Description

Technical Field

[0001] The present invention belongs to the technical field of protein mixing, and specifically relates to a mixing device and a mixing method for producing drawn protein. Background Art

[0002] The mixing of drawn protein raw materials is one of the important steps in the production of drawn protein, which involves the precise proportioning and sufficient stirring of various raw materials to ensure the quality and taste of the final product. The main raw materials of drawn protein include low-temperature soybean meal (oil content less than 1%), soy protein isolate, and wheat gluten. The selection of these raw materials has a crucial impact on the quality and taste of drawn protein.

[0003] Chinese Patent CN113634156A discloses an automatic batching device for producing drawn protein, including a bottom plate. The top outer wall of the bottom plate is welded with a mounting frame, and evenly distributed material barrels are welded on one side of the mounting frame. The bottom outer wall of the material barrel is welded with a housing, and a mixing barrel is arranged on the top of the bottom plate. One side outer wall of the mixing barrel is bolted with evenly distributed one-way valves, and the inner wall of one side of the housing is connected with a rotating shaft through a bearing; the batching accuracy of this drawn protein batching device is poor and cannot meet the actual production requirements.

[0004] Chinese Patent CN115814695A discloses a mixing device and a mixing method for producing soy protein powder, including a frame and a mixing barrel arranged on the frame. The first feeding tank has a first discharge port, and a first valve and a first weight sensor are provided at the first discharge port. The first weight sensor controls the opening or closing of the first valve. The second feeding tank has a second discharge port, and a second valve and a second weight sensor are provided at the second discharge port; this mixing equipment has low mixing efficiency and poor mixing effect.

[0005] The raw materials of drawn protein are generally in a powdery structure. When the powdery raw materials are mixed with water, an emulsion structure will be formed, which will hinder the normal stirring and thus reduce the mixing efficiency.

[0006] At the same time, due to the different mixing degrees of the powdery raw materials and water at different positions inside the mixing device, and the raw materials are prone to caking, and the prior art cannot achieve fixed-point stirring and mixing of the raw materials at different positions, thus reducing the mixing effect and affecting the mixing uniformity. When the powdery raw materials and water are mixed to form an emulsion, the emulsion will flow to both sides under the action of thrust, thus reducing the fixed-point mixing effect.

[0007] Moreover, adding water to the inside of the powdery raw material easily causes uneven mixing of the powdery raw material and water, and ultimately affects the mixing effect. After mixing the powdery raw material and water in the mixing device for a long time, a large amount of powdery raw material and emulsion mixture are likely to adhere to the inside of the mixing device, not only reducing the mixing quality of the powdery raw material and water, but also affecting subsequent mixing. Summary of the Invention

[0008] In view of the above problems, the present invention provides a mixing device and a mixing method for producing drawn protein.

The bottoms of the driving motor and the liquid inlet pipe are both fixedly connected to the top of the support rod. A bearing seat is provided on the outer surface of the rotating cylinder. The outer surface of the bearing seat is fixedly connected to the inner wall of the housing.

[0017] Preferably, two liquid discharge holes are symmetrically opened at the top of the liquid inlet pipe. A plurality of docking holes are evenly opened inside the rotating cylinder. The liquid discharge holes are matched with the docking holes. The other end of the docking hole passes through the inside of the vertical rod. A plurality of flow holes are evenly opened on the opposite end faces of the vertical rods. One end of the flow hole is communicated with the docking hole.

[0018] Preferably, a plurality of elastic stoppers are evenly provided on the inner wall of the movable groove. The diameter of the elastic stopper matches the inner diameter of the movable groove. The ferromagnetic block has ferromagnetism and is attracted by magnetism. The other end of the elastic stopper is fixedly connected to the side wall of the ferromagnetic block. The left and right ends of the elastic movable plate are fixedly connected to the side wall of the fixed frame. The pressure sensor is used to detect the pressure value on the side wall of the elastic movable plate.

