Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a grinding device with a cooling system and a method for grinding soapberry rice into flour. Background Technology

[0002] Soapberry rice, the fruit of a deciduous tree belonging to the genus *Gleditsia* in the legume family, has broad application prospects in the food, health product, and cosmetic fields due to its unique nutritional value and medicinal effects. In recent years, with the popularization of healthy eating concepts, consumers' demand for natural, additive-free, and highly nutritious foods has been continuously increasing. As a high-energy, low-protein, and low-fat green food, soapberry rice, when ground into powder, is easier to store, carry, and consume, meeting modern people's demand for convenient and healthy foods.

[0003] Chinese invention patent application number CN201922102038.0 discloses a soapberry pulverizer specifically for producing oryzanol. The pulverizer includes a machine body and a top cover. The top cover is hinged to the top of the machine body, and one end of the top cover is movably connected to an electric telescopic rod via a pin. The other end of the electric telescopic rod is connected to the side wall of the machine body via a pin. During pulverization, the pulverizer uses a connecting rod to push a pressure plate downwards, increasing the contact area between the soapberry and the pulverizing paddle, thus effectively improving the pulverization efficiency. A heater can heat the soapberry powder, thereby drying it. A glass cover is embedded in the cavity wall of the machine body. The glass cover has a double-layer structure, and a vacuum layer is set inside the glass cover, which effectively reduces heat loss, improves the drying efficiency of the soapberry powder, and the vacuum layer prevents sound transmission, thus reducing noise generation during soapberry pulverization.

[0004] While current technology can effectively improve the crushing efficiency of soapberry by increasing the contact area between the soapberry and the crushing paddle, it still faces multiple challenges when grinding soapberry rice into powder. This is mainly because soapberry rice has a high content of gum, which easily generates high temperatures during crushing and grinding, causing the gum to stick together and making it difficult to achieve the ideal fine powder state.

[0005] Furthermore, although the standard process includes a sieving device at the discharge port to filter the powder in the grinding process, the low mesh size of the sieves often leads to sieve blockage in soapberry rice flour, directly affecting the smoothness and efficiency of the discharge. Even more serious is the gradual accumulation of insufficiently ground material at the bottom of the grinding components and the bottom of the container after prolonged operation. This not only restricts the normal operation of the grinding components and reduces the grinding quality, but may also cause irreversible damage to the equipment structure.

[0006] Meanwhile, the adhesion of materials to the grinding components also deserves serious attention. This adhesion not only further deteriorates the grinding effect but may also cause the grinding components to jam due to excessive load, thereby severely restricting production efficiency and equipment lifespan.

[0007] In summary, to solve the core problems such as adhesive adhesion, screen clogging, material accumulation and adhesion that occur during the grinding of saponin rice flour, it is urgent to develop a grinding device with a cooling system and a method for grinding saponin rice flour to ensure a smooth and efficient production process and stable product quality.

[0023] A method for preparing soapberry rice flour using a grinding device with a cooling system, the method comprising the following steps:

[0024] S1. Pre-treatment and preliminary crushing of saponin rice: First, the saponin rice is dried to ensure it reaches a dry state. The dried saponin rice is then fed into a crusher. The crusher performs preliminary crushing to prepare for subsequent grinding operations.

[0025] S2. Grinding of crushed soapberry rice: After the soapberry rice is crushed, the crushed soapberry rice is introduced into the installation cylinder assembly through the feed inlet. Then, the grinding assembly is started to perform fine grinding of the crushed soapberry rice in the installation cylinder assembly to prepare the required powder product.

[0026] S3. Circulating grinding improves efficiency and quality. During the grinding process, the circulation component is started simultaneously.

[0028] The technical effects and advantages of this invention are as follows:

[0029] 1. This invention, by incorporating temperature and flow sensors, enables real-time monitoring of the temperature between the moving housing and the grinding section, as well as the flow rate on the sieve plate, ensuring the stability and safety of equipment operation. When the temperature or flow rate exceeds a preset threshold, the control system automatically adjusts the grinding process. Specifically, it reduces the flow rate of saponin rice by adjusting the deflection of the adjustment components, coordinating with the vacuum conveyor for circulating grinding. This effectively prevents overheating and blockage, improving grinding efficiency and product quality.

