Description

Technical Field

[0001] This utility model relates to the field of soybean processing technology, specifically to a soybean crushing and grinding equipment. Background Technology

[0002] Soybean crushing and grinding is a core pre-processing step in the production of soy products (tofu, soy milk, soy protein, etc.). By crushing and breaking down the cell walls of soybeans and grinding them into fine particles, the protein, oil and other nutrients in soybeans are fully released. It is widely used in food processing plants, soy product workshops, feed production and other scenarios.

[0003] Traditional equipment often adopts a split design of "separate crusher + independent fine grinding mill". Soybeans need to be crushed and then transferred to the fine grinding equipment. The process is cumbersome and dust is easily wasted during the transfer. At the same time, the high-speed friction of the grinding wheel during the fine grinding process generates a lot of heat, which raises the temperature of the raw materials. When the temperature of the raw materials rises above 60°C, it will cause the soybean protein to denature and the vitamins to be destroyed, reducing the nutritional value of the finished product. In view of this, a soybean crushing and fine grinding equipment is proposed. Utility Model Content

A first fixed blade 101 and a second fixed blade 102 are fixedly installed on the inner wall of the shell 1. Both the first fixed blade 101 and the second fixed blade 102 are bolted to a grinding disc 103. Two sets of grinding discs 103 are provided, symmetrically arranged about the center line of the first fixed blade 101. A filter screen 104 is provided in the crushing and grinding chamber of the shell 1.

[0021] In this embodiment of the invention, the rotating assembly 4 includes a rotating shaft 41, which is fixedly connected to the crushing blade 5. A transmission wheel 42 is fixedly connected to the end of the rotating shaft 41 away from the crushing blade 5. The transmission wheel 42 is connected to a transmission wheel 43 via a transmission belt. The transmission wheel 43 is fixedly connected to the output shaft of the motor 44. The discharge port 3 is fixed to the crushing and grinding chamber of the housing 1. The crushed and ground soybean powder enters the discharge port 3 through the filter screen 104 and is discharged. The output shaft of the motor 44 drives the transmission wheel 43 to rotate. Under the transmission of the transmission belt, the transmission wheel 42 drives the rotating shaft 41 to rotate. The crushing blade 5 can crush the soybeans in the crushing and grinding chamber of the housing 1. During this process, the crushing blade 5, the fixed blade 101, and the fixed blade 202 work together to crush the soybeans. Combined with the grinding disc 103, the grinding is completed directly within the chamber, eliminating the need for additional transfer steps and completely solving the problem of cumbersome processes in traditional split-type equipment. The integrated design avoids dust waste during transfer and improves raw material utilization.

[0022] Furthermore, the blower 6 is connected to the crushing and grinding chamber of the housing 1 through a connecting channel. A filter screen 104 is also installed at the crushing and grinding point of the housing 1 through the connecting channel. The use of the blower 6 can introduce cold air from the outside into the crushing and grinding chamber of the housing 1, remove the heat generated during the crushing process, effectively prevent the denaturation of soybean protein and the destruction of vitamins, and retain the nutrients in the raw materials to the maximum extent. At the same time, it can continuously blow the filter screen 104, effectively preventing the crushed and ground soybean raw materials from clogging the filter screen 104 when discharged, reducing the number of times the filter screen 104 needs to be disassembled and cleaned, and ensuring the continuous operation of the device.

[0023] Furthermore, the auxiliary feeding mechanism 7 includes a connecting shaft 71, one end of which is fixedly connected to a transmission wheel 72, and the other end of which is fixedly connected to a cam 74. The connecting shaft 71 passes through a limiting sleeve 73 and is rotatably connected to the limiting sleeve 73. A guide rod 76 is fixedly connected to the bottom inner wall of the housing 1.

[0025] In use, soybeans are first added into the crushing and grinding chamber of the housing 1 through the feed inlet 2. Then, the motor 44 is started, and the output shaft of the motor 44 drives the transmission wheel 43 to rotate. Under the transmission of the transmission belt, the transmission wheel 42 drives the rotating shaft 41 to rotate. The crushing blade 5 can crush the soybeans in the crushing and grinding chamber of the housing 1. During this process, the crushing blade 5, the fixed blade 101, and the fixed blade 2 102 work together to crush the soybeans. Then, the grinding disc 103 directly completes the fine grinding in the chamber. At the same time, the fan 6 is started to input cold air from the outside into the housing 1. In the crushing and grinding chamber, the heat generated during the crushing process is carried away, and the filter screen 104 is continuously blown, which effectively prevents the crushed and ground soybean raw material from clogging the filter screen 104 when it is discharged. During the rotation of the rotating shaft 41, under the transmission action of the first transmission wheel 42, the transmission belt and the third transmission wheel 43, the connecting shaft 71 can drive the cam 74 to rotate counterclockwise. Under the action of the guide rod 76, the moving plate 75 drives the elastic block 77 to move up and down reciprocally under the action of the return spring, which vibrates the discharge port 3 and speeds up the discharge of the discharge port 3.