[0019] Preferably, sliding sheets are provided at the opposite ends of the ferromagnetic blocks at both ends. The sliding sheets are hermetically slidably connected to the inner wall of the sliding groove. The magnetic moving plate has magnetism, and a plurality of clamping grooves are evenly provided on the side wall of the magnetic moving plate. The inner wall of the clamping groove is hermetically slidably connected to the outer surface of the fixed frame.

[0020] Preferably, a plurality of installation grooves are evenly opened on one side of the vertical rod. A reciprocating motor is provided inside the installation groove. A lead screw is provided at the output end of the reciprocating motor. The other end of the lead screw is rotatably connected to the side wall of the corresponding vertical rod.

[0021] Preferably, two guiding holes are symmetrically formed on one side of the fixed frame away from the elastic movable plate.

The other end of each guiding hole communicates with a flexible hose, and the other end of the flexible hose is connected to the inlet end of a nozzle. The nozzle is of a U-shaped structure, and the outlet end of the nozzle matches the inner wall of the mixing chamber.

[0022] The present invention also provides a mixing method for a mixing device for producing drawn protein, comprising the following steps:

[0023] S1. Add powdery raw materials into the mixing chamber. The rotating cylinder rotates and drives a plurality of fixed frames to rotate through the vertical rods, and water is sprayed inside the nozzle to mix and stir the powdery raw materials;

[0024] S2. When the pressure value detected by the pressure sensor near the liquid inlet pipe increases and is greater than the pressure values detected by the pressure sensors at other positions, the magnetic movable plate moves to the end where the pressure value detected by the pressure sensor increases. The magnetic attraction force exerted by the magnetic movable plate on the ferromagnetic block increases, and the ferromagnetic block drives the elastic movable plate to move towards the magnetic movable plate end, and the elastic movable plate is inclined and sunken;

[0025] S3. When the magnetic movable plate moves towards the liquid inlet pipe, the magnetic attraction force exerted by the magnetic movable plate on the ferromagnetic block at the liquid inlet pipe end increases.

[0026] S4. After the mixing and stirring are completed, the rotating cylinder drives a plurality of fixed frames to rotate through the vertical rods. The magnetic movable plate reciprocates horizontally along one side of the fixed frame, and the water flow sprayed by the nozzle changes in pulses and cooperates with the fixed frame to scrape and wash the inner wall of the mixing chamber.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. By the mutual cooperation of components such as the housing assembly, the stirring assembly, and the mixing assembly, the present invention has high mixing efficiency, good mixing effect, meets the high-efficiency production requirements for drawn protein, has stronger adaptability, higher stability, simpler operation, is suitable for large-scale production operations, and ensures the quality of the subsequent drawn protein components.

[0029] 2. Through the mutual cooperation of components such as the vertical rods and the fixed frames, the present invention can also quickly stir and break the caked positions during the mixing of the powdery raw materials and water. The fixed-point breaking has a better mixing effect, and can also continuously aggregate and mix the raw materials inside the mixing chamber, with higher mixing and stirring quality.

[0030] 3. By setting the mutual cooperation of components such as the magnetic moving plate and the nozzle, when the magnetic moving plate moves on one side of the fixed frame, the water volume inside the nozzle is correspondingly adjusted, so as to ensure that the water volume sprayed out of the nozzle matches the raw material volume inside the mixing chamber, and improve the mixing uniformity and thoroughness of the powdery raw material and water.

[0031] 4. By setting the mutual cooperation of components such as the drain hole and the docking hole, after the mixing and stirring of the raw materials are completed, combined with the water sprayed by the nozzle and the scraping by the rotation of the fixed frame, the scraping and cleaning effect on the inner wall of the mixing chamber is improved, the cleaning range is larger, and the cleaning quality is higher.

A controller 105 is provided on one side of the leg 104, and the controller 105 electrically controls each electrical component. Two support rods 108 are symmetrically arranged at the top of the ring frame 103.

