Grinding machine for rice powder processing

Abstract

A grinding machine for rice flour processing, this utility model relates to the technical field of food processing equipment. A material feed rack is fixed to the bottom of the feeding ring; the bottom of the material feed rack has a downward-facing groove; several discharge holes are opened at the bottom of the material feed rack; a first filter screen is fixed to the bottom of the material feed rack; the first filter screen is screwed onto the rotating shaft via a bearing; a second filter screen is fixed to the bottom of the connecting ring, the mesh size of the second filter screen being smaller than that of the first filter screen; a second grinding frame is placed on the second filter screen and is fixed to the rotating shaft, both the upper and lower parts of the second grinding frame having a conical structure; vibration mechanisms are respectively located on the left and right side walls of the collection box; a double-layer graded grinding structure is adopted, effectively reducing the burden on the grinding device and improving grinding uniformity by first coarse grinding and then fine grinding; the raw materials are evenly dispersed and fall, avoiding feed accumulation; the spring vibration mechanism prevents raw materials or particles from clogging the mesh, improving grinding efficiency.
