The extraction of peanut oil is a complicated process. In general, peanut oil production line includes three sections: peanut oil pretreatment and pressing section, peanut oil solvent extraction section and peanut oil refining section. Today, I will mainly introduce the first section --peanut oil pretreatment and pressing section.

Pretreatment and pressing section is the basic part of the peanut oil plant, which includes a series of steps such as cleaning, husking, crushing, softening, flaking, cooking and pressing. Its purpose is to remove various impurities in the peanuts, adjust the moisture and temperature of the peanuts, and improve the internal structural state of the peanuts for the extraction of edible oil in the pressing stage.