[0030] 2. This invention, by setting up a screening plate and a conveying auger, effectively removes blockages on the screening plate through periodic collisions and spiral impacts, enhancing the self-cleaning ability of the screening plate and reducing the need for manual maintenance. At the same time, the inverted conical design at the bottom of the movable shell, combined with the spiral downward impact of the soapberry rice, ensures that the upper and lower surfaces of the screening plate are continuously impacted, improving screening efficiency and ensuring smooth product discharge.

Detailed Implementation

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] Reference Figures 1 to 12As shown, the present invention provides a grinding device with a cooling system, including a mounting cylinder assembly 1. A sieving device 8 and a pulverizing device 9 are respectively provided on both sides of the mounting cylinder assembly 1. A powder storage 10 is provided on the outside of the sieving device 8. The mounting cylinder assembly 1 includes a fixed shell 101. A movable shell 102 is provided on the outside of the fixed shell 101. A pushing member 103 is provided between the fixed shell 101 and the movable shell 102. The pushing member 103 drives the movable shell 102 to reciprocate on the outside of the fixed shell 101.

[0046] The pusher 103 includes a hydraulic push rod. The fixed end of the hydraulic push rod is connected to a fixed ring plate disposed around the fixed housing 101, and the output end of the hydraulic push rod is connected to a movable ring plate fixedly connected around the movable housing 102. By controlling the pusher 103 to start, the output end of the pusher 103 pushes the movable housing 102 to move downward, so that the bottom of the movable housing 102 contacts the conveying assembly 4.

[0047] A bracket (not shown in the figure) is provided on the outside of the fixed housing 101, which fixes the fixed housing 101 at a set height.

[0048] The interior of the mounting cylinder assembly 1 is provided with a grinding assembly 2, and the outside of the grinding assembly 2 is provided with an adjustment assembly 6. The adjustment assembly 6 is used to adjust the way the soapberry rice enters the grinding assembly 2 and the movable housing 102.

[0049] The bottom of the grinding component 2 and the bottom of the fixed housing 101 together form a grinding space. After the soapberry rice enters the installation cylinder component 1 through the feed port 7, as the grinding component 2 continues to rotate, the soapberry rice gradually enters the grinding space between the grinding component 2 and the movable housing 102, and the grinding component 2 performs grinding operations on the soapberry rice that has entered the grinding space.

[0050] The mounting cylinder assembly 1 is provided with a circulation assembly 3 on its periphery. The two ends of the circulation assembly 3 are respectively connected to the fixed housing 101 and the movable housing 102. The circulation assembly 3 is used to drive the soapberry rice to circulate inside the mounting cylinder assembly 1.

[0051] While the grinding component 2 is grinding the saponin rice, the circulation component 3 is started simultaneously. The circulation component 3 extracts some of the saponin rice that has entered the grinding space from the grinding space and puts it back into the installation cylinder component 1, where the grinding component 2 grinds it again, thus improving the grinding effect of the saponin rice.

[0052] The top of the mounting cylinder assembly 1 is connected to the conveying assembly 4 via the connecting assembly 5. The connecting assembly 5 performs sieving of the soapberry rice flour, and the conveying assembly 4 is used to transport the soapberry rice flour that has completed the grinding operation to the next process.

[0053] Reference Figure 4As shown, the grinding assembly 2 includes a drive device 201, which is disposed on the top of the fixed housing 101. A transmission shaft 202 is provided on the output shaft of the drive device 201. The transmission shaft 202 is located inside the fixed housing 101. A grinding part 203 is provided at the end of the transmission shaft 202 away from the drive device 201. An array of mounting grooves 204 are provided on the outer surface of the grinding part 203. An adjustment component 6 is provided inside each mounting groove 204.

