How Does Beans Color Sorter Work?

At present, there are several types of color sorter machines in the industry, from beans color sorter machine, rice color sorter machine to plastic color sorter machine. However, no matter which type is it, the main idea of working color sorter is the same. The basic working principle is: the color difference between good item which is purity and defective item (unwanted). To get started the sorting solution, the color sorter 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. And we can adjust some degree electronic current is “safe” (good materials) and other is “dangerous” (defective or unwanted materials).

At last, when the electronic current is "safe", there is nothing happens and rice will successfully fall down to the accepted output; but if the electronic current is "dangerous", the ejector will be driven to blow away the bad or unwanted materials.
