the individual parts of the third device. The first device 1 according to the invention, shown in Figure 1a in a perspective view obliquely opened from above, is rotationally symmetrical about a vertical axis 2. It consists of a glass storage container 3 and a mixing unit 4 arranged above it, shown in section along the vertical axis 2 in Figure 1a. The closed device 1 is shown in Figure 2a and again in section along the vertical axis 2 in Figure 2b and in a detail in Figure 2c. Figure 3a and a sectioned detail in Figure 3b show the individual parts of the device 1 in an exploded view.

[0047] The storage container 3 initially tapers upwards to a recessed grip 5 and ends in a cylindrical rim 6 that is slightly wider than the recessed grip 5. The storage container 3 has a height 7 of 23 cm and a capacity of 1000 cc up to a fill line 8. The mixing unit 4 consists of a bell-shaped housing 9 with an annular seal 10 to the storage container 3, a drive 11, a pump 12 driven by the latter, a mixing chamber 13 and a drive element 14. The drive 11 is an electric motor with an output of 600 W and is supplied with power via a cable (not shown). A button 15 for switching on the drive 11 is arranged at the top of the housing 9.

[0048] The pump 12 is a radial pump with a cylindrical housing 16 and a pump impeller 17 driven by the drive 11 around the vertical axis 2. The housing 16 has an internal diameter 18 of 70 mm and a height 19 of 14 mm, as well as 32 vertically extending passages 20 extending radially outward. A filter (not shown) is firmly connected to the housing 16 in front of the passages 20. The filter consists of a stainless steel wire mesh. The pump impeller 17 has a diameter 21 of 64 mm and a height 22 of 12 mm and 24 radially extending blades 24 formed beneath a plate 23.

[0049] Centrally between the blades 24, the pump impeller 17 has a nozzle 25 penetrating downwards through the housing 16, to which a plate-shaped comminution element 26 is attached. The comminution element 26 is designed on its underside as a rasp with spiral teeth (not shown). The mixing chamber 13 has a square cross-section in the direction of the vertical axis 2 with an edge length 27 of 44 mm and rounded corners, as well as a height 28 of 57 mm.

[0050] The drive element 14 consists of a guide plate 29 and a sabot 30. The sabot 30 has a guide socket 31 with a star-shaped cross-section, which is guided in a through hole 32 of the guide plate 29 and ends in a stop 33.

[0051] To carry out a method according to the invention, the storage container 3 is filled with water 34 up to the fill line 8, and a tablet 35 pressed from plant parts is inserted into the mixing chamber 13. The guide plate 29 is snapped into the mixing chamber 13 with a bayonet connection (not shown), and the mixing unit 4 is placed onto the storage container 3 as shown in Figures 2a / b and tightly connected to the storage container 3 with two clamps (not shown). The tablet 35 is then approximately half submerged below a level 36 of the water 34 in the storage container 3.

[0052] When the drive 11 is started at a speed of 10,000 rpm, the pump 12 creates a vacuum in the initially air-filled mixing chamber 13, which draws the water 34 from the reservoir 3 through the guide plate 29, around the sabot 30, and through the mixing chamber 13 to the comminution element 26 and further to the blades 24. The sabot 30, also drawn in by the vacuum, presses the tablet 35 against the comminution element 26, which rotates with the pump wheel 17. The teeth of the comminution element 26 successively rasp off the tablet 35 and the plant parts and mechanically crushes them.

[0053] The water 34 flowing over the crushing element 26 mixes with the plant parts, and the mixture is pressed by the blades 24 through the filter, which retains a pomace (not shown) and allows only the suspension (also not shown) to pass through. Coarse plant parts remain in the space between the blades 24 and the filter and are further mechanically crushed by the rotating pump impeller 17. The suspension flows radially outward from the housing 16 through the passages 20, flows downwards back into the storage tank 3, and mixes there with the water 34.

[0054] When the tablet 35 is scraped off, the stop 33 simultaneously strikes the guide plate 29, thus preventing damage to the sabot 30. The torque of the pump 12 drops abruptly, and the drive 11 automatically shuts off. The mixing unit 4 is now detached and removed from the storage container 3, and the ready-to-eat suspension can be poured from the storage container 3. For easier handling, the storage container 3 can be closed by means of a lid (not shown) with a pouring spout.

