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 of the material.

[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 with a circulating cylinder. The circulating cylinder is connected with a circulating pipe. The motor drives the colloid mill body to rotate, and the material is ground. 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, and the internal temperature of the equipment also rises after long-time grinding. The high temperature can damage 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 at intervals. 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; 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 rotation 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.

[0008] 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 local accumulation.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] The gap between the upper and lower crushing rings is connected by a return spring, so that the gap between the crushing rings can be automatically adjusted according to the flow and particle size of the raw materials, thereby improving the crushing effect.

[0013] Preferably, a sieve plate is connected to the shaft sleeve and located below the crushing ring.

[0014] After the crushing ring crushes the large-particle raw materials, the raw materials fall onto the sieve plate. The sieve plate can screen out fine particles meeting the particle size requirement and make them pass through the sieve hole into the subsequent grinding area, thereby improving the grinding quality. The large particles that do not meet the particle size requirement are intercepted on the sieve plate, and the crushing knife continues to crush them.

[0015] The sieve plate can move up and down with the shaft sleeve, thereby reducing the clogging of the sieve hole by the raw materials.

[0016] Preferably, a guide plate is connected to the upper part of the rotating shaft above the crushing ring, the upper end face and the lower end face of the guide plate are both conical, a discharge cylinder is installed in the shell, an annular discharge plate is obliquely arranged on the inner wall of the discharge cylinder, and a discharge gap is left between the guide plate and the discharge cylinder and between the lower end face of the guide plate and the discharge plate.

[0017] Through the above technical scheme, the raw materials fall from above the guide plate and fall along the discharge gap between the guide plate and the discharge cylinder. The upper end face of the guide plate is designed to be conical, which is conducive to dispersing the raw materials and reducing the local accumulation of the raw materials. During the crushing process of the crushing knife, the raw materials may splash. The lower end face of the guide plate is also designed to be conical. The splashed raw materials spread to the edge through rebound and gravity action in the process of colliding with the lower end face of the guide plate, and then fall from the discharge gap, which is conducive to increasing the dispersion of the raw materials.

[0018] Preferably, a lifting outer cylinder is threadedly connected to the outside of the shell, a lifting inner cylinder is slidingly connected to the inside of the shell, the lifting inner cylinder is rotationally connected with the lifting outer cylinder, a grinding gap is left between the lifting inner cylinder and the grinding disc, and the outer diameter of the grinding disc gradually increases from top to bottom.

[0019] Through the above technical scheme, the lifting outer cylinder on the outside of the shell is threadedly connected. When the outer cylinder is rotated, the lifting inner cylinder on the inside can slide up and down, thereby changing the grinding gap between the lifting inner cylinder and the grinding disc. Smaller grinding gaps are suitable for producing bean product raw material powder with finer particle size, and larger gaps are suitable for preliminary grinding or processing products with low particle size requirement, thereby meeting the diversified production needs.

[0020] The outer diameter of the grinding disc gradually increases from top to bottom, so that the grinding gap gradually decreases from top to bottom. When the raw material enters the grinding gap from the top, the raw material will gradually move downward and be extruded and ground by different diameter parts with the rotation of the grinding disc. The raw material is first refined by preliminary grinding, which is beneficial to improve the grinding efficiency.

[0021] Preferably, the feeding cylinder is slidingly connected to the inside of the lifting inner cylinder, and a second return spring is connected between the feeding cylinder and the lifting inner cylinder. The feeding cylinder can abut against the uniform distribution disc. The edge of the sieve plate is provided with a plurality of abutting plates at intervals. A plurality of sliding grooves capable of limiting the rotation of the abutting plates are formed on the inner wall of the feeding cylinder. The abutting plates can slide up and down in the sliding grooves and abut against the upper edge and the lower edge of the sliding grooves.

[0022] By adopting the above technical scheme, the sliding grooves guide the upward and downward movement of the abutting plates and limit the rotation of the abutting plates, thereby limiting the rotation of the sieve plate and the shaft sleeve. The shaft sleeve moves in the upward and downward directions. When the sieve plate moves upward with the shaft sleeve, the abutting plates can slide in the sliding grooves and abut against the upper edge of the sliding grooves, thereby driving the sliding grooves and the feeding cylinder to move upward, and the second return spring is compressed. When the sieve plate moves downward with the shaft sleeve, the feeding cylinder loses the upward lifting force of the sieve plate. Under the action of the gravity of the feeding cylinder and the elastic force of the second return spring, the feeding cylinder stably falls, thereby facilitating the stable falling of the sieve plate under the guidance and constraint of the gravity and the sliding grooves.

