Plant of palm oil extraction
Palm oil extraction steps
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.
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. Crushing :
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.
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 press cake (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.
Refinery plant of palm oil extraction plant :
Palm oil refinery plant is similar with other oil plant, divided into 4 parts : degumming, deacidification, decolorization, deodorization.
The only difference comes from capacity; In general, batch type oil refinery plant is utilized in palm oil refinery plant with capacity less than 20TPD; And semi-continuous palm oil refinery plant is suggested to capacity from 20-50TPD; finally continuous palm oil refinery plant is used for capacity above 50TPD .
Of course, this is just an option, not necessary. Our engineer can help you design whole palm oil refinery plant according to your capacity and requirements.