[0054] The drive device 201 includes a drive motor, which is connected to the top of the fixed housing 101 via a motor mount. After the drive device 201 is started, it drives the grinding part 203 to rotate via a transmission shaft 202. The grinding part 203 grinds the saponin rice that has entered the grinding space.

[0055] Reference Figures 4 to 11 As shown, the grinding part 203 has a regular octagonal cross section. The bottom of the grinding part 203 is provided with a first grinding surface 2031, and the middle part of the grinding part 203 is provided with a second grinding surface 2032. The first grinding surface 2031 is in contact with the bottom surface of the movable housing 102, and the adjustment component 6 is provided on the second grinding surface 2032.

[0056] Reference Figures 1 to 5 As shown, the circulation component 3 includes a material pipe 301. One end of the material pipe 301 is in contact with the bottom of the movable housing 102, and the other end of the material pipe 301 is connected to a vacuum conveyor 302. The end of the vacuum conveyor 302 away from the material pipe 301 is connected to the top of the fixed housing 101.

[0057] The vacuum conveyor 302 is started. The vacuum conveyor 302 extracts the saponin rice that has entered the grinding space from the grinding space through the material pipe 301 and puts it back into the fixed housing 101. The grinding part 203 then grinds it again to improve the grinding effect of the saponin rice.

[0058] Vacuum conveyor 302 is a device that uses a pneumatic pump to generate airflow and uses a pipeline system to pick up and transport materials to a target location. Using vacuum conveyor 302 to transport materials is existing technology and will not be described in detail here.

[0059] The vacuum conveyor 302 is provided with an air supply pipe 303 on its outer side. The end of the air supply pipe 303 away from the vacuum conveyor 302 is provided with a circulating air pump 304, which is connected to the top of the fixed housing 101.

[0060] Reference Figures 5 to 8As shown, the adjustment component 6 includes a connecting rod 601 disposed inside the mounting groove 204. Both ends of the connecting rod 601 are provided with telescopic portions 602. The end of the telescopic portion 602 away from the connecting rod 601 is provided with a hinge portion 603. The outer side of the hinge portion 603 is provided with a pushing portion.

[0061] The pushing part includes an electric push rod. By controlling the upper and lower pushing parts of the connecting rod 601 to retract with different amounts of extension and retraction, the connecting rod 601 can be deflected.

[0062] The outer side of the connecting rod 601 is provided with an array of adaptable parts 605, and both ends of the connecting rod 601 are provided with connecting discs 604, which are in contact with the outer side of the adaptable parts 605.

[0063] Reference Figures 5 to 8 As shown, the adaptation part 605 includes a rotating part 6051. The inner side of the rotating part 6051 is rotatably connected to the outer side of the connecting rod 601. An array of elastic connecting members 6052 are provided on the outer side of the rotating part 6051. The end of the elastic connecting members 6052 away from the rotating part 6051 is connected to a connecting ring 6053.

[0064] The connecting rings 6053 distributed on the connecting rod 601 are in contact with each other, and the connecting plate 604 shields the area between the rotating part 6051 and the connecting rings 6053.

[0065] The elastic connector 6052 includes a spring. One end of the spring is fixedly connected to the outer side of the rotating part 6051, and the other end of the spring is fixedly connected to the inner ring of the connecting ring 6053. A pressure sensor is provided at the connection between the spring and the rotating part 6051. The pressure sensor is used to detect the elastic expansion and contraction of the elastic connector 6052. By detecting the specific value of the pressure sensor, it can be determined whether the material inside the mounting cylinder assembly 1 has completed the grinding operation.

[0066] It should be noted that during the grinding process of the grinding unit 203 on the soapberry rice, the first grinding surface 2031 is the main grinding surface, which performs the grinding operation of the corresponding mesh size through the gap between it and the bottom of the movable housing 102 (the size of the gap can be controlled by the extension and retraction of the pusher 103). The second grinding surface 2032 is the secondary grinding surface, which performs the corresponding auxiliary grinding operation through the extrusion between the adjusting component 6 and the inside of the movable housing 102.

