Description

Technical Field

[0001] This invention relates to the field of plant enzymatic hydrolysis technology, specifically to a plant beverage enzymatic hydrolysis device and method. Background Technology

[0002] Enzymatic hydrolysis technology plays a crucial role in the production of plant-based beverages. Enzymatic hydrolysis is a process that uses biological enzymes to hydrolyze large molecules in plant raw materials, transforming them into easily digestible and absorbable small molecules. To improve the taste, flavor, nutritional value, and production efficiency of plant-based beverages, enzymatic hydrolysis devices have been developed. These devices achieve highly efficient enzymatic hydrolysis of plant raw materials by precisely controlling the conditions of the enzymatic hydrolysis reaction, such as temperature, pH value, and the type and amount of enzymes. With the continuous development of the beverage market and the increasing diversification of consumer demands, the research and application of enzymatic hydrolysis devices for plant-based beverages have become increasingly important. Through continuous technological innovation and optimization, enzymatic hydrolysis devices for plant-based beverages are playing an increasingly significant role in improving the quality of plant-based beverages, reducing production costs, and increasing production efficiency.

[0003] Furthermore, in the field of Traditional Chinese Medicine (TCM), plant-based beverages have been applied in various aspects. In pre-prepared TCM plant-based beverages, the preparation process often requires enzymatic hydrolysis and purification. A patent titled "A Production Device and Method for Ginseng Peptides," publication number CN118126823B, addresses this issue. Existing ginseng peptide enzymatic hydrolysis mixing equipment mostly uses stirring blades for mixing. However, reaction equipment with stirring blades presents the problem of inconvenience in directly recovering ginseng fragments from the hydrolysis device. This problem is encountered in the enzymatic hydrolysis process of existing plant-based beverages. This patent, however, utilizes the up-and-down movement of the stirring and extruding components to mix the ginseng fragment mixture and the enzymatic hydrolysate, while also extruding the ginseng fragments and simultaneously absorbing the liquid. The pump, filter screen, and placement rack enable the recovery of fine materials. Furthermore, the electromagnet assembly, combined with the magnetically conductive metal parts, facilitates the recovery of ginseng fragments. Compared to existing enzymatic hydrolysis devices that utilize stirring mechanisms, this method eliminates the need for stirring blades, preventing ginseng fragments from adhering to them and hindering removal. However, it involves secondary manual compression of ginseng and other plants during movement. During this compression process, some ginseng may remain above the extension ring, preventing complete mixing and reducing the degree of mixing in the enzymatic hydrolysis process. Therefore, this paper proposes a plant beverage enzymatic hydrolysis device and method. Summary of the Invention

[0004] The purpose of this invention is to provide a plant beverage enzymatic hydrolysis device and enzymatic hydrolysis method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plant beverage enzymatic hydrolysis device, comprising an enzymatic hydrolysis tank, two upper transmission pipes respectively connected to the outside of the enzymatic hydrolysis tank, a filter structure connected to the end of the upper transmission pipe away from the enzymatic hydrolysis tank, the water outlet end of the filter structure being connected to the inside of the enzymatic hydrolysis tank, a bidirectional motor fixedly connected to the bottom of the enzymatic hydrolysis tank, the output shaft of the bidirectional motor penetrating the outer wall of the enzymatic hydrolysis tank and fixedly connected to a bidirectional threaded rod, an upper extrusion plate and a lower extrusion plate respectively threadedly connected to the outside of the bidirectional threaded rod, a plurality of enzymatic hydrolysis water inlet holes being opened on the outside of the upper extrusion plate, a second one-way valve being connected to the outlet end of the enzymatic hydrolysis water inlet holes, a plurality of inclined spray holes being opened on the outside of the lower extrusion plate, a first one-way valve being connected to the outlet end of the inclined spray holes, the inner diameter of the inlet of the inclined spray holes being larger than the inner diameter of the outlet, and the inclined spray holes being inclined.

[0007] Preferably, the interior of the intermediate elastic segment is integrally formed with multiple grooves, and the inner walls of the multiple grooves are integrally formed with outwardly convex elastic membranes, and the multiple outwardly convex elastic membranes are arranged around the guide post.

[0008] Preferably, the inner wall of the groove is integrally formed with a pull rope, the end of the pull rope away from the groove is fixedly connected to the upper surface of the convex elastic membrane, and the end of the pull rope near the convex elastic membrane is tapered.

