Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a grinding device with a cooling system and a method for making sapodilla rice flour. Background Art

[0002] Gleditsia sinensis, as the fruit of a deciduous tree of the genus Gleditsia of the Leguminosae family, has a wide range of application prospects in the fields of food, health care products and cosmetics due to its unique nutritional value and medicinal effects. In recent years, with the popularization of the concept of healthy eating, consumers' demand for natural, additive-free, and highly nutritious foods has continued to increase. Gleditsia sinensis, as a high-energy, low-protein, low-fat green food, is easier to store, carry and eat after being ground into powder, meeting the modern people's demand for convenient and healthy food.

[0003] The Chinese invention patent with application number CN201922102038.0 discloses a soapnut crusher for producing oryzanol, the soapnut crusher for producing oryzanol comprises a body and an upper cover, the top of the body is movably connected with the upper cover by a hinge, one end of the upper cover is movably connected with an electric telescopic rod by a pin, and the other end of the electric telescopic rod is connected to the side wall of the body by a pin. When the utility model is crushed, the pressing plate is pushed down by a connecting rod, so that the contact area between the soapnut and the crushing paddle can be increased, so that the crushing efficiency of the soapnut can be effectively improved, and the soapnut powder can be heated by a heater, so that the soapnut powder can be dried, wherein a glass cover is inlaid in the body cavity wall, the glass cover is a double-layer structure, and a vacuum layer is provided in the inner cavity of the glass cover, which can effectively reduce the loss of heat and improve the drying efficiency of the soapnut powder, and the vacuum layer cannot transmit sound, so that the noise can be reduced when the soapnut is crushed.

[0004] Although current technology can effectively improve the crushing efficiency of soap nuts by increasing the contact surface between soap nuts and the crushing paddle, there are still multiple challenges in processing soap nut rice powder grinding. This is mainly because soap nut rice has a high content of colloid, which easily generates high temperature during the crushing and grinding process, causing the colloid to stick together, making it difficult to achieve the ideal fine powder state.

[0005] In addition, in the grinding process, although the standard process includes setting up a screening device at the discharge port to filter the powder, due to the low mesh number of the screen, the screen of sapodilla rice flour is often blocked, which directly affects the smoothness and efficiency of the discharge. What is more serious is that after the equipment has been running for a long time, a large amount of insufficiently ground materials will gradually accumulate at the bottom of the grinding parts and the bottom of the container, which not only limits the normal operation of the grinding parts and reduces the grinding quality, but may also cause irreversible damage to the equipment structure.

[0006] At the same time, the problem of material adhesion to the grinding parts is also worthy of great attention. This adhesion not only further deteriorates the grinding effect, but may also cause the grinding parts to get stuck due to excessive load, thus seriously restricting production efficiency and equipment life.

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

[0058] The vacuum conveyor 302 is a device that uses a pneumatic pump to generate airflow, sucks materials through a pipeline system, and conveys them to a target location. Using the vacuum conveyor 302 to convey materials belongs to the prior art and will not be described in detail here.

[0059] An air delivery pipe 303 is disposed outside the vacuum conveyor 302 . A circulating air pump 304 is disposed at one end of the air delivery pipe 303 away from the vacuum conveyor 302 . The circulating air pump 304 is connected to the top of the fixed housing 101 .

[0061] The pushing part includes an electric push rod, and the connecting rod 601 can be controlled to deflect by controlling the upper and lower pushing parts of the connecting rod 601 to contract with different extension amounts.

A pressure sensor is provided at the connection between the spring and the rotating part 6051, and the pressure sensor is used to detect the elastic expansion and contraction amount of the elastic connecting member 6052. By detecting the specific value of the pressure sensor, it can be judged whether the material inside the mounting barrel assembly 1 has completed the grinding operation.

[0066] It should be noted that: during the process of grinding the soapberry rice by the grinding part 203, the first grinding surface 2031 is the main grinding surface, and the grinding operation of the corresponding mesh size is performed through the gap between it and the bottom of the movable shell 102 (the size of the gap can be controlled by the extension and contraction amount of the pushing member 103), and the second grinding surface 2032 is the secondary grinding surface, and the corresponding auxiliary grinding operation is performed through the extrusion between the adjustment component 6 and the inside of the movable shell 102.

