Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grain grinding, in particular to a grinding device for processing bean product raw materials. BACKGROUND

[0002] The raw materials of bean products mainly include soybeans, mung beans, black beans, peas and broad beans, etc. These beans contain rich protein and other nutrients, and various bean products can be made through different processing methods.

[0003] In the processing of bean product raw materials, the grinding device is one of the important equipment, which directly affects the product quality and production efficiency. The colloid mill is a commonly used grinding equipment. The motor drives the gear and the matching gear to rotate at high speed. One rotates at high speed and the other is static. The processed material generates downward spiral impact force through its own weight or external pressure. When passing through the gap between the fixed and rotating gears, it is subjected to strong shearing force, friction force and high-frequency vibration, etc. Therefore, it is effectively emulsified, dispersed, homogenized and pulverized, achieving the effect of superfine grinding and emulsification.

[0004] For example, the patent document with publication number CN222152362U discloses a colloid mill. The colloid mill includes a transmission base, a colloid mill body mounted on the transmission base, and a motor. The colloid mill body is provided with a rotor and a stator. One side of the colloid mill body is provided with a discharge port. The discharge port is provided with a discharge pipe. The discharge pipe is connected to a circulating cylinder. The circulating cylinder is connected to a circulating pipe. The motor drives the colloid mill body to rotate, grinding the material. The ground material passes through the discharge pipe, the circulating cylinder and the circulating pipe in sequence to enter the feed hopper for circulating grinding.

[0005] When the above grinding device grinds the raw materials, the raw materials are in disordered motion during the grinding process, which may be unevenly distributed on both sides of the grinding disc, causing local accumulation of the raw materials. The temperature in this area rises. Long-time grinding also increases the temperature inside the equipment. Excessive temperature can destroy some nutrients in the bean product raw materials, such as some heat-sensitive vitamins, thereby reducing the nutritional value of the bean product raw materials. SUMMARY

[0006] Therefore, the present application provides a grinding device for processing bean product raw materials, which solves the technical problem of reducing the nutritional value of bean product raw materials due to temperature rise during grinding in the prior art.

[0007] To solve the above technical problems, the present application provides a grinding device for processing bean product raw materials, which includes a shell and a grinding disc arranged in the shell. The grinding disc is driven by a driving motor. A uniform distribution disc is connected above the grinding disc. Uniform distribution plates are arranged on the uniform distribution disc.

[0008] The lower part of the grinding disc is rotationally and sealingly connected with a liquid storage cavity, the grinding disc is provided with a liquid inlet channel and a liquid outlet channel, the upper part of the grinding disc is provided with an annular groove, the annular groove is rotationally and slidingly connected with a sealing plate, a liquid outlet cavity is left between the grinding disc, the sealing plate and the uniform distribution disc, the liquid storage cavity is communicated with the annular groove through the liquid inlet channel, and the liquid outlet cavity is communicated with the liquid storage cavity through the liquid outlet channel;

[0009] The grinding disc is installed on the rotating shaft, the rotating shaft is sleeved with a shaft sleeve, the sealing plate is installed on the shaft sleeve, a one-way valve is installed on the sealing plate, the uniform distribution disc and the shaft sleeve are both connected with sawtooth-shaped inclined blocks which are in sliding cooperation with each other, and the rotating of the uniform distribution disc drives the shaft sleeve and the sealing plate to lift or drop, so as to control the opening and closing of the one-way valve.

[0010] By adopting the above technical scheme, the driving motor drives the rotating shaft and the grinding disc to rotate, the grinding disc drives the uniform distribution disc to rotate, and the uniform distribution plate on the uniform distribution disc has a guiding and distributing effect on the falling raw materials when the uniform distribution plate rotates synchronously with the uniform distribution disc, which is conducive to uniformly dispersing the raw materials to the grinding surface of the grinding disc and reducing the local accumulation of the raw materials on the grinding disc, thereby being conducive to improving the grinding effect and reducing the local temperature rise caused by the local accumulation.

