摘要
对油脂碱炼过程中的水洗废水直接在脱胶工序中应用进行研究。通过单因素与正交试验,确定了最佳工艺条件:水洗废水添加量为油重15%,脱胶时间30 min,脱胶温度75℃,搅拌速度60 r/min,在此条件下,得到脱胶油的磷含量为22.8 mg/kg。同时,采用水洗废水脱胶,生产每千克成品油可节省能量(35～37)kJ。
In this study, washed wastewater from lipid alkali refining process was applied in the degumming process. Through the single factor and orthogonal tests, the optimum conditions were determined as follows： washed wastewater amount, 15% of lipid; the degumming time, 30min; the degumming temperature, 75℃; the stirring speed, 60 r/min. The phosphorus content of the obtained degumming lipid under the above conditions was 22.8 mg/kg. Meanwhile, （35-37） kJ was saved when producing one kilogram oil product.