[0023] Preferably, a gland is installed at the upper part of the lifting inner cylinder, and the gland is rotationally connected between the lifting outer cylinder. A lifting gap is left between the gland, the lifting inner cylinder, the lifting outer cylinder and the shell. The end of the lifting inner cylinder is provided with a boss, and a guide column is installed at the upper end of the shell in the lifting gap. The guide column is slidingly connected with the boss.

[0024] By adopting the above technical scheme, the lifting outer cylinder is rotated to lift the lifting outer cylinder, which in turn drives the gland and the lifting inner cylinder to lift. The guide column can limit the radial movement of the lifting inner cylinder, so that the lifting inner cylinder moves along its own axis direction, thereby adjusting the grinding gap.

[0025] Preferably, a base is installed at the lower part of the shell, and a liquid storage cavity is arranged in the base. A liquid inlet pipe penetrating through the base is connected to one side of the liquid storage cavity, and a liquid outlet pipe penetrating through the base is connected to the other side of the liquid storage cavity.

[0026] By adopting the above technical scheme, the base provides support for the shell. The cooling liquid is delivered into the liquid storage cavity through the liquid inlet pipe, and the liquid outlet pipe outputs the cooling liquid heated in the liquid storage cavity, thereby realizing the replacement of the cooling liquid and facilitating the stable cooling of the raw material and the grinding disc by the cooling liquid.

[0027] Preferably, a feeding hopper is installed at the upper end of the shell, and a spiral blade is installed above the guide plate on the rotating shaft and extends into the feeding hopper.

[0028] By adopting the technical scheme, the raw materials are conveyed into the shell through the feeding hopper, and under the pushing action of the spiral blade, the raw materials are evenly dropped onto the guide plate and then fall along the discharging gap, thereby reducing the local concentration of the raw materials.

[0029] Preferably, a discharging pipe is arranged on one side of the shell, and a circulating pipe is connected to the discharging pipe and extends into the feeding hopper.

[0030] By adopting the technical scheme, the raw materials discharged from the discharging pipe may have some particles that are not completely processed, and these particles are sent back to the feeding hopper through the circulating pipe, so that they can re-enter the processing flow until the desired fineness is achieved.

[0031] The beneficial effects of the above technical scheme of the present application are as follows: 1. The raw materials are evenly distributed by the uniform distribution disc, which helps to reduce the local temperature rise caused by local accumulation of the raw materials. At the same time, the circulation of the cooling liquid can remove heat and cool the raw materials in the shell and the grinding disc, which helps to reduce the impact of high temperature in the shell on the nutritional value of the raw materials.

[0032] 2. When the raw materials enter the grinding device, they will pass through different positions of the crushing ring one by one. The crushing knives on each crushing ring can preliminarily crush the raw materials, and the screen can screen the crushed raw materials to provide more suitable particle size of the raw materials for the subsequent grinding process, which helps to improve the overall processing efficiency and product quality, and also helps to reduce the temperature rise during grinding.

[0033] 3. The upper end surface of the guide plate is designed in a conical shape, which helps to disperse the raw materials and reduce local accumulation of the raw materials. The lower end surface of the guide plate is also designed in a conical shape. The splashing raw materials will spread to the edge through rebound and gravity action during the collision with the lower end surface of the guide plate, and then fall from the discharging gap, which helps to increase the dispersion of the raw materials.

[0034] 4. The grinding gap between the lifting inner cylinder and the grinding disc is adjustable, which can meet the diversified production needs. The grinding gap decreases from top to bottom, and the raw materials are first refined after preliminary grinding, which helps to improve the grinding efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the application more clear, the following will combine the embodiments of the application with the drawings of the embodiments of the application to make a brief description. Figures 1-7 The technical scheme of the embodiments of the application is described clearly and completely.

[0038] EMBODIMENT The embodiment provides a grinding device for bean product raw material processing, which comprises a shell 1 and a grinding disc 2. Figure 2 and Figure 4 The shell 1 is arranged on a base 3, and the base 3 provides support for the shell 1.

[0039] As shown in Figure 1 and Figure 2 The base 3 is rotationally connected with a driving shaft 31, the driving shaft 31 is located in the shell 1, and the grinding disc 2 is arranged on the driving shaft 31.

