How to refine crude palm kernel oil into edible oil, and what oils can be processed by palm kernel oil refining machine?

The equipment required to refine crude palm kernel oil into edible oil is palm kernel oil refining machine. But according to the different of processing capacity, automation level, investment budget, the palm kernel oil refining machine can be divided into batch type, semi continuous and fully continuous. Today, we mainly introduce the refining process of batch type palm kernel oil refining machine.

Small scale palm kernle oil refining machine

The detailed refining steps of crude palm kernel oil generally includes four steps: degumming, deacidification, decolorization, and deodorization．(Related reding: How does the palm oil refinery plant work?)

Refining process of palm kernel oil

Step one: Hydration degumming

Degumming is the removal of phospholipids in crude edible oil. These impurities will not only damage the stability of oil storage, but also affect subsequent refining steps, so they are removed first. Usually, we remove gumming by adding phosphoric acid and hot water.

Step two: Alkaline deacidification

Unrefined crude edible oil contains free fatty acids, which will make the oil easily rancid, so it needs to be deacidified to remove free fatty acids. In this step, we usually use add alkali (sodium hydroxide NaOH) to produce soapstock through the saponification reaction to remove acidic substances in the oil. The soapstock will also absorb other suspended impurities and remove them.

Step three: White soil adsorption decolorization

The purpose of decolorization step in small scale palm kernel oil refining plant is to remove the pigments in the oil. To achieve this goal, we usually add activated clay or activated carbon to the refined palm kernel oil. Decolorization is not only can make the oil sell in line with consumers’ preferences, but also can extend the shelf life of oil products.

Step four: High temperature distillation deodorization

The function of this step is to remove disagreeable flavor and odors that are naturally present or created during processing under high temperature. It is different from the degumming and deacidification tank, the deodorization tank is a stainless steel sealed container, including heating coil and central steam jet circulating pipe.

After these four steps, you can get high quality standard edible oil. If you are interested in obtaining high value added products, you can also buy palm kernel oil fractionation plant to make palm kernel oil olein and palm kernel oil stearin to make more money.

In addition to the above information, there is another piece of information I want to share with you that is what oils can be processed by palm kernel oil refining machine?

Palm kernel oil refining machine can also be used to refine other oils like the above photo show

In addition to refining palm kernel oil, palm kernel oil refining machine can also be used for refining other kinds of crude edible oil, includes soybean oil, peanut oil, sunflower oil, palm oil, olive oil, sesame oil, rapeseed oil, walnut oil, corn germ oil, linseed oil, castor oil, safflower oil, rice bran oil, lard oil and so on. This device really has the function of multi-use. More information about palm kernel oil refining machine and other cooking oil refining machine, welcome to contact Henan Glory Company.
