The pressing process of palm kernel oil can be briefly described as pretreatment, pressing, filtration, refining, and packaging. Pretreatment involves shelling, kernel shell separation, screening and crushing, then pressing the oil with screw oil press machine, and finally filtering the solid impurities through a plate-frame oil filter and refining it. The video shows the palm kernel crusher, which simulates the effect of crushing palm kernel through crushing plastic. Because of the hard characteristics of palm kernel, crushing into smaller materials can help improve the subsequent oil yield rate and reduce the grinding of the machine, and prolong the service life of the machine.