[0011] During the rotation of the uniform distribution disc, the shaft sleeve is driven to lift or drop through the cooperation of the sawtooth-shaped inclined blocks, and then the sealing plate is driven to lift or drop. When the sealing plate drops, the hydraulic pressure in the annular groove rises, which pushes the valve core of the one-way valve to overcome the resistance of the spring, so that the valve core is opened, and the cooling liquid in the annular groove enters the liquid outlet cavity through the one-way valve. When the sealing plate rises, the one-way valve is closed, the cooling liquid in the liquid outlet cavity enters the liquid storage cavity through the liquid outlet channel, the hydraulic pressure in the liquid storage cavity rises, and the cooling liquid in the liquid storage cavity enters the annular groove through the liquid inlet channel, thereby realizing the circulation of the cooling liquid. The circulation of the cooling liquid can take away heat and cool the raw materials in the grinding disc and the shell, which is conducive to reducing the phenomenon that the nutrients of the raw materials are lost or deteriorated due to the excessively high temperature in the shell.

[0012] Preferably, a plurality of crushing rings are slidingly arranged above the sleeve on the rotating shaft, a plurality of crushing knives are arranged at intervals on the crushing rings, and a return spring one is connected between the upper and lower crushing rings.

[0013] By adopting the above technical scheme, the plurality of crushing rings are distributed above and below the axis of the rotating shaft to form a multi-stage crushing structure. When the raw materials enter the grinding device, they will pass through different positions of the crushing rings in sequence, and the crushing knives on each crushing ring can preliminarily crush the raw materials. After multi-stage crushing, the particle size of the raw materials can be more effectively reduced to provide raw materials with a more suitable particle size for subsequent grinding processes, which is conducive to improving the overall processing efficiency and product quality and reducing the temperature rise during grinding.

[0014] The upper and lower crushing rings are connected by a return spring, which allows the gap between the crushing rings to be automatically adjusted according to the flow rate and particle size of the raw material, thus improving the crushing effect.

[0015] Preferably, a screen plate is connected to the bushing, and the screen plate is located below the crushing ring.

[0016] By adopting the above technical solution, after the crushing ring crushes the large particles of raw material, the raw material falls onto the screen plate. The screen plate can screen out the fine particles that meet the particle size requirements, allowing them to pass through the screen holes and enter the subsequent grinding area, which is beneficial to improving the grinding quality. Large particles that do not meet the particle size standard are intercepted on the screen plate, and the crushing blades continue to crush them.

[0017] The screen plate can move up and down with the bushing, which helps to reduce the clogging of the screen holes by the raw materials.

[0018] Preferably, a guide plate is connected to the shaft above the crushing ring. The upper and lower ends of the guide plate are both conical. A feeding cylinder is installed inside the housing. An annular feeding plate is inclinedly provided on the inner wall of the feeding cylinder. Feeding gaps are left between the guide plate and the feeding cylinder, and between the lower end of the guide plate and the feeding plate.

[0019] By adopting the above technical solution, the raw material falls from above the guide plate and along the feeding gap between the guide plate and the feeding cylinder. The upper end face of the guide plate is designed in a conical shape, which helps to disperse the raw material and reduce local accumulation. During the crushing process, the raw material splashes. The lower end face of the guide plate is also designed in a conical shape. When the splashed raw material collides with the lower end face of the guide plate, it spreads to the edge through rebound and gravity, and then falls from the feeding gap, which helps to increase the dispersion of the raw material.

[0020] Preferably, the outer side of the housing is connected to a lifting outer cylinder by a thread, and the inner side of the housing is slidably connected to a lifting inner cylinder. The lifting inner cylinder and the lifting outer cylinder are rotatably connected. A grinding gap is left between the lifting inner cylinder and the grinding disc. The outer diameter of the grinding disc increases from top to bottom.

[0021] By adopting the above technical solution, the outer lifting cylinder on the outside of the shell is connected by a thread. When the outer cylinder is rotated, it can drive the inner lifting cylinder on the inside to slide up and down, thereby changing the grinding gap between the inner lifting cylinder and the grinding disc. A smaller grinding gap is suitable for producing finer bean product raw material powder, while a larger gap can be used for preliminary grinding or processing products with less stringent particle size requirements, meeting diverse production needs.

[0022] The outer diameter of the grinding disc increases from top to bottom, causing the grinding gap to decrease from top to bottom. When the raw material enters the grinding gap from above, it will gradually move downwards and be squeezed and ground by different outer diameter parts as the grinding disc rotates. The raw material is first initially ground and then refined, which helps to improve grinding efficiency.

