Description

Technical Field

[0001] The present invention belongs to the field of residue removal from soy products, and specifically relates to a residue removal and filtration device for soy products with multi-stage separation. Background Art

[0002] Residue removal from soy products usually refers to the step of removing soybean dregs during the production of soy products. Soybean dregs are the solid residues remaining after soybeans are ground into soy milk, and their main components are dietary fiber, protein, carbohydrates, etc. Removing soybean dregs can make the taste of soy products more delicate, such as when making soy milk, tofu, etc.

[0003] Traditional methods include the filtration method: pouring the ground soy milk into a gauze or filter screen, and allowing the soy milk to flow out through squeezing or gravity, while the soybean dregs are left in the gauze or filter screen; the centrifugation method: putting the soy milk into a centrifuge, and separating the soy milk and soybean dregs through high-speed rotation. Due to the relatively large density of the soybean dregs, they will settle at the bottom of the centrifuge, while the soy milk remains on the upper layer.

[0004] Traditional residue removal devices for soy products often only use a single method for residue removal, resulting in more soybean dreg particles remaining in the soy products, affecting the taste and texture, and there is still a large amount of soy milk fixed in the large-particle soybean dregs. If not processed, it will lead to a decrease in the yield of soy milk.

[0005] Therefore, the present invention provides a residue removal and filtration device for soy products with multi-stage separation. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A residue removal and filtration device for soy products with multi-stage separation according to the present invention includes a filter frame capable of lifting, an extrusion plate capable of lifting is arranged inside the filter frame, an extrusion seat is arranged at the bottom of the filter frame, a filter pad is arranged between the extrusion seat and the filter frame, a plurality of leakage holes are opened on the top surface of the extrusion seat, a centrifuge is arranged at the lower part on one side of the filter frame, a supernatant transmission pipe is connected between the upper part outside the filter frame and the centrifuge, a reflux pipe is connected between one output end of the centrifuge and the filter frame, and another output end of the centrifuge is connected with a finished product pipe; Put the stock solution that needs to be defatted into the filter box, let it stand for a period of time first to allow the stock solution to settle naturally, so that large particle soy dregs gather at the bottom under the action of gravity. Then, the supernatant is pumped out through the supernatant transfer pipe to the centrifuge. After that, the pressing plate is lowered to press the settled liquid downward, so that it passes through the filter pad, leaving the soy dregs above the filter pad, and the liquid is transferred to the centrifuge. Then the centrifuge rotates at high speed. Under the centrifugal action, the particulate matter in the liquid will move outward, and the liquid in the central part is discharged outward through the finished product pipe, while the remaining liquid rich in particles is injected into the filter box through the return pipe. Then, protease is injected into the filter box to enzymatically hydrolyze the soy dregs, and the protein in the soy dregs can be hydrolyzed into small molecule peptides or amino acids, so that the liquid locked in the original large particle soy dregs can be released. At this time, the filter box contains the mixture of the original soy dregs and the centrifuged particle liquid. After waiting for a period of time, the pressing plate is lowered again to press the liquid in the soy dregs downward. The liquid discharged at this time does not need to be centrifuged again and can be directly discharged and recycled. Finally, the remaining soy dregs need to be discharged outward. An electric heating coil is provided in the filter box, which can change the ambient temperature during the enzyme treatment process to ensure the smooth progress of the treatment process. Through this setting, multi-stage treatment of the stock solution to be treated is realized. It not only ensures that the content of soy dregs in the finished product liquid is extremely low, but also because the enzyme reaction hydrolyzes the large particle soy dregs, releasing the liquid that was originally difficult to release inside. This operation not only increases the output of the finished product liquid, but also greatly reduces the diameter of the subsequent soy dreg particles. Even if soy dregs are mixed in, it will not affect the production of the subsequent finished product. At the same time, since the enzyme is added after the stock solution is extracted and the first pressing, during the enzyme treatment process, the enzyme will not contact and react with a large number of liquids, so there is no need to add too much protease, and the reaction time is also reduced. The finished product liquid after centrifuging the first supernatant and the liquid after enzyme treatment can be stored separately, because the taste of the liquid after enzyme treatment may change, or they can be directly mixed.

