对超滤分离后的柑桔汁进行反渗透浓缩研究.实验找到了适合柑桔汁浓缩的反渗透膜RO-1,同时确定反渗透浓缩的适宜工作条件为:p=4.5MPa,T=40,S=1m/s,柑桔汁可浓缩到 23°Bx. 分别用0.1% NaOH和0.5% U10溶液清洗反渗透膜,其膜通量能完全恢复.通过分析比较柑桔原汁和浓缩汁的营养成分得出结论:膜分离技术浓缩柑桔汁切实可行.

Reverse osmosis(RO)concentration of orange juice separated by ultrafiltration was researched.Results indicated that membrane RO-1 was the right membrane for orange juice RO concentration.The optional RO operating conditions are P=4.5MPa,T=40 and S=1m/s and orange juice was concentrated to 23°Bx in this condition.Both 0.1%NaOH and 0.5%U10 solutions are excellent scurs for RO membrane washing.Ingredients of mixed juice after separation and concentration were analyzed and the conclusion was that orange juice ...
