Rice cleaning machine is essential pre-processing equipment in rice milling production line, widely used for paddy, brown rice and finished white rice purification.

This machine combines vibration sieve, air winnowing and gravity separation in one unit. It can efficiently separate heavy impurities like stones, clods, and light impurities including husks, grass, dust, shriveled grains, as well as broken rice. After cleaning, rice purity will be greatly improved, reducing wear on the subsequent rice polisher and milling machine, and upgrading final rice grade.

We supply multiple models covering capacity from 0.5t/h to 25t/h. Small mobile type is suitable for grain purchasing stations and small rice factories; medium & large fixed models serve for large-scale rice processing plants and grain warehouses.

Key Advantages
