Similar to other conventional oil seeds extraction methods, palm kernel oil can be extracted with three methods, including mechanical pressing method, solvent extraction method and pre-pressing & solvent extraction method, and these three extraction methods have their own features.
Method 1: Mechanical pressing method
Mechanical pressing method is to produce palm kernel oil by using pure physical pressing process. The entire production process includes cleaning, crushing, cooking, pressing and crude palm kernel oil filtering.

This extraction method does not involve the addition of chemical substances, retains the rich nutrients in the oil, is free of chemical solvent pollution, and does not contain other chemical preservatives and antioxidants. However, the disadvantage of producing palm kernel oil by the mechanical pressing method is the low oil yield.
Method 2: Solvent extraction method
Solvent extraction method is also called leaching method, It uses the N-hexane to extract oil from the processed palm kernel cake, the whole working process includes four parts: oil extraction, miscella oil evaporative stripping, wet meal desolvation and solvent condensation recovery. After palm kernel oil solvent extraction process, the oil residue rate in meal will be less than 1%.

Solvent extraction method is usually the best choice for large scale 怕palm kernel oil mill plant, because it has the features of high oil yield.
Method 3: Pre-Pressing & Solvent Extraction method
In order to further increase the extraction efficiency of palm kernel oil, people can also combine the mechanical pressing method and the leaching method. With these two combined extraction methods, the vast majority of the oil can be extracted from the palm kernel, thus maximizing the efficiency of the entire palm kernel oil production and reducing the production cost.
Palm kernel oil pre-pressing & solvent extraction method
No matter which extraction methods you use to produce palm kernel oil, high-quality palm kernel oil processing equipment is an important factor to ensure your successful production.
