Palm Nut Pretreatment
Palm kernel pre-treatment is indispensable to get pure palm kernel oil; more important, the clean palm kernel is favor to protect oil press and extend its working life. 

a.Vibrating screen is used here to sieve sand, stones and other debris; at the same time, magnetic separators are adopted to separate metal debris.
b. A hammer grinder is necessary to break the whole palm kernel into several pieces.
c. The kernel pieces are fed in a roller mill for powder. The palm kernel cake thickness becomes thinner and thinner as it drops from the top to the bottom,about 0.25 to 0.4 mm thick.
d. The kernel flakes are then conveyed to cooking to adjust the moisture content and ensure pure oil.

Palm Kernel Oil Pressing Step
The pretreated palm kernel material is then transfered to the screw oil press for extraction.  Equipped with automatic temperature-controlling device and crude oil filter tank, Our integrated screw oil pressoperates easily and has high oil output. After pressing, the crude palm kernel oil is filtered through the filter cloth and stored in tanks temporarily, when the de-oiled cakes are discharged out. One more thing that the feeder is not just a common feeder but specially designed which ensures the feeding continuously and averagely; thus the pressing process is smooth and efficient.

Palm Kernel Oil Refining 
Like other oil seeds refining process, palm kernel oil refinery has to follow four steps which are degumming, neutralization, decoloring and deodorizing. 
1. At degumming section, hot water is used here as materials like phospholipids and gums are soluable
