Description

Technical Field

[0001] The invention relates to the technical field of soybean fibrous protein production, and in particular to a cooling type grinding device for soybean fibrous protein raw material and a use method thereof. Background Art

[0002] Soy protein is a food rich in plant protein, which is made from processed soybeans. The following is a common production process of soy protein, which is divided into the steps of soybean soaking, pulping, dehydration, coagulation, drawing, dehydration and drying. Before soybean grinding, first peel the soybeans and soak them in clean water to soften the soybean particles, then put the soaked soybeans into the grinder, add appropriate amount of clean water, stir and grind until the soybean particles are completely broken and form a slurry.

[0003] The Chinese invention patent with application number 202310110965.5 proposes an air-cooled raw material grinder for the production and processing of nutritious food. The grinder includes a grinding chamber, a mounting block, and a rack. The grinding chamber is equipped with a protective cover. A fixing plate is fixed on the protective cover, and the rack is rotatably connected to the protective cover. The mounting block has a mounting chamber, and a first gear and a second gear are arranged in the mounting chamber for unidirectional rotation, and the first gear and the second gear are both matched with the rack. When the protective cover needs to be closed, it is only necessary to rotate the mounting frame and then push the protective cover so that the protective cover can seal and cover the grinding chamber. Under the limitation of the first gear and the second gear, the rack cannot fall out of the mounting chamber, so as to realize the fixed connection between the protective cover and the grinding chamber. When the protective cover needs to be opened, it is only necessary to rotate the circular plate so that the first gear, the second gear, and the rack rotate 180 degrees around the axis of the circular plate so that the rack can fall out of the mounting chamber, and then the protective cover can be opened.

[0004] However, the grinding efficiency of the prior art is low when applied to the production and grinding of soy fibrous protein. Since the soybeans need to be soaked before grinding, the wet soybean raw materials are easily stuck between the teeth of the rack, resulting in poor grinding effect. In addition, the equipment lacks a stirring component. The production and grinding of soy fibrous protein requires the addition of water and then grinding into a slurry. This step requires a stirring component to stir and mix. During stirring, the soybean particles are also prone to rotate synchronously with the liquid, resulting in uneven grinding and mixing. In addition, when the soybeans are ground and discharged, the soybean slurry is also prone to stick to the wall and solidify, affecting the quality of the subsequent soy fibrous protein.

[0005] Therefore, it is necessary to solve the above problems by a cooling grinding device for soybean protein raw materials. Summary of the invention

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] In order to solve the problems in the prior art that wet soybean raw materials are easily stuck between the teeth of the rack during grinding, resulting in poor grinding effect, lack of stirring structure to assist in grinding the soybean slurry into a slurry, uneven stirring and grinding, and the soybean slurry is easily stuck to the wall and solidified when discharged, embodiment 1 is proposed.

[0024] Embodiment 1: like Figures 1 to 7 As shown, the present invention discloses a cooling type grinding device for soybean protein raw material, comprising a box assembly 1, a power assembly 2 and a feed pipe 3 are fixedly installed on the top of the box assembly 1, a discharge cavity is fixedly arranged at the bottom of the box assembly 1, a discharge port 9 is arranged on one side of the discharge cavity, a grinding assembly 4 is arranged inside the box assembly 1, stirring assemblies 5 are evenly arranged on the sides of the grinding assembly 4, reset assemblies 6 are symmetrically arranged on both sides of the stirring assembly 5, buffer assemblies 7 are evenly arranged inside the grinding assembly 4, and a blocking assembly 8 is arranged in the discharge cavity.

[0025] By setting the grinding component 4 and controlling the grinding component 4 to reciprocate and rise and fall, the soybeans can be ground to avoid the problem of material jamming. At the same time, by setting the stirring component 5, the power component 2 is controlled to drive the grinding component 4 and the stirring component 5 to rotate, so as to achieve the stirring of the soybean slurry and the cleaning during feeding, thereby ensuring the uniformity of the soybean slurry and avoiding waste. By setting the reset component 6, the stirring component 5 can be reciprocated in the vertical direction to break up the soybean raw materials that rotate synchronously with the inertia of the water flow.

[0026] In the common soybean raw material grinding process, the grinding roller directly contacts the soybean raw material for grinding. The soybean raw material after grinding is easy to stick to the grinding roller, causing material jamming, which leads to poor grinding effect of the grinding roller and uneven mixing of the soybean raw material and water.

