How to Get Edible Oil from Palm Oil Refining Machine

Palm oil is the second largest edible vegetable oil in the world. As the result of low cost in both palm tree planting and low oil price, palm oil as edible oil has obvious competitive advantages on world’s market. Palm oil after physical oil pressing process is only crude oil, which needs a series of palm oil refining process in order to achieve edible oil standard.

The purpose of palm oil refining machine is to remove impurities in order to reach edible oil standard. Palm oil refining machine covers a series of processes including crude palm oil, degumming, decolorization, deodorization and fractionation. The complete processing line of palm oil refinery contains hydration degumming, alkaline neutralization, steam distillation deacidification, active carbon absorbent activated clay or high temperature vacuum deodorization while removing low boiling volatiles.

What is major process of crude palm oil refining machine processing line?

Crude palm oil filtration
The crude palm oil should be filtrated in order to remove suspended particle impurities and other impurity for further step palm oil processing.

Degumming
Crude palm oil degumming removes impurities of phospholipid, sugar, protein mixture, trace metals and other impurities. The quality of raw material oil greatly determines the quality of the final product. The gum in raw material crude palm oil is an important factor in the quality of grease.
The advanced degumming technology can remove gum completely in crude palm oil. The centrifugal separator can make the best degumming result in order to obtain the highest quality refined palm oil.

Neutralization
Neutralization deacidification is playing extremely important part in palm oil quality and price. Both physical and chemical methods are available to make high efficiency deacidification. Physical palm oil refining machine adopts stripping distillation method as preferred palm oil refining process. Chemical palm oil refining refers to neutralization with sodium hydroxide and free acid in crude oil deacidification to produce soap and water.

Decolorization
Decolorization can remove pigment in oil, but also serve to reduce the phospholipid content, peroxide value, and the role of the amount of soap containing metal ion content, thereby improving oil color, flavor and oxidative stability of hydrogenated oil further oil refining, deodorization.

Deodorization
In the deodorization process, in addition to complete deodorizing purposes, palm oil refining machine process should focus more on the current unit operation strive to achieve at a low temperature, short time, preventing the generation of trans fatty acids, tocopherols to reduce the loss, reduce the polymerization and reduce the vitamins decomposition.

The palm fruit oil after fractionation can obtain vegetable palm oil with high edible oil standard. We have rich experience of palm oil processing machines from palm oil press, crude palm oil refining and palm oil fractionation with mature technology of design, manufacture and installation. The palm oil refining machine has just help users to get the highest quality palm oil at affordable price.
