摘　　要：介绍了采用管式反渗透膜浓缩牛奶的工艺,研究了工艺中的压力、温度、浓度和浓缩过程与牛奶中有效成分的截留率之间的关系,同时也研究了压力、温度、浓度在浓缩过程中与膜通量之间的关系。实验结果证明,管式反渗透膜对有效成分的截留率接近100%。The tubular reverse osmosis membrane milk processing was introduced. The relationship between pressure, temperature, concentration and retention rates of valuable components were studied.Also the relationship between pressure, temperature, concentration and permeate flux in concentrated process were studied with a tubular reverse osmosis module. Experimental results proved that the retention of valuable components of this system was approximation 100%.
