The common method of extracting palm oil is pressing. The picked palm fruits are pressed and sterilized to extract the palm oil.

The acid value of pressed crude palm oil is high and contains a large amount of free fatty acids, which will affect the storage and quality of palm oil. It needs to be refined and separated by palm oil refining equipment. Palm oil refining separates impurities through degumming, alkali refining, washing, drying, decolorization, and deodorization.

1) Degumming is to separate phospholipids, proteins and other colloid-soluble impurities.

2) Alkali refining is to neutralize and separate free fatty acids in crude oil and adsorb impurities such as pigments.

3) Washing is to wash away residual soap in alkali-refined oil. Then dry and vacuum remove moisture from crude oil.

4) Use activated white clay for decolorization to adsorb pigments, trace metals, residual soap, etc. in crude oil.

5) Then deodorize, and remove free fatty acids, pigments, volatile substances, etc. by vacuum distillation.