[0055] To clean the device 1, the device 1 and in particular the mixing unit 4 are disassembled into the individual parts shown in Figure 3a / b:

[0056] The bayonet connection of the guide plate 29 on the mixing chamber 13 is released, and the drive element 14 is separated from the mixing chamber 13, and the latter is also separated from the housing 16 by a bayonet connection (not shown). The comminution element 26, which is positively connected to the nozzle of the pump wheel 17 and magnetically held thereto, is removed. The housing 16 is separated from the housing 9 by a bayonet connection (again not shown). The filter is removed from the housing 16, the pump wheel 17 is pulled off the drive 11, and the seal 10 is removed from the housing 9.

[0057] The second device 37 according to the invention, shown in Figures 4a and 4b in the opened state corresponding to the first device 1, in Figures 5a and 5b in the closed state and in Figures 6a and 6b in its individual parts, essentially corresponds to the first device 1, but differs from it in some details:

[0058] The reservoir 38 is a right circular cylinder. The two-part housing 39 consists of a bell-shaped drive housing 40, which is widened at the bottom in a hat-like manner with a wide rim 41, to which an initially cylindrical, then conically tapered, drain housing 43 is connected, finally ending in a cylindrical nozzle 42.

[0059] The housing 44 of the pump 45, enclosed by the drain housing 43, has an internal diameter 46 of 104 mm and a height 47 of 13 mm. A filter 48 made of stainless steel wire mesh is loosely inserted into the housing 44. The pump impeller 49 has a diameter 50 of 100 mm and a height 51 of 12 mm. The comminution element 52 is integrated into the pump impeller 49, and the blades 53 are arranged radially outside the comminution element.

[0060] The implementation of a method according to the invention with the second device 37 differs from the implementation with the first device 1 in further details: The mixing unit 54 is loosely placed on the storage container 38 without a sealing element, as shown in Figure 5a / b, and the suspension flows from the housing 44 first through the drain housing 43 back into the storage container 38. For cleaning, the drain housing 43 is separated from the drive housing 40, as shown in Figure 6a / b, and the filter 48 is removed from the housing 44.

[0061] After cleaning the individual parts under running water 34 or in the dishwasher, the devices 1, 37 are reassembled in the reverse order for reuse.

[0062] In other methods according to the invention, loose coarse plant parts - for example a mixture of whole nuts, kernels and almonds - are processed with the devices 1, 37 instead of the tablet 35.

[0063] Further devices according to the invention (not shown) essentially correspond to one of the aforementioned devices 1, 37, but differ in that instead of the housing 9 with the drive 11 on the pump 12, 45 they have an adapter for a commercially available hand blender or a through-opening or grooves on the hand blender 30 for the water 34 in the sabot 30, or they have no sabot at all. The third device 55 according to the invention shown in Figures 7a to 7d is attached to a stylized, commercially available hand blender 56. It consists of a housing 58 that is rotationally symmetrical about a longitudinal direction 57 of the hand blender 56, a drive element 59 and a round pump wheel 60, which are essentially made of plastic.

[0064] The hand blender 56 has a power output of 600 W and is powered by a cable (not shown). A connection cover 61 of the hand blender 56 has a bayonet lock (not shown) on its circumference. A drive shaft 62 with a socket 63 for the rotational mounting of various standardized attachments (not shown) is guided through the connection cover 61 in the longitudinal direction 57.

[0065] The housing 58 encloses a mixing chamber 65, which has a square cross-section rounded at the corners 66 in the longitudinal direction 57, with an edge length 67 of 44 mm and a height 68 of 57 mm. At the top 69, the housing 58 is thickened to a diameter 70 of 65 mm and merges into a circular-cylindrical collar 71. The collar 71 has a ring of 32 vertically extending passages 72 extending radially outward, and above them, the counterpart to the bayonet lock of the connection cover 61 (not shown in detail).