[0009] Preferably, two guide slide rods are fixedly connected to the inner bottom wall of the enzymatic hydrolysis tank, and two through holes are opened on the outside of both the upper extrusion plate and the lower extrusion plate, with the guide slide rods inserted into the through holes.

[0010] Preferably, the filtration structure includes a filter barrel, the inlet of which is connected to the upper transmission pipe, the outlet of which is connected to a lower transmission pipe, the end of which is away from the filter barrel being connected to the enzymatic hydrolysis barrel, a filter screen being snapped into the inside of the filter barrel, and a check valve being connected to the ends of both the lower and upper transmission pipes away from the filter barrel.

[0011] Preferably, the enzymatic hydrolysis tank is fitted with an upper sealing cap, and a positioning hole is provided at the center of the bottom of the upper sealing cap. The end of the bidirectional threaded rod away from the bidirectional motor is inserted into the interior of the positioning hole, and a top magnetic suction plate is fixedly connected to the bottom of the upper sealing cap.

[0012] Preferably, both the upper sealing cap and the outer wall of the enzymatic hydrolysis tank are fixedly connected with sealing ears, and the outer side of the sealing ears is provided with threaded holes, with positioning bolts inserted into the inside of the threaded holes.

[0013] Preferably, multiple auxiliary extrusion balls are fixedly connected to adjacent sides of the upper extrusion plate and the lower extrusion plate, and the auxiliary extrusion balls outside the upper extrusion plate and the lower extrusion plate are staggered.

[0014] The present invention also provides a method for enzymatic hydrolysis of plant beverages, comprising the following steps:

[0015] S1. Place the plant particles between the upper and lower extrusion plates and pour the enzymatic hydrolysate into the enzymatic hydrolysis tank.

[0016] S2. Start the bidirectional motor to drive the bidirectional threaded rod to rotate. During the rotation of the bidirectional threaded rod, the upper extrusion plate and the lower extrusion plate will continuously separate and move closer to each other. During the process of moving closer to each other, the enzymatic hydrolysate located at the bottom of the enzymatic hydrolysis tank will be pushed to the top of the enzymatic hydrolysis tank, and the enzymatic hydrolysate will be continuously moved and mixed with the plant particles.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In this invention, the up-and-down movement of the upper and lower extrusion plates not only extrudes the plant particles, but also allows the enzymatic hydrolysate to be squeezed into the plant particles during the extrusion process, ensuring full contact between the hydrolysate and the plant particles. After the hydrolysate has fully contacted the plant particles, it can be squeezed out of the plant particles. The hydrolysate is then returned to the plant, and the returned hydrolysate, combined with the secondary impact of the enzymatic hydrolysis tank, flips the plant particles, turning the accumulated plant particles over. During the flipping process, the plant particles and the hydrolysate are thoroughly mixed again, further enhancing the enzymatic hydrolysis and mixing effect of the plant particles.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, such as Figure 1 As shown, this application discloses a plant beverage enzymatic hydrolysis device and method, including an enzymatic hydrolysis tank 100. Two upper transmission pipes 101 are connected to the outside of the enzymatic hydrolysis tank 100. A filter structure is connected to the end of each upper transmission pipe 101 away from the enzymatic hydrolysis tank 100. The water outlet of the filter structure is connected to the inside of the enzymatic hydrolysis tank 100. A bidirectional motor 105 is fixedly connected to the bottom of the enzymatic hydrolysis tank 100. The output shaft of the bidirectional motor 105 passes through the outer wall of the enzymatic hydrolysis tank 100 and is fixedly connected to a bidirectional threaded rod 106. The external of the bidirectional threaded rod 106 is threaded with an upper extrusion plate 107 and a lower extrusion plate 108. The external of the upper extrusion plate 107 is provided with multiple enzymatic hydrolysis water inlet holes 110. The outlet end of the enzymatic hydrolysis water inlet hole 110 is connected to a second one-way valve 112. The external of the lower extrusion plate 108 is provided with multiple inclined spray holes 109. The outlet end of the inclined spray hole 109 is connected to a first one-way valve 111. The inner diameter of the inlet of the inclined spray hole 109 is larger than the inner diameter of the outlet, and the inclined spray hole 109 is inclined.

