Color sorter is a kind of intelligent detection and sorting equipment. It takes the color difference of detected materials as the basis for sorting and elimination, and uses photoelectric detection to automatically sort out the different colored particles in granular materials. The color sorter integrates light, machinery, electricity, gas and magnetism. It is mainly composed of four parts: feeding system, photoelectric system, electric control system and sorting system.
The color sorter is a photoelectric integrated equipment for selecting different color particles from the selected materials, which is composed of feeding mechanism, chute (belt type), sensor, spray valve and computer control system based on the difference of optical characteristics of the selected materials and the photoelectric principle. When the size and density of unqualified particles and qualified particles are very close, color sorting can be said to be an optional non manual sorting method.
Color selection can eliminate the moldy, yellowing and impurities harmful to people in agricultural products with similar particle size. With the continuous pursuit of a better life and the increase of food safety awareness, people also put forward high requirements for strengthening the cleaning of malignant impurities and pesticide residues in edible agricultural products, which puts forward unprecedented high requirements for the production, processing and management of agricultural products. It has become the common goal of businesses to further increase the edible safety of agricultural products and increase the appearance and quality of products after classification. Therefore, color separation is widely used in the field of edible agricultural products sorting, and has become an important process in the finishing process of agricultural products.
