Palm oil extraction plant devices into 3 plants, palm oil pressing plant, palm oil refinery plant, palm oil fractionation plant. As manufacturer of palm oil extraction plant, we can offer whole line or part of palm oil extraction plant for different capacity with turnkey service.
Here we will introduce you palm oil extraction plant in details as follows:
Palm bunches → Sterilizing → Threshing → Crashing → Pressing → Subsidence and filtration → Refiney → fractionation.
1. Sterilizing :
In general, fresh fruit bunches should be sent into palm oil extraction plant in 24 hours after harvest to prevent palm oil acid value increase caused by fatty enzymes. Palm bunches sterilizing also inactivate fatty enzyme with high temperature to prevent enzyme break palm oil chemical structure.
2. Threshing :
The palm fruit proportion is about 60% of the FFB. In this section, we always use rotating drum thresher to separate palm fruit from the bunches.
3. Crashing :
The purpose of crushing is to destroy palm skin, separate the palm pulp and nuts, pound palm pulp and to damage the cell structure of palm pulp by heating at the same time, which avail the latter pressing section.
4. Pressing :
In palm oil extraction plant, palm oil screw press is common equipment we use, the output of which is mixture of water, oil &residue and presscake (fiber cake).
5. Subsidence and filtration :
Separate the fiber from the mixture derived from pressing by subsidence and filtration, after continuous subsidence we can separate oil and precipitate. With another filtration and vacuum drying, the oil is just crude palm oil as we say.
