Protein is one of the most basic substances in human life activities. The main source of protein in people's diet is animal protein and plant protein.
Soy protein isolate is one of the best among plant proteins, especially in Northeast China, where soybean resources are abundant and soy protein has a high nutritional value.
It has far-reaching significance to develop and produce soy protein. However, the polymer structure and biochemical properties of soy protein are extremely complex and sensitive to environmental factors.
Any difference in the production process can lead to changes in the structure of the protein, thereby changing its functionality, nutrition, biochemical properties, etc. . Therefore, the production of high-quality soy protein is a complex system that needs to be controlled from each production point in the process.
In the process of producing soy protein, the application of acid precipitation method is relatively complete. After pretreating the soybeans, the oil is leached, defatted and extracted soybean meal, and then the soybean protein is extracted in an alkaline solution. Finally, acid is added to separate the protein by aggregation and precipitation.
The separation of residue and liquid is a key process to improve the yield and quality of protein.
In the entire production process, there are three separation processes: separation of bean dregs and extract, separation of protein aggregates and serum, and protein curd and washing.
At present, a high-speed decanter centrifuge is generally used to improve the protein recovery rate. After the extracted solution is passed through the decanter centrifuge, the bean dregs and soy milk can be directly separated.
According to different separation requirements, different soybean protein separators can be selected, our company produces a wide range of decanter centrifuges with strong selectivity,different models can be selected according to the specific production capacity and designed according to customer requirements.
The entire feeding, separation, and discharging are completed in an automatic, continuous, and closed state.
