Description

Technical Field

[0001] This invention relates to the field of plant protein processing and extraction technology, and in particular to a protein processing and extraction apparatus. Background Technology

[0002] Soy protein is one of the most widely used high-quality plant protein sources in the food and feed industries. Rich in essential amino acids and possessing excellent emulsifying and water-holding properties, it enjoys strong demand in areas such as meat product improvement, plant-based food preparation, and nutritional supplement production. Protein processing and extraction equipment, as the core equipment for the industrial extraction of soybean protein, must undertake the key functions of "raw material protein dissolution - solid-liquid separation and impurity removal - purification to obtain the target protein." Its performance directly determines the extraction efficiency, recovery rate, and purity of soybean protein.

[0003] Traditional protein processing and extraction devices often adopt a "separate centrifugation and separation equipment" model. The material after centrifugation needs to be manually transferred to the separation equipment, which not only increases the operation steps and prolongs the extraction cycle, but also easily leads to material loss and external contamination during the transfer process, resulting in low extraction efficiency. Moreover, the separation component does not have a precise one-way liquid guiding design, and impurities (such as fibers and unsettled particles) can easily flow back into the supernatant during the separation process, affecting the purity of the target protein in the subsequent acid precipitation step.

[0004] To address this, the present invention proposes a protein processing and extraction device. By integrating a centrifugal assembly with staggered sealing strips and locking components and a separation assembly with one-way liquid passage holes, along with an operating port on the periphery of the equipment chamber and a washable structure, it achieves continuous processing of soybean protein from alkaline protein solubilization, centrifugation to impurity removal, and acid precipitation. At the same time, it solves the problems of cumbersome operation, easy leakage, impurity backflow, and inconvenient maintenance of traditional split devices, ensuring extraction efficiency and target protein purity. Summary of the Invention

[0005] Technical problems solved: Solving the problems of traditional protein extraction devices, such as complicated operation, easy leakage, backflow of impurities, and inconvenient maintenance.

[0006] To address the shortcomings of existing technologies, this invention provides a protein processing and extraction apparatus, thereby solving the technical problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A protein processing and extraction apparatus includes an equipment compartment, the interior of which is divided into an upper compartment and a lower compartment by a partition plate, and the equipment compartment is equipped with a centrifugation component and a separation component; The centrifugal assembly includes a rotating body disposed in the upper chamber, a liquid chamber opened in the middle of the rotating body, an internal gear installed in the middle of the rotating body, an installation component installed in the middle of the partition plate, a second motor installed at the top of the installation component, a second gear installed on the output shaft of the second motor, and a first gear rotatably connected to the lower side of the installation component, which meshes with both the second gear and the internal gear. The separation assembly includes a pressure plate groove at the bottom of the partition plate, a hydraulic plate in the pressure plate groove, a moving rod fixed at the top of the hydraulic plate, the moving rod passing through the partition plate and having a screw inside, and a screw tube threadedly connected to the screw inside the moving rod. A motor is installed in the equipment compartment on the upper side of the upper compartment, and a chain wheel assembly is provided between the motor and the screw tube. The hydraulic plate has multiple annularly arranged liquid passage holes in the middle, a permeable plate is fixed in the middle of the liquid passage holes, a slide rod is slidably connected in the middle of the permeable plate, a sealing plate and a limiting plate are fixed at both ends of the slide rod respectively, the sealing plates are alternately arranged in the middle of the hydraulic plate, and a spring is sleeved on the outside of the slide rod, the spring is located between the adjacent permeable plate and the limiting plate. The rotating body has a connection port on its outer side, which is opened and closed by a cabin plate.

[0008] In one possible implementation, staggered sealing strips are installed between the contact surfaces of the partition plate and the rotating body.

[0009] In one possible implementation, a pull rod is rotatably connected to one end of the cabin plate near the center of the rotating body, and a connecting rod is rotatably connected between the center of the pull rod and the outside of the rotating body; a locking assembly is provided between the pull rod and the connecting rod.

[0010] In one possible implementation, the locking assembly includes a stop rod fixed to the middle of the connecting rod, a rotating ring rotatably connected to the middle of the pull rod, a torsion spring connected between the rotating ring and the pull rod, and a rod pass opening on one side of the rotating ring.

[0011] In one possible implementation, the movable rod is square in design with a hollow cylindrical interior. The movable rod is slidably connected to the middle of the partition plate, and the spiral tube is rotatably connected to the interior of the upper cabin.

[0012] In one possible implementation, the lower periphery of the equipment compartment has multiple operating ports for operating the levers.

