Converting Crude Oil into Premium Edible Products
Crude vegetable oils contain impurities including phospholipids, free fatty acids, pigments and waxes that must be removed to meet food-grade standards. Huatai refining systems deliver crystal-clear, stable oils ready for bottling.
Degumming & Neutralization
Hydration degumming removes hydratable phospholipids while enzymatic degumming targets non-hydratable phospholipids. Alkali neutralization (chemical refining) or steam distillation (physical refining) then removes free fatty acids to achieve acid values below 0.2 mg KOH/g.
Decolorization (Bleaching)
Activated clay adsorption under vacuum removes carotenoids, chlorophyll, soaps and trace metals from neutralized oil. Our continuous bleaching systems operate under precisely controlled temperature and vacuum to minimize oil loss and clay consumption while achieving consistent color removal.
Dewaxing & Winterization
Low-temperature crystallization followed by filtration removes high-melting waxes from oils like sunflower, corn and rice bran. This winterization process ensures the refined oil remains clear and free of cloudiness even under refrigeration conditions, meeting premium retail standards.