[0027] In order to solve the above technical problems, in this embodiment, the grinding filter 402 is provided to squeeze and grind the soybeans while separating the coarse and fine soybean materials. Figure 3-Figure 4As shown, the grinding assembly 4 includes a grinding cylinder 401, and an annular groove is provided at the bottom of the grinding cylinder 401. The height of the annular groove is higher than the height of the grinding filter 402, and the grinding filter 402 can slide and rise and fall along the side wall of the annular groove. The bottom of the grinding cylinder 401 is slidably connected with the grinding filter 402, and a through hole 403 is provided on the bottom surface of the grinding cylinder 401, and a sealing plate 404 is rotatably connected in the through hole 403; a limit plate 405 is movably provided in the through hole 403, and the limit plate 405 is configured to be retractable. During the stirring and grinding process, the limit plate 405 is in an extended and fixed state to prevent the sealing plate 404 from rotating downward. During the subsequent discharge process, the limit plate 405 is in a retracted state, and the sealing plate 404 rotates downward to open the through hole 403, so as to facilitate the discharge of the slurry in the grinding cylinder 401. The limit plate 405 is arranged below the sealing plate 404. A cross 406 is fixedly arranged on the top of the grinding cylinder 401. A lifting rod 407 is fixedly arranged at the center of the top surface of the cross 406. The output end of the lifting rod 407 reciprocates and extends to drive the grinding cylinder 401 to reciprocate and lift. During the lifting and lowering process of the grinding cylinder 401, the grinding filter 402 is driven to lift and lower at the bottom of the grinding cylinder 401. The inside of the side wall of the grinding cylinder 401 is evenly provided with accommodating cavities, and a buffer assembly 7 is arranged in the accommodating cavity. The buffer assembly 7 includes a traction rod 701. The traction rod 701 is fixedly connected to the top of the grinding filter 402. The end of the traction rod 701 away from the grinding filter 402 is fixedly connected to the extrusion plate 702; the lifting and lowering of the extrusion plate 702 will generate suction force and extrusion force in the telescopic tube 704. The end of the extrusion plate 702 away from the traction rod 701 is fixedly connected to the buffer spring 703 and the telescopic tube 704. The buffer spring 70 The buffer spring 703 is arranged inside the telescopic tube 704. When the grinding cylinder 401 does not move up or down, the buffer spring 703 is in the initial compression state, forcing the grinding filter 402 to press against the bottom surface of the grinding cylinder 401. When the grinding cylinder 401 moves up or down, the grinding filter 402 moves up or down accordingly due to inertia. When the grinding filter 402 rises, the squeezing plate 702 is driven by the traction rod 701 to compress the buffer spring 703 for the second time. When the grinding filter 402 descends, the buffer spring 703 returns to the initial compression state. A hard tube 705 is fixedly provided at one end of the telescopic tube 704 away from the extrusion plate 702. The hard tube 705 is fixedly provided at the top of the accommodating cavity. A branch tube 706 is fixedly connected to the side of the hard tube 705. One end of the branch tube 706 is fixedly provided at the bottom of the side of the grinding cylinder 401. The branch tube 706 is connected to the inside of the hard tube 705. When the grinding cylinder 401 sinks into the soybean slurry and rises and falls, the descent of the extrusion plate 702 will cause the liquid to be sucked into the telescopic tube 704. The rise of the extrusion plate 702 will press the liquid sucked into the telescopic tube 704 out of the branch tube 706, forming a water flow with a certain impact force, which impacts the grinding filter 402 to prevent the filter from being blocked by the soybean raw material.

[0028] In the existing soy filament protein production process, before the soybeans are ground, the dried soybeans are first soaked in water to allow the soybeans to absorb water, swell and soften. After the soaking is completed, the soaked soybeans and an appropriate amount of water are put into a grinding device and ground into a slurry.

[0029] In this embodiment, the soaked soybeans are input into the mixing barrel 101 through the feed pipe 3, and then water is added. Then, the output end of the lifting rod 407 is controlled to extend, and the grinding cylinder 401 is driven to descend through the cross 406, so that the grinding cylinder 401 descends below the liquid surface. At the same time, the power component 2 is controlled to drive the lifting rod 407 to rotate, thereby driving the grinding cylinder 401 and the stirring component 5 to rotate.

