It is a type of agricultural product processing industry in a broad sense, and raw material crushing equipment is needed to pre-treat the raw materials in the food processing process.

[0003] The existing food raw material crushing and processing pretreatment structure crushes the raw materials by driving the two sets of crushing rollers to rotate in opposite directions during use, and at the same time, a screen plate is required to screen the crushed raw materials. During the screening process, since the screening is carried out by gravity, it is easy to cause raw materials to accumulate, affecting the screening efficiency and the collection efficiency of the raw materials, resulting in poor use of the device. Therefore, a food raw material crushing and processing pretreatment structure is urgently needed to solve the above problems. Utility Model Content
