Rice Sorting


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%.

How does it work?


Milled rice mixture are put into a hopper on top of the machine, from which it flows down along chutes in the color sorter, be scanned by CCD sensors. When the camera detects any color or size defects, it instructs ejectors fitted in the machine to open the nozzle, where compressed air is used to shoot out the defected material from the input rice.