[0030] During the rotation of the grinding cylinder 401, the grinding cylinder 401 is the center of the vortex formed by the rotation of the soybean liquid. Since the soybeans have not been ground yet, the overall particles are relatively large and are easy to sink and gather at the bottom of the grinding cylinder 401. At this time, the output end of the lifting rod 407 is controlled to perform a short and rapid extension and contraction, driving the grinding cylinder 401 to repeatedly rise and fall inside the soybean liquid. When the grinding cylinder 401 descends, the liquid itself will produce upward resistance, causing the grinding filter 402 to move vertically upward along the side wall of the annular groove until the top surface of the grinding filter 402 fits the top of the annular groove, and space appears under the grinding filter 402. At the same time, the resistance of the liquid will cause the sealing plate 404 to rotate upward to open the through hole 403. Subsequently, the upper surface of the grinding cylinder 401 At the moment of rising, the water flow below the grinding cylinder 401 will rise with the grinding cylinder 401 due to inertia, thereby driving the soybean particles at the bottom to enter the space below the grinding filter 402 from the through hole 403. As the rise continues, the liquid itself will produce downward resistance, forcing the sealing plate 404 to rotate downward, closing the through hole 403, and the grinding filter 402 will drop vertically. The resistance of the liquid and the reset of the buffer spring 703 work together to make the grinding filter 402 quickly reset and squeeze and crush the soybean particles below the grinding filter 402. When the grinding cylinder 401 descends for the second time, the fine particles after squeezing and crushing pass through the grinding filter 402 due to the resistance of the water flow, and are mixed into the liquid to complete the grinding and crushing of the soybean particles.

[0031] During this process, the grinding filter 402 drives the squeezing plate 702 to rise through the traction rod 701, compressing the telescopic tube 704 and the buffer spring 703, so that the liquid inside the telescopic tube 704 is ejected from the bottom of the side of the grinding cylinder 401 through the end of the branch pipe 706, and impacts the grinding filter 402, thereby preventing the soybean raw material lumps from adhering to the grinding filter 402 and blocking the grinding filter 402 during the repeated grinding of the grinding filter 402; it can also disperse the soybean raw material lumps that have separated from the grinding filter 402; at the same time, it can also impact and gather the soybean raw material entering the space below the grinding filter 402 to the center range of the grinding filter 402, assisting the grinding filter 402 to better extrude and crush the soybean particles.

[0032] The soybean particles are crushed and ground by setting a grinding filter 402, and the soybean fine material is quickly separated and mixed with the liquid, while the soybean coarse material is left under the grinding filter 402 waiting for the next extrusion, crushing and grinding; according to the resistance of the liquid to the grinding filter 402 in different directions during the lifting process, the auxiliary grinding filter 402 rises or falls along the inner wall of the grinding cylinder 401, and the grinding cylinder 401 rises to create a space for accommodating the soybean particles, and the grinding cylinder 401 descends to grind and squeeze the soybean particles entering the space, thereby avoiding the situation where the raw materials are easily stuck when using the grinding roller to crush.