[0008] Preferably, the number of the filter boxes and the pressing seats is two. The two filter boxes are arranged in parallel. The centrifuge is located at a position slightly below the middle of the two filter boxes. The two filter boxes and the pressing seats are all connected to the same centrifuge. Since protease and soy dregs need to react for a period of time, prepare another filter box. When the centrifuge is centrifuging, inject the stock solution into the other filter box and let the stock solution stand. When enzyme treatment is carried out in the previous filter box, the supernatant and the bottom liquid after standing in the other filter box can be injected into the centrifuge. When enzyme treatment is carried out in the other filter box, the enzyme treatment in the previous filter box has already ended, and at the same time, the soy dregs have been discharged outward, and the second batch of injected stock solution has already stood still. Thus, the supernatant and the bottom liquid of this stock solution can be injected into the centrifuge. Through this setting, the two filter boxes take turns using the centrifuge, and the time of using the centrifuge coincides with the standing and enzyme treatment time of the other group, thus effectively improving the work efficiency.

[0009] Preferably, winding rollers are fixedly connected to both ends of the filter pad. A support frame is installed between the ends of the two winding rollers. A driving motor is fixedly connected to the end of the winding roller. The width of the filter pad is greater than the width of the extrusion seat. The filter pad is ensured to be straightened by the two winding rollers. The rotation of the winding roller is controlled by the driving motor. When dealing with the final soybean residue, first lift the extrusion plate and the filter frame upward, and then the two winding rollers release and wind the filter pad respectively, so as to move the filter pad with soybean residue to the outside for convenient cleaning. At the same time, move the new filter pad under the filter frame so that it can quickly perform the next operation. The straightened filter pad is higher than the extrusion seat. The filter pad fits with the extrusion seat only under the downward pressure of the filter frame. In this way, even if a relatively thick filter pad is wound around the outside of the winding roller, it will not cause the filter pad to rub against the extrusion seat during the movement, resulting in the spillage of soybean residue. The support frame needs to be fixed to an external support, and the end of the driving motor also needs to be fixedly connected to the outside.

[0010] Preferably, two arc-shaped cleaning plates are sleeved outside the filter pad. A slag material box is arranged below one end of the cleaning plate. The bottom of the cleaning plate is fixedly connected to the top of the slag material box. When the soybean residue moves into contact with the cleaning plate, the arc-shaped cleaning plate will rub the soybean residue, guide the soybean residue to the edge, and finally fall into the slag material box. The filter pad can be reused multiple times. When one side of the filter pad is pulled out, the winding roller can be driven in the reverse direction to make the filter pad perform a filtering operation again. After a certain number of times, replace the entire filter pad roll.

[0011] Preferably, a switching valve is fixedly connected to the top of the centrifuge. Both the supernatant transfer pipe and the bottom liquid transfer pipe are connected to the switching valve. A contactless liquid pump I is installed in the middle of the bottom liquid transfer pipe. A contactless liquid pump II is installed on the top of the switching valve. The switching valve is used to control the input of the supernatant transfer pipe and the input of the bottom liquid transfer pipe. The suction force is generated by the contactless liquid pump II to extract the supernatant and the bottom liquid into the centrifuge. The contactless liquid pump I is used to extract the bottom liquid after the second enzyme treatment and directly transfer it outwards.

[0012] Preferably, a centrifugate transfer pipe is fixedly connected to one output end of the centrifuge. The end of the centrifugate transfer pipe is fixedly connected to communicate with the finished product pipe. Another output end of the centrifuge is fixedly connected to a particle liquid transfer pipe. A contactless liquid pump III is fixedly connected between the particle liquid transfer pipe and the return pipe. The centrifugate transfer pipe is used to transfer the liquid in the middle of the centrifuge during the centrifugation process, which is the finished product liquid. The finished product liquid is directly discharged outwards from the finished product pipe. The liquid on the outside of the centrifuge is input into the filter frame through the particle liquid transfer pipe and the return pipe, and is extracted by the contactless liquid pump III.