[0040] As shown in Figure 1 and Figure 2 The base 3 is provided with a driving motor 4 for driving the driving shaft 31 to rotate, and the output shaft of the driving motor 4 is in transmission connection with the driving shaft 31 through a transmission belt.

[0041] As shown in Figure 1 and Figure 2As shown, the upper part of the shell 1 is provided with a feeding port, and a feeding hopper 11 is installed on the feeding port. A rotating shaft 5 is rotatably installed in the feeding hopper 11. A spiral blade 51 is installed on the upper part of the rotating shaft 5 and extends into the feeding hopper 11.

[0042] As shown in Figure 2 and Figure 3 , the outer side of the shell 1 is threadedly connected with a lifting outer cylinder 6. The inner wall of the shell 1 is slidably connected with a lifting inner cylinder 7. The axis of the lifting outer cylinder 6, the shell 1, the lifting inner cylinder 7 and the driving shaft 31 are collinear. A gland 71 is installed on the upper end of the lifting inner cylinder 7, and the gland 71 is rotatably connected with the lifting outer cylinder 6.

[0043] As shown in Figure 2 and Figure 3 , a lifting gap is left between the gland 71, the lifting inner cylinder 7, the lifting outer cylinder 6 and the shell 1. The end of the lifting inner cylinder 7 is provided with a boss 72. A guide column 12 is installed on the upper end of the shell 1 in the lifting gap. The guide column 12 is slidably connected with the boss 72.

[0044] As shown in Figure 2 and Figure 4 , the grinding disc 2 is installed below the rotating shaft 5 and above the driving shaft 31. The axis of the rotating shaft 5 is collinear with the driving shaft 31. The grinding disc 2 is located in 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 on one side, so that the grinding gap decreases from top to bottom.

[0045] As shown in Figure 2 and Figure 3 , a handle 61 is installed on the outer side of the lifting outer cylinder 6. The handle 61 rotates and lifts the lifting outer cylinder 6. The lifting outer cylinder 6 drives the gland 71 and the lifting inner cylinder 7 to lift in turn. The guide column 12 can limit the radial movement of the lifting inner cylinder 7, so that the lifting inner cylinder 7 moves along its own axis, i.e. the lifting inner cylinder 7 lifts, thereby adjusting the grinding gap.

[0046] As shown in Figure 2 and Figure 4 , the smaller grinding gap is suitable for producing bean product raw material powder with finer particle size, while the larger gap is suitable for preliminary grinding or processing products with low particle size requirement, thereby meeting the diversified production requirements. The outer diameter of the grinding disc 2 increases from top to bottom, so that the grinding gap decreases from top to bottom. With the rotation of the grinding disc 2, the raw material gradually moves downward and is extruded and ground by different diameter parts, so that the raw material is first subjected to preliminary grinding and then refined, which is beneficial to improving the grinding efficiency.

[0047] As shown in Figure 2 and Figure 3 ,As shown, the inner lifting cylinder 7 is connected with the lower feeding cylinder 73 sliding up and down, the axis of the lower feeding cylinder 73 coincides with the axis of the inner lifting cylinder 7, and the lower feeding cylinder 73 is located below the feeding hopper 11. The lower feeding cylinder 73 and the inner lifting cylinder 7 are both provided with clamping grooves which are in sliding cooperation with each other, so as to realize the relative sliding of the lower feeding cylinder 73 and the inner lifting cylinder 7.

[0048] As shown in Figure 2 and Figure 3 , the shaft 5 is provided with a guide plate 52 below the stirring blade, and the upper end face and the lower end face of the guide plate 52 are both conical. That is, the diameter of the upper end face of the guide plate 52 increases from top to bottom, and the diameter of the lower end face of the guide plate 52 decreases from top to bottom.

[0049] As shown in Figure 2 and Figure 3 , the guide plate 52 is located in the lower feeding cylinder 73, and the inner wall of the lower feeding cylinder 73 is provided with an annular feeding plate 731 which is inclined from top to bottom to the direction close to the axis of the lower feeding cylinder 73. There is a feeding gap between the guide plate 52 and the lower feeding cylinder 73, and between the lower end face of the guide plate 52 and the feeding plate 731.

