Raw material:  low-temperature soybean meal
	         Product: soybean  protein isolate 
	         By-product: soybean  dietary fiber 
	         Purpose: food  additives, health products raw materials (protein content>90%).
	         Process features:  this process uses alkali soluble and acid precipitation process to isolate  fiber and protein from low-temperature soybean meal. Protein through  homogenizing, high temperature sterilizing, spray drying to produce soybean  protein isolate. The protein content is high, the water consumption is large,  and it is required to provide with water treatment facilities.