[0023] Preferably, the feeding cylinder is slidably connected inside the lifting inner cylinder, and a return spring is connected between the feeding cylinder and the lifting inner cylinder. The feeding cylinder can abut against the uniform distribution plate. Multiple abutment plates are provided at intervals along the edge of the screen plate. Multiple sliding grooves are provided on the inner wall of the feeding cylinder to restrict the rotation of the abutment plates. The abutment plates can slide up and down in the sliding grooves and abut against the upper and lower edges of the sliding grooves.

[0024] By adopting the above technical solution, the chute guides the up-and-down movement of the abutment plate and restricts its rotation, thereby restricting the rotation of the screen plate and the bushing, allowing the bushing to move up and down. When the screen plate moves upward with the bushing, the abutment plate can slide within the chute and abut against the upper edge of the chute, thus driving the chute and the discharge cylinder upward, compressing the second return spring. When the screen plate moves downward with the bushing, the discharge cylinder loses the upward lifting force of the screen plate. Under the action of the discharge cylinder's own weight and the elastic force of the second return spring, the discharge cylinder falls stably, thus helping the screen plate fall stably under its own weight and the guiding constraint of the chute.

[0025] Preferably, a pressure cap is installed above the lifting inner cylinder, and the pressure cap and the lifting outer cylinder are rotatably connected. A lifting gap is left between the pressure cap, the lifting inner cylinder, the lifting outer cylinder and the shell. A boss is provided at the end of the lifting inner cylinder, and a guide post is installed at the upper end of the shell within the lifting gap. The guide post is slidably connected to the boss.

[0026] By adopting the above technical solution, the outer cylinder is rotated to raise and lower the outer cylinder. The outer cylinder then drives the pressure cap and the inner cylinder to rise and fall in sequence. The guide column can restrict the radial movement of the inner cylinder, allowing the inner cylinder to move along its own axis, thereby adjusting the grinding gap.

[0027] Preferably, a base is installed below the shell, a liquid storage chamber is set inside the base, an inlet pipe is connected to one side of the liquid storage chamber and a outlet pipe is connected to the other side of the liquid storage chamber.

[0028] By adopting the above technical solution, the base provides support for the shell, and the coolant is delivered into the storage chamber through the inlet pipe and the heated coolant in the storage chamber is output through the outlet pipe, so as to realize the replacement of coolant and facilitate the stable cooling of raw materials and grinding disc by coolant.

[0029] Preferably, a feed hopper is installed at the upper end of the housing, and a spiral blade is installed on the rotating shaft above the guide plate, with the spiral blade extending into the feed hopper.

[0030] By adopting the above technical solution, the raw materials are conveyed into the shell through the feed hopper. Under the pushing action of the spiral blades, the raw materials fall evenly onto the guide plate and along the feeding gap, which helps to reduce the phenomenon of local concentration of raw materials.

[0031] Preferably, a discharge pipe is provided on one side of the shell, and a circulation pipe is connected to the discharge pipe, which extends into the feed hopper.

[0032] By adopting the above technical solution, the raw materials discharged from the discharge pipe may contain some incompletely processed particles. These particles can be sent back to the feed hopper through the circulation pipe and re-enter the processing flow until the preset fineness is achieved.

[0033] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0034] 1. The present invention distributes the raw materials evenly by means of a uniform distribution disc, which helps to reduce the phenomenon of local temperature rise caused by local accumulation of raw materials. At the same time, the circulation of coolant can remove heat and cool down the raw materials in the grinding disc and shell, which helps to reduce the impact of excessively high temperature in the shell on the nutritional value of the raw materials.

[0035] 2. When the raw material enters the grinding device, it will pass through the crushing rings at different positions in sequence. The crushing blades on each crushing ring can perform preliminary crushing of the raw material. The screen screens the crushed raw material to provide raw material with a more suitable particle size for the subsequent grinding process. This is beneficial to improving the overall processing efficiency and product quality, and also helps to reduce the phenomenon of temperature rise during grinding.

[0036] 3. The upper end face of the guide plate is designed as a cone, which helps to disperse the raw materials and reduce local accumulation of raw materials. The lower end face of the guide plate is also designed as a cone. During the collision with the lower end face of the guide plate, the splashed raw materials are diffused to the edge through rebound and gravity, and then fall from the feeding gap, which helps to increase the dispersion of raw materials.

[0037] 4. The grinding gap between the lifting inner cylinder and the grinding disc is adjustable, which can meet diverse production needs. The grinding gap decreases from top to bottom, and the raw materials are first pre-ground and then refined, which helps to improve grinding efficiency. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the embodiments of the present invention. Figures 1-7 The technical solutions of the embodiments of the present invention will be clearly and completely described.

