1. Sand roller rice mill: It mainly relies on the sharp edges of the diamond sand on the surface of the high-speed rotating sand roller to grind off the skin of the rice grains.
2. Iron roller rice mill: It uses the ribs or bumps on the surface of the iron roller to rub and squeeze the rice grains to achieve rice milling.
3. Air jet rice mill: During the rice milling process, air is sprayed into the whitening chamber to help reduce the temperature of the rice grains, reduce broken rice and increase the rice output rate.
These different types of rice mills differ in structure, working principle and applicable scenarios to meet different processing needs.
