Solvent Extraction Method for Edible Oil Processing

Put simply, the high oil content makes it difficult to adequately flake the oilseed and cook it for solvent extraction without oil coming free of the seed and fouling equipment. Furthermore, the 40% oil content would require much more than the optimum energy for removal of solvent from miscella in extraction. Therefore, the screw press technology is used before extraction to better prepare the
