Edible oil solvent extraction line

Edible Oil Solvent Extraction Process Introduction

Edible oil solvent extraction line extracts oil and fat by leveraging the mutual solubility between lipids and organic solvents. This technology applies to all oil-bearing raw materials, including prepressed oil cakes from peanuts, rapeseeds, sunflower seeds and cottonseeds, as well as extruded materials such as soybeans and rice bran.

After raw materials are fed into the extractor, organic solvents fully contact oilseed flakes to dissolve and extract the contained lipids. This process reduces residual oil in the final meal to less than 1%. Afterwards, solvents are separated and recovered from the mixed oil via heating and vaporization for recycling within the production line.

Compared with mechanical oil pressing, solvent extraction boasts prominent strengths. First, it achieves extremely low residual oil in meal and maximizes the overall oil yield of the whole processing line. Second, it produces high-quality oilseed meal widely used as high-grade raw material for the feed industry. In addition, the finished crude oil features minimal solvent residue after desolventizing, meeting food safety standards.
