A SKIN-REMOVING DEVICE FOR ROOT AND TUBER CROPS

摘要

A skin-removing device for root and tuber crops comprises a pedestal (1); a rotary drum (2) rotatably fitted on the pedestal and having an inlet (4) and an outlet (5), a helical screw feeder (3) provided in the rotary drum and fixedly connected with the inner wall of the rotary drum; and a driving unit for driving the rotary drum and the helical screw feeder to rotate together. During the use of the device, raw material of root and tuber crops is fed into the rotary drum via the inlet, and the driving unit drives the rotary drum and the helical screw feeder to rotate together. Under push action of the helical screw feeder, the raw material is continuously moved forward, and at the same time the raw material rotates along with the rotary drum and the helical screw feeder. During rotation, friction is generated not only among the raw material, but also between the raw material and the rotary drum wall and the helical screw feeder, so as to remove the skin of the raw material without damaging the flesh of root and tuber crops, such that the loss of raw material is low.