[0013] Preferably, a raw material pipe is fixedly connected between the two filtering frames. Feed pipes communicating with the filtering frames are fixedly connected to both sides of the raw material pipe. The raw material pipe and the feed pipes are integrated pipes, including a pipe for conveying the stock solution and a pipe for conveying protease. The height of the connection between the feed pipe and the filtering frame needs to exceed the middle position of the filtering frame to prevent the liquid from surging up the feed pipe during the extrusion process.

[0014] Preferably, a hydraulic rod is arranged above the filtering frame. The bottom of the hydraulic rod is fixedly connected to the extrusion plate. A first spring telescopic rod is fixedly connected between the top of the extrusion plate and the top of the filtering frame. When the hydraulic rod sinks, it will drive the filtering frame and the extrusion plate to move downward simultaneously. When the bottom of the filtering frame fits against the extrusion seat, as the hydraulic rod continues to press down, the first spring telescopic rod elongates, and the extrusion plate continues to press down, thereby extruding the stock solution to allow the stock solution to pass through the filter pad. When the hydraulic rod shortens, it will first cause the extrusion plate to rise, and finally the filtering frame to rise, enabling the normal transfer of the filter pad. Through this setting, one hydraulic rod can control the lifting of the filtering frame and the hydraulic rod with different functions.

[0015] Preferably, a plurality of second spring telescopic rods are fixedly connected to the bottom of the filtering frame. A fitting frame is fixedly connected between the bottoms of the plurality of second spring telescopic rods. The bottom of the fitting frame is made of an elastic material. When the fitting frame presses against the filter pad and the extrusion seat, it will undergo slight deformation to ensure their sealed fit. Moreover, there is a depression on the top surface of the extrusion seat, and the shape of the depression is the same as that of the fitting frame, further ensuring the sealing effect. The second spring telescopic rods shorten when compressed, sealing the fitting frame and the filtering frame, so that the fitting frame has sufficient force to press against the extrusion seat.

[0016] Preferably, a receiving base is fixedly connected to the bottom of the extrusion seat. A drain pipe communicating with the bottom liquid transmission pipe is fixedly connected to the outer bottom of the receiving base. A splitting pipe for extracting the supernatant liquid is fixedly connected to the outside of the filtering frame. The splitting pipe communicates with the supernatant liquid transmission pipe. A reflux valve is fixedly connected between the reflux pipe and the filtering frame. The receiving base guides the bottom liquid of the extrusion seat to flow into the drain pipe and finally be discharged from the bottom liquid transmission pipe. The splitting pipe can synchronously extract the supernatant liquid and is located above the outside of the filtering frame. A filter screen is provided at the end of the splitting pipe to reduce the entry of particles. The reflux valve is used to control the reflux of the particle liquid; the ends of the splitting pipe, the feed pipe, the bottom liquid transmission pipe, and the reflux pipe close to the filtering frame are all made of elastic materials to allow the normal movement of the filtering frame.

[0017] The beneficial effects of the present invention are as follows: 1. A multi-stage separation soybean product residue removal and filtration device according to the present invention pumps the supernatant outwards through a supernatant transfer pipe into a centrifuge. Then, the extrusion plate presses downwards to press the sinking liquid downwards, so that it passes through the filter pad, leaving the soybean dregs above the filter pad, and the liquid is transferred into the centrifuge. Then, the centrifuge rotates at a high speed. Under the centrifugal action, the particulate matter in the liquid will move outwards, and the liquid in the central part is discharged outwards through the finished product pipe, while the remaining liquid rich in particles is injected into the filter frame through the return pipe. Then, protease is injected into the filter frame to enzymatically hydrolyze the soybean dregs, and the protein in the soybean dregs can be hydrolyzed into small molecular peptides or amino acids, so that the liquid blocked in the original large particle soybean dregs can be released. At this time, the filter frame contains the mixture of the original soybean dregs and the centrifuged particle liquid. After waiting for a period of time, the extrusion plate is started again to press downwards to press out the liquid in the soybean dregs. At this time, the discharged liquid does not need to be centrifuged again and can be directly discharged outwards for recovery. Finally, the remaining soybean dregs need to be discharged outwards. Through this setting, multi-stage treatment of the original liquid to be treated is realized, which not only ensures that the content of soybean dregs in the finished liquid is extremely low, but also because the enzymatic reaction hydrolyzes the large particle soybean dregs, releasing the liquid that was originally difficult to release inside. This operation not only increases the output of the finished liquid, but also greatly reduces the diameter of the subsequent soybean dregs particles. Even if soybean dregs are mixed in, it will not affect the subsequent production of the finished product. At the same time, because the addition time of the enzyme is after the original liquid is extracted and the first extrusion, during the enzymatic treatment process, the enzyme will not contact and react with a large number of liquids, so there is no need to input too much protease, and the reaction time is also reduced.