[0035] Specifically, the internal space of the enzymatic hydrolysis tank 100 is divided into an enzymatic hydrolysate moving chamber above the upper extrusion plate 107, an extrusion chamber between the lower extrusion plate 108 and the upper extrusion plate 107, and an enzymatic hydrolysate storage chamber located below the lower extrusion plate 108 by the upper extrusion plate 107 and the lower extrusion plate 108. During use, the operator places the plant particles above the lower extrusion plate 108 and pours the enzymatic hydrolysate into the enzymatic hydrolysis tank 100. After placing both the enzymatic hydrolysate and the plant particles, the upper extrusion plate 107 is threaded onto the outside of the bidirectional threaded rod 106, and the upper sealing cover 600 is closed. After the mixing and enzymatic hydrolysis preparation is completed, the bidirectional motor 105 is started to drive the bidirectional threaded rod 106 to rotate continuously. During the continuous rotation of the bidirectional threaded rod 106, the upper extrusion plate 107 and the lower extrusion plate 108 continuously move closer and further apart. As the lower extrusion plates 108 continuously approach each other, they continuously extrude plant particles located inside the extrusion chamber between the upper extrusion plate 107 and the lower extrusion plate 108. During the extrusion process, the enzymatic hydrolysate and plant juice in the plant particles are further separated. During the separation process between the upper extrusion plate 107 and the lower extrusion plate 108, the lower extrusion plate 108 moves downward due to the rotation of the bidirectional threaded rod 106, while the upper extrusion plate 107 moves upward due to the rotation of the bidirectional threaded rod 106. As the upper extrusion plate 107 moves upward, it gradually reduces the space of the enzymatic hydrolysate moving chamber. As the space inside the enzymatic hydrolysate moving chamber gradually decreases, the enzymatic hydrolysate located inside the enzymatic hydrolysate moving chamber passes through the one-way valve inside the upper transfer pipe 101 and gradually enters the filtration structure. After the enzymatic hydrolysate passes through the filtration structure, the filtration structure filters out the residue in the enzymatic hydrolysate, reducing the amount of residue that re-enters the enzymatic hydrolysis tank 100.

[0036] Furthermore, during the rotation of the bidirectional motor 105, the forward rotation of the bidirectional motor 105 will cause the upper extrusion plate 107 and the lower extrusion plate 108 to move closer to each other. When the upper extrusion plate 107 and the lower extrusion plate 108 move closer to each other, the lower extrusion plate 108 will cause the plant particles above to gradually move and approach the upper extrusion plate 107. As the upper extrusion plate 107 and the lower extrusion plate 108 continue to move closer, the upper extrusion plate 107 will cooperate with the lower extrusion plate 108 to continuously extrude the plant particles located inside the extrusion chamber. During the continuous extrusion of the plant particles, the enzymatic hydrolysate located in the plant particles will be squeezed out and, due to the extrusion pressure, will be squeezed into the enzymatic hydrolysis water inlet 11. Inside the enzymatic hydrolysate, after it continuously enters the enzymatic hydrolysate inlet 110, the enzymatic hydrolysate inlet 110 will transport the squeezed enzymatic hydrolysate to the enzymatic hydrolysate moving chamber located above the upper extrusion plate 107, thereby separating the enzymatic hydrolysate from the plant particles. After continuous extrusion for 1-2 minutes, the extrusion of the plant particles is stopped, and after waiting for 15-50 seconds, the bidirectional motor 105 is started in reverse. After the bidirectional motor 105 is started in reverse, it will drive the bidirectional threaded rod 106 to rotate in reverse. During the reverse rotation of the bidirectional threaded rod 106, the upper extrusion plate 107 and the lower extrusion plate 108 will separate from each other, and the upper extrusion plate 107 will move upward. As the pressure plate 107 moves upward, it gradually reduces the space inside the upper enzymatic hydrolysis chamber. With this shrinking space, the hydrolysate is gradually injected into the upper transfer pipe 101 and transported through it to the filter tank 102 and the lower transfer pipe 103, ultimately reaching the hydrolysate storage chamber below the enzymatic hydrolysis tank 100. Meanwhile, the lower pressure plate 108 moves downward. During this downward movement, the lower pressure plate 108 gradually contacts the hydrolysate flowing back into the hydrolysate storage chamber. Because the lower pressure plate 108 also gradually compresses the internal space of the hydrolysate storage chamber during its downward movement, the hydrolysate is also compressed by the lower pressure plate. 108 Extrusion: When the hydrolysate is extruded, it will push open the first one-way valve 111 above the lower extrusion plate 108, thus passing through the hydrolysis tank 100 and re-entering the extrusion chamber. When the hydrolysis tank 100 is tilted and the diameter of the outlet is small, the hydrolysate will be rapidly rushed out of the outlet of the hydrolysis tank 100 due to the increased pressure during its passage through the hydrolysis tank 100. The hydrolysate rushing out of the outlet of the hydrolysis tank 100 can lift and turn over the plant particles accumulated on the lower extrusion plate 108. As the hydrolysate continuously enters the extrusion space, it can drive the plant particles to continuously turn and mix, thus achieving secondary mixing of the hydrolysate and the plant particles.

