摘    要
馬鈴薯為植物的塊莖，形狀為圓形或橢圓形，其結(jié)構(gòu)由表皮層、形成層、外果肉和內(nèi)果肉四部分。馬鈴薯品種可分兩大類，一類是淀粉含量較高的，適宜于作為生產(chǎn)淀粉的原料，另一類是蛋白質(zhì)含量較高，適宜作為蔬果或制成多種食品[1]。
馬鈴薯營養(yǎng)豐富，除直接食用外，還可以加工成食品、全粉、淀粉等經(jīng)濟(jì)價值較高的食品，通過加工可以大幅度提高鮮薯的商品價值[2]。
鑒于馬鈴薯的很多特點(diǎn)，馬鈴薯得到了廣泛的利用。a.馬鈴薯可鮮食，鮮食用馬鈴薯主要用作家庭餐館烹調(diào)，我國主要用來制作菜肴、面點(diǎn)小吃等大眾食品。果外除蒸烤鮮馬鈴薯作主食外，還有咖哩飯、燉薯快以及色拉涼拌菜。馬鈴薯可制成方便食品、快餐食品、休閑食品，如馬鈴薯粉、馬鈴薯全粉、脫水馬鈴薯片（條）、速凍薯條（薯泥）、蒸薯條、罐裝和去皮馬鈴薯、馬鈴薯脆片、馬鈴薯膨化小食品等；b，加工成淀粉及相關(guān)產(chǎn)品：由于馬鈴薯淀粉的優(yōu)良特性，不僅是制作高級方便面、面類最為理想的添加淀粉，而且還是肉制品、魚糜制品等的添加劑或原料。馬鈴薯淀粉也是粉條的優(yōu)質(zhì)原料。出馬鈴薯淀粉外，也可得到相關(guān)產(chǎn)品，包括各種變性淀粉、飴糖、葡萄糖、膳食纖維制品等。C,其他制品：馬鈴薯提取淀粉后的殘渣可制成馬鈴薯發(fā)酵飼料、提取蛋白等[5]。
去皮（peeling）用于多種水果和蔬菜的加工中以除去不需要或不可食的物質(zhì)，并改善成品的外觀。主要的考慮因素包括通過盡可能減少去掉的部分以及可能降低能源、勞力和物質(zhì)成本來降低總成本。這里，介紹摩擦去皮方法：食品被放置在金剛砂滾軸上或內(nèi)壁排列著金剛砂的轉(zhuǎn)筒中，在磨損力的表面除去食品的表皮后又被大量的水沖洗干凈。該方法的優(yōu)點(diǎn)是由于過程是在溫室下進(jìn)行而具有的能源成本低以及資本成本低、無熱損傷，食品外觀良好的優(yōu)點(diǎn)，不規(guī)則食品表面（如馬鈴薯上的“孔眼”）會破壞去皮產(chǎn)品的外觀，需要手工去除[3]。

 Abstract
  Potato tuber for plants for circular or elliptic shape, structure, by cuticular layer and layer, the pulp and pulp within four parts. Potato varieties can be divided into two kinds, one kind is starch content high, suitable for the production of raw materials as starch content of protein, another kind is higher, suitable for various fruits or food..
Potato nutrition is rich, besides direct edible, but also can be processed into food, powder, starch, etc, the economic value of higher food processing can be greatly improved through the value of fresh chips.
In view of many of the characteristics of the potato, potato has been widely used. a. can be fresh potatoes, fresh potatoes used mainly for cooking the family restaurant, China is mainly used to create dishes such as pasta snack food of the public.In addition to fresh fruit outside the potato for food, there are curry rice, stew and potato salad cold fast food. Potatoes can be made from convenience foods, fast foods, snack foods, such as potato flour, potato powder, dehydrated potato chips (article), frozen French fries (potato mud), steamed potato chips, canned and peeled potatoes, potato crisps , extruded snacks such as potato; b, processed into starch and related products: potato starch as a result of the excellent features, not only is the production of high-level instant noodles, flour add the most ideal type of starch, but also meat, surimi products such as additives or raw materials . Potato starch is also of high quality raw materials. The potato starch, but also related products available, including a variety of modified starch, maltose, glucose, dietary fiber products. C, other products: potato residue after starch extraction can be made from potato fermented feed, extract protein
Skin peeling (for) of fruits and vegetables processing to remove need not eat or not, and improve the physical appearance of the product. The main factors including through minimize removed part and may reduce the labor and material costs energy, reduce the total cost. Here introduces friction peel method: food is placed on the walls or emery roller drum lined up in the emery, wear away the food of skin surface by the amount of water after washing clean. The advantage of this method is due process is conducted in greenhouse with low cost and the energy of capital cost is low, no heat, the advantages of good food appearance, irregular food surfaces (such as potato "holes) destroys peel product appearance, need manual removal.   

Key words: Potatoes、Peel cleaning、Agricultural、Food machinery