[0048] A plurality of blanking frames 106 are symmetrically arranged at the top of the outer shell 101. An electromagnetic valve 107 is arranged inside the blanking frame 106. The bottom of the blanking frame 106 passes through the outer shell 101 and is connected to the inside of the mixing chamber 102. When the electromagnetic valve 107 is opened, raw materials are added into the mixing chamber 102 along the blanking frame 106. A blanking hole 109 is opened at the bottom of the outer shell 101. The top of the blanking hole 109 is connected to the mixing chamber 102. A rotating plate 110 is rotatably connected inside the blanking hole 109 through a hinge rod. After the mixing of the raw materials is completed, the rotating plate 110 is opened, and the finished products inside the mixing chamber 102 are discharged along the blanking hole 109.

[0049] The stirring assembly 2 includes a rotating cylinder 201. The rotating cylinder 201 rotates at the axis center of the mixing chamber 102. An inner groove 205 is opened on one side of the rotating cylinder 201. A liquid inlet pipe 202 is arranged inside the inner groove 205. The liquid inlet pipe 202 is clamped and fixed with the inner groove 205. A plurality of vertical rods 208 are evenly arranged on the outer surface of the rotating cylinder 201. When the rotating cylinder 201 rotates, a plurality of vertical rods 208 are driven to rotate synchronously. A driving motor 203 is arranged at the axis center on one side of the outer shell 101. The output end of the driving motor 203 passes through the outer shell 101 and is fixedly connected to the side wall of the rotating cylinder 201. When the driving motor 203 is started, the rotating cylinder 201 is driven to rotate. The bottoms of the driving motor 203 and the liquid inlet pipe 202 are both fixedly connected to the top of the support rod 108. The support rod 108 plays a role in fixing and supporting the driving motor 203 and the liquid inlet pipe 202. A bearing seat 204 is arranged on the outer surface of the rotating cylinder 201. The outer surface of the bearing seat 204 is fixedly connected to the inner wall of the outer shell 101. The arrangement of the bearing seat 204 improves the safety and stability of the rotation of the rotating cylinder 201.

[0050] Two liquid discharge holes 206 are symmetrically opened at the top of the liquid inlet pipe 202. The water inside the liquid inlet pipe 202 can be discharged upward along the liquid discharge holes 206. A plurality of docking holes 207 are evenly opened inside the rotating cylinder 201. The liquid discharge holes 206 are matched with the docking holes 207. The docking holes 207 will rotate synchronously with the rotation of the rotating cylinder 201. When the docking holes 207 are located above the rotating cylinder 201, the docking holes 207 are connected to the liquid discharge holes 206. The water inside the liquid inlet pipe 202 is discharged upward along the liquid discharge holes 206 and the docking holes 207. The other end of the docking hole 207 passes through the inside of the vertical rod 208. A plurality of flow holes 209 are evenly opened on the end faces of the vertical rods 208 facing each other. One end of the flow hole 209 is connected to the docking hole 207. The other end of the flow hole 209 is slidably connected to a sliding groove 211. The water inside the docking hole 207 further flows along a plurality of flow holes 209 at the corresponding positions.