[0033] During the grinding process of soybeans, it is also necessary to stir them to make the slurry evenly distributed and speed up the process of grinding the soybean raw materials into slurry. When the slurry is stirred, the edge of the liquid will be higher than the liquid level in the static state. During the subsequent discharge, the slurry level will suddenly drop, which will cause part of the soybean slurry to remain on the inner wall of the mixing barrel 101 that is higher than the static liquid level. At this time, the residual soybean slurry needs to be scraped off. In this embodiment, a stirring component 5 is provided to stir and scrape the soybean slurry. Figure 5As shown, the stirring assembly 5 includes a sleeve 506, one end of the sleeve 506 is fixedly connected to the stirring rod 501, and the other end is slidably connected to the telescopic rod 504, the telescopic rod 504 slides along the inner wall of the sleeve 506, a telescopic spring 503 is fixedly arranged between the telescopic rod 504 and the stirring rod 501, one end of the telescopic rod 504 is hinged to an arc plate 507, and a torsion spring is arranged at the hinge of the telescopic rod 504 and the arc plate 507, so as to facilitate the subsequent scraping of the inclined surface of the mixing barrel 101; the stirring rod 501 is close to the telescopic spring 503. The end of the mixing drum 101 is fixed with an electromagnet 502. When the electromagnet 502 is not energized, the telescopic spring 503 is in a relaxed state, and the arc plate 507 is separated from the inner wall of the mixing drum 101. When the electromagnet 502 is energized, an attraction is generated on the permanent magnet 505, so that the telescopic spring 503 is in a compressed state. At the same time, the telescopic rod 504 is driven to slide along the inner wall of the sleeve 506 toward the stirring rod 501, so that the end of the telescopic rod 504 fits with the end of the stirring rod 501, temporarily controlling the arc plate 507 to stay away from the mixing drum 101. 1, a permanent magnet 505 is fixedly arranged at one end of the telescopic rod 504 close to the telescopic spring 503, a fixing frame 508 is hingedly connected at one end of the stirring rod 501 away from the telescopic spring 503, and the fixing frame 508 is arranged on the side of the grinding cylinder 401; hinge points are arranged at both ends of the fixing frame 508, and a reset assembly 6 is hinged on the hinge point, and the reset assembly 6 includes a reset rod 601 rotatably connected to the hinge point, the reset rod 601 is symmetrically arranged on both sides of the stirring rod 501, and the inner cavity of the reset rod 601 is slidably connected to the telescopic rod 504. The retractable support rod 602 is fixedly connected to a return spring 603 at the end of the inner cavity of the reset rod 601. The end of the return spring 603 away from the retractable support rod 602 is fixedly connected to the end of the inner cavity of the reset rod 601. When the grinding component 4 reciprocates and rises and falls, the stirring rod 501 is driven to swing back and forth with the hinge point with the fixed frame 508 as the center. During the swinging process, the return spring 603 limits the swinging range of the stirring rod 501 to prevent the stirring rod 501 from swinging too much and throwing the soybean slurry out of the mixing barrel 101.

[0034] In this embodiment, the grinding cylinder 401 rotates, which drives the stirring assembly 5 to stir the soybean slurry. In the process of the grinding cylinder 401 reciprocating and ascending and descending, the resistance of the liquid causes the stirring rod 501 to keep reciprocating while rotating with the grinding cylinder 401, thereby breaking up the soybeans accumulated under the feeding pipe 3. At the same time, the electromagnet 502 is energized to generate an attraction force on the permanent magnet 505, thereby attracting the telescopic rod 504 to approach the stirring rod 501, until the end of the telescopic rod 504 fits with the end of the stirring rod 501, so that the arc plate 507 is away from the inner wall of the mixing barrel 101, forming a state of a stirring blade with a fixed length, and fully stirring the soybean slurry.

[0035] After the stirring is completed, the discharge port 9 is opened by controlling the sealing component 8 to discharge the soybean slurry. The soybean slurry will remain on the inner wall of the mixing barrel 101. At this time, the output end of the lifting rod 407 is controlled to retract, driving the grinding cylinder 401 to separate from the soybean slurry and rise to above the soybean slurry liquid level inside the mixing barrel 101. At this time, since the through hole 403 is in a closed state, the grinding cylinder 401 forms a box shape, and soybean slurry will exist inside. The limit plate 405 is controlled to be retracted, and the sealing plate 404 is rotated downward to open the through hole 403, and the soybean slurry is discharged from the through hole 403. Then, the output end of the lifting rod 407 is controlled to slowly extend, driving the grinding cylinder 401 and the stirring assembly 5 to slowly descend. At the same time, the electromagnet 502 is controlled to be powered off, losing the attraction to the permanent magnet 505. The telescopic spring 503 drives the telescopic rod 504 away from the stirring rod 501 and resets instantly. Since the grinding cylinder 401 is still in the process of continuous rotation, the telescopic rod 504 will generate centrifugal force. Under the support of the centrifugal force, the telescopic rod 504 will continue to move away from the stirring rod 501 after a short reset. At this time, the telescopic spring 503 is in a stretched state. When the telescopic spring 503 is detected, When the stretching amount remains stable and no longer increases, it can be determined that the current arc plate 507 is already close to the inner wall of the mixing barrel 101, and the power assembly 2 is controlled to drive the grinding cylinder 401 to accelerate the rotation speed. The centrifugal force will cause the soybean slurry remaining on the grinding cylinder 401 to be thrown onto the inner wall of the mixing barrel 101, and then the arc plate 507 rotates and scrapes it off, thereby completing the cleaning of the soybean slurry remaining above the static liquid surface on the inner wall of the mixing barrel 101, preventing the soybean slurry from solidifying above the static liquid surface in the mixing barrel 101, causing the subsequent soybean slurry to fall into the solidified blocks, affecting the quality of the soybean protein.

