Soybean Protein Production
Soybean protein can be classified ordinary soybean protein ,soybean concentrate protein and soybean isolate protein, normally the ordinary soybean protein can be used as animal feed, the concentrate soybean protein can be used in edible food, the isolate
Normally our machine can make the ordinary soybean protein and soybean concentrate protein.
The ordinary soybean protein production process is:
Pretreatment------Solvent Extraction-----Wet meal Desolventizer----Dryer
The soybean concentrate protein production process is:
Pretreatment-----solvent extraction----low temperature desolventizer----grinding flakes into powder
Normally, the whole process needs to do in a low temperature to keep the protein component unchangeable,also in the pretreatment process, the dehulling need two times at least,and must be at low temperature to do the desolventizer process.
Soybean protein isolate
1) Function: Soybean Oil Refinery Machinery is an oil extractor through soaking or spraying pre-pressed cake by a certain organic solvent. The principle of this part is the different solubility of solvent.
2) Use range: Soybean Oil Refinery Machinery fits for pre-press extraction of high-oil- content materials and direct once time extraction of low-oil-content materials.
3) Main parts: Soybean Oil Refinery Machinery includes rotary extractor, toaster, 1st evaporator, 2nd evaporator, stripping tower, condenser, etc.
2. Main parts of soybean protein isolate
1).Vegetable protein have incomparable nutrition and functional characteristic compared with animal protein,vegetable protein has been widely used in food and feed industry recently.And deep processing productions including high-protein food,reducing-weight food and protein membrane are developed.that preparation of protein concentrate and protein isolate using low tempreture desolventized meal has wide using.
2).Soybean protein concentrate(SPC)is made of high quality soybean meal witch removing the solubility in water or alcohol solube nonprotein part,the protein content is more than 65%(dry basis)and the protein(N*6.25) of soy protein products.
3).Soybean Protein Isolate (SPI) is based on soybean as raw material,using the advanced processing technology to make high protein of 90% or more of the functional food additives,which has a good solubility and emulsification,super bubble,water keeping and viscoelasticity,and both have high nutritional Protein,so it is widely used in meat products(such as western-style ham,sausage,lunch meat,sandwich,enema,sausages and meat,etc.),cold drink products(such as ice cream,cream,ice cream,pudding,etc),baked goods,(such as bread,cakes,etc.).
3. Characteristics of process production：
1. Using low-temperature soybean meal and secondary extraction to ensure a product yield of 34-41%, up to 41% (2.7 tons-3 tons of low-temperature meal to extract 1 ton of protein powder).
2. Adopt enzymatic hydrolysis and secondary granulation technology to make the product quickly produce gel, improve the solubility, dispersion and dusting of the product, and the product level has reached the international advanced level.
3. The production process is simple and easy, the product quality is stable, and the workers are easy to master the operation.
4. The overall design is optimized, and the important production links are automatically controlled.
5. Continuous sterilization and deodorization to minimize the beany flavor of the product.
6. The whole set of production equipment meets food hygiene requirements, and the parts in contact with materials are made of stainless steel.
7. Less equipment investment.
