Rice color sorter
Rice color sorting machines are used in rice mill plant during the processing of rice. It is the last stage before the packing of processed rice. First of all, the rice is milled in the mill plant, taken through the paddy boiling unit, drier, destoner, husker, and whitener and then the produced final rice is taken to the color sorter machine. In color sorting stage, the rice is scanned using a machine that has a line scan camera. The moment the camera detects any color defects, the camera instructs the 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 are: black tipped, chalky, yellow, mouse droppings, immature grain, etc. the basic working principle is: the color difference between good rice and bad or unwanted rice. First of all, the machine should translate the photo signal to electronic signal by photo-sensor and other complex element; then due to there is difference between good materials and bad materials, so corresponding there is also a difference good materials' electronic current. Camera Sorter is a highly functional machine and is used for a variety of color sorting applications. The product to be sorted can be scanned at high speed that produces a very high resolution image of the object by using advanced high resolution line scan cameras.