[0047] Example

[0048] This embodiment provides a grinding device for processing raw materials of soybean products, such as... Figure 2 and Figure 4 As shown, it includes a housing 1 and a grinding disc 2.

[0049] like Figure 1 and Figure 2 As shown, the housing 1 is mounted on the base 3, which provides support for the housing 1. A drive shaft 31 is rotatably connected to the base 3, and the drive shaft 31 is located inside the housing 1. The grinding disc 2 is mounted on the drive shaft 31.

[0050] like Figure 1 and Figure 2 As shown, a drive motor 4 for driving the drive shaft 31 to rotate is provided on the base 3, and the output shaft of the drive motor 4 is connected to the drive shaft 31 by a transmission belt.

[0051] like Figure 1 and Figure 2 As shown, a feed inlet is provided on the top of the housing 1, and a feed hopper 11 is installed on the feed inlet. A rotating shaft 5 is rotatably installed inside the feed hopper 11, and a spiral blade 51 is installed above the rotating shaft 5. The spiral blade 51 extends into the feed hopper 11.

[0052] like Figure 2 and Figure 3 As shown, a lifting outer cylinder 6 is threadedly connected to the outer side of the housing 1, and a lifting inner cylinder 7 is slidably connected to the inner wall of the housing 1. The axes of the lifting outer cylinder 6, the housing 1, the lifting inner cylinder 7, and the drive shaft 31 are collinear. A pressure cap 71 is installed at the upper end of the lifting inner cylinder 7, and the pressure cap 71 is rotatably connected to the lifting outer cylinder 6.

[0053] like Figure 2 and Figure 3 As shown, a lifting gap is left between the pressure cap 71, the lifting inner cylinder 7, the lifting outer cylinder 6 and the housing 1. The end of the lifting inner cylinder 7 is provided with a boss 72. A guide post 12 is installed at the upper end of the housing 1 in the lifting gap. The guide post 12 and the boss 72 are slidably connected up and down.

[0054] like Figure 2 and Figure 4 As shown, the grinding disc 2 is installed below the rotating shaft 5 and above the drive shaft 31. The axes of the rotating shaft 5 and the drive shaft 31 are collinear. The grinding disc 2 is located inside the lifting inner cylinder 7. A grinding gap is left between the grinding disc 2 and the lifting inner cylinder 7. The outer diameter of the grinding disc 2 increases from top to bottom so that the grinding gap decreases from top to bottom.

[0055] like Figure 2 and Figure 3 As shown, a handle 61 is installed on the outside of the lifting outer cylinder 6. Moving the handle 61 causes the lifting outer cylinder 6 to rotate and move up and down. The lifting outer cylinder 6 drives the pressure cover 71 and the lifting inner cylinder 7 to move up and down in sequence. The guide column 12 can restrict the radial movement of the lifting inner cylinder 7, so that the lifting inner cylinder 7 moves along its own axis, that is, the lifting inner cylinder 7 moves up and down, thereby realizing the adjustment of the grinding gap.

[0056] like Figure 2 and Figure 4 As shown, a smaller grinding gap is suitable for producing finer bean product raw material powder, while a larger gap can be used for preliminary grinding or processing products with less stringent particle size requirements, meeting diverse production needs. The outer diameter of the grinding disc 2 increases from top to bottom, causing the grinding gap to decrease from top to bottom. As the grinding disc 2 rotates, the raw material gradually moves downward and is squeezed and ground by different outer diameter sections. The raw material undergoes preliminary grinding before being refined, which helps to improve grinding efficiency.

[0057] like Figure 2 andFigure 3 As shown, a feeding cylinder 73 is slidably connected to the inner lifting cylinder 7. The axis of the feeding cylinder 73 coincides with the axis of the inner lifting cylinder 7, and the feeding cylinder 73 is located below the feeding hopper 11. Both the feeding cylinder 73 and the inner lifting cylinder 7 are provided with mutually sliding grooves to achieve relative sliding between them.

[0058] like Figure 2 and Figure 3 As shown, a guide plate 52 is provided on the rotating shaft 5 below the stirring blades. Both the upper and lower ends of the guide plate 52 are conical. That is, the diameter of the upper end of the guide plate 52 increases from top to bottom, and the diameter of the lower end of the guide plate 52 decreases from top to bottom.

