摘　　要：采用膜分离工艺代替传统的过滤工艺分离长链二元酸发酵液。发酵液经过陶瓷微滤膜、卷式超滤膜过滤后,除去菌丝体、蛋白质、色素及杂质,澄清透明的透析液直接进行酸化结晶,即可得到合格产品。使用膜分离工艺不仅可以简化操作、降低劳动强度,还可以提高产品质量和收率,降低生产成本。Membrane separation process is applied in binary acid fermentation liquor separation instead of the traditional fil- tration process. The fermentation liquor is filtered through ceramic membrane and roll membrane, and the mycelium, proteins, pigments and impurities are removed. The clear and transparent dialysate is obtained and crystallized by direct acidification and then qual{f^ed products are obtained. Use of membrane separation technology can not only simplify operation and reduce labor intensity, but also improve product quality and product yield, so production costs can be reduced.
