The paper describes the use of ultrafiltration membrane separation of whey in the whey protein,ion exchange resin to extract Sialic acid and remove impurities in the lactose solution and aromatic polyamide spiral reverse osmosis membrane to concentrate whey protein.The reverse osmosis process parameters affecting the results of the reverse osmosis concentrate for the lactose were determined by operating pressure,temperature,flux,concentration ratio and other factors.The use of aromatic polyamide spiral reverse osmosis membrane unit,the operating pressure of 0.5 MPa,the operating temperature of 40 ℃,lactose retention rate of 95% single-stage about lactose product quality indicators,in line with the relevant national standard.The crystallization process compared with the existing,is less pollution,less energy consumption,higher yield with good prospects of development.
