Motor 2 58 provides power to drive shaft 55 to rotate, causing hammer blades 56 to swing around shaft 55 to crush the soybeans. Filter screen 53 filters the crushed soybeans. Then, turn on motor 1 22. Motor 1 22 provides power to drive impeller 23 to rotate and quickly discharge the soybean milk. Reducer 2 24 causes moving grinding block 31 to rotate at a slower speed than impeller 23. The rotation of moving grinding block 31, in conjunction with stationary grinding block 32, grinds the soybeans. Simultaneously, cooling water is introduced into the moving grinding block 31 and the stationary grinding block 32 through cooling channel 1 41 and cooling channel 2 42 to cool the moving grinding block 31 and the stationary grinding block 32, preventing the soy milk from producing a burnt taste due to high temperature during grinding.

[0035] like Figures 1 to 7 As shown, this utility model discloses a grinding device for processing glucono-delta-lactone tofu. During operation, soybeans and water are first poured into hopper 2 54. Then, motor 2 58 is turned on, providing power to drive the rotating shaft 55 to rotate, causing the hammers 56 to swing around the shaft 55 to crush the soybeans. A filter screen 53 filters the crushed soybeans. Afterwards, motor 1 22 is turned on, providing power to drive the impeller 23 to rotate and quickly discharge the soy milk. Reducer 24 causes the moving grinding block 31 to rotate at a slower speed than the impeller 23. The rotation of the moving grinding block 31... The stationary grinding block 32 grinds the soybeans, while cooling water is introduced into the moving grinding block 31 and stationary grinding block 32 through cooling channel 1 41 and cooling channel 2 42 to cool them down and prevent the soybean milk from developing a burnt taste due to high temperature during grinding. The water tap 62 is kept closed during grinding. At this time, the soybean milk is driven by the impeller 23 into the pipe 2 63 and flows back to the hopper 2 54, re-entering the machine for repeated grinding. This prevents the soybean milk from being discharged from the machine before the soybeans are fully ground, and facilitates the control of the soybean milk concentration.
[0036] The motor 22, filter 53, motor 58, and faucet 62 of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

Furthermore, by setting up a crushing device 05, the soybeans are crushed by hammering, improving crushing efficiency and increasing the machine's production efficiency. This solves the existing technical problems that require the continuous addition of water to the machine during grinding, making it inconvenient to control the concentration of the soybean milk, resulting in poor machine ease of use, and that existing machines crush whole materials by grinding, resulting in low crushing efficiency and low machine production efficiency.
[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