[0067] Reference Figures 1 to 2 As shown, the conveying assembly 4 includes a body 401, a discharge pipe 402 at the bottom of the body 401, a connecting part 404 at the top of the body 401, the connecting part 404 being connected to the connecting assembly 5, and a conveying auger 403 inside the body 401, the spiral part of the conveying auger 403 being higher than the bottom of the connecting part 404.

[0068] One end of the conveying auger 403 is equipped with a drive motor. When the drive motor is started, it drives the conveying auger 403 to rotate. During the rotation of the conveying auger 403, the soapberry rice flour that has completed the grinding operation is conveyed to the next process.

[0069] Reference Figures 1 to 5 As shown, the connecting component 5 includes a telescopic conveying pipe 501. One end of the telescopic conveying pipe 501 is connected to the connecting part 404, and the other end of the telescopic conveying pipe 501 is provided with a screening plate 502. The screening plate 502 is fixedly connected to the bottom of the fixed housing 101.

[0070] During the process of the pusher 103 pushing the fixed housing 101 downward, the fixed housing 101 pushes the screening plate 502 downward, so that the screening plate 502 comes into contact with the bottom surface of the connecting part 404, and the spiral part of the conveying auger 403 can make intermittent contact impact with the bottom surface of the screening plate 502, so that the blockage of the screening plate 502 is cleared.

[0071] A flow sensor is installed on the screening plate 502 to detect whether the screening plate 502 is blocked.

[0072] A temperature sensor is provided at the bottom of the movable housing 102. The temperature sensor is used to detect whether the temperature between the movable housing 102 and the grinding part 203 is too high.

[0073] A pressure sensor is provided at the connection between the elastic connector 6052 and the rotating part 6051. The pressure sensor is used to detect the elastic expansion and contraction of the elastic connector 6052.

[0074] A control terminal is provided on the outside of the fixed housing 101, and a control system is provided inside the control terminal. The control system is used to control the movement of all electrical components on this device.

[0075] In the initial state, the connecting rod 601 and the bottom of the mounting groove 204 are perpendicular to each other.

[0076] The process of preparing soapberry rice into soapberry rice flour mainly includes the following steps:

[0077] First, the saponin rice is thoroughly sun-dried to ensure it is completely dry, which is the foundation for the smooth progress of the entire processing. After drying, the saponin rice is fed into a grinder for preliminary grinding, a step designed to transform it into a raw material suitable for further fine processing.

[0078] After the soapberry rice is crushed, it is transported to the inside of the feed inlet 7 by a conveying device. The feed inlet 7 then transports the crushed soapberry rice into the inside of the fixed shell 101.

[0079] After the saponin rice enters the fixed housing 101, the control system starts the drive device 201. The drive device 201 drives the grinding part 203 to rotate through the transmission shaft 202. During the rotation of the grinding part 203, the saponin rice gradually enters the grinding space between the grinding part 203 and the movable housing 102 under the influence of centrifugal force. The grinding part 203 then grinds the saponin rice that has entered the grinding space.

[0080] During the grinding process, the first grinding surface 2031 and the second grinding surface 2032 on the grinding unit 203 work together to finely grind the saponin rice. In order to optimize the grinding efficiency and prevent overheating, the control system starts the vacuum conveyor 302 in a timely manner. The vacuum conveyor 302 extracts the saponin rice that has entered the grinding space through the material pipe 301 and returns it to the inside of the fixed shell 101. Then, the grinding unit 203 performs secondary grinding. This avoids putting too much saponin rice into the grinding space at one time, which would cause the grinding unit 203 to be overloaded during operation and result in excessive temperature between the first grinding surface 2031 and the bottom of the movable shell 102. This ensures the smooth progress of the grinding operation and the high-quality output of the product.

[0081] After the grinding process is completed, the saponin rice flour that meets the predetermined mesh size passes through the sieve plate 502 installed at the bottom of the movable housing 102 and enters the internal space of the machine body 401. Then, the conveying auger 403 built into the machine body 401 is started. The conveying auger 403 transports the saponin rice flour along the predetermined path to the discharge pipe 402 on the machine body 401. The discharge pipe 402 discharges the saponin rice flour for further processing in the next process.

