Palm Kernel Pre-treatment Process

Pretreatment is necessary for efficient oil extraction from raw palm kernel.

Palm Nut Cleaning

The raw palm nut's impurity should be cleaned firstly otherwise it would cause damage to the screw press machine. The magnetic selector is installed for removing metal debris, while the vibrating sieve is used for removal of sand, fines or other undesirable impurities. And the stones could be removed by gravity stoner.

Palm Nut Shelling and Separation

Since palm kernels are encased in a hard shell, the cracking process breaks the shells, allowing the seeds to be separated for oil extraction.Specialized high-efficiency palm kernel shelling machines separate the kernels from the shells to ensure only kernels are processed.

Crushing

Since palm kernel is relatively large and hard, in order to better improve the oil yield, the palm kernel needs to be secondary crushing after husking. The main crushing equipment is rolling crusher, which can break kernels into small pieces and easy to produce oil. It has a simple structure, stable performance and easy to operate.

Flaking

Flaking machine is mainly made up of two or more opposite rotating rolls (high nickel chrome molybdenum alloy). When the kernel pieces are in the middle of the two rollers, they are squeezed by instantaneous pressure to form flakes, meanwhile, the crude oil is rolled out firstly.

Steamed cooking

The purpose of steamed cooking is to completely destroy the oil cells by high temperature and moisture, so that the protein is denatured, the oil is steamed out and collected, the viscosity and the surface tension of the oil are reduced, the elasticity and plasticity of the material are adjusted, and the enzymes are passivated. Steamed cooking equipment is a steam frying pan, which can process the raw palm kernel flakes into matured flakes by heating, spraying and steaming.

Palm Kernel Oil Pressing

Mechanical Pressing: After pre-treatment, kernels are fed into palm kernel screw press machines that apply high pressure to extract crude palm kernel oil (CPKO). Mechanical pressing can typically extract up to 45-50% of the oil content. Equipped with the automatic temperature-controlling device and crude oil filter tank, Our integrated screw oil press operates easily and has high oil output. After pressing, the crude palm kernel oil is filtered through the filter cloth and stored in tanks temporarily. The specially designed feeder ensures the feeding is continuous and average, thus the pressing process is smooth and efficient.
Heating: Some systems employ heat to improve oil extraction efficiency, making the process smoother and increasing the yield. Heating also helps reduce the oil's viscosity, easing its flow.
Continuous Pressing: In large Palm Kernel Oil production lines, continuous pressing is used to increase the amount of oil extracted. This step may also include a secondary press to further extract oil from the residual cake.

Palm Kernel Solvent Extraction Process

Palm kernel solvent extraction plant is used to extract palm kernel oil from palm kernel cake.In this part of palm kernel oil extraction plant called palm kernel oil solvent extraction, there is only less 1% oil content in the meal.

Pressed palm cake→Solvent extraction system→D.T.D.C system→Condenser system→Recovery system→Crude palm oil

Solvent extraction system

Solvent (often hexane) is used to dissolve and separate the oil remaining in the press cake. This method increases yield, especially for high-capacity plants.

D.T.D.C system

D.T.D.C means desolventizer, toaster, dryer and cooler, which is mainly used to separate the solvents from the wet meal, then the dried meal will be sent to meal silo for storage.

Miscella oil evaporation system

since miscella oil contains solvents, we need to separate the solvents from the crude palm oil by first evaporation, second evaporation and stripping tower, then we can condensate the oil and pump it into a crude oil tank, and you can choose to sell the crude oil to the refinery factory or you can set up a palm oil refinery plant by yourself.

Solvents condensing and recovery system

Usually producing one ton crude palm oil through the palm oil solvent extraction method needs around 4kg solvents. Considering of cost-effectives and environmental protection, we add this system to recycle the solvents by condensing it and collecting it for reuse.

Palm Oil Refinery Plant

We can offer turnkey palm oil refinery plant solutions from plant layout design, machinery manufacturing, onsite debugging and installing. The production capacity ranges from 5 ton/d up to 1000 ton/day

Degumming Process

The oil degumming process aims to remove the gum impurities in crude palm oil to make it suitable for further refinery processes. Water or acid is added to remove phospholipids and gums.

Deacidification Process

Oil Deacidification is a process that has a great impact on palm oil quality. If there is a problem with the neutralization process, the following decoloration will be greatly affected. The free fatty acid in crude palm oil can affect the stability and relish of palm oil.

Bleaching Process

The palm oil bleaching process is to remove oil pigment, residual soap, and metal ions. The bleaching process can improve the oil color, relish, and increase the oxidation stability, thus providing a good condition for the deodorization process.

Deodorization Process

Steam distillation removes volatile components that cause odors. The palm oil deodorization section plays an important role in improving palm oil quality. The refined palm oil is nearly colorless and transparent in the liquid state and white in the solid state.

Palm Oil Fractionation Plant (Optional)

Purpose: Fractionation separates palm kernel oil into liquid (olein) and solid (stearin) fractions. Olein is typically used in food, while stearin is used in non-food products, like soaps and cosmetics.
Dry Fractionation: This process crystallizes the oil without chemicals, followed by filtration to separate solid and liquid components. The dry fractionation method is cost-effective and ideal for high-purity olein.
Solvent Fractionation: Uses a solvent to improve the separation of olein and stearin, producing a high-quality product with higher purity.
