Soybean oil pretreatment machine introduction:
Soybean oil pretreatment is an 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 of soybean oil preparation: Soybean → cleaning → stones removal → magnetic selection → crushing → softening → flaking → drying → to extraction workshop.
1) Magnetic Separation: It adopts magnetic power to remove magnetic metal impurity inside soybean raw materials.
2) Soybean Cleaning: It removes inorganic impurities, organic impurities and oil impurities inside soybeans.
3) Soybean Conditioning: It can regulate moisture and temperature of soybean until softening, which can increase ductility of soybean. Soybean is low oil content oilseeds with hard structure, thus powder control is important for convenience of further soybean oil extraction.
4) Soybean Crushing: Mechanical method can broke soybean into small particles. Roller crusher is adopted to crush soybean for convenience of soybean flaking process.
5) Soybean Flaking: It cover pressing process from the granular formation into sheet. The purpose of soybean flaking is destroy soybean tissue, create condition for steaming and roasting, make easily oil separation 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.
6) Soybean Extrusion: Soybean extrusion uses extruder to crush, flake, and change soybean into porous puffed pellets.