[0051] The mixing component 3 includes a fixed frame 301. One side of the fixed frame 301 is provided with a movable groove 302. An elastic movable plate 305 is hermetically and movably connected inside the movable groove 302. The elastic movable plate 305 can elastically move inside the movable groove 302. A plurality of elastic stoppers 303 are evenly arranged on the inner wall of the movable groove 302. The diameter of the elastic stopper 303 matches the inner diameter of the movable groove 302. The elastic stopper 303 elastically connects the movable groove 302 and the elastic movable plate 305. A plurality of ferromagnetic blocks 304 are evenly arranged on one side of the elastic movable plate 305 close to the fixed frame 301. On the basis of partitioning the movable groove 302, the elastic stopper 303 further improves the elastic reset performance of the elastic movable plate 305. The ferromagnetic block 304 has ferromagnetism and is attracted by magnetism. The other end of the elastic stopper 303 is fixedly connected to the side wall of the ferromagnetic block 304. The left and right ends of the elastic movable plate 305 are fixedly connected to the side wall of the fixed frame 301. Therefore, when the elastic stopper 303 moves, it will drive the elastic movable plate 305 to move synchronously. On the other side of the elastic movable plate 305 and at the end matching the ferromagnetic block 304, a plurality of pressure sensors 306 are provided. The pressure sensors 306 are used to detect the pressure value on the side wall of the elastic movable plate 305.

[0052] Sliding sheets 307 are provided at the ends of the ferromagnetic blocks 304 at both ends, facing away from each other. The sliding sheets 307 are hermetically and slidably connected to the inner wall of the sliding groove 211. The sliding sheets 307 block the sliding groove 211. That is, when the ferromagnetic blocks 304 at both ends move, they will drive the sliding sheets 307 to move synchronously. The blocking area of the sliding groove 211 by the sliding sheets 307 changes, and the amount of water entering the movable groove 302 inside the through hole 209 decreases.

[0053] A magnetic movable plate 308 is movably connected to the side of the fixed frame 301 away from the elastic movable plate 305. The magnetic movable plate 308 has magnetism, and a plurality of clamping grooves 309 are evenly arranged on the side wall of the magnetic movable plate 308. The inner wall of the clamping groove 309 is hermetically and slidably connected to the outer surface of the fixed frame 301. The arrangement of the clamping grooves 309 improves the sealing movement stability of the magnetic movable plate 308 on the outer surface of the fixed frame 301.

[0054] A plurality of installation grooves 210 are evenly opened on one side of the vertical rod 208. A reciprocating motor 310 is arranged inside the installation groove 210. The position of the reciprocating motor 310 is fixed and it can rotate forward and backward. The output end of the reciprocating motor 310 is provided with a lead screw 311. The other end of the lead screw 311 is rotatably connected to the side wall of the corresponding vertical rod 208. A plurality of threaded grooves 312 are penetrated and opened inside the magnetic movable plate 308. The outer surface of the lead screw 311 is threadedly connected to the inner wall of the threaded groove 312. When the reciprocating motor 310 rotates forward, the reciprocating motor 310 drives the lead screw 311 to rotate forward. The lead screw 311 is threadedly connected to the threaded groove 312 and drives the magnetic movable plate 308 to move away from the end of the reciprocating motor 310.

[0055] On one side of the fixed frame 301 away from the elastic movable plate 305, two guiding holes 315 are symmetrically formed. The guiding holes 315 are located on the side close to the sliding groove 211. The water entering the inner part of the movable groove 302 along the circulation hole 209 can continue to flow along the guiding holes 315. The other end of the guiding hole 315 is communicated with a hose 313, and the other end of the hose 313 is connected with the inlet end of a nozzle 314. A plurality of nozzles 314 are evenly formed on both sides of the magnetic movable plate 308. Then, the water in the guiding hole 315 enters the nozzle 314 along the hose 313 for spraying. The nozzle 314 is of a U-shaped structure, and the outlet end of the nozzle 314 matches the inner wall of the mixing cavity 102. When the magnetic movable plate 308 moves, the nozzle 314 is synchronously driven to move, and the water spraying amount of the nozzle 314 on the inner wall of the mixing cavity 102 changes, further ensuring the mixing effect of the raw materials inside the mixing cavity 102 and the flushing and cleaning quality of the inner wall of the mixing cavity 102.

