摘要
研究了陶瓷膜在薏苡仁混合油脱胶中的应用。研究了不同截留相对分子质量陶瓷膜的脱胶效果以及过膜压力、料液温度和运行时间对膜通量的影响,并对陶瓷膜清洗工艺进行探索。选择截留相对分子质量15000的超滤膜,在50℃和0.5MPa下能够去除混合油中90%磷脂。用碱洗和次氯酸钠清洗能够彻底去除膜污染,恢复膜通量。
Degumming of coix lachryrna-jobi seeds miscella （CLSM） was studied by using ceramic ultrafiltration （UF） membrane. The degumming results of different molecular weight cut-off （MWCO） ceramic ultrafiltration membranes were compared. The effects of trans-membrane pressure, temperature and operation time on membrane flux were studied. Over 90% lecithin in CLSM could be removed, when it is ultra-filtrated by the MWCO of 15000 UF membrane at 50℃ and 0.5MPa. The membrane flux could be completely recovered by means of proper cleaning procedures of using sodium hydroxide and sodium hypochlorite successively to remove the pollutants.
