Palm oil refining classification:

Palm oil classification is divided into two kinds, physical refining and chemical refining.

Physical refining means removing gum in palm oil during process of degumming in special method and removing FFA in process of deodorizing by steam. 

Chemical refining, however, means removing FFA in a chemical way ( Acid-base neutralization). Gum and soap foot produced is separated by centrifuges.

1.The finished oil is consistent and stable.

2.Excellent adaptability and less requirement to oil quality.

3.Less bleaching earth is added into compared with physical refining.

Palm oil refining - Physical Refining:

1.High oil refining rate, less oil loss.

2.No waste water discharged.

3.Especially suitable for oils of high acid value, and low gum content.

4.More FFA distilled out.
