palm oil refining machinery introduction:
Refining is a process to remove unwanted and undesirable elements from the crude edible oil.palm oil refining machinery usually includes the following sections: Degumming,Deacidification, Decolorization,Deodorization and Dewaxing. 

Our palm oil refining machinery adopts the most advanced CE and ISO9001 approval edible oil refining line to get high purity and high oil yield refined  oil. Available with both physical and chemical refinery technology, we are able to provide customers the most affordable palm oil refining machinery including design, manufacturing, installation with guaranteed quality and reliable service.

Degumming process of palm oil refining machinery:
Intermittent process preheats crude oil to 80 ~ 85 ℃. The amount of water in crude oil bases on colloid content, and generally 3-5 times of the gum content, water temperature at 85 ~ 90 ℃ (5 ℃ higher than oil temperature). Finish water adding in 40-60min, along with 60-70r/min stirring, continue stirring 3-5min after adding water, and stand for precipitation 2-4h.

Deacidification process of palm oil refining machinery:
The crude oil is pumped to Deacidification from oil mill or storage tank & first it is treated with weak solution of phosphoric acid or other suitable degumming agent for removing gums. Deacidification is used remove the Free Fatty Acids (FFA) by adding caustic soda. Oil is heated up to about 60°C by heating coils and oil is stirred by the stirrer. The chemical reaction between free fatty acid and caustic soda forms the soap stock. This soap stock is allowed to settle down in the neutralizer from where it is collected into the soap pans. The oil is then washed with hot water to remove traces of soap particles and free alkali. 


Decolorization process of palm oil refining machinery:
Degumming of cooking oil can remove grease in oil pigment to improve oil color, adsorption of aflatoxin and trace metals, phospholipids, other gum and other impurities. It ensures high quality of cooking oil and improves oil stability.

Deodorization process of palm oil refining machinery.
Control oil temperature to 250 ~ 270 ℃ when decolorized edible oil enters into deodorizer, in direct steam injection, the free fatty acids, ketones, aldehydes and other impurities are removed from the oil, the thermal decolorized action also occurs, and the pigment composition is cleaved distilled from the oil. Deodorized vacuum (absolute pressure) controlled at 266 Pa, the deodorization time is about 2h.


De-waxing Process of palm oil refining machinery:
Dewaxing process is carried out for cooking oil,Sunflower oil and Rice Bran Oil as they contain waxes compared to other oil. This wax is removed by the dewaxing process. The oils are subjected to winterization process. The oil is first processed in the crystallizer where it is cooled by chilled water circulation. Low temperature results in the formation of crystals which are removed in the filtration process.


Available capacity for palm oil refining machinery are as follows:
1-2-3-5-10TPD batch cooking oil refinery machine;
10-15-20-25-30-50TPD semi continuous cooking oil refinery machine;
