摘要
目的:为解决传统油脂精炼方法存在的问题,研究无机陶瓷膜技术在油脂精炼中的应用。方法:从无机陶瓷膜的截留分子量、压力、温度和混合油浓度研究磷脂、色泽、酸价和膜通量的影响。结果:最佳膜技术处理工艺条件为陶瓷膜2万、压力0.3MPa、温度40℃、混合油浓度50%,经过处理,磷脂含量降到6.86mg/kg,色泽为Y5.2(25.4mm比色槽),酸价为0.63。结论:无机陶瓷膜技术应用到油脂精炼中,可简化油脂精炼工艺、减少能耗、降低生产成本、节省脱色吸附剂的用量,达到脱胶、脱酸和脱色的目的。
Object： Inorganic ceramic membrane was investigated for oil refining in order to solve problem of traditional refining. Methods： The effect of phospholipids content, colour value, acid value and flux of membrane were studied from molecular weight of cutting off, operational pressure, temperature and mix concentration. Results： The optimization condition as follow： 20000 molecular weight, 0.3 MPa at 40 ℃, the mix concentration was 50%. Throughout the treat, content of phospholipids dcreased 6.86 mg/kg, colour value was Y52（25.4 mm slot）, acid value was 0.63. Conclusion： Refining oil by using Inorganic ceramic membrane had good effect on degumming, deacidfying and decoloring, with simplifying process of oil refining, discussing the cost of production.