[0066] The impeller 60 has a thickness 73 of 4 mm and a diameter 74 of 60 mm, an octagonal recess 75 matching the nozzle 63, and a glued-on rasp 76 made of zirconium ceramic with spiral teeth (not shown). Zirconium magnets 77 are incorporated into the recess 75 and the nozzle 63. These magnets hold the impeller 60 to the drive shaft 62 after the device 55 is attached to the hand blender 56.

[0067] The drive element 59 consists of a guide plate 78 closing off the bottom of the housing 58 and a sabot 79. The sabot 79 has a guide socket 80 with a star-shaped cross-section, which is guided through the guide plate 78 and ends in a stop 81. The stop 81 prevents the sabot 79 from separating from the housing 58. To carry out a method according to the invention, a portion of plant parts is placed in the housing 58 closed off at the bottom by the sabot 79, the pump wheel 60 is attached to the drive shaft 62 and the housing 58 to the connection cover 61, and the device 55 is held under water in a storage container (not shown). An annular gap 82 with a gap dimension 83 of 0.2 mm remains between the rasp 76 and the housing 58.

[0068] When the hand blender 56 is started at a speed of 10,000 rpm, the impeller 60 generates a radial flow in the gap 82 and a vacuum in the mixing chamber 65, which draws the water from the reservoir through the underside 64 of the housing 58, around the sabot 79, and through the mixing chamber 65 to the impeller 60. The sabot 79, also drawn in by the vacuum, presses the plant parts against the rotating impeller 60, which, as a comminution element, successively grates and mechanically crushes them.

[0069] The water flowing over the impeller 60 mixes with the ground plant matter. The mixture is drawn through the gap 82 by the suction created in the gap, which retains coarse components ("pomace") and allows only the suspension to pass through. The suspension flows radially outward from the housing 58 through the passages 72, flows back into the storage container, and mixes there with the water. The water, the plant matter, the suspension, and the pomace are not shown.

[0070] Once the plant parts have been grated, the stop 81 strikes the underside 64 of the housing 58, thus preventing damage to the sabot 79. The torque of the hand blender 56 drops suddenly; the change in speed serves as an acoustic signal to switch off. The device 55 is now removed from the storage container, and the ready-to-drink suspension can be poured from the storage container. For easier handling, the storage container can be provided with a pouring spout. To clean the device 55, first loosen the bayonet connection of the housing 58 at the connection cover 61, and then remove the pump wheel 60 from the drive shaft 62. Shake out any pomace remaining in the housing 58. After cleaning the individual parts under running water or in the dishwasher, the device 55 is reassembled in reverse order for reuse.

[0071] The fourth device 84 according to the invention shown in Figures 8a to 8c essentially corresponds to the third device 55, but instead of the hand blender 56 has an integrated drive 85 and a straight-cylindrical storage container 86 which can be tightly closed by the drive 85.

[0072] The storage container 86 has a square cross-section rounded at the corners 87 with an edge length 88 of 90 mm, a height 89 of 150 mm and a circumferential recessed grip 90 as well as a capacity of 500 cc.

[0073] A further device according to the invention, not shown, corresponds essentially to the fourth device 84, but has a storage container with a height of 220 mm and a capacity of 1000 cc.

[0074] The drive 85 has a 600 W electric motor 91, which is powered by a cable (not shown). A button 92 for switching the drive on is located at the top of the drive 85. At the bottom of the drive 85, a drive shaft 93 of the electric motor is guided through a connection cover 94 for the housing 95 with the mixing chamber 96. The pump impeller 97 is removably attached to the drive shaft 93.

[0075] Figure 8c shows, by way of example, a portion of plant parts pressed into the form of a tablet 98. In methods according to the invention, such tablets 98 or loose, coarse plant parts (not shown)—for example, a mixture of whole nuts, kernels, and almonds—are processed using the devices 55, 84 according to the invention.

[0076] The fifth device 99 according to the invention, shown in Figures 9a to 9c, also essentially corresponds to the third device 55, but is attached as an attachment to a stylized, commercially available blender 100. The guide nozzle 101 of the drive element 102 of the fifth device 99 extends outward through the lid 103 of the blender 100. Once the plant parts have been grated, the stop 104 strikes the lid 103.
