一种恢复超滤膜通率的方法
摘要：
本发明公开了一种恢复超滤膜通率的方法，通常苹果汁的加工工艺包括：清洗、鲜榨汁、糊化、酶解、超滤、浓缩、成品、包装、清洗超滤膜，其特点是在酶解工艺中加入复合生物酶；在每天的常规化学清洗之前进行1小时的复合酶清洗，另外每周增加一次酸清洗，其恢复超滤膜通率一般在20－30％，是一种效果很好的恢复超滤膜通率的方法，同时提高了产量降低了成本。
摘要（英）：

The invention discloses a method for recovering the venting rate of hyperfiltration membrane, and normal process for preparing apple juice comprising the following steps: cleaning, juice squeezing, gelatinizating, enzymolysis, hyperfiltration, concentration, product finishing, packing, and cleaning the hyperfiltration membrane, which is characterized in that adding complex biological enzyme during enzymolysis process, cleaning complex enzyme for an hour before normal chemical clean of everyday, and cleaning with acid in every week, as a result of which the recovery rate for venting rate of hyperfiltration membrane is about 20-30%, and productivity is increased and cost is reduced.
