7500t/a Soy Protein Isolate Production Line

Located in high-tech debelopment zone of Jining city of Shandong province, our company is close to Mountain Tai in the north and next to Weishan Lake in the south. Beijing-Shanghai high-speed railway and Grand Canal all run through the city. There is expressway connecting our company directly to Qingdao port. In addition, Jining airport has opened multiple airlines to Beijing, Shanghai and Guangzhou. To sum it up, the traffic is very convenient.

1. Raw Materials: low-temperature soybean flakes

2. Products: soybean protein isolate (protein content is higher than 90 percent)
2.1 By-Products: soybean dregs (used for production of soybean dietary fiber)

                                             Soybean protein isolate production line (annual capacity: 20,000 tons SPI)

3. Applications
3.1 Severing as a kind of food additive, soybean protein isolate is able to efficiently improve the protein content of the food, thus improving food functional performance.
3.2 SPI is also suitable for production of health care products.
3.3 It can be used for production of environment friendly binding agents as well.

4. Process Description
We make use of alkali-solution and acid-isolation extraction process to separate fiber and protein from low-temperature soybean flakes. Then, separated protein solids go through high pressure homogenization, high temperature sterilization and spray drying to produce protein isolates.