[0059] like Figure 2 and Figure 3 As shown, the guide plate 52 is located inside the feeding cylinder 73. An annular feeding plate 731 is inclined on the inner wall of the feeding cylinder 73, and the feeding plate 731 is inclined from top to bottom towards the axis of the feeding cylinder 73. Feeding gaps are left between the guide plate 52 and the feeding cylinder 73, and between the lower end face of the guide plate 52 and the feeding plate 731.

[0060] like Figure 2 and Figure 3 As shown, the raw material is fed into the housing 1 through the feed hopper 11. Under the pushing action of the spiral blades 51, the raw material falls evenly onto the guide plate 52 and along the feeding gap, which helps to reduce the phenomenon of local concentration of raw material, thereby improving the grinding effect and reducing the phenomenon of local temperature rise caused by local accumulation. The upper end face of the guide plate 52 is designed as a cone shape, which helps to disperse the raw material and reduce local accumulation of raw material.

[0061] like Figure 2 and Figure 4 As shown, multiple crushing rings 53 are slidably connected to the rotating shaft 5 below the guide plate 52. Multiple crushing blades 531 are spaced apart on each crushing ring 53. Return springs 532, which are cylindrical springs, are connected between the upper and lower crushing rings 53 and between the crushing rings 53 and the guide plate 52, and are sleeved on the rotating shaft 5. A crushing chamber is formed between the crushing rings 53 and the inner wall of the feed cylinder 73.

[0062] like Figure 2 and Figure 4 As shown, multiple crushing rings 53 are distributed vertically along the axis of the rotating shaft 5, forming a multi-stage crushing structure. After the raw material is crushed by the crushing rings 53, its size is reduced, which is beneficial to improving the quality of subsequent grinding and also helps to reduce the temperature rise during grinding.

[0063] like Figure 2 and Figure 4As shown, to improve the crushing effect, the blade of the crusher 531 is provided with a raised ridge. The upper and lower crushing rings 53 are connected by a return spring 532, so that the gap between the crushing rings 53 can be automatically adjusted according to the flow rate and particle size of the raw material, which also helps to improve the crushing effect.

[0064] like Figure 2 and Figure 4 As shown, a bushing 54 is fitted on the rotating shaft 5 below the crushing ring 53, allowing relative sliding and rotation between the bushing 54 and the rotating shaft 5. A screen plate 55 is connected to the upper end of the bushing 54, and the surface of the screen plate 55 can abut against the crushing blade 531.

[0065] like Figure 2 and Figure 4 As shown, the raw material crushed by the crusher blade 531 falls onto the screen plate 55. The screen plate 55 can screen out fine particles that meet the particle size requirements, allowing them to pass through the screen holes and enter the subsequent grinding area, which is beneficial to improving the grinding quality. Large particles that do not meet the particle size standard are intercepted on the screen plate 55, and the crusher blade 531 continues to crush them.

[0066] like Figure 2 and Figure 3 As shown, during the crushing process of the crusher blade 531, the raw material will splash. The lower end face of the guide plate 52 is also designed as a conical surface. During the collision with the lower end face of the guide plate 52, the splashed raw material will spread to the edge through rebound and gravity, and then fall into the crushing chamber from the feeding gap. This helps to increase the dispersion of the raw material and reduce the phenomenon of excessive temperature caused by local accumulation of raw material.

[0067] like Figure 4 and Figure 5 As shown, a uniform distribution disk 56 is fitted onto the bushing 54. The uniform distribution disk 56 is located below the sieve plate 55 and above the grinding disc 2. The uniform distribution disk 56 is connected to the grinding disc 2, and multiple arc-shaped uniform distribution plates 561 are spaced apart on the uniform distribution disk 56. Gaps are left between the uniform distribution disk 56 and the feed cylinder 73 and the lifting inner cylinder 7 to allow the raw material to fall.

[0068] like Figure 4 and Figure 5 As shown, the raw material falling from the sieve plate 55 lands on the uniform distribution disk 56. The grinding disk 2 drives the uniform distribution disk 56 to rotate. When the arc-shaped uniform distribution plate 561 on the uniform distribution disk 56 rotates synchronously with the uniform distribution disk 56, it guides and diverts the falling raw material, which helps to evenly distribute the raw material to the grinding surface of the grinding disk 2 and reduces the phenomenon of local accumulation of raw material on the grinding disk 2. While improving the grinding effect, it also helps to reduce the phenomenon of local temperature rise caused by local accumulation.

