Impurity screening device for food processing

The invention relates to the technical field of food processing, in particular to an impurity screening device for food processing. The device comprises a box body, the top of the box body communicates with a feeding pipe, a rotating roller is arranged at the upper portion of the interior of the box body, a material turning plate is fixedly installed on the surface of the rotating roller, and connecting shafts are connected to the two sides of the rotating roller in a bolted manner. A case body is bolted to the top of one side of the box body, and a connecting shaft at one side of the rotating roller is rotationally connected with the inner wall of the box body. The impurity screening device for food processing has the advantages of being capable of drying food processing raw materials, preventing the raw materials from adhering to impurities, enabling the raw materials to be effectively separated from the impurities in the screening process and improving the screening quality, and solves the problems that an