[0018] 2. A multi-stage separation soybean product residue removal and filtration device according to the present invention prepares another filter frame. When the centrifuge is centrifuging, the original liquid is injected into the other filter frame and left to stand. When enzymatic treatment is carried out in the previous filter frame, the supernatant and bottom liquid in the other filter frame after standing can be injected into the centrifuge. When enzymatic treatment is carried out in the other filter frame, the enzymatic treatment of the previous filter frame has already ended, and at the same time, the soybean dregs have been discharged outwards, and the second batch of injected original liquid has already been left to stand, so that the supernatant and bottom liquid of this original liquid can be injected into the centrifuge. Through this setting, the two filter frames take turns using the centrifuge, and the time of using the centrifuge coincides with the standing and enzymatic treatment time of the other group, thus effectively improving the working efficiency.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1 to 7 shown, a multi-stage separation bean product residue removal and filtration device according to an embodiment of the present invention includes a filter frame 1 that can be lifted. An extrusion plate 26 that can be lifted is arranged inside the filter frame 1. An extrusion seat 23 is arranged at the bottom of the filter frame 1. A filter pad 3 is arranged between the extrusion seat 23 and the filter frame 1. A plurality of leakage holes 22 are formed in the top surface of the extrusion seat 23. A centrifuge 11 is arranged below and on one side of the filter frame 1. A supernatant transfer pipe 8 is connected between the upper part outside the filter frame 1 and the centrifuge 11. A return pipe 10 is connected between one output end of the centrifuge 11 and the filter frame 1. Another output end of the centrifuge 11 is connected with a finished product pipe 12; During operation, the undiluted solution that needs to have the residue removed is placed into the filter frame 1. First, it is left to stand for a period of time to allow the undiluted solution to naturally settle, so that large particulate soybean dregs gather at the bottom under the action of gravity. Then, the supernatant is drawn outwards through the supernatant transfer pipe 8 and sent to the centrifuge 11. After that, the pressing plate 26 presses downwards to press the settled liquid downwards, so that it passes through the filter pad 3, leaving the soybean dregs above the filter pad 3, while the liquid is transferred to the centrifuge 11. Then, the centrifuge 11 rotates at high speed. Under the action of centrifugation, the particulate matter in the liquid moves outwards, and the liquid in the central part is discharged outwards through the finished product pipe 12, while the remaining liquid rich in particles is injected into the filter frame 1 through the return pipe 10. Then, protease is injected into the filter frame 1 to enzymatically hydrolyze the soybean dregs, and the protein in the soybean dregs can be hydrolyzed into small molecule peptides or amino acids, so that the liquid locked in the original large particulate soybean dregs can be released. At this time, the filter frame 1 contains the mixture of the original soybean dregs and the centrifuged particulate liquid. After waiting for a period of time, the pressing plate 26 is started again to press downwards to press out the liquid in the soybean dregs. At this time, the discharged liquid does not need to be centrifuged again and can be directly discharged outwards for recycling. Finally, the remaining soybean dregs need to be discharged outwards. An electric heating coil is provided in the filter frame 1, which can change the ambient temperature during the enzymatic treatment process to ensure the smooth progress of the treatment process. Through this setting, multi-stage treatment of the undiluted solution to be treated is achieved. Not only is the content of soybean dregs in the finished liquid extremely low ensured, but also because the enzymatic reaction hydrolyzes the large particulate soybean dregs, the liquid that was originally difficult to release inside is released. This operation not only increases the output of the finished liquid, but also greatly reduces the diameter of the subsequent soybean dregs particles. Even if soybean dregs are mixed in, it will not affect the subsequent production of the finished product. At the same time, since the addition time of the enzyme is after the undiluted solution is extracted and the first pressing, during the enzymatic treatment process, the enzyme will not contact and react with a large number of liquids, so there is no need to input too much protease, and the reaction time is also reduced. The finished liquid after centrifuging the first supernatant and the liquid after enzymatic treatment can be stored separately, because the taste of the liquid after enzymatic treatment may change, or they can be directly mixed.