[0056] The raw material of the drawn protein is generally in a powdery structure, and the powdery structure is mixed with water and then subjected to subsequent extrusion molding. Since an emulsion structure will be formed when the powdery raw material is mixed with water, the emulsion structure will hinder normal stirring, thereby reducing the mixing efficiency. At the same time, due to the different mixing degrees of the powdery raw material and water at different positions inside the mixing cavity 102, and there are lumping phenomena in the raw material, and the prior art cannot achieve fixed-point stirring and mixing at different positions, thus reducing the mixing effect and affecting the mixing uniformity. At the same time, when the powdery raw material and water inside the mixing cavity 102 are mixed to form an emulsion, the emulsion will flow to both sides under the action of the thrust force, thereby reducing the fixed-point pushing and mixing effect of the magnetic movable plate 308 on the emulsion. And the prior art cannot uniformly add water inside the mixing cavity 102, thus easily causing uneven mixing of the powdery raw material and water, and ultimately affecting the mixing effect. The magnetic movable plate 308 moves inside the mixing cavity 102 and continuously changes the stirring position, so it directly affects the uniformity and synchronism of water addition. And when the powdery raw material and water are mixed inside the mixing cavity 102 for a long time, a large amount of powdery raw material and emulsion mixture are easily attached to the inside of the mixing cavity 102, not only reducing the mixing quality of the powdery raw material and water, but also affecting the subsequent mixing.

[0057] During use, different raw materials are first added into the feeding frame 106. When it is necessary to mix the raw materials, the controller 105 opens the solenoid valve 107. The powdery raw materials in multiple feeding frames 106 enter the mixing chamber 102 along the feeding frame 106, and the addition amount of different powdery raw materials is correspondingly controlled to ensure the mixing quality of the subsequent powdery raw materials and water. The height of the powdery raw materials in the mixing chamber 102 does not exceed the height value of the rotating cylinder 201. After the feeding is completed, the controller 105 controls the solenoid valve 107 to close, and at the same time starts the driving motor 203. The driving motor 203 drives the rotating cylinder 201 to rotate, the rotating cylinder 201 drives multiple vertical rods 208 to rotate, the vertical rods 208 drive multiple fixed frames 301 to rotate, and the fixed frames 301 synchronously drive the magnetic moving plate 308 to rotate, thereby realizing the mixing of the powdery raw materials in the mixing chamber 102.

[0058] After that, water is introduced into the liquid inlet pipe 202. The water in the liquid inlet pipe 202 reaches the drain hole 206 end. When the rotating cylinder 201 drives some of the vertical rods 208 to rotate to the vertically upward state, the docking hole 207 coincides with the drain hole 206. The water in the liquid inlet pipe 202 enters the docking hole 207 upward along the drain hole 206. At the same time, since the ferromagnetic blocks 304 on both sides drive the sliding piece 307 and do not block the sliding groove 211, the water in the docking hole 207 enters the movable grooves 302 at both ends along multiple through holes 209. The water in the movable grooves 302 further enters the nozzle 314 along the guiding hole 315 and the hose 313, and finally discharges to both sides along the nozzle 314, thereby realizing the water addition and mixing process of the powdery raw materials in the mixing chamber 102. At the same time, since the docking hole 207 is only connected to the drain hole 206 when the vertical rod 208 is vertically upward, when the vertical rod 208 drives multiple nozzles 314 to spray, the water is directly sprayed above the powdery raw materials, thereby improving the mixing uniformity of the powdery raw materials and water, and avoiding the excessive scouring force of the nozzle 314 directly spraying water in the powdery raw materials and affecting the subsequent mixing effect of the powdery raw materials.

[0059] As the rotating cylinder 201 drives multiple vertical rods 208 and fixed frames 301 to rotate, the elastic movable plate 305 at the end of the fixed frame 301 collides with the raw materials in the mixing chamber 102 by extrusion. The pressure values detected by multiple pressure sensors 306, and with the continuous spraying of water by the nozzle 314, the mixing degree of the powdery raw materials and water in the mixing chamber 102 continuously increases, the pressure values detected by the pressure sensors 306 continuously increase, and the pressure values detected by multiple pressure sensors 306 at the end of the same fixed frame 301 are the same, indicating that the mixing degree of the raw materials at this position in the mixing chamber 102 is the same.