[0050] As shown in Figure 2 and Figure 3 , the raw materials are transported into the shell 1 through the feeding hopper 11, and under the pushing action of the helical blade 51, it is beneficial to the uniform falling of the raw materials on the guide plate 52 and along the feeding gap, which helps to reduce the phenomenon of local accumulation of raw materials, thereby improving the grinding effect and reducing the local temperature rise caused by local accumulation.

[0051] As shown in Figure 2 and Figure 4 , the shaft 5 is connected with a plurality of crushing rings 53 below the guide plate 52, and the crushing rings 53 are provided with a plurality of crushing knives 531. The upper and lower crushing rings 53 and the guide plate 52 are connected with return springs 532, and the return springs 532 are columnar springs which are sleeved on the shaft 5. The crushing rings 53 and the inner wall of the lower feeding cylinder 73 form a crushing cavity.

[0052] As shown in Figure 2 and Figure 4 , the plurality of crushing rings 53 are distributed along the axis of the shaft 5, forming a multi-stage crushing structure. After the crushing of the raw materials by the crushing knives 531 on the crushing rings 53, the size of the raw materials is reduced, which is beneficial to improve the quality of subsequent grinding and reduce the temperature rise during grinding.

[0053] As shown in Figure 2 and Figure 4As shown, in order to improve the crushing effect, the blade surface of the crushing blade 531 is provided with a convex rib. The upper and lower crushing rings 53 are connected through the reset spring 532, so that the gap between the crushing rings 53 can be automatically adjusted according to the flow and particle size of the raw materials, which is also beneficial to improve the crushing effect.

[0054] As shown in Figure 2 and Figure 4 , a shaft sleeve 54 is sleeved below the crushing ring 53 on the rotating shaft 5, and the shaft sleeve 54 and the rotating shaft 5 can relatively slide and rotate. The upper end of the shaft sleeve 54 is connected with a sieve plate 55, and the surface of the sieve plate 55 can abut against the crushing blade 531.

[0055] As shown in Figure 2 and Figure 4 , the raw materials crushed by the crushing blade 531 fall to the sieve plate 55, and the sieve plate 55 can screen out fine particles meeting the particle size requirement, so that they pass through the sieve hole into the subsequent grinding area, which is beneficial to improve the grinding quality. The large particles that do not meet the particle size standard are intercepted on the sieve plate 55, and the crushing blade 531 continues to crush them.

[0056] As shown in Figure 2 and Figure 3 , in the process of crushing the raw materials by the crushing blade 531, the raw materials will splash, and the lower end surface of the guide plate 52 is also designed as a conical surface. In the process of colliding with the lower end surface of the guide plate 52, the splashed raw materials are diffused to the edge through the rebound and gravity effect, and then fall into the crushing cavity from the discharging gap, which is beneficial to increase the dispersion of the raw materials and reduce the phenomenon of excessive temperature caused by local accumulation of the raw materials.

[0057] As shown in Figure 4 and Figure 5 , a uniform distribution disc 56 is sleeved on the shaft sleeve 54, the uniform distribution disc 56 is located below the sieve plate 55 and above the grinding disc 2, the uniform distribution disc 56 is connected to the grinding disc 2, and a plurality of arc-shaped uniform distribution plates 561 are arranged on the uniform distribution disc 56. The uniform distribution disc 56 and the discharging cylinder 73 and the lifting inner cylinder 7 are all left with gaps for the raw materials to fall.

[0058] As shown in Figure 4 and Figure 5 , the raw materials falling from the sieve plate 55 fall on the uniform distribution disc 56, the grinding disc 2 drives the uniform distribution disc 56 to rotate, and the arc-shaped uniform distribution plates 561 on the uniform distribution disc 56 rotate synchronously with the uniform distribution disc 56, which has a guiding and shunting effect on the falling raw materials, which is beneficial to uniformly disperse the raw materials to the grinding surface of the grinding disc 2, reduce the local accumulation of the raw materials on the grinding disc 2, improve the grinding effect, and also reduce the local temperature rise caused by local accumulation.

[0059] As shown in Figure 4 , Figure 6 andFigure 7 As shown, the outer wall of the shaft sleeve 54 and the middle part of the uniform distribution disc 56 are provided with sawtooth-shaped inclined blocks 57 in sliding fit with each other. With the rotation of the uniform distribution disc 56, the shaft sleeve 54 can be lifted and lowered under the sliding fit of the inclined surfaces of the two inclined blocks 57, the shaft sleeve 54 drives the sieve plate 55 to lift and lower, which is beneficial to reduce the blockage of the sieve holes on the sieve plate 55.

