What are the features of physical refining and chemical refining?

According to different edible oil refining technologies, we generally classify it into Physical Refining & Chemical Refining.

edible oil reifning methods

Physical edible oil refining process and chemical edible oil reifning process

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 Machine:
1.High refinement rate; less oil loss.
2.No waste water discharged.
3.More FFA distilled.
4.Especially suited for highly acidic oils, and those of low gum content

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

Features of Chemical Refining Machine
1.Excellent adaptability and fewer requirements for high oil quality
2.The finished oil is consistent and stable
3.Less bleaching earth necessary compared with physical refining