[0023] There are two filter frames 1 and pressing seats 23. The two filter frames 1 are arranged in parallel. The centrifuge 11 is located at a position slightly below the middle of the two filter frames 1. The two filter frames 1 and pressing seats 23 are both connected to the same centrifuge 11; During operation, since the protease and the soybean residue need to react for a period of time, another filter frame 1 is prepared. When centrifuging in the centrifuge 11, the stock solution is injected into the other filter frame 1, and the stock solution is allowed to stand still. When enzymatic treatment is carried out in the previous filter frame 1, the supernatant and the bottom liquid after standing still in the other filter frame 1 can be injected into the centrifuge 11. When enzymatic treatment is carried out in the other filter frame 1, the enzymatic treatment of the previous filter frame 1 has already ended, and at the same time, the soybean residue is discharged outward, and the second batch of injected stock solution has already been standing still. Therefore, the supernatant and the bottom liquid of this stock solution can be injected into the centrifuge 11. Through this setting, the two filter frames 1 take turns using the centrifuge 11, and the time of using the centrifuge 11 coincides with the standing still and enzymatic treatment time of the other group, thereby effectively improving the work efficiency.

[0024] Both ends of the filter pad 3 are fixedly connected with winding rollers. A support frame 18 is installed between the ends of the two winding rollers. The end of the winding roller is fixedly connected with a driving motor 20. The width of the filter pad 3 is greater than the width of the extrusion seat 23; During operation, the filter pad 3 is kept straight by the two winding rollers. The rotation of the winding rollers is controlled by the driving motor 20. When processing the final soybean residue, the extrusion plate 26 and the filter frame 1 are first lifted upward, and then the two winding rollers respectively release and wind the filter pad 3, so as to move the filter pad 3 with soybean residue to the outside, which is convenient for cleaning. At the same time, a new filter pad 3 is moved to the lower part of the filter frame 1, so that the next work can be carried out quickly; the height of the straight filter pad 3 is higher than that of the extrusion seat 23. The filter pad 3 fits with the extrusion seat 23 only under the downward pressure of the filter frame 1. In this way, even if a relatively thick filter pad 3 is wound around the outside of the winding roller, it will not cause the filter pad 3 to rub against the extrusion seat 23 during the movement, resulting in the spillage of soybean residue; the support frame 18 needs to be fixed to the external support, and the end of the driving motor 20 also needs to be fixedly connected to the outside.

[0025] Two arc-shaped cleaning plates 21 are sleeved outside the filter pad 3. A slag material box 13 is arranged below one end of the cleaning plate 21. The bottom of the cleaning plate 21 is fixedly connected to the top of the slag material box 13; During operation, when the soybean residue moves into contact with the cleaning plate 21, the arc-shaped cleaning plate 21 will rub the soybean residue, guide the soybean residue to the edge, and finally fall into the slag material box 13. The filter pad 3 can be reused multiple times. When one side of the filter pad 3 is pulled to the limit, the winding roller can be driven in the reverse direction to allow the filter pad 3 to perform a filtering operation again. After a certain number of times, the entire filter pad 3 roll is replaced.

