Palm oil processing mill palm oil production process palm kernel oil processing

Raw palm oil (CPO) and palm meal (PE) can be obtained from palm pulp through the process of boiling and crushing.At the same time, during the crushing process, palm fruit (palm kernel) is separated, then crushed and removed from the shell, and the remaining kernel is extracted to produce crude palm kernel oil (CPKO) and palm kernel meal (PKE) oil palm fruit contains two different oils, palm oil from pulp;Palm kernel oil is obtained from palm seed (kernel), of which the former is more important. All these products have been effectively applied in food, chemical industry, agriculture and other fields. It can be said that palm is a good economic plant

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.


The sol-soluble impurities in crude oil include phospholipids, proteins, carbohydrates and so on, mainly are phospholipids. The usual degumming methods are hydration degumming and acid refining degumming. The purpose of these two methods is to remove phospholipids of different properties and remove as many colloidal impurities as possible from crude oil.


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.

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.
