随着食品工业的发展,食品深加工已越来越被世界重视,特别是便餐和方便食品的诞生,促使保鲜脱水蔬菜工业迅速发展起来,这便要求原材料的深加工伴随着发展。其中,马铃薯的深加工就是受到人们高度重视且发展较快的产业之一。
我国是马铃薯主要生产国,年种植面积和总产量居世界第二位,但在我国绝大部分马铃薯被直接用作饲料或食用。由于每年仅有百分之几用于深加工,致使鲜薯过剩,增加了越冬保鲜难度,也降低了它的营养价值。究其原因是缺少加工设备,特别是去皮机械。而从国外引进设备,价格昂贵,生产成本高,致使国内该产业发展较慢。马铃薯去皮是所有马铃薯制品加工工艺过程的重要环节,目前存在的各种去皮方法都有其一定的局限性。随着马铃薯产业的发展和我国社会经济的进步,如何寻找一种优质、高效、节能、环保的马铃薯去皮方法已成为马铃薯加工工艺过程中迫切需要解决的问题。

Abstract
Along with the development of food industry, food processing by the world has e more and more attention, especially te and the birth of the convenient food, prompting fresh dehydrated vegetable industry rapidly, it will request the intensive processing of raw materials with development. Among them, the potato is deep processing by people attaches great importance to the development of the industry and one of fast.
Our country is the main producers of potatoes, years of planting area and total production ranking second in the world, but in our country most potatoes were directly used for feed or edible. Because only each year a few used for further processing, and the fresh potatoes excess, increases the difficulty of keeping fresh winter, also lowered its nutritional value. Investigate its reason is lack of processing equipment, especially to leather machinery. And equipment introduced from abroad, the price is expensive, high production costs, which the industry development in more slowly. Peel potatoes all potato products processing technology is the important part of the process, the existing various to skin method has its certain limitation. Along with the development of the potato industry and China's social and economic progress, how to search for a high quality, highly effective, the energy conservation, the environmental protection potatoes peel potatoes methods have been the machining process of the urgent need to address the problem.