[0026] A switching valve 14 is fixedly connected to the top of the centrifuge 11. The supernatant transmission pipe 8 and the bottom liquid transmission pipe 7 are both communicated with the switching valve 14. A non-contact liquid pump I 9 is installed in the middle of the bottom liquid transmission pipe 7. A non-contact liquid pump II is installed on the top of the switching valve 14; During operation, the switching valve 14 is used to control the input of the supernatant transfer pipe 8 and the input of the bottom liquid transfer pipe 7. By generating suction through the contactless liquid pump II, it is used to extract the supernatant and bottom liquid into the centrifuge 11. The contactless liquid pump I 9 is used to extract the bottom liquid after the second enzyme treatment and directly transfer it outwards.

[0027] One of the output ends of the centrifuge 11 is fixedly connected with a centrifugate transfer pipe 16. The end of the centrifugate transfer pipe 16 is fixedly connected and communicated with the finished product pipe 12. The other output end of the centrifuge 11 is fixedly connected with a particle liquid transfer pipe 15. A contactless liquid pump III is fixedly connected between the particle liquid transfer pipe 15 and the reflux pipe 10; During operation, the centrifugate transfer pipe 16 is used to transfer the liquid in the middle of the centrifuge 11 during centrifugation, which is the finished product liquid. The finished product liquid is directly discharged outwards from the finished product pipe 12, while the liquid on the outside of the centrifuge 11 is input into the filter frame 1 through the particle liquid transfer pipe 15 and the reflux pipe 10 and extracted by the contactless liquid pump III.

[0028] A raw material pipe 5 is fixedly connected between the two filter frames 1. Feed pipes 6 communicating with the filter frames 1 are fixedly connected on both sides of the raw material pipe 5; During operation, the raw material pipe 5 and the feed pipes 6 are integrated pipelines, including a pipeline for transporting the original liquid and a pipeline for transporting protease. The height of the connection between the feed pipe 6 and the filter frame 1 needs to exceed the middle position of the filter frame 1 to prevent the liquid from surging up the feed pipe 6 during the extrusion process.

[0029] A hydraulic rod 2 is arranged above the filter frame 1. The bottom of the hydraulic rod 2 is fixedly connected with an extrusion plate 26. A first spring telescopic rod 25 is fixedly connected between the top of the extrusion plate 26 and the top of the filter frame 1; During operation, when the hydraulic rod 2 sinks, it will drive the filter frame 1 and the extrusion plate 26 to move downwards at the same time. When the bottom of the filter frame 1 fits with the extrusion seat 23, as the hydraulic rod 2 continues to press down, the first spring telescopic rod 25 extends, and the extrusion plate 26 continues to press down, thereby extruding the original liquid to make the original liquid pass through the filter pad 3. When the hydraulic rod 2 shortens, it will also first make the extrusion plate 26 rise, and finally the filter frame 1 rise, so that the filter pad 3 can be normally transferred. Through this setting, one hydraulic rod 2 can control the lifting of the filter frame 1 and the hydraulic rod 2 with different functions.

[0030] A plurality of second spring telescopic rods 28 are fixedly connected to the bottom of the filter frame 1. A fitting frame 27 is fixedly connected between the bottoms of the plurality of second spring telescopic rods 28; During operation, the bottom of the fitting frame 27 is made of an elastic material. When the fitting frame 27 presses against the filter pad 3 and the pressing seat 23, it will undergo slight deformation to ensure the sealed fit between the two. Moreover, there is a depression on the top surface of the pressing seat 23, and the shape of the depression is the same as that of the fitting frame 27, further ensuring the sealing effect. The second spring telescopic rod 28 shortens when compressed, causing the fitting frame 27 and the filter frame 1 to be sealed, so that the fitting frame 27 has sufficient force to press the pressing seat 23.

[0031] A receiving base 4 is fixedly connected to the bottom of the pressing seat 23. A drain pipe 24 communicating with the bottom liquid transmission pipe 7 is fixedly connected to the outer bottom of the receiving base 4. A splitting pipe 19 for extracting the supernatant liquid is fixedly connected to the outside of the filter frame 1. The splitting pipe 19 communicates with the supernatant liquid transmission pipe 8. A reflux valve 17 is fixedly connected between the reflux pipe 10 and the filter frame 1. During operation, the receiving base 4 guides the bottom liquid of the pressing seat 23 into the drain pipe 24 and finally discharges it from the bottom liquid transmission pipe 7. The splitting pipe 19 can synchronously extract the supernatant liquid and is located above the outside of the filter frame 1. A filter screen is provided at the end of the splitting pipe 19 to reduce the entry of particles. The reflux valve 17 is used to control the reflux of the particle liquid. The ends of the splitting pipe 19, the feed pipe 6, the bottom liquid transmission pipe 7, and the reflux pipe 10 close to the filter frame 1 are all made of elastic materials to allow the filter frame 1 to move normally.

