The study developed an automatically cleaning impurity and sorting device of tomato sauce production line. The device is constitutes with the bracket, sprocket wheel, sprocket roller sieve, discharging tray, gear motor, photoelectric sensor and automatic control system. By the experimental analysis, the average sorting fruits selection rate of the device is as high as 97%, average lump impurity removal rate was 78%, average strip impurity removal rate was 99%, Suitable for continuous treatment of a large number of raw materials containing impurities, to meet the actual needs of production.
