Physical refining method need remove of FFA (free fatty acids) occurs during deodorizing process of physical refining process. Its refining process is degumming, decolorization, deacidification and deodorization.

Procedure one: Degumming

Add food grade phosphoric acid to the crude palm oil to transform the non hydrated phospholipid into hydrated phospholipid, and add water to make the gum enter the aqueous phase to precipitate and remove.

Procedure two: Deacidification

Degummed palm oil is added with food grade alkaline for acid-base neutralization reaction and removed by heating and natural sedimentation.

Procedure three: Decolorization

When the palm oil is heated to a certain temperature, a certain amount of activated clay and activated carbon are added in the neutralized palm oil, the pigment in the palm oil will be physically adsorbed, so as to achieve the purpose of decolorization.

Procedure four: Deodorization

The deodorized palm oil is heated to high temperature (250-260 ℃) and then enters into the deodorization tank. Under the negative pressure, a small amount of overheated steam is introduced into the palm oil for stripping for a period of time, so as to achieve the purpose of deodorization.
