Small Scale Palm Oil Refining: A Starter's Guide to Essential Equipment & Process

Crude palm oil is a raw commodity, but its refined version—with improved color, neutral odor, and superior quality—commands higher profits and broader market access. For newcomers entering this lucrative field, a small scale palm oil refining mill represents the perfect entry point. Yet, the key to success lies in understanding not just the “why,” but the “how”: what equipment is needed and how it transforms crude oil into a premium product.

Essential Equipment in a Compact Palm Oil Refining Mill
A typical small-scale setup utilizes a batch processing system, which is cost-effective and flexible for varying production volumes. The essential equipment lineup forms a complete processing circuit:

Heart of the Process: Three core tanks: the refining tank (for degumming and deacidification), the decolorization tank (for bleaching), and the deodorization tank (for final purification).

Critical Support Systems: A steam generator provides the necessary steam and vacuum, while a filtration system (like a plate filter) removes spent bleaching agents and impurities.

The Heating Decision: The main system variation lies in the heating method. You can opt for an electric heating system integrated into the tanks, or a thermal oil heating system. The latter uses a dedicated thermal oil heater to circulate hot oil, offering more uniform and efficient heat transfer for slightly larger or more consistent operations.

The Five-Step Palm Oil Refining Process
Regardless of the heating choice, the process follows a proven chemical and physical pathway to purity:

Degumming: In the refining tank, phosphoric acid and water are added to convert and hydrate gums, allowing them to be separated.

Deacidification: An alkali is introduced to neutralize free fatty acids, forming soapstock which is then removed.

Decolorization: The oil is heated and mixed with bleaching earth, which adsorbs pigments and unwanted color bodies.

Filtration: The oil-clay mixture is pumped through a filter, separating the clean oil from the used adsorbent solids.

Deodorization: Under high temperature and a strong vacuum, volatile odor compounds and remaining moisture are stripped away, yielding stable, tasteless, and odorless refined palm oil.

How can I purify crude palm oil? What is the purification process?

 

High quality standard palm oil is now more competitive in the market. Therefore, more and more palm oil processing plants will use palm oil refining machine to remove the impurities out of crude palm oil to achieve the purpose of purification. The crude palm oil purification process mainly includes the following four steps: degumming, deacidification, decolorization, deodorization.

Crude palm oil purification process

Degumming is the first step to purify crude palm oil. Generally speaking, the colloidal impurities in crude palm oil can be removed by physical or chemical methods.

Deacidification is the second step to purify crude palm oil. Crude palm oil contains free fatty acids, which will affect the stability and flavor of palm oil to a certain extent, and can be removed by alkali neutralization.

Decolorization is the third step to purify crude palm oil. Crude palm oil contains chlorophyll, carotenoids and other pigments, which affect the stability and appearance of the final palm oil, so white clay is often used to absorb pigments and other impurities in palm oil, lighten the color and increase the value of the oil.

Deodorization is the fourth step to purify crude palm oil. Water vapor is commonly used to deodorize palm oil. The deodorization time and temperature of this section must be strictly controlled, which is beneficial to inhibit the production of trans fatty acids, reduce the loss of tocopherol, reduce polymerization, and reduce vitamin breakdown.
