Flowchart of Oil Refining
Edible Oil Refining / Vegetable Oil Refining
According to different edible oil refining technologies, we generally classify it into Physical Refining & Chemical Refining.Edible Oil Refining - Physical Refining
Physical refining means removing gum in oil during process of degumming in special method and removing FFA in process of deodorizing by steam.
Features of Physical Refining
- Less oil loss and higher edible / vegetable oil refining ratio.
- No waste water in the edible oil refing process of production.
- More FFA is distilled out.
-
More suitable for oil with high acid value and low gum impurity.
Edible Oil Refining - Chemical Refining
Chemical refining, however, usually means removing FFA in a chemical way ( Acid-base neutralization). Gum and soap foot produced is separated by centrifuges. It is one popular refining method of edible / vegetable oil refining.
Features of Chemical Refining
- Excellent adaptability and less requirement to oil quality.
- The finished oil is consistent and stable.
- Less bleaching earth is added into compared with physical refining.
Chemical Refining usually includes the following sections:Hydration Degumming, Versatile Neutralization Washing, Bleaching, Deodorizing, Dewaxing.
