Oil refining is according to the different usage and requirements, utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.
The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction, will be pumped into oil refinery units to produce cooking oil at various grades.
These processes include neutralization (removing free fatty acid), degumming, decolorization(bleaching), deodorization.Then you can get first grade oil.
Main parts: Refining pot, Decoloration pot, Deodorization pot, Oil pumps and other parts.