[0032] During operation, the undiluted solution that needs to have residues removed is placed into the filtering frame 1. First, it is left to stand for a period of time to allow the undiluted solution to settle naturally, so that large particle soybean dregs gather at the bottom under the action of gravity. Then, the supernatant is drawn outwards through the supernatant transfer pipe 8 and sent into the centrifuge 11. After that, the pressing plate 26 presses downwards to press the settled liquid downwards, so that it passes through the filtering pad 3, leaving the soybean dregs above the filtering pad 3 while the liquid is transferred into the centrifuge 11. Then, the centrifuge 11 rotates at high speed. Under the action of centrifugation, the particulate matter in the liquid will move outwards, and the liquid in the central part is discharged outwards through the finished product pipe 12, while the remaining liquid rich in particles is injected into the filtering frame 1 through the return pipe 10. Then, protease is injected into the filtering frame 1 to carry out enzymatic hydrolysis on the soybean dregs, which can hydrolyze the proteins in the soybean dregs into small molecule peptides or amino acids, so that the liquid locked in the original large particle soybean dregs can be released. At this time, the filtering frame 1 contains the mixture of the original soybean dregs and the centrifuged particle liquid. After waiting for a period of time, the pressing plate 26 is started again to press downwards to press out the liquid in the soybean dregs. The liquid discharged at this time does not need to be centrifuged again and can be directly discharged outwards for recovery. Finally, the remaining soybean dregs need to be discharged outwards. An electric heating coil is provided in the filtering frame 1, which can change the ambient temperature during the enzymatic treatment process to ensure the smooth progress of the treatment process. Through this setting, multi-stage treatment of the undiluted solution to be treated is realized, which not only ensures that the content of soybean dregs in the finished liquid is extremely low, but also because the enzymatic reaction hydrolyzes the large particle soybean dregs, releasing the liquid that was originally difficult to release inside. This operation not only increases the output of the finished liquid, but also greatly reduces the diameter of the subsequent soybean dregs particles. Even if soybean dregs are mixed in, it will not affect the production of the subsequent finished product. At the same time, since the addition time of the enzyme is after the undiluted solution is extracted and the first pressing, during the enzymatic treatment process, the enzyme will not contact and react with a large number of liquids, so there is no need to input too much protease, and the reaction time is also reduced. The finished liquid after centrifugation of the first supernatant and the liquid after enzymatic treatment can be stored separately, because the taste of the liquid after enzymatic treatment may change, or they can be directly mixed; Since the protease and the soybean dregs need to react for a period of time, prepare another filtering frame 1. When the centrifuge 11 is centrifuging, inject the undiluted solution into the other filtering frame 1 and let the undiluted solution stand. When enzymatic treatment is carried out in the previous filtering frame 1, the supernatant and the bottom liquid of the undiluted solution that has stood in the other filtering frame 1 can be injected into the centrifuge 11. When enzymatic treatment is carried out in the other filtering frame 1, the enzymatic treatment in the previous filtering frame 1 has already ended, and at the same time, the soybean dregs have been discharged outwards, and the second batch of injected undiluted solution has already stood still, so that the supernatant and the bottom liquid of this undiluted solution can be injected into the centrifuge 11. Through this setting, the two filtering frames 1 take turns using the centrifuge 11, and the time of using the centrifuge 11 coincides with the standing and enzymatic treatment time of the other group, thus effectively improving the work efficiency; The straightening of the filter pad 3 is ensured by two winding rollers. The rotation of the winding rollers is controlled by the drive motor 20. When processing the final soybean residue, the extrusion plate 26 and the filter frame 1 are first lifted upward. Then, the two winding rollers release and wind the filter pad 3 respectively, so as to move the filter pad 3 with