[0060] As shown in Figure 3 and Figure 4 , the blanking cylinder 73 is connected with the lifting inner cylinder 7 through a reset spring 74, the edge of the uniform distribution plate 561 on the uniform distribution disc 56 can abut against the blanking cylinder 73, the inner wall of the blanking cylinder 73 is provided with a plurality of sliding grooves 732 in the vertical direction, the edge of the sieve plate 55 is provided with a plurality of abutting plates 551 in intervals, and the number of the abutting plates 551 is consistent with the number of the sliding grooves 732. The abutting plate 551 can slide up and down in the sliding groove 732 and abut against the upper edge and the lower edge of the sliding groove 732.

[0061] As shown in Figure 3 , Figure 4 and Figure 6 , the sliding groove 732 plays a guiding role in the up and down movement of the abutting plate 551, and limits the rotation of the sieve plate 55 and the shaft sleeve 54, so that the shaft sleeve 54 can lift and lower under the sliding fit of the two inclined blocks 57. When the sieve plate 55 moves upward with the shaft sleeve 54, the abutting plate 551 can slide in the sliding groove 732 and abut against the upper edge of the sliding groove 732, so as to drive the sliding groove 732 and the blanking cylinder 73 to move upward, and the reset spring 74 is compressed.

[0062] As shown in Figure 3 and Figure 4 , when the sieve plate 55 moves downward with the shaft sleeve 54, the blanking cylinder 73 loses the upward lifting force of the sieve plate 55, and under the action of the gravity of the blanking cylinder 73 itself and the elastic force of the reset spring 74, the blanking cylinder 73 is beneficial to stably fall, and in turn the sieve plate 55 is beneficial to stably fall under the guidance and constraint of the gravity and the sliding groove 732.

[0063] As shown in Figure 2 and Figure 4 , the upper end of the grinding disc 2 is provided with an annular groove 21, the groove wall of the annular groove 21 is provided with a step one 211, and the lower end surface of the uniform distribution disc 56 is provided with a step two 562, so that the edge of the uniform distribution disc 56 is connected with the edge of the grinding disc 2, and a cavity is left between the uniform distribution disc 56 and the grinding disc 2.

[0064] As shown in Figure 2 and Figure 4 , the annular groove 21 is rotatably and slidingly connected with a sealing plate 22, a liquid outlet cavity is left between the grinding disc 2, the sealing plate 22 and the uniform distribution disc 56, and a plurality of one-way valves 221 are installed on the sealing plate 22.

[0065] As shown in Figure 2 andFigure 4 As shown in the drawings, the grinding disc 2 is provided with a plurality of 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 driving shaft 31.

[0066] As shown in the drawings, Figure 2 and Figure 4 the lower part of the grinding disc 2 is rotationally connected with a liquid storage cavity 8, and the liquid storage cavity 8 is rotationally connected with the driving shaft 31. The lower part of the liquid inlet channel 23 is provided with a liquid inlet pipeline 25, and the lower end of the liquid inlet pipeline 25 extends into the bottom of the liquid storage cavity 8. The liquid storage cavity 8 is communicated with the annular groove 21 through the liquid inlet channel 23, and the liquid outlet cavity is communicated with the liquid storage cavity 8 through the liquid outlet channel 24.

[0067] As shown in the drawings, Figure 2 and Figure 4 the shaft sleeve 54 drives the sealing plate 22 to ascend and descend, so as to control 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 rises, which pushes the valve core of the one-way valve 221 to overcome the resistance of the spring, so that the valve core is opened, and the cooling liquid in the annular groove 21 enters the liquid outlet cavity through the one-way valve 221. When the sealing plate 22 ascends, the cooling liquid in the liquid outlet cavity enters the liquid storage cavity 8 through the liquid outlet channel 24, the hydraulic pressure in the liquid storage cavity 8 rises, and the cooling liquid in the liquid storage cavity 8 enters the annular groove 21 through the liquid inlet pipeline 25 and the liquid inlet channel 23 in sequence, so as to realize the circulation of the cooling liquid in sequence.

[0068] As shown in the drawings, Figure 2 and Figure 4 the liquid storage cavity 8 is arranged in the base 3, one side of the liquid storage cavity 8 is connected with a liquid inlet pipe 81 penetrating through the base 3, and the other side of the liquid storage cavity 8 is connected with a liquid outlet pipe 82 penetrating through the base 3.