[0060] When the pressure value detected by the pressure sensor 306 at a certain position increases and is greater than the pressure values detected by the pressure sensors 306 at other positions, it indicates that there is caking inside the raw materials at this position. Then, the controller 105 controls the reciprocating motor 310 at the corresponding position to start. The reciprocating motor 310 drives the lead screw 311 to rotate. The lead screw 311 is in threaded rotational connection with the threaded groove 312 and drives the magnetic moving plate 308 to move. The magnetic moving plate 308 is engaged and moved with multiple fixed frames 301 through the engaging groove 309 and realizes moving on one side of the fixed frame 301. When the magnetic moving plate 308 moves to the end where the pressure value detected by the pressure sensor 306 increases, the magnetic moving plate 308 cooperates with the rotation of the fixed frame 301 to achieve vertex collision and crushing of the caking position, further improving the stirring and mixing effect of the raw materials inside the mixing chamber 102, with stronger adaptability and higher positioning accuracy, meeting the actual raw material mixing requirements.

[0061] Meanwhile, when the magnetic moving plate 308 moves along one side of the fixed frame 301, the magnetic attraction force of the magnetic moving plate 308 on multiple ferromagnetic blocks 304 changes. That is, when the magnetic moving plate 308 reaches the end where the pressure value detected by the pressure sensor 306 increases, the magnetic attraction force exerted by the magnetic moving plate 308 on the ferromagnetic block 304 is the largest. Under the action of this magnetic attraction force, the ferromagnetic block 304 presses the elastic stop block 303 and moves towards the end close to the fixed frame 301 to the maximum value. The ferromagnetic block 304 correspondingly drives the elastic movable plate 305 to move towards the end close to the fixed frame 301 to the maximum value at this position, and the distance between the elastic movable plate 305 and the fixed frame 301 is the smallest.

[0062] As the distance between the ferromagnetic blocks 304 and the magnetic moving plate 308 on both sides of the position where the pressure value detected by the pressure sensor 306 increases continuously increases, the magnetic suction force exerted by the magnetic moving plate 308 on the ferromagnetic blocks 304 on both sides continuously decreases. Then, along the position where the pressure value detected by the pressure sensor 306 increases, the ferromagnetic blocks 304 squeeze the elastic stoppers 303, and the distance between the ferromagnetic blocks 304 and the fixed frame 301 continuously increases. The ferromagnetic blocks 304 drive the distance between the elastic movable plates 305 at the corresponding positions and the fixed frame 301 to continuously increase. Therefore, the elastic movable plates 305 are tilted and sunken under the driving action of the plurality of ferromagnetic blocks 304, and the distance between the ends of the two vertical rods 208 and the end where the pressure value detected by the pressure sensor 306 increases and the fixed frame 301 decreases, that is, depressions continuously occur from the ends of the two vertical rods 208 to the end where the pressure value detected by the pressure sensor 306 increases. When the two vertical rods 208 drive the plurality of fixed frames 301 to continuously rotate, the fixed frames 301 rotate synchronously with the elastic movable plates 305. The elastic movable plates 305 cooperate with their own sunken structures to continuously gather the raw materials inside the mixing cavity 102 towards the sunken areas. Then, when the fixed frames 301 drive the magnetic moving plates 308 to continuously rotate, the collision and mixing effect on the raw materials is more concentrated, further realizing the continuous gathering and mixing of the raw materials inside the mixing cavity 102, improving the mixing efficiency, and ensuring the mixing effect.

