In general, palm oil milling process starts with sterilisation of the fresh fruit bunches (FFB), continued with the separation of the palm fruits from the bunch, and followed by mashing and mechanical pressing for the extraction of crude palm oil (CPO). The CPO will go through clarification and purification to complete the palm oil milling process. Conventional palm oil milling process requires dilution of crude oil to increase its fluidity and later enhances the separation of oil from its by-product at the clarification stage. Though good milling practices recommend using hot water for crude oil dilution, many palm oil millers are using the steriliser condensate and empty fruit bunch (EFB) liquor as dilution to recover some oil that would be lost in both streams, thus increase the mill’s oil recovery.
