The invention belongs to the technical field of sweet
potato processing, and especially relates to a sweet potato
skin cleaning device. The invention aims to solve the problem that surface walls of sweet potatoes are easily damaged by mechanical cleaning. The sweet potato
skin cleaning device comprises a cleaning box, wherein a water inlet
pipe and a blow-off
pipe are fixed to the bottom ends of the two sides of the cleaning box correspondingly; a water return
pipe is fixed to the top of the side, away from the water inlet pipe, of the cleaning box; fixed frames are fixed to the two ends of the top of the cleaning box correspondingly; and a feeding conveying belt and a discharging conveying belt are rotationally connected to two sides located between the two fixed frames correspondingly. According to the sweet potato
skin cleaning device in the invention,
silica gel blocks are used for increasing
friction force to guarantee conveying-out of sweet potatoes, so continuous movement and cleaning of the sweet potatoes are realized; the sweet potatoes are prevented from colliding with a stirring mechanism through friction of the
silica gel blocks and are thus prevented from surface walldamage, and the sweet potatoes slowly move along an inclined cleaning conveying belt and the feeding conveying belt so as to avoid collision with the inner wall of the cleaning box, so the completeness of the surface walls of the sweet potatoes is further improved after the sweet potatoes are mechanically inclined.
