Through the analysis of original data, project demonstration and related data analysis and calculation, the overall design of a complete potato peeler to peel and mechanical structure is a new form, to better serve the fruits and vegetables to the development of leather industry, better adapt to the demand of the market both at home and abroad, so has the good market prospect.Keywords: potatoes peeled structure； Friction； drive1 the domestic research statusTechnology is to measure whether an enterprise has the advanced nature, whether have market competitiveness, whether can keep ahead of competitors important index. With the rapid development of domestic potato peeling agency market, the core of the related production technology and research and development will certainly has become the focus of the industry enterprises. Understand the potato peeling machine in the production of the core technology research and development at home and abroad, process equipment, technology, application and trend, for an enterprise to improve product technical specification, improve the market competitiveness is critical.Potato products the main varieties of potatoes, potato chips, dehydrated mashed potatoes, etc. No matter what kind of products, its processing technology requirements of raw materials to deal with the peel potatoes, to guarantee the quality of the products, ensure its appearance, color and taste. Peel potatoes peeled methods mainly include artificial, chemical peeling, mechanical peeling, etc. Artificial to skin peeling effect is better, but low efficiency, high loss rate, obviously can not adapt to the needs of the development of the potato industrialization; Chemical peeling a hot alkaline or peel and low temperature liquid method in two forms, mainly rely on the strong alkali solution and liquid chemical peeling effect, softening and relaxation potato skins and body-to keep, then use high pressure water jet, peeled. This method the flushing process of before and after peeling the demand is higher, and liquid alkali, peel or consumption is too large, the cost is higher, and this way the serious influence the taste of the product. Mechanical peeling is friction peel form, the main dependence between potato and potato and potato with silicon carbide or rubber friction between role and achieve the goal of peel, good effect of this approach to skin, reduce the production cost, reduced environmental pollution, simple operation, fast speed, can one person operation, high energy efficiency to maximize the interests of the products.2. the working principle of the potato peeler The potato peeling machine adopts horizontal machine, mainly including working cylinder, work table, frame and transmission parts (see diagram). When to work in the potato peeling machine, wheel rotation, the material by a bucket shape inlet, material fall on the surface of a rotating brush roller corrugated bulge, the effect of the centrifugal force by the brush roller tangent upward movement, material constant along the motion for a cylindrical wall, rise to the top, was at the top of the block back into the working surface of the plate. Into the rough surface and friction brush roll. The reciprocating movement of the material in this process, by violent agitation, and formed with a brush roller, wall and between particles is given priority to with flip, rubbing friction, impact of comprehensive mechanical effects, so as to achieve the aim of the skin. At the same time of friction peel, from inject water into the hole, in a timely manner will be wiped off the skin of the through brush brush roll and roll gap to discharge mouth eduction body. In the case of non-stop, open the discharge valve of mouth, material by dial discharged through the discharge port. After peeling potatoes peel by institutions discharging chute into the auxiliary body, after screening and other auxiliary work again into the next procedure.3. summary Believe in the near future, once the product is applied to the actual, will greatly save the working time, improve work efficiency, improve the economic benefit, at the same time will make a great contribution for the mass production, giving impetus to the development of potato industry better and faster. Mechanical peeling, powered by motor, through the pulley drive cylinder at the bottom of the spinning mill. Low middle, high edge mill wheel surface, undulate. Tubers to join the cylinder, each other due to centrifugal force and the friction e