[0074] A control terminal is disposed on the outside of the fixed housing 101 , and a control system is disposed inside the control terminal. The control system is used to control the movement of all electrical components on the 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 sapodilla rice into sapodilla rice powder mainly comprises the following steps:

[0077] First, the soapberry rice is thoroughly dried to ensure that it is completely dry, which is the basic condition for the smooth progress of the entire processing process. After drying, the soapberry rice is sent to the crusher and undergoes preliminary crushing treatment. This step aims to transform the soapberry rice into a raw material form suitable for further fine processing.

[0078] After the soapberry rice is crushed, the conveying device conveys the crushed soapberry rice to the inside of the feed port 7 , and the feed port 7 conveys the crushed soapberry rice to the inside of the fixed shell 101 .

[0079] After the soapberry rice enters the fixed shell 101, the control system starts the driving device 201, and the driving device 201 drives the grinding part 203 to rotate through the transmission shaft 202. During the rotation of the grinding part 203, the soapberry rice is gradually entered into the grinding space between the grinding part 203 and the movable shell 102 under the influence of centrifugal force, and the grinding part 203 grinds the soapberry rice entering the grinding space.

[0080] During the grinding operation, the first grinding surface 2031 and the second grinding surface 2032 on the grinding part 203 work together, and the first grinding surface 2031 and the second grinding surface 2032 finely grind the soapberry 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 soapberry rice that has entered the grinding space through the material pipe 301, and returns it to the interior of the fixed shell 101. Subsequently, the grinding part 203 performs a secondary grinding process to avoid putting too much soapberry rice into the grinding space at one time, which makes the grinding part 203 overloaded during operation, resulting in the problem of excessive temperature between the first grinding surface 2031 and the bottom of the movable shell 102, thereby ensuring the smooth progress of the grinding operation and the high-quality output of the product.

[0081] After completing the grinding process, the soapberry rice flour that meets the predetermined mesh size passes through the screening plate 502 installed at the bottom of the movable shell 102 and enters the internal space of the body 401. Then the conveying auger 403 built into the body 401 is started, and the conveying auger 403 conveys the soapberry rice flour along a predetermined path to the position of the discharge pipe 402 on the body 401. The soapberry rice flour is discharged from the discharge pipe 402 for further processing in the next process.

[0082] While the grinding operation is in progress, the control system will monitor two key parameters in real time: one is the value of the flow sensor on the screening plate 502, which is used to accurately grasp the amount of sapodilla rice flour passing through; the other is the value of the temperature sensor at the bottom of the movable shell 102, which is used to closely monitor the temperature changes in the grinding space. By comprehensively analyzing these two parameters, the control system can accurately determine the specific conditions in the grinding space between the bottom of the movable shell 102 and the grinding part 203. Based on this judgment, the control system regulates the installation barrel assembly 1 and the adjustment assembly 6 so that they can quickly adapt to the changes in the grinding space, thereby ensuring the stable and efficient grinding process.

[0083] When the control system monitors that the reading of the temperature sensor at the bottom of the movable shell 102 exceeds the preset threshold, while the value of the flow sensor on the screening plate 502 remains stable, it indicates that an excessive amount of soapberry rice has accumulated between the first grinding surface 2031 and the bottom of the movable shell 102, resulting in an excessive workload of the grinding section 203, which in turn causes the problem of excessive temperature between the first grinding surface 2031 and the bottom of the movable shell 102.

[0084] To deal with this situation, the control system immediately activates the adjustment component 6 in the movable slot to adjust the structure, and the two adjacent adjustment components 6 that were originally parallel to each other are changed into a staggered state (specifically, Fig. 9 This change effectively reduces the passage of the soapberry rice from the regulating components 6 to the first grinding surface 2031 and the bottom of the movable shell 102, forcing the soapberry rice to temporarily stay in the conical space formed by the two regulating components 6, reducing the flow of soapberry rice directly flowing into the grinding area, and alleviating the problem of excessive temperature of the grinding part 203 caused by excessive soapberry rice.

[0085] At the same time, the circulation component 3 remains in operation and continuously extracts the soapberry rice at the bottom of the movable shell 102. This dual measure further reduces the amount of soapberry rice flowing to the grinding surface, thereby more effectively controlling the temperature between the first grinding surface 2031 and the bottom of the movable shell 102 and preventing overheating.