[0036] By setting the telescopic rod 504 and the telescopic spring 503, the telescopic spring 503 assists the telescopic rod 504 in extending and retracting, thereby driving the arc plate 507 to change the distance from the inner wall of the mixing barrel 101, so that the telescopic rod 504 is maintained at a fixed length for stirring during stirring, thereby ensuring the uniformity of the soybean slurry, and the telescopic rod 504 drives the arc plate 507 to stick to the inner wall of the mixing barrel 101 during cleaning, thereby ensuring that the soybean slurry hanging on the inner wall of the mixing barrel 101 above the static liquid level can be cleaned.

[0037] like Figure 6-Figure 7As shown, the box assembly 1 includes a mixing barrel 101, a support rod 102 is evenly arranged on the top of the mixing barrel 101, a support plate 103 is fixedly arranged on the top of the support rod 102, a fixed ring plate 106 is fixedly arranged on the outside of the mixing barrel 101, and a support column 107 is evenly arranged on the bottom of the fixed ring plate 106, a cooling chamber 104 is fixedly arranged on the outside of the mixing barrel 101, and a refrigeration pipe 105 is evenly arranged inside the cooling chamber 104. The refrigeration pipe 105 is used to maintain the mixing barrel 101 within a certain temperature range to prevent the temperature of the component from rising due to repeated lifting and rapid rotation of the grinding cylinder 401, which leads to an increase in the temperature of the soybean slurry; The force assembly 2 includes a transmission rod 201, which is rotatably connected to the support plate 103, on which a motor 205 is fixedly arranged, the output end of the motor 205 passes through the support plate 103 and is fixedly connected to a driving wheel 204, a driven wheel 202 is fixedly arranged on the transmission rod 201, a transmission belt 203 is wound around the circumference of the driven wheel 202, and the transmission belt 203 is arranged around the driven wheel 202 and the driving wheel 204 in sequence; the motor 205 is started, driving the driving wheel 204 to rotate, and the driving wheel 204 drives the driven wheel 202 to rotate through the transmission belt 203, thereby driving the transmission rod 201 to rotate, and then driving the grinding assembly 4 to rotate. The plugging assembly 8 includes a hydraulic cylinder 801 arranged at the bottom of the discharge chamber, the output end of the hydraulic cylinder 801 passes through the discharge chamber and extends into the interior of the discharge chamber, and the output end of the hydraulic cylinder 801 is fixedly connected to a plugging block 802. During stirring and grinding, the output end of the hydraulic cylinder 801 is controlled to remain extended, driving the top surface of the blocking block 802 to be flush with the inner bottom surface of the mixing barrel 101. When discharging is required, the output end of the hydraulic cylinder 801 is controlled to retract, driving the blocking block 802 to descend along the discharge cavity until the top surface of the blocking block 802 is flush with the lowest point of the discharge port 9, and the soybean slurry is discharged.

[0038] The working principle of the present invention is as follows: first, the soaked soybeans are fed into the mixing barrel 101 through the feed pipe 3, and then a proper amount of water is added according to production requirements.

[0039] Secondly, for grinding, the output end of the lifting rod 407 is controlled to extend, and the grinding cylinder 401 is driven to descend through the cross 406, so that the grinding cylinder 401 descends below the liquid level. At the same time, the motor 205 is started to drive the driving wheel 204 to rotate, and the driving wheel 204 drives the driven wheel 202 to rotate through the transmission belt 203, thereby driving the transmission rod 201 to rotate, and then driving the grinding cylinder 401 and the stirring assembly 5 to rotate. During the rotation of the grinding cylinder 401, the output end of the control lifting rod 407 is extended and retracted in a short range and quickly, driving the grinding cylinder 401 to rise and fall repeatedly in the soybean liquid. When the grinding cylinder 401 descends, the liquid itself will produce upward resistance, causing the grinding filter 402 to move vertically upward along the side wall of the annular groove until the top surface of the grinding filter 402 fits the top of the annular groove, and space appears under the grinding filter 402. At the same time, the resistance of the liquid will cause the sealing plate 404 to rotate upward to open the through hole 403. Subsequently, at the moment when the grinding cylinder 401 rises, the water flow under the grinding cylinder 401 will follow the grinding cylinder 401 due to inertia, thereby driving the soybean particles at the bottom from the through hole 403. The liquid enters the space below the grinding filter 402. As it rises, the liquid itself generates downward resistance, forcing the sealing plate 404 to rotate downward, closing the through hole 403, and the grinding filter 402 drops synchronously. The resistance of the liquid and the buffer spring 703 work together to quickly reset the grinding filter 402 and squeeze and crush the soybean particles below the grinding filter 402. After squeezing and crushing, the soybean fine material drops for the second time in the grinding cylinder 401. When the grinding filter 402 rises, it passes through the grinding filter 402 with the resistance of the water flow and is mixed into the liquid. The soybean coarse material remains below the grinding filter 402 and waits for the next squeezing, crushing and grinding, thereby completing the grinding and crushing of the soybean particles.

