palm oil production line, palm oil filtration, palm oil olein, fractionation

The oil palm tree grows in regions around the equator. It is a tropical tree with leaves about 5 metres long. Originally found in West africa, the oil palm tree is now mostly cultivated in Indonesia and Malaysia, the world’s largest palm oil-producing nations.

Palm oil has a balanced fatty acid composition in which the level of saturated fatty acids is almost equal to that of the unsaturated fatty acids,

Palm oil, extracted from the palm fruit, is one of the few natural oils to have a high amount of saturated fat. After it’s pressed by the machine, it is crude palm oil. Crude palm oil refining process includes following steps.

Filtration: The purpose of this step is to remove the granular impurities in palm oil.
Degumming: Pumping crude oil into oil refining tank, stirring quickly, and simultaneously heating by steam or heat-transfer oil. Then add hot water. Control the water amount, temperature and water adding speed. If phospholipid lasts long suspended in oil, which is hard to gather to make flocculent precipitate. We can rise up the speed of adding water, conversely slow down. At the meanwhile, adding alkali to remove the FFA.

Palm olein is the liquid fraction obtained from fractionation of palm oil. The fractionation process involves a physical process of cooling the oil under controlled conditions to low temperatures, followed by filtration of the crystals through membrane press, the liquid olein and solid stearin are products of fractionation, and they are the major products exported.
