摘　　要：采用水化低温长混工艺,避免棉酚变性,棉油色泽固化,使油皂易于分离。毛油经预处理、除杂、脱胶后,在棉籽油离心脱皂前,加入适量浓度的食盐溶液。该工序降低了皂脚夹带的中性油含量,提高了棉籽油精炼率。In order to avoid the degeneration of gossypol,color curing of cottonseed oil,and separation of oil from soapstock,the alkali refining process with low-temperature and long-mixed was adopted.After being pretreated,cleaned and degummed,before centrifugation to desoap,a right amount of salt solution was added into the crude oil.The process not only reduced the content of neutral oil in the soapstock,but also increased the refining rate of cottonseed oil.
