Based on the litchi fruit's physical and chemical properties, a new continuous fruit peeling equipment had been designed to combine the grade and peel unit. The device integrates photoelectric beam machine into the grading unit, which makes litchi fruit peeling easily after rating. The peeling mechanism is that the graded fruit cut a small opening firstly, then torn the peel. Thus the equipment could continuously finish fruit rating, orderly loading, cutting, peeling and fruit collection. Therefore, it could achieve not only achieve the high efficient rating and peeling operation, but also keep the litchi fruit integrity, which is beneficial to automation of litchi fruit rating and peeling, and the industrialization production.
