Soybean oil pretreatment and pressing machine will have the process section of cleaning, stones removal, magnetic selection, crushing, softening, flaking, drying and so on.

We manufacture 5-2000TPD soybean oil pretreatment and pressing machine.

Introduction of Soybean oil pretreatment and pressing machine

Soybean pretreatment is the important section to remove impurity caused during soybean harvest, transportation and storage. Before soybeans enter into oil production plant, further cleaning is necessary in order to reduce impurity content within the scope of technical requirements, and ensure soybean oil production process result and finished soybean oil quality.

Process Flow Chart of Soybean Oil Pretreatment Plant:

Process Introduction of Soybean Oil Pretreatment Plant:

Magnetic Separation: It adopts magnetic power to remove magnetic metal impurity which in soybean raw materials.

Soybean Cleaning: It removes inorganic impurities, organic impurities and oil impurities which are inside soybeans.

Soybean Conditioning: It can regulate moisture and temperature of soybean until softening, which can increase ductility of soybean. Soybean is the low oil content oilseeds with hard structure, thus powder control is important for convenience of further soybean oil extraction plant.

Soybean Crushing: Mechanical method can break soybean into small particles. Roller crusher is adopted to crush soybean for convenience of soybean flaking process.

Soybean Flaking: It covers pressing process from the granular formation into sheet. The purpose of soybean flaking is to destroy soybean tissue, create condition for steaming and roasting, make easily oil separating in soybean oil solvent extraction. Soybean flaking requires thin embryo, uniform surface, less powder, no oil reveal. Powder controls at 1mm mesh sieve material not exceed 10-15%, soybean flakes to 0.25-0.35mm.

Soybean Extrusion: Soybean extrusion uses extrusion equipment to crush, flake, and change soybean into porous puffed pellets.
