In addition to the basic color selection function, some high-end grain color selection machines also have multiple functions such as stone removal, impurity removal, and grading, which can meet the needs of different users. Grain color sorter usually adopts a full-color touch screen operation interface with user-friendly design, making the operation more convenient and easy to learn.

The grain color sorter adopts a high-resolution CCD image sensor and a professional image processing system, which can accurately identify small color differences in grains. The color sorting accuracy can usually reach over 99.9%. Combined with high-frequency solenoid valves and other actuators, the grain color sorter can achieve high-speed and continuous sorting operations, with a large processing capacity and high efficiency.
