The Ultimate Guide to Soy Protein Powder Process Design

With the rapid development and high intensification of the global feed breeding industry, the demand for processing and investment in soybean protein isolate powder is increasing. As the main source of plant protein, soybean meal occupies an important position in feed production and animal breeding. However, soybean meal also has the characteristics of low digestibility, many anti-nutritional factors, and weak functionality, which limit the application of soybean protein, especially in young animals.Therefore, processing soybean meal through a certain technology design to remove anti-nutritional factors while improving the digestibility of soybean foil protein and improving its functionality is an effective way to improve the fen utilization rate of soybean protein isolate.

Soybean Protein Powder Processing

The Production Status of Soy Protein Powder

Soy protein isolate powder is a nearly purified protein extracted from soybeans through a series of processing steps. Soy protein isolate contains eight essential amino acids, which are similar to meat, fish, eggs, and milk, and are full-price proteins. Studies have shown that protein is the material basis of life and one of the three major components of the human body. The lack of protein will directly lead to growth retardation, weakened immunity, loose skin and premature aging.

At present, the production of soy protein isolate powder has just started in the world, there are not many manufacturers, and the production technology needs to be improved.From the perspective of production technology and processing methods, with the help of the existing domestic equipment for the production of protein isolate by the alkaline immersion and acid precipitation method, the production technology of various manufacturers is absorbed and the appropriate production technology is adopted. It can produce qualified soybean protein concentrate products, and have better social and economic benefits.

Processing Conditions of Soy Protein Isolate Powder

The quality requirements of the soy protein isolate product are: uniform surface color, no hardness, full of elasticity, water and oil absorption, etc. Through several years of production practice, we have realized that in order to produce soy protein isolate that meets the above requirements, there must be strict requirements from raw materials to processing. The following are the production conditions of soy protein isolate powder for the reference of investors who want to invest in the soy protein processing industry.

• High-quality soybeans must be selected as raw materials, and the soybean grade must at least reach the national third-level standard;
• Before processing defatted edible soybean meal, soybeans must be repeatedly cleaned to remove various impurities;
• Remove bean curd and bean curd. There are impurities, bacteria, oxidase, etc. on the surface of bean curd and bean curd. At the same time, most of the soybean hull is fibrous tissue, so it must be removed during the pretreatment process;
• Soybean drying temperature control standard is not to exceed the critical temperature of protein denaturation, and the general control temperature is not to exceed 70 degrees;
• In the production process of edible soybean meal, a low temperature or flash evaporation process must be used to ensure that protein denaturation is kept to a minimum.

The Processing Design Of Soy Protein Powder

Main processing procedures of low temperature bean foil processing workshop

• Cleaning (screening and selection): screening and removing iron impurities, large impurities, straw, stones; selecting and separating adzuki beans.
• Conditioning: Adopt low-denaturation drying tower and fluidized bed for rapid drying, which can not only ensure the peeling rate of the peeling process, increase the protein content, but also ensure the invariance of soy protein.
• Dehulling: Use a dehulling machine and a kernel separating screen to remove the hulls of soybeans to increase the protein content of soybean meal.
• Softening: improve the plasticity of soybean raw materials, make the embryo rolled by the embryo rolling machine thin and not broken, thereby improving the leaching effect.
• Rolling billet: A hydraulic tight-rolling billet mill is used to better destroy the cell structure of the oil to ensure that the rolled billet is thin and uniform, tough, and small in powder.
• Leaching: advanced drag chain extractor, stainless steel grid plate, frequency conversion speed regulation for feeding and discharging, automatic control of feeding material level, which can ensure stable production.
• Low temperature desolventizing: adopts digestion and absorption of international and domestic advanced technology, and adopts AB cylinder desolventizing process, which has a thorough desolventizing effect and energy saving.
• Mixed oil evaporation: The evaporation system adopts negative pressure evaporation to make full use.

Main processing procedures of soy protein isolate workshop

• Dissolution extraction: using the dissolving properties of soybean protein, using a weakly alkaline aqueous solution (NaOH) to soak low-temperature defatted soybean meal to extract soluble proteins and low-molecular-weight sugars, and then use a centrifuge to separate insoluble fibers and solid residues;

• Acid precipitation process: Use a certain amount of aqueous hydrochloric acid solution to adjust the pH value of the dissolved protein solution, and then separate the precipitated protein gel with a centrifuge;

• Neutralization, homogenization, sterilization and spray drying: The separated protein is homogenized, sterilized, vacuum flashed and pressurized and then spray-dried to obtain soy protein isolate powder.