[0013] In one possible implementation, there are four liquid tanks and four sets of connection ports arranged symmetrically at the top and bottom. The four sets of connection ports correspond to the four liquid tanks respectively and are connected to the top and bottom ends of the liquid tanks.

[0014] In one possible implementation, there are three gears, arranged in a ring around the periphery of gear two.

[0015] Beneficial effects compared to existing technologies: 1. In this solution, by integrating the centrifugal assembly (including a rotating body with four independent liquid chambers and a gear-gear-internal gear transmission system) and the separation assembly (hydraulic plate and one-way liquid passage structure) into the same equipment chamber, the step of "material transfer between centrifugal equipment and separation equipment" in the traditional extraction process is eliminated. At the same time, multiple sealing barriers are constructed using staggered sealing strips to prevent centrifugal leakage, realizing continuous processing of soybean protein from "alkaline protein solubilization → slag removal → acid precipitation → protein extraction", reducing material loss and external pollution, and significantly improving the continuity and efficiency of the extraction process; 2. In this solution, a locking assembly consisting of a torsion spring, a rotating ring, and a stop bar is designed to fix the pull rod during high-speed centrifugation of the rotating body, preventing the closed chamber plate from accidentally opening due to inertia. Combined with the anti-rotation design of the square moving rod of the hydraulic plate and the precise transmission of the solenoid-screw, it is ensured that the liquid passage hole only allows the supernatant to be separated / returned in one direction (without impurity backflow), thus achieving stable and controllable centrifugation and separation processes, avoiding extraction failures caused by equipment malfunctions, and effectively ensuring the recovery rate of soybean protein. 3. In this solution, the rotating body is stably maintained at the centrifugal speed by the ring gear transmission driven by motor 2, which is precisely adapted to the requirement of "one-time centrifugation to remove fiber and two-time centrifugation to extract protein" of soybean pulp; at the same time, the four liquid tanks process simultaneously, and the four hydraulic plates are driven synchronously by motor 1 through the chain wheel group, realizing batch and uniform extraction, avoiding the efficiency difference of single tank processing, adapting to small and medium-scale mass production scenarios, and improving the practical value and capacity adaptability of the device; 4. In this solution, a liquid passage structure with staggered sealing plates and springs is set in the middle of the hydraulic plate. With the up and down movement of the hydraulic plate, the supernatant can be flowed in one direction (the upper sealing plate opens to guide the liquid when moving down, and the lower sealing plate opens to return when moving up). This effectively avoids the backflow of impurities (such as fibers and unsettled particles) into the supernatant during the separation process. At the same time, the precise separation of the stratified liquid can be completed without additional filtration equipment. This realizes the integrated purification of "separation-return" in the soybean protein extraction process, improving the purity of the target protein and the efficiency of subsequent acid precipitation.

[0019] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can also be implemented in various different forms, and therefore the present invention is not limited to the embodiments described below. In addition, for the purpose of more clearly describing the present invention, parts not connected to the invention will be omitted from the drawings. The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Please refer to Figures 1 to 11 As shown in the figure, this embodiment introduces the specific structure of a protein processing and extraction device, including an equipment compartment 1 that is internally divided into an upper compartment 2 and a lower compartment 3 by a partition plate 4. The equipment compartment 1 is equipped with a centrifugal component for liquid centrifugation and a separation component for processing the stratified liquid after centrifugation.

[0020] The centrifuge assembly includes a rotating body 19 disposed inside the upper chamber 2. Four liquid chambers 20 are opened in the middle of the rotating body 19. An internal gear 21 is installed in the middle of the rotating body 19. An installation component 22 is installed in the middle of the partition plate 4. A second motor 24 is installed at the top of the installation component 22. A second gear 25 is installed on the output shaft of the second motor 24. Three first gears 23 are rotatably connected to the lower side of the installation component 22. The three first gears 23 are arranged in a ring around the second gear 25 and mesh with the second gear 25 and the internal gear 21 at the same time. Specifically, the motor 24 drives the gear 25 to rotate, the gear 25 drives the gear 1 to rotate, which in turn drives the internal gear 21 to rotate, and the internal gear 21 drives the rotating body 19 to rotate inside the upper compartment 2. Soy protein requires two centrifugation processes during extraction. When the raw material to be processed enters the interior of the liquid chamber 20, it is centrifuged by rotating body 19 at high speed along the central axis of motor 24. A series of staggered sealing strips 9 are installed between the contact surfaces of the partition plate 4 and the rotating body 19. The staggered arrangement of the sealing strips 9 is mainly used to create multiple sealing barriers to prevent liquid leakage during centrifugation.