[0082] During the grinding process, the control system monitors two key parameters in real time: the flow rate sensor on the sieve plate 502, which accurately measures the amount of soapberry rice flour passing through; and the temperature sensor at the bottom of the movable housing 102, which closely monitors temperature changes within the grinding space. By comprehensively analyzing these two parameters, the control system can accurately determine the specific conditions within the grinding space between the bottom of the movable housing 102 and the grinding section 203. Based on this determination, the control system adjusts the mounting cylinder assembly 1 and the regulating assembly 6 to quickly adapt to changes within the grinding space, thereby ensuring a stable and efficient grinding process.

[0083] When the control system detects that the reading of the temperature sensor at the bottom of the movable housing 102 exceeds the preset threshold, while the value of the flow sensor on the sieve plate 502 remains stable, it indicates that excessive saponin rice has accumulated between the first grinding surface 2031 and the bottom of the movable housing 102, resulting in an excessive workload on the grinding section 203, which in turn causes the temperature between the first grinding surface 2031 and the bottom of the movable housing 102 to be too high.

[0084] To address this situation, the control system immediately activated the adjustment component 6 within the movable slot to perform structural adjustments. The two originally parallel adjacent adjustment components 6 were transformed into an interleaved state (specifically as follows...). Figure 9 As shown, this change effectively reduces the channel between the regulating components 6 and the bottom of the first grinding surface 2031 and the movable housing 102, forcing the saponin rice to temporarily linger in the conical space formed by the two regulating components 6, reducing the flow rate of saponin rice directly into the grinding area, and also alleviating the problem of excessive temperature in the grinding section 203 caused by excessive saponin rice.

[0085] At the same time, the circulation component 3 continues to operate, continuously extracting saponin rice from the bottom of the movable housing 102. This dual measure further reduces the amount of saponin rice flowing to the grinding surface, thereby more effectively controlling the temperature between the first grinding surface 2031 and the bottom of the movable housing 102 and preventing overheating.

[0086] The specific operation process for changing the two originally parallel adjacent adjustment components 6 into an interleaved state is as follows:

[0087] Assume that the two adjacent regulating components 6 are regulating component A and regulating component B.

[0088] First, the two pushing parts on the connecting rod 601 associated with the A adjustment component extend synchronously. These two pushing parts are centrally symmetrically distributed on the connecting rod 601. During the extension process, the pushing parts apply a rightward torque to the connecting rod 601 through the hinge 603, causing the connecting rod 601 to deflect clockwise. At the same time, in order to ensure smooth deflection, the telescopic part 602 on the connecting rod 601 also extends synchronously to counteract any obstruction that the hinge 603 may cause, ensuring that the deflection process is not affected.

[0089] While adjusting component A deflects, it controls the two pushing parts on the connecting rod 601 corresponding to adjusting component B to retract synchronously. This action causes the connecting rod 601 of adjusting component B to be subjected to a force to the left, thereby causing it to deflect in a counterclockwise direction.

[0090] Through the above steps, regulating components A and B change from a parallel state to an interlaced state. This structural change effectively adjusts the flow path of materials (such as soapberry rice), reducing the amount of material flowing directly into the grinding zone, thereby helping to control the temperature during the grinding process.

[0091] It is important to note that during the transition of adjustment component 6, when the connecting rod 601 deflects, the connecting rings 6053 distributed on the connecting rod 601 are pressed against the inner wall of the movable housing 102. This pressing action, buffered and guided by the elastic connector 6052, causes the connecting rings 6053 to undergo a deflection. This displacement is designed to ensure that the adapting parts 605 on the connecting rod 601, which might otherwise hinder its rotation, can smoothly avoid this obstruction during the deflection process. This design not only ensures the smoothness of the deflection of the connecting rod 601 but also enhances the flexibility and adaptability of the entire adjustment system. This dynamic interaction between the connecting rings 6053 and the fixed housing 101, along with the effective intervention of the elastic connector 6052, together constitute an efficient and stable adjustment mechanism, enabling adjustment components A and B to smoothly transition from a parallel state to an interleaved state, thereby meeting various complex process requirements.

