| 释义 |
}} FeaturesA rice color sorting machine, also named rice colour sorter, separates rice grains according to color differences in raw rice arising from anomalies like bits of stone, bad rice, black rice, half-husked rice, etc. A high-resolution CCD optical sensor drives a mechanical sorter to separate different granular materials, automatically sorting heterochromatic particles out of the batch of raw rice; removing such impurities in this process improves the quality of the rice. Working principleRice processing begins in a milling plant, where the harvested grains run through a production line where the rice is boiled, dried, de-stoned, husked, hulled and shelled. It then is taken to the color sorter machine. At this point, the rice mixture will travel by elevator belt into a hopper on top of the machine, from which it will flow down along chutes in the colour sorter, streamlining their flow to so that they may be scanned by CCD sensors. The moment the camera detects any color defects, the camera instructs ejectors fitted in the machine to open the nozzle. The nozzle is connected to valves containing compressed air. This air is then used to shoot out the color defected material from the input rice. The types of defects in rice include black tipped, chalky, yellow, mouse droppings, immature grain, etc. Working Environment
