花生紅衣脫皮機(jī)的設(shè)計
摘 要: 花生仁是由紅色外衣和籽仁組成。紅衣主要是纖維組織和止血素, 而花生中的油脂、蛋白質(zhì)等營養(yǎng)素都集中在籽仁中。無論是從花生中提取蛋白粉, 還是提高花生榨制出濃香型花生油的檔次, 都需將花生果經(jīng)剝殼后再去掉花生果仁上的紅皮(俗稱紅衣), 這是制作上述食品及原料加工過程中不可缺少的關(guān)鍵工序之一[1]。為此，我們需要設(shè)計與試制一種花生脫紅衣機(jī)來除去花生紅衣為后續(xù)的工作做準(zhǔn)備。本文通過利用搓擦原理將花生仁上的紅衣去除的方法，闡述了通過搓擦的原理可以將花生仁上的紅衣有效的脫離下來，并且花生仁的破碎率小[2]。通過實驗論證了可以利用兩膠帶之間的搓擦使花生仁上的紅衣有效的脫離下來，可廣泛的應(yīng)用于花生的初加工。

A Design on Peanut Red Skin Huller
Abstract: A peanut kernel is composed by a red skin and a kernel. The skin is mainly made up of fibrous tissues and stypticins, while the kernel mainly contains nutrients like fat and protein. No matter whether the peanuts are used to extract albumen powder or used to enhance the quality of the extracted strong flavor peanut oil, the red one (generally called red skin) covering the kernel should be peeled after the peanut is shelled, which is one of the essential key procedures in making the products and material processing. Therefore, we need to design and trial-produce a peanut red skin huller, in preparation for the subsequent procedures. So, throughout the paper, the designers stated that rubbing principle could be applied in taking off the red skin and expounded how it worked effectively with low broken rate. By experiments, it has been expounded and proved that the red skin can be dropped successfully with the rubbing between the rubber belts, which can be widely applied in the primary processing of peanuts.