[0040] Then, stirring, during the rotation of the grinding cylinder 401, the stirring assembly 5 will be driven to stir the soybean slurry, and during the reciprocating lifting of the grinding cylinder 401, the resistance of the liquid will make the stirring rod 501 keep reciprocating swinging with the hinge point with the fixed frame 508 as the center of the circle while rotating with the grinding cylinder 401, so as to break up the soybeans accumulated under the feeding pipe 3. At the same time, the electromagnet 502 is controlled to be energized to generate attraction to the permanent magnet 505, thereby attracting the telescopic rod 504 to approach the stirring rod 501, until the end of the telescopic rod 504 and the end of the stirring rod 501 are in contact, so that the arc plate 507 is away from the inner wall of the mixing barrel 101, forming a state of a stirring blade with a fixed length, and fully stirring the soybean slurry.

[0041] Then, the material is discharged, and the output end of the hydraulic cylinder 801 is controlled to retract, driving the blocking block 802 to descend along the discharge cavity until the top surface of the blocking block 802 is flush with the lowest point of the discharge port 9, and the soybean slurry is discharged.

[0042] Finally, clean up, control the output end of the lifting rod 407 to retract, drive the grinding cylinder 401 to separate from the soybean slurry and rise to above the soybean slurry liquid level in the mixing barrel 101, control the limit plate 405 to retract, and the sealing plate 404 to rotate downward, open the through hole 403, and the soybean slurry remaining in the grinding cylinder 401 is discharged from the through hole 403. Then control the output end of the lifting rod 407 to slowly extend, drive the grinding cylinder 401 and the stirring assembly 5 to slowly descend, and at the same time, control the electromagnet 502 to cut off the power, lose the attraction to the permanent magnet 505, and the telescopic spring 503 drives the telescopic rod 504 away from the stirring rod 501 and resets instantly. Since the grinding cylinder 401 is still in the process of continuous rotation, it will cause the telescopic rod 504 to generate centrifugal force. Under the support of the centrifugal force, the telescopic rod 504 will continue to move away from the stirring rod 501 after a short reset. At this time, the telescopic spring 503 is in a stretched state. When it is detected that the stretching amount of the telescopic spring 503 remains stable and no longer increases, it can be determined that the current arc plate 507 is already close to the inner wall of the mixing barrel 101. At this time, the power assembly 2 is controlled to drive the grinding cylinder 401 to accelerate the rotation speed. The centrifugal force will cause the soybean slurry remaining on the grinding cylinder 401 to be thrown onto the inner wall of the mixing barrel 101, and then the arc plate 507 rotates and scrapes it off, thereby completing the cleaning of the part above the static liquid surface on the inner wall of the mixing barrel 101, preventing the soybean slurry from solidifying on the upper half of the inner wall of the mixing barrel 101.

[0043] Embodiment 2: Based on the technical solution of the above-mentioned embodiment 1, after the stirring component 5 rotates and stirs with the grinding cylinder 401 for a certain period of time, the liquid will form a stable vortex, the soybean particles will remain relatively still and rotate synchronously with the water flow. Although the stirring rod 501 and the telescopic rod 504 will swing with the rise and fall of the grinding cylinder 401 to break up the soybean particles longitudinally, the soybean particles are not broken up in the horizontal direction and cannot be fully broken up. In addition, when the soybean slurry is ground into a uniform slurry, the device cannot judge the uniformity of the slurry, and cannot stop grinding and discharge the soybean slurry in time, which is not conducive to improving production efficiency. Therefore, the following technical solutions are proposed to solve the above-mentioned technical problems.

[0044] By controlling the power supply of the electromagnet 502 to control the reciprocating extension and retraction of the telescopic rod 504, the soybean particles can be horizontally broken up. Figure 5 As shown, when the grinding cylinder 401 does not start to rotate, the stirring assembly 5 does not rotate and no centrifugal force is generated. In this state, the telescopic spring 503 is in a relaxed state and has no compression, which is recorded as the initial compression.

