Crude Palm Oil (CPO) is mainly further processed into edible oil for food purpose. To meet the international industry’s standards for edible oil, the crude palm oil produced by palm oil mills should be refined in palm oil refinery plant. Palm oil refinery process mainly includes palm oil degumming, palm oil deacidification, palm oil bleaching and palm oil deodorization.

Palm oil refinery process flow chart How to refine crude palm oil to refined oil?

The refining process removes water, odouriferous matter, phosphatides, free fatty acids and other impurities including dirt and traces of metals from palm oil mill. After processed in palm oil refinery plant, the final oil product is a kind of premium edible oil of consistent quality which not only satisfies customer requirements and industry’s standards in respect of Iodine Value, FFA, flavor, color, melting point, peroxide value, impurities and moisture.

Basic Steps of palm oil refinery plant:

The first step is degumming

In degumming process, remove the gelatinous substances such as phospholipids and proteins in the crude edible oil to obtain degummed edible oil.

The second step is deacidification

The acidic substance not only affects the taste of the vegetable oil, but also affects the quality of the vegetable oil. What's more, according to edible oil standards, the acid price index is one of the most important indicators for measuring the quality of edible oil.(Acid value shall not be more than 0.5)

The third step is decolorization

Decolorization process is with the adsorption of white clay to remove the dark color in crude vegetable oil, then make the oil clear appearance, light color.

The last step is deodorization

In the deodorization process, with high temperature evaporation principle, the vegetable oil is heated to above 230 ° C, to reduce the peroxide value of the vegetable oil, at the same time, a small amount of pigment and free fatty acid are also able to be removed. Deodorization can make sure the quality of the reined vegetable oil, which is also an important steps of making refined vegetable oil.

Physical Refinery Vs Chemical Refinery

Chemical refining and physcial refining of palm oil

Crude palm oil can be processed by either physical refining (distillative neutralization, steam stripping) or chemical refining (alkaline refining) to produce RBDPO and NBDPO. RBDPO refers to refined, bleached and deodourised palm oil, while NBDPO refiers to neutralised, bleached and deodourised palm oil.

What is physical refining of palm oil?

Physical refining is also known as steam refining. In degumming process, it utilizes citric acid or food grade phosphoric acid to remove natural gums in the form of phosphatides. Then, in bleaching process, under vacuum, Fuller’s Earth is used to remove colouring matters and adsorb any metal ions. The deacidification and deodorization process is under high temperature and low pressure. By used of live steam, the FFA is stripped of. The steam is then recovered together with the entrained oil is as palm fatty acid distillate. The off-flavors and odours can also be removed from the crude palm oil in the steam distillation process.

Physical palm oil refinery process is the most common used type in palm oil processing industry. It is featured of low production cost, high efficiency, simple production process and low effluent load.

What is chemical refining of palm oil?

Chemical refining of palm oil is the traditional method used in past centuries. The main purpose of chemical refining is to remove the FFA by an alkaline solution and at the same time remove other impurities.This chemical refining of palm oil can be used for refining almost all crude vegetable oils, such as soyben oil, peannut oil, cottonseed oil, rapeseed oil, sunflower oil, palm kernel oil and so on.

The factors that influence the deacidification in palm oil chemical refining process:

1.The types and amounts of alkali;

2.The lye concentration;

3.Operating temperature;

4.Operating time;

5.Operating of mixing and stirring;

6.The influence of impurities;

7.Operating of oil soap separation;

8.Operating of washing and drying.