[0021] The outer side of the rotating body 19 has four sets of symmetrically arranged connection ports 26. The four sets of connection ports 26 correspond to the four liquid tanks 20 respectively. Each set of connection ports 26 is symmetrically arranged and communicates with the upper and lower ends of the corresponding liquid tank 20. When centrifugation is performed, the substances inside the liquid tank 20 are separated into layers. Therefore, the upper liquid is discharged through the upper connection port 26 and the lower liquid is discharged through the lower connection port 26.

[0022] The multiple connection ports 26 are opened and closed by slidingly connecting the closure plate 27 on the outside of the rotating body 19. Each of the multiple rotating bodies 19 is rotatably connected to a pull rod 28 near the middle of the rotating body 19. A connecting rod 29 is rotatably connected between the middle of the pull rod 28 and the outside of the rotating body 19. By using the connecting rod 29 as a support, the pull rod 28 rotates along the rotation connection point with the connecting rod 29, thereby driving the closure plate 27 to move up and down, so as to realize the opening and closing of the connection ports 26.

[0023] To ensure that the rotating body 19 rotates at high speed and prevents the pull rod 28 from moving due to inertia, thus preventing the cabin plate 27 from opening accidentally, a locking assembly is provided between the pull rod 28 and the connecting rod 29. The locking assembly includes a stop rod 30 fixedly connected to the middle of the connecting rod 29, a rotating ring 31 rotatably connected to the middle of the pull rod 28, and a torsion spring 32 connected between the rotating ring 31 and the middle of the pull rod 28. A rod opening 33 is provided on one side of the rotating ring 31. When the connecting port 26 is closed by the cabin plate 27, the pull rod 28 and the connecting rod 29 are in a relatively parallel and overlapping state. At this time, rotating the rotating ring 31 makes the rod opening 33 on the rotating ring 31 and the stop rod 30 relatively parallel. If the pull rod 28 is pushed into the middle of the connecting rod 29 in a state parallel to the connecting rod 29, the stop rod 30 will move to the middle of the rotating ring 31 through the rod opening 33. When the rotating ring 31 is rotated, the torsion spring 32 connected to it undergoes elastic deformation, causing the torsion spring 32 to store force. When the stop rod 30 moves to the middle of the rotating ring 31 through the rod opening 33, the rotating ring 31 is released, and the torsion spring 32 rebounds, causing the rotating ring 31 to return to its original position. This causes the rod opening 33 and the stop rod 30 to shift their positions, thereby limiting the movement of the rotating ring 31 through the stop rod 30, thus limiting the rotation of the pull rod 28. This prevents the pull rod 28 from moving due to inertia while the rotating body 19 is rotating at high speed. When it is necessary to move the closure plate 27 to open the connection port 26, repeat the operation. First, rotate the rotating ring 31 so that the through-rod port 33 on the rotating ring 31 and the stop rod 30 are in a relatively parallel position. Then, pull the pull rod 28 to make the pull rod 28 move. Multiple operating ports 34 are provided on the lower periphery of the equipment compartment 1 for operating the lever 28.

[0024] The separation component is mainly used to separate the raw materials that have been centrifuged and formed into layers, so as to remove useless waste and retain the materials that need to be further processed. The separation component includes four pressure plate grooves 5 opened at the bottom of the partition plate 4. Each of the four pressure plate grooves 5 is equipped with a hydraulic plate 7. The top of each of the four hydraulic plates 7 is fixedly connected with a square-shaped moving rod 6. The moving rod 6 passes through the partition plate 4 and the inside of the moving rod 6 is a hollow round tube. The inside of the moving rod 6 is respectively equipped with a screw 8 fixedly connected to the top of the hydraulic plate 7. The inside of each of the four moving rods 6 is equipped with a screw tube 10 threadedly connected to the screw 8. The four screw tubes 10 are rotatably connected to the inside of the upper chamber 2. Specifically, the screw tube 10 is connected to the screw rod 8 by a thread, so that the screw tube 10 drives the screw rod 8 to move up and down when it rotates. In order to make the screw rod 8 move up and down, it is necessary to avoid the screw tube 10 driving the screw rod 8 to rotate at the same time. Therefore, the square design of the moving rod 6 is slidably connected to the middle of the partition plate 4, so that the hydraulic plate 7 and the screw rod 8 connected to the moving rod 6 are restricted by the square shape and cannot rotate. Inside the equipment compartment 1, on the upper side of the upper compartment 2, is installed a motor 11. The output shaft of the motor 11 is connected to the four solenoids 10 by a chain wheel assembly 12. When the motor 11 drives the four solenoids 10 to rotate simultaneously through the chain wheel assembly 12, the solenoids 10 are connected to the screw 8 by threads, which drives the screw 8 and the connected hydraulic plate 7 to move up and down.