[0063] When the magnetic moving plate 308 moves on one side of the fixed frame 301, the magnetic moving plate 308 correspondingly drives a plurality of nozzles 314 to move. Moreover, the magnetic suction force exerted by the magnetic moving plate 308 and the ferromagnetic blocks 304 at both ends correspondingly changes. The ferromagnetic blocks 304 at both ends drive the sliding piece 307 to move along the sliding groove 211. The blocking area of the sliding piece 307 for the flow hole 209 changes, the content of the water entering the internal activity groove 302 along the flow hole 209 in the docking hole 207 changes, the amount of water reaching the inside of the nozzle 314 along the hose 313 inside the activity groove 302 changes, and the amount of water sprayed by the nozzle 314 changes. Thereby, it is ensured that the water can be evenly sprayed inside the mixing cavity 102, and the mixing quality of the raw materials and water inside the mixing cavity 102 is correspondingly ensured.

[0064] Specifically, when the magnetic moving plate 308 moves along one side of the fixed frame 301 towards the end near the liquid inlet pipe 202, the distance between the nozzle 314 at the end of the magnetic moving plate 308 and the inner wall of the mixing chamber 102 near the end of the liquid inlet pipe 202 decreases. The magnetic attraction force exerted by the magnetic moving plate 308 on the ferromagnetic block 304 at the end of the liquid inlet pipe 202 increases, and the ferromagnetic block 304 moves towards the end near the fixed frame 301. At this time, the ferromagnetic block 304 not only drives the elastic movable plate 305 to move towards the end near the fixed frame 301 and a depression appears there, but also drives the sliding piece 307 to move inside the sliding groove 211. The blocking area of the sliding piece 307 for the sliding groove 211 increases, and the amount of water in the docking hole 207 reaching the end of the sliding groove 211 along the flow hole 209 and entering the inside of the movable groove 302 decreases. The amount of water finally entering the inside of the nozzle 314 along the guiding hole 315 and the hose 313 inside the movable groove 302 decreases, and the amount of water sprayed out by the nozzle 314 towards the end near the liquid inlet pipe 202 decreases.

[0065] Similarly, since the magnetic moving plate 308 moves away from the end of the driving motor 203, the magnetic attraction force exerted by the magnetic moving plate 308 on the ferromagnetic block 304 on this side decreases. Under the elastic force of the elastic stopper 303, the ferromagnetic block 304 is driven to move away from the end of the fixed frame 301. The ferromagnetic block 304 correspondingly drives the sliding piece 307 to move. The blocking area of the sliding piece 307 for the sliding groove 211 decreases, and the content of water in the docking hole 207 entering the inside of the movable groove 302 along the flow hole 209 and the sliding groove 211 increases. The amount of water entering the inside of the nozzle 314 through the guiding hole 315 and the hose 313 in the movable groove 302 increases, and the water flow rate sprayed out by the nozzle 314 towards the end near the driving motor 203 increases. Further, the spraying amount of the nozzle 314 is made to match the moving position of the magnetic moving plate 308, thereby improving the mixing uniformity and thoroughness of the water sprayed out by the nozzle 314 and the powdery raw materials inside the mixing chamber 102.

[0066] When the pressure values detected by multiple pressure sensors 306 reach the set pressure preset value, it indicates that the powdery raw materials and water inside the mixing chamber 102 have been mixed. Then, the rotating plate 110 is opened, the rotating cylinder 201 rotates and drives the fixed frame 301 to continuously rotate through the vertical rod 208. The fixed frame 301 continuously squeezes and scrapes against the inner wall of the mixing chamber 102, so that the raw materials inside the mixing chamber 102 can be evenly and thoroughly discharged along the blanking hole 109, further improving the discharging thoroughness and stability of the raw materials inside the mixing chamber 102.

