The invention relates to a poria cocos peeling auxiliary processing device. The device comprises a bottom plate, placing plates, fixing clips and a peeling device; the placing plates are installed onboth of the left side and the right side of the upper end of the bottom plate; the fixing clips are rotatably installed on the central part of the placing plate by bearings; an arc-shaped groove is arranged in the central part of the bottom plate; the inner part of the arc-shaped groove is connected with the peeling device in a sliding fit mode; each fixing clip comprises a fixing bolt; and the fixing bolts are installed in the central parts of the placing plates by bearings. The peeling auxiliary processing device solves the problems that during poria cocos peeling, the efficiency of manual peeling is low, a peeling machine fails to peel the edge of a fixed end, the peeling effect is poor due to poor fixation, the peeling thickness is not adjustable, poria cocos bulges cannot be treated,a blade is easily damaged, the resources are wasted, and the like in the prior art. The device has the function of peeling poria cocos and has the advantages that the peeling efficiency is high, peeling can be finished at one time, the thickness of the blade is adjustable, the poria cocos bulges can be treated, the blade is protected, the resources are saved and the peeling effect is good.
