The palm pressing refining and fractionation production line adopts excellent technology, from palm fruit crushing oil to refining and fractionating.
1.Weighing: Transporting palm fruit into the factory is first weighed by a truck scale for easy settlement and subsequent processing cost accounting.
2.Fruit unloading: FFB after sieving and removing impurities on the ramp into the conveyor machinery to the fermentation tank, the intermediate from picking to fermentation process should not be too long.
3.Fermentation: FFB is cooked under high pressure and high temperature after entering the fermentation tank. This stage prepares for subsequent processes.
4.Fruit removal: FFB is softened during the fermentation process, and the palm fruit is separated from the fruit bundle by the beating and sieving of the fruit removal machine
5.Empty fruit bundles are transported and hoarded to orchards for fertilizer or fuel, or for other purposes.
6.Crushing: the fruit is crushed by stirring and squeezing in the crushing pot after being threshed.
7.Pressing: the crushed fruit is squeezed through a screw press in the press machine.
8.Separation of fibers: The crushed cake-like fibers enter the air separation system to separate the fibers from the core
9.Nucleolar separation: after the separation of the nucleus from the fiber, the nucleus is divided into the kernel and the shell by the nuclear crusher, then the kernel and the shell are separated by the air separation and washing system, and the shell is stored as fuel and then enters the boiler fuel system. The kernel is stored after drying.
10.Oil clarification: the crude oil also contains a certain amount of moisture and impurities after being pressed, which is separated into dirty oil and clean oil after being preliminarily cleaned up by sand sinking tank and vibrating screen and heated and stirred in vertical clarifying oil tank. The dried oil is transported to the wool oil storage tank after drying. Waste oil must be treated by sand removal system and centrifuged.
11.Palm kernel oil: palm kernel oil extraction technology includes crushing, rolling, steaming, and pressing. Its production process and equipment are similar to that of general oil.
Palm oil refining and production line:
1.Filtration: this step is to remove solid impurities in the oil.
2.Degumming: wool oil enters the refining tank, stirred quickly and continuously heated. Then add hot water. It is necessary to control water consumption, temperature and water speed. If phospholipids are suspended in oil for too long, it will not be easy to collect. At the same time, the free fatty acids were removed by adding lye. Batch refining and semi continuous refining are separated by precipitation separation and continuous refining using centrifuge.
3.Decolorization: bleaching clay in vacuum oil, stirring and heating for 25 minutes. After that, the waste clay and oil were separated by filter.
4.Deodorization: heating the decolorizing oil to 100 C and injecting direct steam to remove the odour.
5.Fractionation:This is an important step in palm refining. After that, we got palm oil.