[0092] When the control system detects that the temperature sensor reading at the bottom of the movable housing 102 exceeds the preset safety threshold, and at the same time the flow sensor data on the sieve plate 502 also exceeds the preset safety threshold, this combination indicates that an abnormally high temperature has occurred between the first grinding surface 2031 and the bottom of the movable housing 102. This high temperature is likely due to the soapberry rice flour becoming sticky due to excessive heating, which in turn causes the sieve plate 502 to become clogged.

[0093] When the control system detects that the sieve plate 502 is clogged due to the sticky residue of the soapberry rice flour, it immediately controls the operation of the pusher 103 and the adjusting component 6. The pusher 103 causes the movable housing 102 to move downward, disengaging its bottom from the grinding section 203, and simultaneously driving the sieve plate 502 downward. During this process, the sieve plate 502 compresses the telescopic conveyor tube 501 until it is completely moved to the bottom of the connecting section 404. Because the spiral section of the conveying auger 403 is designed to be higher than the bottom of the connecting section 404 (specifically as shown in the figure), the sieve plate 502 is lower than the bottom of the connecting section 404. Figure 2 As shown, after the screening plate 502 reaches the bottom, the conveying auger 403 will intermittently strike its lower surface, causing the screening plate 502 to vibrate and effectively remove the soapberry rice flour that is blocked in the mesh. Because of the sticky adhesive, these rice flours are large in volume and cannot fall into the conveying component 4 naturally through the mesh. Therefore, after being struck by the auger, they are also prompted to move along the periphery of the screening plate 502. Finally, under the suction of the material pipe 301, they are guided to the top of the grinding section 203 for secondary grinding.

[0094] Meanwhile, during the extraction of soapberry rice flour by the material pipe 301, the control system synchronously drives the adjustment component 6 to deflect, so that the deflection direction of the top of the adjustment component 6 is opposite to the rotation direction of the grinding section 203 (specifically as follows). Figure 10(As shown). This is intended to allow the adjusting component 6 to collide with the second grinding surface 2032 when the saponin rice flour passes through it, slowing its falling speed and providing additional grinding action to enhance the refining effect on the saponin rice.

[0095] The specific operation process for adjusting the deflection direction of the top of component 6 to be opposite to the rotation direction of the grinding part 203 is as follows:

[0096] Assuming the grinding section 203 rotates clockwise, when the adjustment component 6 needs to be deflected, the two pushing parts on the connecting rod 601 associated with the adjustment component 6 extend synchronously. These two pushing parts are centrally symmetrically distributed on the connecting rod 601. Therefore, during the extension process, they apply a rightward torque to the connecting rod 601 through the hinge 603, causing the connecting rod 601 to deflect clockwise. After the connecting rod 601 deflects clockwise, the top of the connecting rod 601 is in the opposite direction to the rotation of the grinding section 203.

[0097] It is particularly important to note that during the extraction of soapberry rice flour by the material pipe 301, the first grinding surface 2031 of the grinding section 203 is separated from the bottom of the movable housing 102. This operation allows the material pipe 301 to not only extract the material accumulated around the sieve plate 502, but also to extract the air between the grinding section 203 and the bottom of the movable housing 102, as well as the air inside the machine body 401. This dual effect significantly accelerates the airflow between the grinding section 203 and the bottom of the movable housing 102, thereby indirectly achieving a cooling effect on the bottom of the movable housing 102, which helps maintain the working efficiency and stability of the equipment. When the material pipe 301 extracts air from the machine body 401, the air inside the machine body 401 enters the area between the grinding section 203 and the bottom of the movable housing 102 through the sieve plate 502. After entering the area between the grinding section 203 and the bottom of the movable housing 102, the gas impacts the bottom of the grinding section 203, thus cleaning the material adhering to the grinding section 203.