[0025] Note that when motor 24 drives the rotating body 19 to rotate for centrifugal operation, the hydraulic plate 7 should be reset to the inside of the pressure plate groove 5 to avoid interference from the hydraulic plate 7 when the rotating body 19 rotates.

[0026] The hydraulic plate 7 has multiple annularly arranged liquid passage holes 13 in its middle section. A permeable plate 14 is fixedly connected to the middle of each liquid passage hole 13. A sliding rod 15 is slidably connected to the middle of each permeable plate 14. A sealing plate 16 and a limiting plate 17 are fixedly connected to both ends of each sliding rod 15, respectively. Figure 7 Multiple sealing plates 16 and adjacent limiting plates 17 are alternately arranged in the middle of the hydraulic plate 7. Half of the sealing plates 16 are fixedly connected to the bottom end of the slide rod 15, and the others are fixedly connected to the top end of other slide rods 15. Springs 18 are sleeved on the outside of multiple slide rods 15. The springs 18 are all located between adjacent permeable plates 14 and limiting plates 17. The rebound force of the springs 18 pushes the limiting plates 17 to drive the adjacent springs 18 to close the liquid passage hole 13. When motor 24 starts and drives hydraulic plate 7 to move up and down, if there is liquid inside liquid tank 20, hydraulic plate 7 continues to move into liquid tank 20. Since some sealing plates 16 are located below water permeable plate 14, they will block liquid passage holes 13. The sealing plates 16 located above water permeable plate 14 will be lifted by liquid through water permeable plate 14 under the action of hydraulic pressure, so that liquid flows into the upper side of hydraulic plate 7 through the corresponding liquid passage hole 13. Similarly, when the hydraulic plate 7 moves upward from the inside of the liquid tank 20, if there is liquid on the upper side of the hydraulic plate 7, the pressure between the hydraulic plate 7 and the partition plate 4 will cause the sealing plate 16 located on the upper side of the permeable plate 14 to move to the middle of the liquid passage 13 under the action of hydraulic pressure, thereby blocking the liquid passage 13. Meanwhile, the sealing plate 16 located on the lower side of the permeable plate 14 will be pressed downward, pushing the sealing plate 16 out from the middle of the liquid passage 13. Then, a passage will be formed between the upper and lower sides of the hydraulic plate 7 through the liquid passage 13, so that the liquid on the upper side of the hydraulic plate 7 can be squeezed from the upper side of the hydraulic plate 7 into the lower side of the hydraulic plate 7. This invention is mainly applied to the extraction of soybean protein, and the specific steps are as follows: S1, Equipment Reset The protein processing and extraction device is adjusted to its initial working state: the hydraulic plate 7 of the separation component drives the chain wheel group 12 through the motor 11, which drives the solenoid 10 to rotate, thereby causing the screw 8 to drive the hydraulic plate 7 to return to the inside of the pressure plate groove 5; the rotating body 19 of the centrifugation component is stationary, the upper and lower connecting ports 26 are closed by the closing plate 27, and the pull rod 28 and the connecting rod 29 are locked by the locking component—rotating the rotating ring 31 makes the rod opening 33 parallel to the blocking rod 30, pushing the pull rod 28 in and releasing the rotating ring 31, the torsion spring 32 returns to its original position, causing the rod opening 33 to deviate from the blocking rod 30, restricting the movement of the pull rod 28; the sealing strip 9 inside the equipment chamber 1 remains in an interlaced fit to ensure no liquid leakage during subsequent centrifugation.

[0027] S2, Construction of alkaline extraction system Operate the operating port 34 on the lower periphery of the operating equipment compartment 1, rotate the rotating ring 31 to make the rod port 33 parallel to the stop rod 30 again, pull the pull rod 28 to move the cabin plate 27 upward, and open the upper connection port 26. The total volume of the four liquid chambers 20 in the middle of the rotating body is adapted according to the ratio of "soybean pulp: NaOH solution = 10:1-15:1". Soybean pulp ground to 80-120 mesh is slowly injected from the upper connection port 26, and then 0.05-0.1 mol / L NaOH solution is injected to adjust the pH of the system to 8.0-9.0, which meets the requirements of alkaline extraction environment. Pushing the lever 28 causes the closing plate 27 to move down and close the upper connection port 26. Repeat the locking component operation to lock the lever 28 and prevent the closing plate 27 from opening accidentally during subsequent centrifugation.

