摘    要:有杉超滤波分离新设备-Sun-flo超滤膜膜分离系统一步截留不经预处理的维生素C发酵液中的菌丝体、蛋白质和悬浮 体颗粒等杂质,滤液质量高,过滤收率高达99.24%,在超滤提纯古龙酸的过程中,系统的膜通量可达99.49LMH,且膜通量随超滤时间的延长衰减得极为缓慢,表明Sun-flo超滤膜分离系统完全能克服发酵液不经预处理产生了严重膜堵塞的现象,大大简化了操作工艺流程,降低了生产成本,将该系统应用于工业生产,在技术上完全可行,在经济上亦将为企业带来最大效益。

关 键 词:超滤 提纯 维生素C 发酵液 2-酮基-L-古龙酸 膜分离

Abstract:In this paper, a new ultrafiltration pilot-Sun flo membrane separation system was used to extract gulonic acid from Vitamin C fermentation liquor that was not pretreated. The quality of filtrate was high and the filtering yield was as high as 99.24%. The average flux was 99.49 LMH and the flux declined very slowly during the purification of gulonic acid by Sun flo membrane separation system. The results showed that the Sun flo membrane separation system could overcome the phenomenon of membrane jam seriously. The processes could be simplified greatly.
Keywords:ultrafiltration  extraction  Vitamin C  2 Keto L gulonic acid  fermentation liquor
