Efficient Peanut Oil Extraction: Advanced Techniques and Equipment

Peanuts are high in oil content and are commonly used for edible oil production. In industrial production, most oil factories use physical pressing techniques to produce peanut oil, which is preferred by consumers. The traditional pressing method relies on physical force to squeeze out crude oil, which is green and healthy. However, the pressing method cannot fully extract oil from the cake, leaving residual oil in the pressed peanuts and cake. This residual oil affects the quality of peanut cake and wastes oil resources for the factory. Therefore, large edible oil processing plants can use the pre-pressing and solvent extraction process to fully utilize the residual oil in the cake.

The solvent extraction method for producing peanut oil involves fully soaking or spraying peanut cake with a chemical solvent to obtain a miscella oil solution. Subsequent processes such as evaporation, condensation, and recovery separate and recover the solvent. Refining equipment then removes solvent residues and impurities, and through steps like deacidification, degumming, decolorization, and deodorization, the oil meets the required edible standards.

The quality of peanut oil extracted from peanut cake differs from that extracted directly from peanuts. Different quality equipment yields varying quantities and qualities of peanut oil. To fully extract oil from peanuts, one needs high-quality mechanical equipment and experienced manufacturers with mature processes. Good peanut oil extraction equipment can significantly improve both the oil quality and yield.

Huatai Group's peanut oil extraction equipment is customized according to client requirements, saving significant costs in the process. The equipment plans and technology upgrades ensure the lowest residual oil and solvent in the meal, achieving optimal production operation.
