Rice processing begins in a milling plant, where the paddy is cleaned, hulled, husked, de-stoned, graded and whitened. It then is taken to the color sorter machine to separate heterochromatic granular materials.

Color sorters can deliver premium quality and appearance on all varieties of rice. SKY RM Series RGB Color sorter can easily be switched between modes, programmed to sort different variants of rice such as basmati rice, brwon rice, red rice, black rice, jasmine rice, white rice , parboiled rice at an accuracy of 99.99%.
