Protein Separation Techniques Details

Raw Material Pretreatment


Soyabean Pretreatment Flow

  • Cleaning section: to remove the iron impurities, large impurities, stalks, and stones.
  • Tempering section: to increase the protein content, ensure the invariance of soybean protein.
  • Peeling section: to remove the skin of soybeans to increase the protein content of soybean meal.
  • Softening section: to improve the plasticity of soybean raw materials, improving the leaching effect.
  • Flaking section: to destroy the cell structure of the oil, ensuring that the rolled billet is thin and uniform.

Low Temperature Solvent Extraction Process


Solvent Extraction Process FLow

Advanced drag chain extractor, stainless steel grid plate, frequency conversion speed regulation for feeding and discharging, automatic control of feeding level, stable production, low residual oil in meal, and low dissolution consumption.

Soya Protein Separation Process


Soya Protein Separation Process Flow

  • The first step is to dissolve and extract. Utilizing the solubility characteristics of soybean protein, use weak alkaline aqueous solution (NaOH) to soak low-temperature defatted soybean meal to extract soluble proteins and low molecular sugars, and then use a centrifuge to separate insoluble fibers and solid residues.

  • The second step is acid precipitation, add a certain amount of aqueous hydrochloric acid solution to the dissolved protein solution to adjust its pH, and then use a centrifuge to separate the precipitated protein gel.

  • The third step is neutralization, homogenization, sterilization and spray drying. The separated protein is homogenized, sterilized, vacuum flashed and pressurized and then spray dried to obtain a powdered soybean protein isolate product.

Protein Dry Area

Soya Protein Drying Area

The drying tower machine is mainly used to dry the materials coming from the protein wet area. The key point of the drying tower is temperature control. Temperature will directly influence the quality of the protein and whether the main tower is deformed.

Advantages of Setting Up Soya Protein Separation Plant

  • Health benefits of soya protein. There is 35% of protein in the soybean, and with soya protein, you can reduce the amount of neutral fat in your body and lose weight, meanhile effectively preventing the risk of heart disease, reducing the risk of cardiovascular disease and  enhancing immunity and exercise ability.

  • Wide applicaiton of soya protein. As an important food additive, soy aprotein can be used in wide fields, like sausages, hamburgers, shaomai food to effectively protect oil and water, and provide special taste of meat products. 

  • High return of soya protein separation techniques. From the picture above, we can see the soya has wide produciton area in the world, meaning that high demand of soya protein methods. If you have enough raw materials and budget, it is suitable for processing soya protein for sale, or for investment.