[0037] Furthermore, when the enzymatic hydrolysate and plant particles are further mixed, the bidirectional motor 105 is restarted in the forward direction, causing the bidirectional motor 105 to drive the plant particles and enzymatic hydrolysate to be squeezed and mixed again between the upper extrusion plate 107. The whole process is repeated multiple times to ensure that the enzymatic hydrolysate and plant particles are fully mixed. In addition, the lower extrusion plate 108 can also provide an immobilized enzyme fluidized bed for the enzyme in the enzymatic hydrolysis, thereby enhancing the enzymatic hydrolysis effect of the plant particles.

[0038] like Figure 4 As shown, an upper sealing cap 600 is snapped onto the enzymatic hydrolysis tank 100. A positioning hole is provided at the center of the bottom of the upper sealing cap 600. The end of the bidirectional threaded rod 106 away from the bidirectional motor 105 is inserted into the positioning hole.

[0039] Specifically, during the process of attaching the sealing cap 600, the top end of the bidirectional threaded rod 106 can be positioned through the positioning hole at the bottom center.

[0040] like Figure 4 As shown, the filtration structure includes a filter barrel 102. The inlet of the filter barrel 102 is connected to the upper transmission pipe 101, and the outlet of the filter barrel 102 is connected to the lower transmission pipe 103. The end of the lower transmission pipe 103 away from the filter barrel 102 is connected to the enzymatic hydrolysis tank 100. A filter screen 700 is snapped into the inside of the filter barrel 102. Both the ends of the lower transmission pipe 103 and the upper transmission pipe 101 away from the filter barrel 102 are connected to check valve plates.

[0041] Specifically, in the filtration structure, when the enzymatic hydrolysate enters the upper transfer pipe 101, the upper transfer pipe 101 will transport the enzymatic hydrolysate to the filter tank 102, and the particulate molecules in the enzymatic hydrolysate will be filtered through the filter screen 700 inside the filter tank 102. After filtration, the enzymatic hydrolysate will be transported to the enzymatic hydrolysis tank 100 through the lower transfer pipe 103. The one-way valve connected at the port of the upper transfer pipe 101 and the filter tank 102 can prevent the enzymatic hydrolysate from flowing back from the upper transfer pipe 101 and the lower transfer pipe 103.

[0042] like Figures 1-4 As shown, both the upper sealing cap 600 and the outer wall of the enzymatic hydrolysis tank 100 are fixedly connected with sealing ears 601. The outer side of the sealing ear 601 has a threaded hole, and a positioning bolt is inserted into the inside of the threaded hole. During the enzymatic hydrolysis process, the upper sealing cap 600 needs to be snapped onto the upper part of the enzymatic hydrolysis tank 100, and the upper sealing cap 600 is positioned on the enzymatic hydrolysis tank 100 by threading the bolt into the inside of the sealing ear 601.

[0043] like Figure 5As shown, multiple auxiliary extrusion balls 800 are fixedly connected to one side of the upper extrusion plate 107 and the lower extrusion plate 108, and the auxiliary extrusion balls 800 on the outside of the upper extrusion plate 107 and the lower extrusion plate 108 are staggered.

[0044] Specifically, the plant particles can be further compressed by the auxiliary compression balls 800 outside the upper compression plate 107 and the lower compression plate 108, thereby enhancing the compression effect on the plant particles.

[0045] like Figures 4-7 As shown, two guide slide rods 500 are fixedly connected to the inner bottom wall of the enzymatic hydrolysis tank 100. Two through holes are opened on the outside of the upper extrusion plate 107 and the lower extrusion plate 108, and the guide slide rods 500 are inserted into the through holes.

[0046] Specifically, the upper extrusion plate 107 and the lower extrusion plate 108 are guided by two guide slide rods 500, and the guide slide rods 500 prevent the upper extrusion plate 107 and the lower extrusion plate 108 from rotating instead of moving up and down due to the bidirectional threaded rod 106.

