Abstract
The efficiency of the removal of bacteria in skim milk and some critical parameters with ceramic membrane(GP 0.8 and 1.2 μm) were studied in this article.The result showed,that using membrane separate technology with ceramic membrane(GP 0.8 and 1.2 μm) was high efficient in bacteria out-moving,the retention rate were above 99.5%.When the temperature of skim milk is 50 ℃,and Volume Concentration Ratio(VCR)=20,by using the ceramic membrane(GP 0.8 μm),the retention rate of protein can be reached at 10% and the membrane flux was 300 L/(m2·h).