[0067] After that, the controller 105 controls the reciprocating motor 310 to rotate forward and backward continuously. The reciprocating motor 310 drives the lead screw 311 to rotate reciprocally. The lead screw 311 is in threaded fit with the threaded groove 312 and drives the magnetic moving plate 308 to move reciprocally horizontally along the fixed frame 301. The magnetic moving plate 308 synchronously drives a plurality of nozzles 314 to move reciprocally. At the same time, in cooperation with the rotating cylinder 201, the vertical rod 208 drives a plurality of fixed frames 301 to rotate. The fixed frame 301 drives the magnetic moving plate 308 to rotate. And when the vertical rod 208 rotates to the upward direction, the nozzles 314 spray out water, and in cooperation with the continuous misaligned connection of the liquid discharge hole 206 and the docking hole 207, the nozzles 314 spray out pulsed water flow. This pulsed water flow can further scour and incline the inner wall of the mixing chamber 102, and continuously flow downward to the end of the blanking hole 109 under the action of the gravity of the water flow itself. Under the scraping effect of the fixed frame 301, the impurities on the inner wall of the mixing chamber 102 are driven to continuously discharge along the blanking hole 109, further improving the scouring and cleaning effect of the water sprayed by the nozzles 314 on the inner wall of the mixing chamber 102, and the cleaning range is larger.

[0068] After the inside of the mixing chamber 102 is cleaned, the rotating plate 110 is closed, and the solenoid valve 107 is reopened. The powdery raw materials inside the plurality of blanking frames 106 enter the inside of the mixing chamber 102, and the above process is repeated to realize the mixing and stirring of the subsequent pulled protein raw materials.

[0069] This mixing device has high mixing efficiency and good mixing effect, meets the high-efficiency production requirements of pulled protein, has stronger adaptability, higher stability, simpler operation, is suitable for mass production operations, and ensures the quality of the subsequent pulled protein components; at the same time, during the mixing process of the powdery raw materials and water, it can also realize the rapid stirring and crushing of the caking positions correspondingly, and the fixed-point crushing mixing effect is better, and it can also realize the continuous aggregation and mixing of the raw materials inside the mixing chamber 102, and the mixing and stirring quality is higher; and when the magnetic moving plate 308 moves on one side of the fixed frame 301, the water volume inside the nozzle 314 is correspondingly adjusted, so as to ensure that the water volume sprayed out inside the nozzle 314 matches the amount of raw materials inside the mixing chamber 102, improving the mixing uniformity and thoroughness of the powdery raw materials and water; when the mixing and stirring of the raw materials are completed, in cooperation with the water sprayed by the nozzles 314 and the rotation and scraping of the fixed frame 301, the scraping and cleaning effect on the inner wall of the mixing chamber 102 is improved, the cleaning range is larger, and the cleaning quality is higher.

[0073] S2. When the pressure value detected by the pressure sensor 306 on the side close to the liquid inlet pipe 202 increases and is greater than the pressure values detected by the pressure sensors 306 at other positions, the magnetic moving plate 308 moves to the end where the pressure value detected by the pressure sensor 306 increases. The magnetic attraction force exerted by the magnetic moving plate 308 on the ferromagnetic block 304 increases, and the ferromagnetic block 304 drives the elastic movable plate 305 to move towards the magnetic moving plate 308, and the elastic movable plate 305 is tilted and recessed.

[0074] S3. When the magnetic moving plate 308 moves closer to the liquid inlet pipe 202, the magnetic attraction force exerted by the magnetic moving plate 308 on the ferromagnetic block 304 at the end of the liquid inlet pipe 202 increases. The ferromagnetic block 304 drives the sliding piece 307 to increase the clogging area of the sliding groove 211, and the water flow rate entering the nozzle 314 along the sliding groove 211 decreases.

[0075] S4. When the mixing and stirring are completed, the rotating cylinder 201 drives the plurality of fixed frames 301 to rotate through the vertical rod 208. The magnetic moving plate 308 reciprocates horizontally along one side of the fixed frame 301, and the water flow pulse ejected from the nozzle 314 changes and cooperates with the fixed frame 301 to scrape and wash the inner wall of the mixing chamber 102.
