Palm oil extraction process

Palm oil is one of the top three popular oil kinds in the world together with soybean oil and rapeseed oil. More and more palm oil plantations are now set up in Africa and Southeast Asia. It is a trend that palm oil mill will be mostly welcomed in near future.You can learn a lot about palm oil extraction equipment here.

The palm oil is extracted from the fresh fruit string and machined. Modern palm oil extraction process is mainly based on automatic machinery. The quality of crude palm oil depends on the pretreatment of palm fruit after harvest, especially on the issue of handling palm seeds. Palm oil extraction process as shown below:

Palm oil extraction process including sterilization, peeling, digestion and pressing, clarification, purification, drying and storage.First, collect the ripe fresh palm fruit strings from the orchards and send them to the factory. The second is the sterilization process. The sterilization process is very important for the quality of the final palm oil. Sterilization inhibits lipase activity in palm fruits and prevents the rise of free fatty acids (FFA). In addition, steam sterilization of FFBs also promotes the stripping of fruits from the string. It can soften the role of fruit, making it easier to oil. Three is threshing part. The purpose of threshing is to separate the palm fruit from the FFB.

After stripping, the fruits are moved into a digester where, the fruits are reheated to loosen the pericarp. The steam heated vessels have rotating shafts to which are attached stirring arms. The fruits are rotated about, causing the loosening of the pericarps from the nuts. Then, it is sent to continuous screw press. After pressing, the palm oil is divided into two parts: the mixture of oil and the press cake. And then is crude oil clarifying section. Oil from the top is skimmed off and purified in the centrifuge prior to drying in vacuum dryer. The final crude palm oil is then cooled and stored. The lower layer from the clarification tank is sent to the centrifugal separator where the remaining oil is recovered. The oil is dried in vacuum dryers, cooled and sent to storage tanks. That is all the information about palm oil extraction processes.
