Crude oil refining is an important part of edible oil manufacturing. Oil refining machine can remove mechanical impurities, solute impurities, pigments, moisture, and free fatty acids in grease. Our oil refining machine is suitable to all kinds of oil, eg: rice bran, palm, sunflower, soybean, sesame, rapeseed, peanut, cotton seed, corn germ, walnut, almond, castor seed etc.
● Degumming
- Removes phospholipids (gums) from crude soybean oil using water or acid.
- Output: Degummed oil and lecithin (by-product).
● Neutralization (Alkali Refining)
- Treats degummed oil with an alkali (e.g., NaOH) to remove free fatty acids (FFAs).
- Output: Neutralized oil and soapstock (by-product).
● Bleaching
- Uses bleaching earth or activated carbon to remove pigments, oxidation products, and residual impurities.
- Output: Bleached oil.
● Deodorization
- Steam distillation under high temperature and vacuum removes volatile compounds, odors, and flavors.
- Output: Refined, deodorized soybean oil.
● Improvement of grease quality
● Increase the added value of products
● Energy efficiency and health