[0028] S3, One centrifugation Start the second motor 24 of the centrifuge assembly. The output shaft of the second motor 24 drives the second gear 25 to rotate. The second gear 25 drives the three ring-arranged gears 23 to rotate synchronously, which in turn drives the inner gear 21 and the rotating body 19 connected to it to rotate at high speed along the central axis of the second motor 24 (the speed is adapted to the centrifugation requirements of soybean pulp, and 3000-5000 rpm is recommended). The soybean pulp in the rotating body 19 separates into layers under the action of centrifugal force: the upper layer is the alkaline supernatant containing dissolved soybean protein, and the lower layer is the undissolved precipitate such as fiber and starch. After the layering interface stabilizes, the second motor 24 is turned off, and the rotating body 19 gradually comes to a stop.

[0029] S4. Primary separation and sediment discharge The motor 11 of the separation component is started. The motor 11 drives the four solenoids 10 to rotate synchronously through the chain wheel group 12. Since the moving rod 6 is square (restricting rotation), when the solenoids 10 rotate, they drive the screw 8 and the hydraulic plate 7 to move slowly downward. The sealing plate 16 located on the upper side of the permeable plate 14 is pushed away from the liquid passage hole 13. The upper alkaline supernatant flows into the upper side of the hydraulic plate 7 through the liquid passage hole 13, realizing the separation from the lower sediment. Unlock the closure plate 27 of the lower connection port 26, open the lower connection port 26, and the lower sediment will be discharged from the lower connection port 26 into the collection container under its own gravity and the slight upward thrust of the hydraulic plate 7. After the discharge is completed, close the lower connection port 26 and lock it.

[0030] S5, Supernatant return The drive motor 11 causes the hydraulic plate 7 to move slowly upward. The supernatant on the upper side of the hydraulic plate 7 is squeezed by the partition plate 4. The sealing plate 16 located below the permeable plate 14 is squeezed downward by the supernatant on the upper side of the hydraulic plate 7. The supernatant flows back into the liquid tank 20 below the hydraulic plate 7 through the liquid passage 13. After the supernatant is returned, the hydraulic plate 7 stops moving.

[0031] S6, Construction of Isoelectric Point Acid Precipitation System Unlock the upper connection port 26 and close the chamber plate 27. Open the upper connection port 26 and slowly inject 1 mol / L hydrochloric acid (HCl) solution. Monitor the pH of the system in the liquid tank 20 in real time. When the pH drops to 4.5±0.2 (isoelectric point of soybean protein), stop the acid injection, close the upper connection port 26 and lock the chamber plate 27 through the locking component.

[0032] S7, Secondary centrifugation Restart motor 24 to drive the rotating body 19 to rotate at the same speed as the first centrifugation. The acid precipitation system in the liquid tank 20 will separate into two layers under the action of centrifugal force: the upper layer is the supernatant containing soluble impurities, and the lower layer is the dense soybean protein precipitate. After the separation is completed, turn off motor 24 and wait for the rotating body 19 to come to a complete stop.

[0033] S8, Secondary Separation The motor 11 of the separation component is started. The motor 11 drives the four solenoids 10 to rotate synchronously through the chain wheel group 12. Since the moving rod 6 is square (restricting rotation), when the solenoids 10 rotate, they drive the screw 8 and the hydraulic plate 7 to move slowly downward. The sealing plate 16 located on the upper side of the permeable plate 14 is pushed away from the liquid passage hole 13. The upper supernatant flows into the upper side of the hydraulic plate 7 through the liquid passage hole 13, realizing the separation from the lower soybean protein precipitate.

[0034] S9, Soybean Protein Precipitation Collection Unlock the closing plate 27 of the lower connection port 26, open the lower connection port 26, and remove the soybean protein precipitate at the bottom of the liquid tank 20 from the lower connection port 26 and collect it into a clean container.

[0035] S10, Waste supernatant discharged. Unlock the closure plate 27 of the upper connection port 26, open the upper connection port 26, and continue to drive the motor 11 to move the hydraulic plate 7 further upward. Under the squeezing action, the waste supernatant on the upper side of the hydraulic plate 7 is discharged from the upper connection port 26 to the waste liquid collection container until the supernatant is completely drained.

[0036] S11, Equipment cleaning and reset Deionized water is injected from the upper connection port 26, and the hydraulic plate 7 is controlled to move up and down to rinse the liquid tank 20, hydraulic plate 7, liquid passage hole 13 and other components. The rinsing wastewater is discharged from the lower connection port 26. After cleaning, the hydraulic plate 7 is reset to the inside of the pressure plate groove 5, all connection ports 26 are closed and the chamber plate 27 is locked, the rotating body 19 is stationary, and the equipment returns to its initial standby state.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
