Quartz sand color machine market has been promising in recent years, there is no lack of producers have a huge profit margins, and the entire color selection machine market is growing. Color sorter is the heart of the core recognition system # recognition system is the sensor. Color selector sensor is mainly divided into traditional sensor type (photoelectric tube, silicon photo cell, etc.) and CCD (or MOS) sensor based on the two kinds of. The use of CNC, wave type measuring instrument, voltage meter, current meter, temperature measurement table is easy to use. Newly developed software greatly enhance the color selection effect. Slide and tube are installed in the heating plate, can adjust the most suitable working temperature. Using high performance integrated block, can greatly reduce the failure rate, saving power consumption. China color sorter industry market scale is expanding constantly, at the same time, from the rice color sorting to beans, peanuts and other crops to choose color, tea color selection, color sorting machine application in agricultural products processing in the field of expanding, covering almost all agricultural products.
