The FstSort potato grader consists of an elevator and a sorter. The material is first poured into the roller elevator, which is evenly distributed through the roller elevator to the sorting machine moving forward in parallel and gradually increasing the gap between the rollers, through the machine sorting, the "size" of the larger potatoes and the "size" of the smaller potatoes are separated, and then bagged separately. The potatoes that were originally of different sizes are then transformed into fine potatoes. The sorting speed can be adjusted ,4-6 grades. The output is 5-8 tonnes per hour, saving labour.
