In edible oil refinery plant, there are four steps to refine palm kernel oil: degumming, deacidification, decolorization and deodorization. The following is the palm kernel oil refining process flow chart which shows the palm kernel oil chemical refining process:
November 14, 2019 by vegetable oil refinery
To refine crude palm oil into RBD palm oil generally uses the physical refining process, which is preferred over the chemical refining process. Because high acidity (up to 5%) can lead to excessive loss of neutral oil in the soapstock after alkali neutralization. And ususally the crude palm oil has high content of free fatty acid, using physical refining process can better remove the free fatty acid from crude oil. [Related reading: How to remove free fatty acids from crude palm oil?]
Palm oil physical refining process flow chart
The palm oil physical refining process flow chart is as the above picture shows. It includes degumming, decolorization, deacidification and deodorization four processes.
The degumming process of crude palm oil:
To remove the gums from crude palm oil, it usually uses dry degumming process because the gum percentage of palm oil is very less. The first step is heating the crude palm oil into 60-70 ℃, and then mixed the phosphoric acid with palm oil in the phosphoric acid reaction tank. The few gums will be absorbed by white clay in deacidification process.
The degumming machine in palm oil refinery plant
The decolorization process of crude palm oil:
During decolorization process, the required temperature of oil is 100-110℃. The oil after heating will be mixed with the white clay in white clay mixture tank, and then go into the decolorization tower. There are plenty of small holes on the cover of white clay, which will adsorb the color of the palm oil. At last, separate the waste white clay by leaf filter.
The decolorization machine in palm oil refinery plant
The deacidification and deodorization of crude palm oil:
Deacidification process and deodorization process are both in deodorization tower. On the top of tower is deacidification section, and on the bottom of tower is deodorization section. As the following picture shows.
The deodorization tower in palm oil refinery plant
Under the vacuum and high temperature the FFA(free fatty acid) and bad smell will be taken out. Because the required temperature of deodorization process is very high, about 260℃, the palm oil must be deoxidized to remove the oxygen in advance to avoid the palm oil oxidation and go bad.

How to choose suitable machines to making groundnut oil? It depends on how many tons groundnut you want to process per day. Next, I will introduce for you briefly.
1.Less than 10 tons per day
Because this input capacity is small, usually we advise you to buy an integrated groundnut oil press machine and a roaster to adjust the temperature of groundnut before pressing.
2.10 – 30 tons per day
If the input capacity is 10–30 tons per day, the groundnut oil pressing line is suitable for you. You need buy the groundnut pretreatment machines and groundnut oil press machines.
3. Above 30 tons per day
When the iput capacity is more than 30 tons per day, the solvent extraction technology is most suitable, because the residual oil rate can be less than 1%. You should buy the groundnut pretreatment machines and oil solvent extarction machines.
If you want to get refined groundnut oil, you need buy groundnut oil refining machine together. It has three types: batch type, semi-continuous and full-continuous type.
