1. 2048 pixels high-sensitivity CCD sensor with professional processing algorithms, very good image quality with extremely low noise, thus the defects can be easily identified. It's  especially suitable for eliminating mildewed and spotted wheat, mouse droppings, seeds, small stones and other impurities.
2. the LED lamps with special wavelength have very long life(more than three years). It uses patented technology to reduce working noise. the LED lamps have good stability and are cost-effective.
3. New generation high-speed single ejector, frequency up to 1100hz above, fast switching speed, precise control without air tail, high hitting accuracy, low bring out, less air consumption, large production, and long life(more than 1 billion times, insurable with three year).
4. Large chute with special treatment on the surface, smooth wear, so wheat is not easy to jump to ensure the stability of the color sorting effect, the smooth chute can also reduce the carry out.
5. A well-designed Human interface, intelligent, powerful, clearly structured with 3 grade password. the "one -key intelligent adjustment" function is very user-friendly, simple and easy to use.
6. the machine has greatly enhancing system reliability. It uses many international brand-name parts, designed with optimized circuits, manufactured with advanced arts and crafts, it has intelligent on-board monitoring system such as temperature, voltage, current, ejector working state, etc.
