Soy Protein Machine

What Is the Function of Full Automatic Extruded Soy Nuggets Production Line?

Soya protein making machine extruded soya nuggets production line is a new kind of inflating processing line, which is produced and developed according to rich experiences and the requirement of food market. Full automatic Soya Nuggets production line processes low temperature soya meal, peanut meal, wheat gluten and isolate soy powder as raw material to make meat-like food with high protein content. Through feeding materials, extruding, cutting, drying, packing,the finished products are done once time fully automatically. And by changing the cutters, it can produce different kinds of shapes of soya food to meet customer requirements.

Running in a high automation and intellectualism, no pollution
Apply a linker to connect with the air conveyor ,which can directly inline with filling machine.

Soy Protein Isolate Production Process

The production of soy protein isolates has strict requirements, so every process should be carefully designed and checked to ensure the quality of final products. Below introduces the soy protein isolates production process in details: 

Soybeans Pretreatment Process
●Cleaning (Selection & Screening): Selection is to separate soybean beans and screening is to remove iron impurities, large miscellaneous, straw, stones;
●Conditioning: Using a low-denature drying tower and fluidized bed for rapid drying, which not only ensures the peeling rate of soybean peeling process to increase the protein content, but also guarantees the invariability of the soy protein.

●Peeling: Peel the soybeans with a peeler and a seed screen to increase the protein content in the soybean meal.
●Softening: Improve the plasticity of the soybean material, so that the flakes rolled by the flaking machine are thin and not broken, thereby improving the extracting effect.
●Flaking: The use of compact hydraulic roller mill can better destroy oil cell structure, to ensure that the rolled flakes are thin and uniform, ductile, and low degree of powder.

Low Temperature Soybean Meal Processing Technology
●Soybean Meal Extracting: The pretreated soybeans are loaded into solvent extraction tank to get the low temperature meal and crude soybean oil. The machinery for soy protein extraction plant is advanced towline extractor, stainless steel grid, frequency control of feed and discharge material, feed material level automatic control, stable production, low residual oil, low solubility.

●Low Temperature Desolvation: It adopts digestion and absorption of world advanced technology: A+B tank desolvation process. The low temperature soybean meal obtained from this technology has high NSI (nitrogen solute index), uniform and complete flake, complete desolventization effect, and energy saving.
●Mixed Oil Evaporation: Evaporation system uses negative pressure evaporation, using 1st steaming, energy saver, jet heat exchanger, oil-and-oil heat exchanger to make full use of the waste heat of the secondary steam of evapo-separated machine, jet pump exhaust gas and raw oil, which is advanced and energy-saving.

●Solvent Recovery Cycle: Most of the solvent gas is recovered, recycled after water diversion, while the tail gas containing trace amounts of solvent enters the tail gas recovery system.
●Tail Gas Recovery: Tail gas paraffin absorption system can effectively intercept difficult-to-condense solvent gases, and the scientific and advanced condensate system configuration ensures good process indicators.

Soy Protein Isolate Production Process
●Disolving Extraction: The soluble protein and low molecular sugar were extracted by soaking low temperature defatted soybean meal with weak alkaline water solution (NaOH), and then separating insoluble fibers and solid residue by centrifuge.
●Acid Precipitation: Add a certain amount of hydrochloric acid solution to the dissolved protein solution to regulate its pH value, and then use centrifuge to separate the precipitated protein gel.
●Neutralization, Homogenization, Sterilization and Spray Drying: Homogenize and sterilize the separated protein, then vacuum flash evaporation and pressurization and spray drying, to get the powder soy protein isolate product.
