Grain color sorter

The device is composed of a lot of small photoelectric sensor array, it uses high quality camera special high-definition camera, the flow of each channel within the scope of the material, there are usually several to dozens of sensors to separate detection (can be regarded as compound eye structure, and a single piece of silicon solar cell it is unilateral structure). Early grain color sorter using photoelectric tube, photoelectric diode, silicon photocell to detect optical signal, its biggest advantage is low cost, easy fabrication, debugging and production, the signal processing circuit is simple, the corresponding optical system using a simple electric eye, which is composed of two pieces of simple lenses. Do not need to be adjusted, the cost is relatively low. Using U type slide, improve the precision of color separation, and can reduce the band ratio. Slide with the heating plate, to avoid sticking rice bran in the chute, affecting the normal material flow. Humanized true color touch screen, visual effect is clear, easy to operate.