[0045] As the stirring assembly 5 rotates with the grinding cylinder 401, due to the generation of centrifugal force, the telescopic rod 504 will move away from the stirring rod 501, thereby causing the telescopic spring 503 to stretch. The stretching amount of the telescopic spring 503 gradually increases until the arc plate 507 is close to the inner wall of the mixing barrel 101, and the stretching amount no longer changes. The stretching amount is recorded as the maximum stretching amount.

[0046] The control electromagnet 502 is supplied with current and gradually increases, generating attraction to the permanent magnet 505, thereby attracting the telescopic rod 504 to approach the stirring rod 501. The current compression of the telescopic spring 503 can be detected in real time to determine the distance between the telescopic rod 504 and the stirring rod 501. When the compression of the telescopic spring 503 gradually increases and remains stable, it means that the end of the telescopic rod 504 and the end of the stirring rod 501 are in contact with each other, and the arc plate 507 is located away from the inner wall of the mixing barrel 101. At this time, the control electromagnet 502 is supplied with current. The current no longer increases, and the current is controlled to gradually decrease. When the compression of the telescopic spring 503 gradually decreases to no compression and then generates a stretching amount, and the stretching amount increases to the maximum stretching amount, it means that the current arc plate 507 is already close to the inner wall of the mixing barrel 101. At this time, the current passed through the electromagnet 502 is controlled to gradually increase, attracting the telescopic rod 504 to approach the stirring rod 501, thereby driving the arc plate 507 to achieve longitudinal swing, thereby ensuring that the arc plate 507 can swing horizontally while swinging longitudinally, thereby fully breaking up the soybean particles.

[0047] By adjusting the current passed through the electromagnet 502, the attraction force on the permanent magnet 505 is adjusted. The attraction force cooperates with the centrifugal force generated by the rotation of the grinding cylinder 401, so that the telescopic rod 504 drives the arc plate 507 to move back and forth in the horizontal direction, and cooperates with the lifting of the grinding cylinder 401 to drive the arc plate 507 to swing in the vertical direction, so as to fully break up the soybean particles rotating at the same speed as the liquid, thereby ensuring the uniformity of grinding and mixing of the soybean slurry.

[0048] When the soybean slurry is ground and stirred into a uniform paste, it can be discharged. In this embodiment, the uniformity of the soybean slurry is determined by the reset component 6 in cooperation with the stirring component 5. Figure 2 as well as Figure 5 As shown, during the lifting and lowering of the grinding cylinder 401, due to the resistance of the liquid, the stirring rod 501 will swing up and down. During the up and down swinging of the stirring rod 501, the telescopic support rod 602 will slide repeatedly along the inner wall of the reset rod 601. The upper and lower telescopic support rods 602 slide in opposite directions, so that the upper and lower reset springs 603 produce the same deformation amount but in opposite directions, that is, the upper and lower reset springs 603 produce compression and tension respectively.

[0049] First, control the grinding cylinder 401 to grind and stir the evenly ground soybean slurry at the lifting height, frequency and speed required by production. At this time, the deformation of the reset spring 603 in the upper reset component 6 remains consistent, and the deformation of the reset spring 603 in the lower reset component 6 is consistent with the deformation at the top, but the deformation direction is always opposite. Record the deformation of the reset spring 603 at this time and set it as a comparison value.

[0050] When grinding and stirring are carried out in actual production, the grinding cylinder 401 is controlled to grind and stir at the same lifting height, frequency and speed as in the comparison value state, and the deformation amount of the comparison value is used as a reference to detect the deformation amount of the reset spring 603 in real time. When the deformation amount of the reset spring 603 is basically consistent with the comparison value, it can be judged that the uniformity of the soybean slurry grinding at this time is qualified and can be discharged. Then the output end of the hydraulic cylinder 801 is controlled to retract, driving the blocking block 802 to descend along the discharge chamber to open the discharge port 9 and discharge the soybean slurry.

[0051] By real-time detecting the deformation amount caused by the compression or extension of the return spring 603 by pressing the telescopic support rod 602 by the stirring rod 501, the uniformity of the current soybean slurry grinding and stirring is judged, thereby ensuring that the soybean slurry can be stopped and discharged in time after the grinding is qualified, ensuring the rapid progress of the subsequent soybean processes and ensuring production efficiency.
