Abstract. Poria cocos is the dry sclerotia of Poria cocos (schw.) wolf, a porous fungus. Long-term treatment of Poria cocos can "remove all diseases, moisten skin and prolong life". Poria cocos skin, the dry outer skin of Poria cocos sclerotia, is irregular sheet, slightly elastic, brown or dark to dark brown, with tumor like protuberances. In order to solve the problems of irregular and uneven shape of Poria cocos, as well as the difficulty of manual peeling, heavy loss and unclean removal, a small practical horizontal Poria cocos peeling machine with machine vision technology was designed. The machine is mainly composed of peeling device, image acquisition device, PLC electric control device, conveying device, positioning clamping device and material collection device. Using machine vision and PLC control technology, Lingnong only needs to operate the control panel to achieve the automatic peeling requirements of Poria cocos and achieve good human-computer interaction. Compared with manual peeling, the effect is significantly higher than manual peeling. The designed intelligent horizontal Poria cocos peeling machine has good peeling effect, and the design scheme is feasible.