[0069] like Figure 4 , Figure 6 andFigure 7 As shown, the outer wall of the bushing 54 and the middle part of the distribution disk 56 are provided with mutually slidingly fitted sawtooth-shaped inclined blocks 57. As the distribution disk 56 rotates, the bushing 54 can be driven to rise and fall under the sliding cooperation of the inclined surfaces of the two inclined blocks 57. The bushing 54 drives the screen plate 55 to rise and fall, which helps to reduce the clogging of the screen holes on the screen plate 55.

[0070] like Figure 3 and Figure 4 As shown, a return spring 74 connects the feeding cylinder 73 and the lifting inner cylinder 7. The edge of the evenly distributed plate 561 on the evenly distributed disk 56 can abut against the feeding cylinder 73. Multiple sliding grooves 732 are opened in the vertical direction on the inner wall of the feeding cylinder 73. Multiple abutment plates 551 are spaced apart on the edge of the screen plate 55. The number of abutment plates 551 is the same as the number of sliding grooves 732. The abutment plates 551 can slide up and down in the sliding grooves 732 and abut against the upper and lower edges of the sliding grooves 732.

[0071] like Figure 3 , Figure 4 and Figure 6 As shown, the chute 732 guides the up-and-down movement of the abutment plate 551 and limits the rotation of the screen plate 55 and the bushing 54, allowing the bushing 54 to rise and fall under the sliding engagement of the two inclined blocks 57. When the screen plate 55 moves upward with the bushing 54, the abutment plate 551 can slide within the chute 732 and abut against the upper edge of the chute 732, thereby driving the chute 732 and the feed cylinder 73 to move upward, compressing the second return spring 74.

[0072] like Figure 3 and Figure 4 As shown, when the screen plate 55 moves down with the bushing 54, the feed cylinder 73 loses the upward lifting force of the screen plate 55. Under the action of the feed cylinder 73's own weight and the elastic force of the return spring 74, the feed cylinder 73 falls stably, which in turn helps the screen plate 55 fall stably under its own weight and the guiding constraint of the slide groove 732.

[0073] like Figure 2 and Figure 4 As shown, an annular groove 21 is provided at the upper end of the grinding disc 2, and a step 211 is provided on the groove wall of the annular groove 21. A step 562 is provided on the lower end face of the uniform distribution disc 56 so that the edge of the uniform distribution disc 56 and the edge of the grinding disc 2 are connected, and a cavity is left between the uniform distribution disc 56 and the grinding disc 2.

[0074] like Figure 2 and Figure 4 As shown, a sealing plate 22 is rotatably and slidably connected in the annular groove 21. A liquid outlet cavity is left between the grinding disc 2, the sealing plate 22 and the uniform distribution disc 56. Multiple one-way valves 221 are installed on the sealing plate 22.

[0075] like Figure 2 andFigure 4 As shown, the grinding disc 2 is provided with multiple liquid inlet channels 23 and liquid outlet channels 24. The liquid inlet channels 23 are located at the bottom of the annular groove 21, and the liquid outlet channels 24 are located on the step 211 of the grinding disc 2. The axes of the liquid inlet channels 23 and the liquid outlet channels 24 are parallel to the axis of the drive shaft 31.

[0076] like Figure 2 and Figure 4 As shown, a liquid storage chamber 8 is rotatably and sealed below the grinding disc 2, and the liquid storage chamber 8 is rotatably connected to the drive shaft 31. A liquid inlet pipe 25 is provided below the liquid inlet channel 23, and the lower end of the liquid inlet pipe 25 extends into the bottom of the liquid storage chamber 8. The liquid storage chamber 8 is connected to the annular groove 21 through the liquid inlet channel 23, and the liquid outlet chamber is connected to the liquid storage chamber 8 through the liquid outlet channel 24.

[0077] like Figure 2 and Figure 4 As shown, the bushing 54 drives the sealing plate 22 to rise and fall, thereby controlling the opening and closing of the one-way valve 221. Specifically, when the sealing plate 22 descends, the hydraulic pressure in the annular groove 21 increases, which pushes the valve core of the one-way valve 221 to overcome the resistance of the spring, causing the valve core to open. The coolant in the annular groove 21 then enters the outlet chamber through the one-way valve 221. When the sealing plate 22 rises, the one-way valve 221 closes, and the coolant in the outlet chamber enters the storage chamber 8 through the outlet channel 24. The hydraulic pressure in the storage chamber 8 increases, causing the coolant in the storage chamber 8 to sequentially enter the annular groove 21 through the inlet pipe 25 and the inlet channel 23, thus achieving coolant circulation.