[0069] As shown in the drawings, Figure 1 and ​ the cooling liquid is transported into the liquid storage cavity 8 through the liquid inlet pipe 81, and the heated cooling liquid in the liquid storage cavity 8 is output through the liquid outlet pipe 82, so as to realize the replacement of the cooling liquid, and the circulation of the cooling liquid can take away the heat, so as to cool the grinding disc 2 and the raw materials in the shell 1, which is beneficial to reduce the phenomenon that the nutrients of the raw materials are lost or deteriorated due to the excessively high temperature in the shell 1.

[0070] As shown in the drawings, ​ one side of the shell 1 is provided with a discharge pipe 13, a three-way valve 14 is installed on the discharge pipe 13, the three-way valve 14 is connected with a circulating pipe 15, and the circulating pipe 15 extends into the feeding hopper 11. The raw materials discharged from the discharge pipe 13 may have some particles which are not completely processed, and these particles are sent back to the feeding hopper 11 through the circulating pipe 15, so as to re-enter the processing flow until the preset fineness is reached.

[0071] The implementation principle of the grinding device for processing bean product raw materials in the embodiment is as follows: The driving motor 4 drives the driving shaft 31 and the rotating shaft 5 to rotate, and the raw materials are conveyed into the feeding hopper 11. Under the conveying action of the spiral blade 51, the raw materials are uniformly conveyed to the guide plate 52. Under the guiding action of the guide plate 52, the raw materials fall into the crushing cavity along the discharging gap, and the crushing knife 531 crushes the raw materials. The crushed raw materials fall onto the sieve plate 55.

[0072] The raw materials meeting the particle size requirement pass through the sieve holes into the subsequent grinding area, and the large particles not meeting the particle size standard are intercepted on the sieve plate 55, and the crushing knife 531 continues to crush them. In the process of crushing the raw materials, the raw materials will splash. In the process of colliding with the lower end surface of the guide plate 52, the splashed raw materials will spread to the edge through the rebound and gravity action, which is beneficial to increase the dispersion of the raw materials and reduce the phenomenon of excessive temperature caused by local accumulation of the raw materials.

[0073] The driving shaft 31 drives the grinding disc 2 and the uniform distribution disc 56 to rotate. The raw materials falling from the sieve plate 55 fall on the uniform distribution disc 56. When the arc-shaped uniform distribution plate 561 on the uniform distribution disc 56 rotates synchronously with the uniform distribution disc 56, it produces a guiding and shunting effect on the falling raw materials, which is beneficial to uniformly disperse the raw materials to the grinding surface of the grinding disc 2 and reduce the local accumulation of the raw materials on the grinding disc 2.

[0074] The grinding disc 2 grinds the raw materials. The ground raw materials are discharged from the discharge pipe and sent back to the feeding hopper 11 through the circulating pipe 15 for repeated grinding to achieve the preset fineness.

[0075] In the process of rotating, the uniform distribution disc 56 drives the shaft sleeve 54 to rise and fall through the inclined surface sliding fit of the two inclined blocks 57 on the uniform distribution disc 56 and the shaft sleeve 54. The shaft sleeve 54 drives the sieve plate 55 and the sealing plate 22 to rise and fall. The rising and falling of the sieve plate 55 is beneficial to reduce the blockage of the sieve holes on the sieve plate 55.

[0076] When the sealing plate 22 descends, the one-way valve 221 opens, and the cooling liquid in the annular groove 21 enters the liquid outlet cavity through the one-way valve 221. When the sealing plate 22 rises, the one-way valve 221 closes, and the cooling liquid in the liquid outlet cavity enters the liquid storage cavity 8 through the liquid outlet channel 24. The hydraulic pressure in the liquid storage cavity 8 rises, and the cooling liquid in the liquid storage cavity 8 enters the annular groove 21 through the liquid inlet pipeline 25 and the liquid inlet channel 23 in turn, realizing the circulation of the cooling liquid in turn. The circulation of the cooling liquid can take away heat and cool the raw materials in the grinding disc 2 and the shell 1, which is beneficial to reduce the phenomenon that the high temperature in the shell 1 causes the loss or deterioration of the nutrients of the raw materials.

[0077] In addition, it needs to be explained that in the description of the present application, unless explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the internal communication of two elements.
