How to get oil from palm kernel nut?

Like most oil seeds, there are also two methods which can be used to get oil from palm kernel nut: pressing method and solvent extraction method. Which method to use is based on the daily input capacity of palm kernel nut. Generally, if the daily input capacity of palm kernel nut is more than 30 tons, using solvent extraction method  is wise, because the residual oil rate can be less than 1%. Then, what machines are used if you want to get oil from palm kernel nut? Today, I will introduce them for you one by one.

The machines used in small scale palm kernel oil pressing production line

1. Palm kernel nut cracking and separating machine

Palm kernel nut cracking and separating machine 3D picture

Palm kernel nut cracking and separating machine has two functions: one is to break the palm kernel nut, and the other is to separate palm kernel ans its shell. DOING Brand palm kernel nut cracking and separating machine can guarantee that the palm kernel is complete in cracking process and the separating rate can reach above 95%.

2. Palm kernel crushing machine

Palm kernel crushing machine

This machine is used to crush the palm kernel into small blocks, which can make the palm kernel be heated evenly in the next cooking process.

3. Drum roaster

Drum roaster for palm kernel

Drum roaster is to adjust the moisture and temperature of palm kernel blocks, and make it easier to be pressed by palm kernel oil press machine.

4. Palm kernel oil press machine

Palm kernel oil press machine

DOING Brand palm kernel oil press machine is specially designed by our engineers according to the feature of palm kernel. Because palm kernels are harder than other oil seeds, it should be more wear-resisting.

5. Plate filter

Plate filter for crude palm kernel

It is to filter the impurities from crude palm kernel oil. And then the filtered oil will be sent into crude oil storage tank.

The machines used in large scale palm kernel oil solvent extraction production line

1. Palm kernel nut cracking and separating machine

This machine is same as that of small scale palm kernel oil pressing production line. The input capacity may be larger according to customer's specific requirement.

2. Palm kernel pretreatment machines

As the above picture shows, the palm kernel pretreatment machines includes cleaning machine, crushing machine, softening machine, flaking machine, cooking machine.

3. Palm kernel oil pre-press machine

Palm kernel oil pre-press machine

Because the oil content of palm kernel is high, about 50-55%. So it need be pressed firstly, and then the cakes are sent into palm kernel oil solvent extraction plant for further processing.

4. Palm kernel oil solvent extraction plant

Solvent extraction plant for palm kernel oil

Palm kernel oil solvent extraction plant is using n-hexane to extract oil from palm kernel cakes. It consists of four systems: Solvent extraction system, D.T.D.C system, Mixed oil evaporation and stripping system and Solvent cooling and recycling system. The solvent in the palm kernel oil solvent extraction plant is recyclable, and the dry meal can be sold as animal feed. The biggest advantage is that the residual oil rate is less than 1%, avoiding oil waste.

These is the two methods of getting oil from palm kernel nut. Which method you want to use? You can send the requirement to us, and our engineers will give you suitable suggestion.