[0098] Once the temperature of the movable housing 102 stabilizes within the normal range, the control system immediately commands the pusher 103 and the adjusting component 6 to return to their standard operating state. If, after this, the value monitored by the flow sensor on the sieve plate 502 still exceeds the preset safety threshold, it indicates that the soapberry rice flour adhering to the sieve plate 502 has not been completely removed. At this time, the control system will immediately initiate countermeasures, driving the pusher 103 to extend and retract, causing the bottom of the sieve plate 502 to periodically collide with the spiral part of the conveying auger 403; simultaneously, the control system adjusts the deflection direction of the adjusting component 6 to form a relative position with the rotation direction of the grinding section 203 (specifically as follows). Figure 11(As shown). As the grinding section 203 continues to rotate, the saponin rice is accelerated by the deflection direction of the adjusting component 6 and moves downward along the spiral path. Since the bottom of the movable housing 102 is designed with an inverted conical structure, the downward-moving saponin rice can effectively impact the top of the screening plate 502 in a spiral manner. This continuous impact from both the top and bottom greatly enhances the anti-clogging and self-cleaning function of the screening plate 502 and improves the overall screening efficiency.

[0099] This invention, by setting up an adjustment component 6 and a pusher 103, can monitor the temperature between the movable housing 102 and the grinding section 203 and the flow rate on the sieve plate 502 in real time through a temperature sensor at the bottom of the movable housing 102 and a flow sensor on the sieve plate 502. By changing the deflection direction of the adjustment component 6 and the extension / retraction state of the pusher 103, the material flow path and grinding effect are optimized, ensuring the stability and safety of the equipment operation. When excessive accumulation of saponin rice is detected, the parallel adjustment component 6 is adjusted to an interlaced state, narrowing the channel for saponin rice to flow into the grinding zone, reducing the flow rate of saponin rice, and lowering the temperature between the first grinding surface 2031 and the bottom of the movable housing 102. When blockage of the sieve plate 502 is detected, the pusher 103 drives the sieve plate 502 to vibrate and clear the blockage, while the adjustment component 6 deflects to optimize the grinding effect. When the temperature returns to normal but the blockage is not completely cleared, the periodic collision between the pusher 103 and the conveying auger 403, along with the adjustment of the deflection direction of the adjusting component 6 and the inverted conical design of the movable housing 102, forms a spiral impact on both the upper and lower sides, which significantly enhances the anti-blocking and self-cleaning capabilities of the screening plate 502 and improves the overall processing efficiency.

[0100] This invention also provides a method for preparing soapberry rice flour using a grinding device with a cooling system, the preparation method comprising the following steps:

[0101] S1. Pre-treatment and preliminary crushing of saponin rice: First, the saponin rice is dried to ensure it reaches a dry state. The dried saponin rice is then fed into a crusher. The crusher performs preliminary crushing to prepare for subsequent grinding operations.

[0102] S2. Grinding of crushed soapberry rice: After the soapberry rice is crushed, the crushed soapberry rice is introduced into the installation cylinder assembly 1 through the feed inlet 7. Then, the grinding assembly 2 is started to perform fine grinding of the crushed soapberry rice in the installation cylinder assembly 1 to prepare the required powder product.

[0103] S3. Circulating grinding to improve efficiency and quality. During the grinding process, the circulation component 3 is started simultaneously. The circulation component 3 is responsible for extracting some of the saponin rice that has entered the grinding space and sending it back into the installation cylinder component 1. These saponin rice that are sent back will be processed again by the grinding component 2.

[0104] S4. Temperature monitoring and adjustment to prevent sticking: During the entire grinding operation, the temperature between the grinding assembly 2 and the fixed housing 101 is continuously monitored. Based on the temperature monitoring results, the working status of the mounting cylinder assembly 1 and the adjustment assembly 6 is adjusted in a timely manner to ensure that the grinding assembly 2 and the fixed housing 101 maintain a suitable temperature range.
