A Rice Polishing Wheel is a crucial component in modern rice milling, responsible for giving rice grains their final smooth, shiny, and uniform appearance. Beyond aesthetics, effective polishing improves rice quality, removes residual bran layers, and enhances consumer acceptance. High-quality rice polishing wheels play a vital role in delivering premium-grade rice with minimal grain loss.
What Is a Rice Polishing Wheel?
A rice polishing wheel is an abrasive wheel installed in rice polishing or whitening machines. It gently removes remaining bran and fine impurities from rice grains after husking and whitening. By applying controlled friction, the polishing wheel enhances surface smoothness without damaging the rice kernel.
These wheels are widely used in both raw and parboiled rice processing, including premium varieties such as basmati rice.
