Palm oil mill process is quite different from other oil seeds processing. Palm oil mill process includes 6 parts: Palm fruits receiving, sterilizing, threshing, digesting and pressing, crude oil clarifying and palm kernel recovery.Our palm oil mill process is low cost and energe-saving.

Palm oil is extracted from fresh fruit bunches (FFB) by a mechanical process, where a palm oil mill plant commonly handles 60-100tph of FFB.

A typical palm oil mill has many operational units as shown in Figure 2. This comprises of sterilization, threhsing, digesting and pressing, clarification, purification, drying and storage. For the palm kernel oil production line, there are steps such as nut/fiber separation, nut conditioning and cracking, cracked mixture separation, and kernel drying and storage. The dried kernels are often sold to palm kernel crushers for extraction of crude palm kernel oil. In some integrated plants, kernel crushing facilities exist side by side in the same complex.

Production capacity: 60-120TPH

Work flow of palm oil mill process:

Palm oil mill process flow chart as follows:

Large-scale palm oil mill plants, featuring all stages required to produce palm oil to international standards, are generally handling from 60 to 120 tonnes of FFB/hr. The large installations have mechanical handling systems (bucket and screw conveyers, pumps and pipelines) and operate continuously, depending on the availability of FFB. Flow chart of the palm oil mill process is shown as follows:

1.Raw material reception:

As for the first step of palm oil mill process,collecting the FFB and convey by trucks, then pour the fluster into the discharge door after weighed.

FFB are airtight sterilized in sterilizer of palm oil mill process,  the purpose is to prevent enzymes broken down, avoiding FFA content in oil further increase.

The purpose of threshing in the palm oil mill process is to separate the palm fruit from the FFB. The drum type thresher is the usual machine to separate the fruit.

4.Digesting and pressing:

The purpose of digesting in the palm oil mill process is to separate the pulp and nut and crush the palm pulp.  Then it is sent to continuous screw press. After pressing of palm oil mill process, oil palm fruit is divided into two parts: the mixture of oil, water and solid impurities, and the press cake (fiber and nut).

5.Oil clarification:

As for the oil clarification of palm oil mill process,oil is clarified by the vibrate screen.

6.Kernel recovery:

As for the last step of palm oil mill process, The separated fiber material is sent to the boiler room as fuel; the separated kernel is transported to kernel warehouse by pneumatic conveying system for temporary storage.

We will choose the palm oil mill process according to the different requirements of different customers. Both technical and economic effects are taken into account while plan the palm oil mill process, so that to build the best palm oil mill plant, Henan Doing Company is your best choice. After processed through the palm oil mill process,the crude palm oil can be sold or deeply processed. The next station of palm oil mill process is palm oil refinery process:

Palm oil refinery is an essential process for a complete palm oil mill plant because there are still some impurities such as phospholipids, FFA, pigment, odor,etc. in the crude palm oil. Henan Doing Mechanical Equipment Co.,Ltd, as a professional palm oil refinery manufacturer who is devoted to processing pure edible oil for worldwide customers. We can provide professional technical support and first class palm oil refinery plant and other palm oil machine for customers.

In general, palm oil refinery plant devides to 3 types: batch palm oil refinery plant, semi-continuous palm oil refinery plant, continuous plam oil refinery plant. These 3 oil refinery plants are used for different capacity. But the processes in each oil refinery plant are almost the same.

Main Steps of palm oil refinery:


In this step gums in crude oil are removed by hydration with the help of phosphoric acid. Degumming is the first step for the whole palm oil refinery process.


In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.Neutralization is also called deacidification, it is the important part for palm oil refinery.

3. Bleaching

  During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer. Bleaching is also decolorization in palm oil refinery.

4. Deodorization

Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure. Deodorization is mainly for making oil color lighter during palm oil refinery process. Which can make oil looks good.
