The process of crude red palm oil to RBD palm oil(cooking oil) contains four steps: degumming, deacidification, bleaching and deodorization. Next, i will introduce it to you in detail.
Palm oil refining process(From red palm oil to RBD palm oil)
In degumming step of refining palm oil, it generally adds phosphoric acid to remove the gum out. The function of phosphoric acid is to convert colloidal substance into water-soluble substance.
In small scale palm oil refinery plant, the water-soluble substance will absorb other impurities and become larger and larger. At last, these impurities will sink and be discharged out. And in large scale palm oil refinery plant, these impurities will be absorbed by bleaching earth in bleaching process together with pigment.
There are two kinds of deacidification methods can be selected in deacidication process of palm oil refining process, they are: chemical refining and physical refining. But in small scale palm oil refinery plant, we often uses chemical deacidification method. Adding alkali liquor can neutralize the free fatty acid in crude palm oil, then the soap stock will be generated and be discharged out. In large scale palm oil refinery plant, it uses distillation method(physical refining method)to steam the free fatty acid out.
In bleaching process of palm oil refining machine, the crude palm oil is mixed with bleaching earth in vacuum condition to absorb impurities and colour pigments in refined palm oil.
In deodorization process of palm oil refining process, we usually remove the odors by injecting the high temperature steam.
