[0030] Working principle:

[0031] During processing, soybeans are first added into the grinding box 3 through the soybean adding pipe 4. The first motor 9 is started, which drives the first rotating rod 10 at the output end to rotate. The first rotating rod 10 drives the grinding roller 11 at the lower end to rotate. The soybeans are continuously ground by the grinding particles 12 on the side wall of the grinding roller 11. After being ground into powder, the powder falls into the screening box 5. The second motor 15 is started, which drives the second rotating rod 14 at the lower end to rotate. The second rotating rod 14 drives the stirring plate 16 at the lower end to rotate, stirring the soybean powder. This causes the soybean powder to pass through the screen 7 and fall into the collection tank 21. When it is necessary to screen soybean powder of different particle sizes, the mounting plate 6 can be moved to move the screen 7 of other mesh sizes to the lower end of the screening box 5 and fix it by the limiting mechanism.
