A grain color sorter is a machine used in the agricultural and food processing industries to sort grains, seeds, and other agricultural products based on their color. The process of how a grain color sorter works can be broken down into the following steps:
Feeding and Dispensing: Grains are fed into a hopper or a conveyor system, where they are uniformly distributed for sorting. This can be a vibrating chute or a conveyor belt.
Illumination: As the grains pass through the sorting system, they move along a conveyor belt beneath a strong source of illumination, usually white light. The uniform lighting helps ensure that the color of each grain is clearly visible.
Image Acquisition: A high-speed camera or multiple cameras capture images of the grains as they move past the illumination source. These cameras are equipped with sensors that are sensitive to different colors.
Image Processing: The images captured by the cameras are then processed by a computer or an embedded system. Advanced image processing software identifies the color of each grain in the image.
Sorting Decision: Based on the color information obtained from the image processing, the system makes a quick decision about the category or quality of each grain. It decides whether the grain should be accepted and remain in the sorting stream or rejected.
Air Ejection: Grains that do not meet the desired color criteria are separated from the accepted grains. This is typically done using a system of air nozzles. The air nozzles are positioned along the conveyor belt, and when a grain that needs to be rejected passes under the nozzle, a burst of air is released. This burst of air propels the unwanted grain into a separate channel or container for rejected material.
Accepted Material Collection: Grains that meet the desired color criteria continue on the conveyor belt and are collected in a separate container, ready for further processing or packaging.
Continuous Operation: The entire process occurs in real-time as grains move along the conveyor belt. The speed and efficiency of the sorting process are high, allowing for the rapid sorting of large quantities of grains.
It’s important to note that modern grain color sorters（产品链接：https://www.techik-colorsorter.com/grain-color-sorter-wheat-colour-sorting-machine-product/） can be highly sophisticated and are often equipped with advanced image processing algorithms, multiple cameras, and customizable sorting criteria. This allows them to sort not only based on color but also on other characteristics such as size, shape, and defects, making them versatile tools in the agricultural and food processing industries.
