摘要
虽然薄膜分离技术在玉米湿磨工业中是比较新的生产工艺,但它正迅速发展成为一种可用于组分浓缩、提纯及分离的十分重要的方法。这不仅能提高蒸发器的生产能力,而且节能、节水,减少环境污染。描述了微滤、超滤、纳滤及反渗透薄膜分离机理;重点介绍了薄膜分离技术在浸渍液浓缩,蒸发器顶流出物处理、玉米胚芽油加工、玉米蛋白质分离及玉米淀粉洗涤、脱水和浓缩等玉米湿磨工艺中的应用前景。
<Abstrcat>Although membrane separation technology is a relatively new process in corn wet milling industry,it is rapidly developing into a significant method for concentration,purification,and separation of components.Its application can not only increase the capacity of evaporators but also save energy and water,reduce environmental pollution.This article describes membrane separation mechanisms of microfiltration(MF),ultrafiltration(UF),nanofitration(NF)and reverse osmosis(RO).The application prospects of membrane technology for steep water concentration,treatment of evaporating water overhead,corn oil processing,protein separation,starch washing,dewatering and concentration in cron wet milling industry are emphatically introduced.
