Introduction To Fractionation Technology
Fractionation is the process where the crystallization of saturated triglyceride takes place in a mechanical equipment called the crystallizer. Crystallized oil is further passed through a ﬁlter where separation of solid and liquid phase takes place. Solid phase remains in the chamber. Liquid phase comes out through the taps and is collected in the storage tank. Entire process takes place in several steps which including: Oil heating, oil charging, and crystallization, ﬁltration, squeezing and cleaning of ﬁlter.
Salient Features Of Jagdish Crystallizer For Palm Oil Dry Fractionation
- Large heat transfer area with regard to the oil charge in the Crystallizers i.e. 10 sq. m. per ton of oil.
- Optimal position of the heat exchange surfaces with regard to the impellers and therefore to the oil circulation in the vessel.
- All parts of the processed oil are really driven too close to the heat exchange surfaces. The cooling programme is accurately followed. At the end of each cooling step the temperature difference between cooling water and oil is close to 1’C.
- The duration of the crystallization process for either the crude palm oil or the RBD is 5 hours for any size of cooler/ crystallizer from 2 to 26 tons charge.
