Fruit and vegetable sorting refers to the process of classifying and sorting fruits and vegetables according to their weight, size, shape, color, texture, defects and other characteristics. The sorting equipment can send fruits and vegetables to the sorting area through a conveyor belt. The sensor detects various characteristics of fruits and vegetables, such as size, shape, color, weight, etc., and converts these characteristics into electrical signals and sends them to the control system. The control system determines the quality and grade of fruits and vegetables according to preset standards and algorithms, and takes corresponding measures to classify them into different grades