[0047] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, the up-and-down movement of the upper extrusion plate 107 and the lower extrusion plate 108 can not only extrude the plant particles, but also squeeze the enzymatic hydrolysate into the plant particles during the extrusion process, so that the enzymatic hydrolysate can fully contact the plant particles. After the enzymatic hydrolysate has fully contacted the plant particles, the enzymatic hydrolysate in the plant particles can be squeezed out. After squeezing out, the enzymatic hydrolysate is returned, and the returned enzymatic hydrolysate, together with the enzymatic hydrolysis tank 100, impacts and flips the plant particles a second time, flipping the accumulated plant particles. During the flipping process, the plant particles and the enzymatic hydrolysate are fully mixed again, further enhancing the enzymatic hydrolysis mixing effect of the plant particles.

[0048] Example 2: Although the upper extrusion plate 107 and the lower extrusion plate 108 can completely squeeze out the enzymatic hydrolysate from the plant particles and re-extract it into the plant particles to achieve multiple extrusion mixing, during the multiple extrusion mixing process, some plant particles inevitably enter the enzymatic hydrolysis water inlet hole 110 of the upper extrusion plate 107, causing the plant particles to block the enzymatic hydrolysis water inlet hole 110. This prevents the enzymatic hydrolysate from passing through the enzymatic hydrolysis water inlet hole 110 into the upper enzymatic hydrolysate moving chamber. To address the above technical problems, this application proposes the following technical solution to solve the above technical problems, specifically:

[0049] like Figure 7 and Figure 9As shown, the center of the second one-way valve 112 is integrally formed with an intermediate elastic section 200, the bottom of the intermediate elastic section 200 is fixedly connected with a guide post 201, the center of the guide post 201 is fixedly connected with a first magnetic block 202, and one side of the inclined nozzle 109 is fixedly connected with a second magnetic block 203.

[0050] Specifically, during use, when the upper extrusion plate 107 and the lower extrusion plate 108 approach each other and compress the plant particles, when the plant particles are squeezed into the enzymatic hydrolysis water inlet 110, the guide post 201 can prevent the plant particles from completely entering the enzymatic hydrolysis water inlet 110. When the upper extrusion plate 107 and the lower extrusion plate 108 are about to separate, the first magnetic block 202 will be attracted by the second magnetic block 203, causing the first magnetic block 202 to deform and move downwards along the middle elastic section 200. At the same time, when the first magnetic block 202 and the middle elastic section 200 move downwards, they will drive the guide post 201 to move downwards, thereby pushing out the plant particles stuck inside the enzymatic hydrolysis water inlet 110. When the upper extrusion plate 107 and the lower extrusion plate 108 are separated to a sufficiently far distance, the second magnetic block 203 and the first magnetic block 202 will lose their mutual attraction, and thus return to their original position through the middle elastic section 200.

[0051] like Figure 4 As shown, the bottom of the upper sealing cover 600 is fixedly connected to the top magnetic plate 104.

[0052] Specifically, when the upper extrusion plate 107 moves to a position close to the top magnetic suction plate 104, the top magnetic suction plate 104 will generate a repulsive force with the first magnetic suction block 202, thereby pushing the guide column 201 to move downward again through the first magnetic suction block 202, and repeatedly guiding the inside of the enzymatic hydrolysis water inlet hole 110 through the guide column 201 to avoid the plant particles getting stuck and blocked inside the enzymatic hydrolysis water inlet hole 110.

[0053] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, when the upper extrusion plate 107 and the lower extrusion plate 108 approach each other to extrude plant particles, the guide post 201 can block the plant particles from entering the enzymatic hydrolysis water inlet 110 during the extrusion process. Furthermore, the mutual attraction between the first magnetic block 202 and the second magnetic block 203 drives the guide post 201 to move downward and, in conjunction with the deformation of the intermediate elastic section 200, pushes out the plant particles that are blocked inside the enzymatic hydrolysis water inlet 110 during the downward movement of the guide post 201, thereby reducing the phenomenon of plant particles blocking the enzymatic hydrolysis water inlet 110.

[0054] Example 3: Considering that plant particles may become stuck inside the enzymatic hydrolysis inlet hole 110 during continuous compression, although the up-and-down movement of the guide post 201 can reduce and prevent larger plant particles from entering the enzymatic hydrolysis inlet hole 110, some plant particles inevitably become stuck directly between the enzymatic hydrolysis inlet hole 110 and the guide post 201 during continuous compression, thus blocking the guide post 201 and preventing it from moving up and down, and also preventing the second one-way valve 112 from opening in time. To address the above technical problems, this application proposes the following technical solution to solve them:

[0055] like Figures 10-11 As shown, the interior of the intermediate elastic section 200 is integrally formed with multiple grooves, and the inner walls of the multiple grooves are integrally formed with outwardly convex elastic membranes 300. The multiple outwardly convex elastic membranes 300 are arranged around the guide post 201.

