After the material enters the color sorter, it is first evenly distributed on the vibrating conveyor belt, and then the material moves under the photoelectric sensor through the conveyor belt. Sensors detect the color, shape, size, and other characteristics of materials through photoelectric effect, and compare them with preset sorting standards. When defective products or impurities are detected in the material, the control system will immediately activate the removal device to separate the defective products or impurities from the material. Finally, high-quality and defective products are transported to different discharge ports to complete the sorting process.

The food color sorter uses high-precision sensors and image processing technology to perform spectral analysis and image recognition on food. When food materials pass through the detection area of the color sorter, sensors will capture information such as the color, shape, size, etc. of the food and compare it with preset standards. If food that does not meet the standards (such as discolored particles, impurities, defective products, etc.) is detected, the color sorter will immediately activate the removal device to remove these unqualified foods from the production line.
