Leaching of cotton seed oil as raw material, using cotton seed oil refining process of cotton seed oil. The process refining yield is high, can be used for reference in the oil production enterprises in selecting refining process. Keywords: cotton seed oil level; Cotton seed oil refining; The process flow Cotton seed oil contains fatty acids and other oils and fats, saturated fatty acid in 6% ~ 7% is C20 more fatty acid, determines the nature is different from any other oil. By leaching of cotton seed oil as raw material to the afterlife ChanMian seeds oil, cotton seed oil refining process, can improve the yield of cotton seed oil refining, achieve the goal of increase enterprise economic benefits. Now it introduces the technological process and the problems that should be paid attention to, for your reference. 1 process 1.1 physical refining process hot water vacuum system clay steam left left left left leaching of cotton seed oil filter degumming to vacuum drying to decolorization, deodorization, cotton seed oil left left left left down down down
1.2 process explanation 1.2.1 to remove impurities In order to reduce the loss of cotton seed oil refining, raise the yield of cotton seed oil in the refining process, leaching of cotton seed oil must first to remove the impurities. Generally adopt hair oil filter to remove impurities, the leaching amount of impurity control under 0.2% cotton seed oil, which can improve the efficiency of degumming section. 1.2.2 degumming by batch process, the cotton seed oil heating to 80 ~ 85 ℃, and water according to pectin content in oil of MAO, generally 3 ~ 5 times of the colloid content, water temperature at 85 ~ 90 ℃ (above the oil temperature 5 ℃). Water in 40 ~ 60 m in finish, with 60 ~ 70 r/m in the process of adding water in mixing, add water after stir 3 ~ 5 m, in precipitation let stand for 2 ~ 4 h. sampling 280 ℃ heating