[0056] Specifically, during use, when the bidirectional threaded rod 106 rotates in opposite directions, causing the upper extrusion plate 107 and the lower extrusion plate 108 to separate from each other, the gradual upward movement of the upper extrusion plate 107 will gradually reduce the space of the enzymatic hydrolysate moving chamber. As the space gradually shrinks, the water pressure in the enzymatic hydrolysate will gradually increase. As the water pressure gradually increases, the greater water pressure will squeeze the convex elastic membrane 300. When the convex elastic membrane 300 is squeezed, it will convexly expand. When it convexly expands, it can fill the space around the enzymatic hydrolysate inlet hole 110 and the guide post 201 from top to bottom, thereby pushing the plant particles stuck between the enzymatic hydrolysate inlet hole 110 and the guide post 201 out of the interior of the enzymatic hydrolysate inlet hole 110 again.

[0057] Furthermore, the reason why the guide post 201 that can fill the enzymatic hydrolysis inlet hole 110 is not chosen is because the guide post 201 that fills the enzymatic hydrolysis inlet hole 110 will affect the passage of the enzymatic hydrolysate and will also affect the tilting of the second one-way valve 112.

[0058] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, the convex elastic membrane 300 can generate convex expansion by water pressure during the upward movement of the upper extrusion plate 107. During the convex expansion, the gap between the enzymatic hydrolysis water inlet 110 and the guide post 201 can be filled. During the filling process, the plant particles stuck in the gap between the enzymatic hydrolysis water inlet 110 and the guide post 201 are pushed out, reducing the phenomenon of plant particles stuck in the gap between the enzymatic hydrolysis water inlet 110 and the guide post 201.

[0059] Example 4: Considering that the convex elastic membrane 300 needs to be thin and soft enough to provide a certain convex pushing effect, and that the convex elastic membrane 300 needs to produce a certain convex effect, if the convex elastic membrane 300 is too soft and thin, excessive stretching may cause the convex elastic membrane 300 to rupture. To address the above technical problems, this application proposes the following technical solution to solve the above technical problems, specifically:

[0060] like Figures 10-11 The inner wall of the groove is integrally formed with a pull rope 400. The end of the pull rope 400 away from the groove is fixedly connected to the upper surface of the convex elastic membrane 300. The end of the pull rope 400 near the convex elastic membrane 300 is tapered.

[0061] Specifically, multiple pull ropes 400 are connected to the inner wall of the groove, and the other end of the pull ropes 400 is connected to the convex elastic membrane 300. When the convex elastic membrane 300 is compressed and expands, it will extend. When the convex elastic membrane 300 extends, the pull ropes 400 will also move with the extension of the convex elastic membrane 300. When the convex elastic membrane 300 expands to a certain extent, the pull ropes 400 will pull the convex elastic membrane 300 to stop it from extending further, thereby reducing the phenomenon of rupture caused by excessive extension of the convex elastic membrane 300.

[0062] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 3, in this embodiment, the pull rope 400 can be used to pull the convex elastic membrane 300 during the expansion process, limiting the expansion degree of the convex elastic membrane 300 to a specified degree, so that the convex elastic membrane 300 can only expand to a specified degree. When the upper extrusion plate 107 pushes the enzymatic hydrolysate completely into the upper transmission tube 101, the pressure of the enzymatic hydrolysate on the convex elastic membrane 300 disappears, thereby avoiding excessive damage and rupture caused by excessive expansion of the convex elastic membrane 300.

[0063] This invention also provides a method for enzymatic hydrolysis of plant beverages, comprising the following steps:

[0064] S1. Place the plant particles between the upper extrusion plate 107 and the lower extrusion plate 108, and pour the enzymatic hydrolysate into the enzymatic hydrolysis tank 100.

[0065] S2. Start the bidirectional motor 105 to drive the bidirectional threaded rod 106 to rotate. The speed of the bidirectional motor 105 is 400-1000 rpm. During the rotation of the bidirectional threaded rod 106, the upper extrusion plate 107 and the lower extrusion plate 108 will continuously separate and move closer to each other.