[0086] The specific operation process of two adjacent adjustment components 6 that are originally parallel to each other to change into a mutually staggered state is as follows:

[0087] Assume that two adjacent adjustment components 6 are an A adjustment component and a B adjustment component.

[0088] First, the two pushing parts on the connecting rod 601 associated with the A adjustment component are controlled to extend synchronously. The two pushing parts are distributed symmetrically on the connecting rod 601. During the extension process, the pushing parts apply a torque to the right side to the connecting rod 601 through the hinge part 603, causing the connecting rod 601 to deflect in the clockwise direction. At the same time, in order to ensure smooth deflection, the telescopic part 602 on the connecting rod 601 is also extended synchronously to offset the obstruction that may be caused by the hinge part 603, thereby ensuring that the deflection process is not affected.

[0089] When the A adjustment component deflects, the two pushing parts on the connecting rod 601 corresponding to the B adjustment component are controlled to contract synchronously. This action causes the connecting rod 601 of the B adjustment component to be subjected to a force toward the left side, thereby deflecting in the counterclockwise direction.

[0090] Through the above steps, the A regulating component and the B regulating component are changed from being parallel to each other to being staggered. This structural change effectively adjusts the flow path of the material (such as sapodilla rice), reduces the amount of material directly flowing to the grinding area, and thus helps to control the temperature during the grinding process.

[0091] It should be noted that: during the transformation process of the adjustment component 6, when the connecting rod 601 deflects, the connecting ring 6053 distributed on the connecting rod 601 and the inner wall of the movable shell 102 are squeezed. This squeezing effect, under the buffering and guidance of the elastic connecting member 6052, causes the connecting ring 6053 to undergo a deflection displacement. This displacement is intended to ensure that during the deflection process of the connecting rod 601, the adapting portion 605 on the connecting rod 601 that may originally hinder its rotation can be smoothly avoided and no longer become an obstacle to rotation. Through such a design, not only the smoothness of the deflection of the connecting rod 601 is guaranteed, but also the flexibility and adaptability of the entire adjustment system are enhanced. This dynamic interaction between the connecting ring 6053 and the fixed shell 101, as well as the effective intervention of the elastic connecting member 6052, together constitute an efficient and stable adjustment mechanism, so that the A adjustment component and the B adjustment component can smoothly transform from a parallel state to a staggered state, thereby meeting various complex process requirements.

[0092] When the control system detects that the temperature sensor reading at the bottom of the movable shell 102 exceeds the preset safety threshold, and the flow sensor data on the screen plate 502 also exceeds the preset safety threshold, this combination indicates that abnormally high temperature has appeared between the first grinding surface 2031 and the bottom of the movable shell 102. This high temperature state is likely due to the gelatinous adhesion of the soapnut rice flour due to excessive heat, which in turn causes the screen plate 502 to be blocked.

[0093] When the control system detects that the screening plate 502 is blocked due to the gelatinous adhesion of the sapodilla rice flour, it immediately controls the pusher 103 and the adjustment component 6 to operate, and the pusher 103 causes the movable shell 102 to move downward, and the bottom of the movable shell 102 is separated from the contact with the grinding part 203, and the screening plate 502 is driven downward at the same time. In this process, the screening plate 502 compresses the telescopic conveying tube 501 until it is completely moved to the bottom of the connecting part 404. Since the spiral part of the conveying auger 403 is designed to be higher than the bottom of the connecting part 404 (specifically, as shown in FIG. 2 ), the spiral part of the conveying auger 403 is higher than the bottom of the connecting part 404 (specifically, as shown in FIG. 2 ). Figure 2 As shown in the figure, after the screening plate 502 reaches the bottom, the conveying auger 403 will intermittently knock on its lower surface, causing the screening plate 502 to vibrate, effectively removing the sapodilla rice flour blocked in the mesh. These rice flours are large in volume due to the colloid adhesion and are difficult to naturally pass through the mesh and fall into the conveying component 4. Therefore, after being knocked by the auger, they are also prompted to move along the periphery of the screening plate 502, and finally, under the suction of the material pipe 301, they are led to the top of the grinding part 203 for secondary grinding.

