Soy protein isolate production line
Process Description:

 

 

The process principle is on the basis of alkali dissolution and acid precipitation as follows:

 

1. Low temperature soybean meal

 

Low-temperature degreased soybean meal is firstly measured, then conveyed to extraction section.

 

2.Alkali soluble extraction

 

 

Initially white flakes mix with extracting solution in 1st stage extracting tank for a specific reaction time. Then mixture is pumped into horizontal screw decanter centrifuge for separating bean dregs which will be conveyed into 2nd stage extracting tank for further extraction. Mixture is pumped into horizontal screw decanter centrifuge for separating bean dregs which will be conveyed to drying section.

 

3 Acid Precipitation and Neutralization

 

Flowing acid precipitation, i.e. soybean milk is pumped into static mixer to react with a certain proportion of hydrochloric acid. Mixture is then pumped into acid precipitation tank, horizontal screw decanter centrifuge for separating curd which will be then pumped into water washing tank. Washed curd is pumped to neutralization section by rotor pump. Neutralizing tanks can be used interchangeably to achieve continuous production.PH value can be adjusted to neutral by neutralization of curd and dilute lye in neutralizing tanks.

4. Flash sterilization

 

Curd is pumped into filter for removing impurities by pressure pump, then into sterilizer for instant sterilization and flash tank for concentration. Finally curd is pumped to homogenizer, then to drying section by high-pressure pump.

 

5. Drying

 

Curd is pumped into spray drying tower by high-pressure pump in which curd is turned into soybean isolated protein particle, then into cyclone separator by pneumatic transmission. Finally soybean isolated protein particle treated by screener is conveyed to finished product packing machine by pneumatic transmission.
