Screening device for wheat germ powder deep processing

The invention discloses a screening device for wheat germ powder deep processing. The bottom of a first screening barrel is fixedly communicated with a first discharging barrel, the bottom of the first discharging barrel is fixedly communicated with a discharging pipe, and one side of the first screening barrel is fixedly communicated with one side of a secondary screening device. By arranging a spiral blade, materials can be driven to enter a first screen, rotating crushing cutters can crush the caked materials, the screening effect can be better, the screened materials can fall down and be collected along with the first discharging barrel, the materials with the large size can be discharged into the second screening barrel, due to stirring of a fixing plate, secondary screening is conducted, it is guaranteed that small-particle materials on the surfaces of the large materials are screened and recycled, and the situation of material waste is prevented to a certain extent. A blocking device is arranged, so th
