Refining of crude palm kernel oil used palm oil refining machine crude palm oil refining machine

Palm oil is through the palm fruit of fresh fruit after the crushing process palm fruit into the growth of the beam string, each about 20 to 30 kg weight contains 1500 ~ 2000 (figure 3) farmers according to the cycle of picking fruit palm fruit bouquet and must be transported to the factory processing crude palm oil quality depends on the palm fruit bouquet of intact, palm fruit once broken will be rapid deterioration, thus affecting the quality of the crude palm oil.

Palm oil and palm kernel are the main products of palm fruit crushing plant. The processing capacity is about 60~100 tons of palm fruit bundles per hour. For crude palm oil, generally through sterilization, threshing, cooking, pressing, cleaning, purification, drying and other processes.

For palm kernel, after crushing and separating, it also goes through kernel/fiber separation, kernel crushing and nucleolus separation, palm kernel drying and other processes. The dried palm kernel will be sold to palm kernel crushing plant to extract palm kernel oil.

Sterilization as the first step of palm fruit crushing is crucial to the quality of the final product palm oil. The main purposes of sterilization are as follows:Passivation of lipase activity, prevent the rising free fatty acids palm fruit is easier to fall off from the fruit of softening the skin, make it easier for oil separation nucleolus modulation, reduce subsequent nucleolar broken sterilization process is used in the process of horizontal sterilizer, about 3 bar of the steam is piped in, cooking 60 ~ 90 minutes in recent years, with the development of technology, the sterilization process also gradually developed from intermittent (figure 7) into a continuous sterilization process, improve operational efficiency, reduce labor and energy consumption

Threshing the main effect is to make the palm fruit from the fruit of out of the palm fruit of sterilization after beam will be transported into the drum thresher, as the rotation of the drum palm fruit from stem from the stem is the component does not contain any oil, so the wastage of the threshing process mainly comes from threshing still attached on the stem of the palm fruit after sterilization time is too short or too long will affect the loss of threshing, time is too short palm fruit removal;Over time, the stems absorb the resulting palm oil and are typically incinerated, leaving behind ash that can be used to make potash, biofuel or fertilizer for plantations.

Boil and Press

After threshing is brought into the digester of palm fruit, to use direct or indirect steam heating cooker is installed in the belt mixing wing center axis, palm fruit then churn, high temperature, makes the flesh soft and then stripped from the stone of the fruit mixture into crushing equipment in order to help the flow of oil, will also join a mixture of hot oil and hot water collected from clarifying tank waiting for clarification, palm kernel, fiber and other impurities from the eduction in filter cake into the preparation technology of palm kernel oil

The crushing process requires the maximum extraction of palm oil from the pulp without crushing the kernels, which can contaminate the palm oil and affect the quality. The crushing rate of nuts can be effectively reduced by using secondary or multiple pressing technology.

Purification & Plarification

The mixture in the clarifier is crude palm oil, water and a few solid particles. The traditional method of clarification is gravity separation. The mixture is heated to 85~90℃ and settled for 1~3 hours. The oil on the surface is then transferred to a centrifuge to further remove impurities from the oil, which is then dried in a vacuum. The residue from the bottom of the clarifying tank also goes into the centrifuge to recover the crude palm oil, which is eventually dried in vacuum and cooled to about 45 ° c for storage.


Crude oil contains a large number of FFA(free fatty acids), which will affect the stability and flavor of oil. FFA can be removed by adding alkali to neutralize, which is called deacidification, also known as alkali refining.


The color of crude oil is often deeper, which contains a small amount of harmful pigments after eating. Decolorization is to remove this part of the pigment, so that edible oil bright color, let people see more appetite.


After degumming, deacidification and decolorization of crude oil, there are still special odors, a small amount of free fatty acids and aldehydes and ketones, which are the decomposition products of oxidation of some oils. Deodorization can remove these odors and make the taste of cooking oil more fragrant.


Oils and fats produced by some oils are dissolved in oil with a small amount of wax. When the oil temperature decreases, it will crystallize and precipitate, making the product turbid and affecting the appearance. At the same time, waxy edible is harmful to human body. It is necessary to remove wax from crude oil.

Oil Storage Tank Station

After clarification, you will get CPO which had been removed most of solid impurities and moisture, CPO pumped into oil storage tank via oil transfer pump, Here the CPO could reach crude oil index :

1. Moisture≤0.1%

2. Impurities≤0.02%

3. Acid value≤5%.

Depericarping Station

1. You get fiber nut mixture after pressing the fruit, the mixture will go into pneumatic fiber transport system through cake breaker conveyor for fiber nut separation.

2. The fiber will be transported to Boiler station for heating fuel through depericarper column ducting and fiber cyclone.

3. The nuts will be polished by Nut Polishing Drum,then come into nut destoners column via auger conveyor.

Kernel Recovery Station

1. Nut conveyed into nut silo after grading,then stored in nut hopper temporarily.

2. When nut accumulate to a certain amount they will be crushed into shell kernel mixture by nut ripple mill, then go into Cracked Mixture Separating System through Cracked Mixture Conveyor, Cracked Mixture Elevator for two stage air separation, non-separation shell kernel mixture will be separated by CLAYBATH. Wet kernel density is 1.07,wet shell density is 1.17,and the clay density is 1.12, so wet shell sink to the bottom then enter into Shell Hopper via shell elevator and shell conveyor.

3. The separated wet kernel contain moisture 25-30%, it will be conveyed with air separated kernel into kernel silo for drying and dehydration through Wet Kernel Elevator, Wet Kernel Conveyor and Wet Kernel Distributing Conveyor. After drying to less than 7% moisture content, then transport by Dried Kernel Conveyor, Dried Kernel Elevator and Dried Kernel Distributing Conveyor. Finally arrive Kernel Storage SILO for storage.

4. Dehydrated kernel could use for palm kernel oil extraction, or for sale.

All the separated fiber and shell will be transferred to Boiler station for heating fuel through Fiber Shell Conveyor.

Palm mill Waste Water

The plant will produce about 0.65 tons of waste water for every 1 ton of palm fruit bunches. These wastewater will affect the environment due to its high acid value, high BOD value and high COD value. Generally, anaerobic or aerobic reactions in treatment pools can bring BOD to less than 100mg/L. In areas with stricter environmental requirements, more advanced processes will be used to treat the sewage.