[0094] At the same time, when the material pipe 301 is extracting the sapodilla rice flour, 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 in the opposite state to the rotation direction of the grinding part 203 (specifically, Fig.10This is intended to allow the regulating component 6 to collide with the second grinding surface 2032 when the sapodilla rice powder passes through it, thereby slowing down its falling speed and providing an additional grinding effect to enhance the refinement effect of the sapodilla rice.

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

[0096] Assuming that the rotation direction of the grinding part 203 is clockwise, when the adjustment assembly 6 needs to be deflected, the two pushers on the connecting rod 601 associated with the adjustment assembly 6 are controlled to extend synchronously. The two pushers are centrally symmetrically distributed on the connecting rod 601. Therefore, during the extension process, they apply a torque to the right side to the connecting rod 601 through the hinge part 603, causing the connecting rod 601 to deflect in the clockwise direction. After the connecting rod 601 deflects clockwise, the top of the connecting rod 601 is in a state opposite to the rotation direction of the grinding part 203.

[0097] It should be noted that during the suction operation of the soapberry rice flour by the material pipe 301, since the first grinding surface 2031 of the grinding part 203 is separated from the bottom of the movable shell 102, this operation enables the material pipe 301 to not only extract the materials gathered around the screening plate 502 during operation, but also to suck the air between the grinding part 203 and the bottom of the movable shell 102 and the air in the body 401. This dual effect significantly accelerates the air circulation between the grinding part 203 and the bottom of the movable shell 102, thereby indirectly achieving a cooling effect on the bottom of the movable shell 102, which helps to maintain the working efficiency and stability of the equipment. When the material pipe 301 sucks the air in the body 401, the air in the body 401 enters the area between the grinding part 203 and the bottom of the movable shell 102 through the screening plate 502. After the gas enters the area between the grinding part 203 and the bottom of the movable shell 102, it impacts the bottom of the grinding part 203, so that the material adhering to the grinding part 203 can be cleaned.

[0098] When the temperature of the movable shell 102 is stably maintained within the normal range, the control system immediately directs the pusher 103 and the adjustment component 6 to return to their standard working state. If after this, the value monitored by the flow sensor configured on the screen plate 502 still exceeds the preset safety threshold, it indicates that the sapodilla rice powder adhering to the screen plate 502 has not been completely removed. At this time, the control system will immediately initiate countermeasures and drive the pusher 103 to perform telescopic movement, causing the bottom of the screen plate 502 to collide periodically with the spiral part of the conveying auger 403; at the same time, the control system adjusts the deflection direction of the adjustment component 6 to form a relative posture with the rotation direction of the grinding part 203 (specifically, Fig.11As the grinding part 203 continues to rotate, the soapberry rice is accelerated under the action of the deflection direction of the adjustment component 6 and moves down along the spiral path. Since the bottom of the movable shell 102 is designed as an inverted cone structure, the soapberry rice that moves down can effectively impact the top of the screening plate 502 in a spiral manner. This continuous impact on both the upper and lower surfaces greatly enhances the anti-blocking and self-cleaning functions of the screening plate 502, thereby improving the overall screening efficiency.

[0099] The present invention is provided with an adjustment component 6 and a pusher 103, and can monitor the temperature between the movable housing 102 and the grinding part 203, the flow rate on the screening plate 502 in real time by detecting the temperature sensor at the bottom of the movable housing 102 and the flow sensor on the screening plate 502, and optimize the material flow path and the grinding effect by changing the deflection direction of the adjustment component 6 and the telescopic state of the pusher 103, so as to ensure the stability and safety of the equipment operation. When excessive accumulation of sapodilla rice is detected, the passage of sapodilla rice to the grinding area is reduced by adjusting the parallel adjustment component 6 to a staggered state, the flow rate of sapodilla rice is reduced, and the temperature between the first grinding surface 2031 and the bottom of the movable housing 102 is cooled. When the screening plate 502 is detected to be blocked, the screening plate 502 is driven to vibrate and clear the blockage by the pusher 103, and the adjustment component 6 is deflected to optimize the grinding effect. When the temperature returns to normal but the blockage is not completely cleared, through the periodic collision between the pusher 103 and the conveying auger 403 and the adjustment of the deflection direction of the adjustment component 6, combined with the inverted cone design of the movable shell 102, a spiral impact on the upper and lower surfaces is formed, which significantly enhances the anti-blocking and self-cleaning capabilities of the screening plate 502 and improves the overall processing efficiency.
