The main varieties of potato products are potato chips, potato chips, potato mud dehydration. Regardless of the type of products, the processing of raw materials are required to potato peel treatment, in order to ensure the quality of products, ensure the appearance, color and taste. Method for peeling potatoes are peeled, peeled, artificial mechanical chemical peeling, peeling and steam peeling, radiation. Better artificial skin peeling effect, but low efficiency, high loss rate, obviously can not meet the needs of the development of potato industry. Peeling machine with centrifugal peeling and abrasive peel two form, friction between the main dependence between potato and potato and potato and emery or rubber to achieve the purpose of skin. This method of peeling effect is poor, and easily causes the potato surface layer damage. Chemical peeling with hot alkali method and low temperature of peeling liquid method in two forms, mainly rely on the alkali solution and special chemical peeling liquid, softening and relaxation of potato skin and eye, then use high-pressure water jet, achieve peeling purpose. This method of peeling and washing high process requirements, and lye or peeling liquid consumption is too large, high cost. Radiation is the radiation wave is peeled potato skin moisture absorption, evaporation, radiation pokong incident into the heating body surface that is caused by a strong resonance, absorbed and converted into heat, so as to achieve better effect with the method of peeling peeling effect, but the skin can waste, can not be used. Steam peeling is the potato for a short time in the steam treatment, the cortical maturation, and then use the iron brush and water rushed to skin, skin to achieve.
