对影响豆腐皮形成的因素进行探讨，研究传统砂磨与胶体磨、料水比、磨浆次数及细度对出浆率的影响；通过正交试验表明：采用多级分离技术进行连续浆渣分离处理，即第1次采用砂轮磨磨浆，加水量为干大豆重量的4．5倍，浆液通过80目绢布过滤后得所需豆浆，第2次采用胶体磨磨浆，加水量为干大豆重量的3．5倍，随后浆液通过100目绢布过滤后得所需豆浆，能充分提取豆渣中的蛋白质，提高大豆可溶性成分的得率和产品品质，其豆腐皮产率达56．3％。

Despite efforts attempting to increase the protein extraction rate from soybeans in dried soybean sheet production,the recovery rate remains less than 50%.This article reviews the factors affecting the yield,and presents the results from our experimentation targeted at the soybean-milling and slurry-filtration of the protein extraction prior to sheet formation.The traditional sand and colloid grinder milling methods,ratio of soybeans to water,milling time and particle size were examined.The orthogonal experimentalresults showed that a multiple stage separation should be used for the process.A maximized protein recovery could be obtained by a two-stage filtration:firstly,using the sand milling with a water/soybean ratio of 4.5/1 to grind the soybeansfollowed by filtration through a 80 mesh silk cloth;then,applying the colloid grinder with a water/milled slurry ratio of 3.5/1 followed by filtration through a 100 mesh silk cloth to collect the soy milk for sheet-making.The yield of soluble matters and quality of soy milk were significantly increased resulting in 56.3% increase on the dried soybean sheets.