[0078] like Figure 2 and Figure 4 As shown, the liquid storage chamber 8 is set inside the base 3. One side of the liquid storage chamber 8 is connected to an inlet pipe 81 that penetrates the base 3, and the other side of the liquid storage chamber 8 is connected to an outlet pipe 82 that penetrates the base 3.

[0079] like Figure 1 and ​ As shown, coolant is supplied to the storage chamber 8 through the inlet pipe 81 and the heated coolant in the storage chamber 8 is discharged through the outlet pipe 82, thereby replacing the coolant. The circulation of the coolant can remove heat and cool down the raw materials in the grinding disc 2 and the shell 1, which helps to reduce the loss of nutrients or deterioration of the raw materials due to excessively high temperature in the shell 1.

[0080] like ​ As shown, a discharge pipe 13 is provided on one side of the housing 1. A three-way valve 14 is installed on the discharge pipe 13. The three-way valve 14 is connected to a circulation pipe 15, which extends into the feed hopper 11. The raw material discharged from the discharge pipe 13 may contain some incompletely processed particles. This part of the raw material is sent back to the feed hopper 11 through the circulation pipe 15 and can re-enter the processing flow until the preset fineness is achieved.

[0081] The implementation principle of a grinding device for processing raw materials of soybean products in this embodiment:

[0082] The drive motor 4 drives the drive shaft 31 and the rotating shaft 5 to rotate, conveying raw materials into the feed hopper 11. Under the conveying action of the spiral blade 51, the raw materials are evenly conveyed onto the guide plate 52. Under the guidance of the guide plate 52, the raw materials fall into the crushing chamber along the feeding gap. The crushing blade 531 crushes the raw materials, and the crushed raw materials fall onto the screen plate 55.

[0083] Raw materials that meet the particle size requirements enter the subsequent grinding area through the sieve holes, while large particles that do not meet the particle size standard are intercepted on the sieve plate 55 and crushed by the crusher blade 531. During the crushing process, the raw materials will splash. When the splashed raw materials collide with the lower end face of the guide plate 52, they will spread to the edge through rebound and gravity, which helps to increase the dispersion of the raw materials and reduce the phenomenon of excessive temperature caused by local accumulation of raw materials.

[0084] The drive shaft 31 drives the grinding disc 2 and the distribution disc 56 to rotate. The raw material falling from the sieve plate 55 lands on the distribution disc 56. When the arc-shaped distribution plate 561 on the distribution disc 56 rotates synchronously with the distribution disc 56, it guides and diverts the falling raw material, which helps to evenly distribute the raw material to the grinding surface of the grinding disc 2 and reduces the phenomenon of local accumulation of raw material on the grinding disc 2.

[0085] The grinding disc 2 grinds the raw material. After grinding, the raw material is discharged from the discharge pipe and sent back to the feed hopper 11 through the circulation pipe 15 for repeated grinding to achieve the preset fineness.

[0086] During the rotation of the uniform distribution disk 56, the uniform distribution disk 56 and the two inclined blocks 57 on the bushing 54 slide together, which drives the bushing 54 to rise and fall. The bushing 54 drives the screen plate 55 and the sealing plate 22 to rise and fall. The rising and falling of the screen plate 55 helps to reduce the clogging of the screen holes on the screen plate 55.

[0087] When the sealing plate 22 descends, the one-way valve 221 opens, and the coolant in the annular groove 21 enters the outlet chamber through the one-way valve 221. When the sealing plate 22 rises, the one-way valve 221 closes, and the coolant in the outlet chamber enters the storage chamber 8 through the outlet channel 24. The hydraulic pressure in the storage chamber 8 increases, and the coolant in the storage chamber 8 enters the annular groove 21 through the inlet pipe 25 and the inlet channel 23 in sequence, thereby realizing the circulation of the coolant. The circulation of the coolant can remove heat and cool down the raw materials in the grinding disc 2 and the shell 1, which helps to reduce the phenomenon of loss or deterioration of nutrients in the raw materials due to excessively high temperature in the shell 1.

[0088] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