soybean residue to the outside, which is convenient for cleaning. At the same time, a new filter pad 3 is moved to the lower part of the filter frame 1, enabling it to quickly carry out the next work. The height of the straightened filter pad 3 is higher than that of the extrusion seat 23. The filter pad 3 fits with the extrusion seat 23 only under the downward pressure of the filter frame 1. In this way, even if a relatively thick filter pad 3 is wound around the outside of the winding roller, it will not cause the filter pad 3 to rub against the extrusion seat 23 during the movement, resulting in the spillage of soybean residue. The support frame 18 needs to be fixed to an external support, and the end of the drive motor 20 also needs to be fixedly connected to the outside. When the soybean residue moves into contact with the cleaning plate 21, the arc-shaped cleaning plate 21 will rub the soybean residue, guiding the soybean residue to the edge and finally dropping it into the residue box 13. The filter pad 3 can be reused multiple times. When one side of the filter pad 3 is pulled to the limit, the winding roller can be driven in reverse to allow the filter pad 3 to perform a filtering operation again. After a certain number of times, the entire filter pad 3 roll is replaced. The switching valve 14 is used to control the input of the supernatant transmission pipe 8 and the input of the bottom liquid transmission pipe 7. The non-contact liquid pump two generates suction to extract the supernatant and the bottom liquid into the centrifuge 11. The non-contact liquid pump one 9 is used to extract the bottom liquid after the second enzyme treatment and directly transfer it outwards. The centrifugate transmission pipe 16 is used to transmit the liquid in the middle of the centrifuge 11 during the centrifugation process, which is the finished product liquid. The finished product liquid is directly discharged outwards through the finished product pipe 12. The liquid on the outside of the centrifuge 11 is input into the filter frame 1 through the particle liquid transmission pipe 15 and the return pipe 10, and is extracted by the non-contact liquid pump three. The raw material pipe 5 and the feed pipe 6 are both integrated pipelines, including a pipeline for transporting the original liquid and a pipeline for transporting protease. The connection height of the feed pipe 6 to the filter frame 1 needs to exceed the middle position of the filter frame 1, so as not to cause the liquid to surge from the feed pipe 6 during the extrusion process. When the hydraulic rod 2 sinks, it will simultaneously drive the filter frame 1 and the extrusion plate 26 to move downward. When the bottom of the filter frame 1 fits with the extrusion seat 23, as the hydraulic rod 2 continues to press down, the spring telescopic rod one 25 extends, and the extrusion plate 26 continues to press down, thereby squeezing the original liquid to make the original liquid pass through the filter pad 3. When the hydraulic rod 2 shortens, it will first make the extrusion plate 26 rise, and finally the filter frame 1 rises, enabling the normal transfer of the filter pad 3. Through this setting, one hydraulic rod 2 can control the lifting of the filter frame 1 and the hydraulic rod 2 to perform different functions. The bottom of the fitting frame 27 is made of elastic material. When the fitting frame 27 presses the filter pad 3 and the pressing seat 23, it will undergo slight deformation to ensure the sealed fit between the two. Moreover, there is a depression on the top surface of the pressing seat 23, and the shape of the depression is the same as that of the fitting frame 27, which further ensures the sealing effect. The second spring telescopic rod 28 shortens when pressed, enabling the fitting frame 27 and the filter frame 1 to be sealed. In this way, the fitting frame 27 has sufficient force to press the pressing seat 23; The receiving base 4 guides the bottom liquid of the pressing seat 23 to flow into the drain pipe 24 and is finally discharged from the bottom liquid transfer pipe 7. The splitting pipe 19 can synchronously extract the supernatant liquid and is located above the outer side of the filter frame 1. A filter screen is provided at the end of the splitting pipe 19 to reduce the entry of particles. The reflux valve 17 is used to control the reflux of the particle liquid; one ends of the splitting pipe 19, the feed pipe 6, the bottom liquid transfer pipe 7, and the reflux pipe 10 close to the filter frame 1 are all made of elastic material, allowing the filter frame 1 to move normally.
