Palm oil is the most widely consumed vegetable oil on the planet. The oil rate in oil palm is very high: generally 46~50% in the fresh pulp , and 50~55% in palm kernel. And oil palm can produce two kind of oils – palm oil extracted from fresh fruit and palm kernel oil obtained from the nuts. Both palm oil and palm kernel oil are widely used in various industries, including food, chemical and others.

In order to ensure smooth palm oil production and palm kernel oil production, there are several things that you must make it clear, how to extract palm oil? How to extract palm kernel oil? And the basic equipments involving in palm oil production process, palm kernel oil production process.

What is palm oil?

Palm oil is the most widely-used vegetable oil in the world which is used as a raw material for both food and non-food industries. Palm fruit oil, generally known as palm oil, is produced from the pulp of the fruit of the oil palm tree. Palm oil can be used both as a crude oil as well as in the refined form.

What is palm kernel oil?

Palm kernel oil, which is extracted from the palm nut, or kernel, of a species of African palm tree. Palm kernel oil is commonly used in commercial cooking because it is lower in cost than other oils and remains stable at high cooking temperatures. The oil can also be stored longer than other vegetable oils.

How to extract palm oil from palm fruit?

Palm oil is extracted from fresh fruit bunches (FFB) by mechanical process.The palm oil production process for large scale is complexed.

Below you may find steps,how palm oil is extracted from palm fruit:

First, the palm fruits go through a process known as sterilizing. Using high temperature to cook palm fruit bunches which can easily separate palm fruit.

Next, the palm fruits go through a process known as threshing, in which each piece of fruit is separated from the rest of the bunch.

After threshing, the next step in palm oil production involves digesting the palm fruit into palm pulp. This is followed by pressing, in palm oil  pressing process, the most widely used palm oil machine is screw palm oil press machine.

After the above processes, we can get crude palm oil. In order to getter high quality palm oil, the palm oil clarification process is necessary.

How to extract palm kernel oil from palm kernel?

As we all know, oil palm is a kind of important tropic oil seed plant. Rate of oil in oil palm is very high. Common fresh fruit flesh: 46%-50%, palm kernel: 50%-55%.

The process of processing palm kernel is as following:

1.First, we should polishing palm nut, because palm nut contains much fiber.

2.Then, we can use palm kernel cracking and separating machine to crush palm nut and separate palm kernel and shell

3.After cracking and separating, we need to cook palm kernel which can adjust moisture and temperature.

4.Pressing section, pressing palm kernel and get crude palm kernel.

Why do the palm oil need to refine?

After palm oil processing process and palm kernel oil processing process, we get crude palm oil andf crude palm kernel oil. However, the crude edible oil can’t eat and sell to the market. The crude edible oil must be processed with palm  oil refinery plant. After refining, the flavor, color and smell of edible oil is improved, the stability is improved which is good for long time storage, the smoke point of oil is increased.

What kinds of edible oil can be refined by edible oil refinery plant?

Palm oil refinery plant can process corn germ oil,soybean oil,peanut oil,rapeseed oil,cottonseed oil,rice bran oil,sunflower oil,palm oil,palm kernel oil,etc.

Palm oil refinery plant process:

Palm oil refinery is based on the different usage and requirements, utilizing the physical methods and chemical methods to get rid of the harmful impurities and needless substance in the crude palm oil, getting standard palm oil.

Major process during palm oil refining process:

Crude palm oil→Degumming process → Deacidification process → Decolorization process → Deodorization process → RBD palm oil

We have three kinds of palm/ palm kernel oil refining machine can be choosed:
Batch type palm oil refining machine suitable for small capacity like 1-2-3-5-10tpd;
Semi-continuous palm oil refining machine suitable for medium capacity like 10-30tpd;
Full-continuous palm oil refining machine suitable for bigger capacity over 30tpd.

Palm oil fractionation is to separate palm oil into low melting point liquid phase (soft fat also named palm olein) and high melting point solid phase (palm stearin) by control the cooling and crystallizing process. It can greatly maximize the value of products
