Rice processing refers to grinding and crushing rice to facilitate in-depth processing.

[0003] Patent No. CN212632852U is a kind of rapid crushing and grinding equipment for rice processing. Through the crushing knife, the rice can be primary cut, which effectively improves the subsequent rolling effect of the rice. Through the coordinated use of the rolling roller and the grinding block, the rice is subjected to secondary filtration and secondary rolling, so that the grinding quality is high and the grinding effect of the rice is greatly improved.
