Palm Oil Mill Process(Threshing)

Using drum type thresh machine to separate palm fruit from palm fruit bunches;

Palm Oil Mill Process of Threshing:The sterilized palm fruit bunches(FFB) will be transported into the drum thresher, and the palm fruit will be separated from the stem as the drum rotates.  The stalk does not contain any oil, so the losses in the threshing process mainly come from the palm fruit still attached to the stalk after threshing.

Threshing station uses strong vibration to make separation of palm fruit from palm bunches.  Raw materials after sterilization are sent to bucket elevator through damp car, and elevated into threshing machine.  Palm fruit separates from bunches, sent to next section elevator through screw conveyor.  Empty bunches through conveyor and charger, are transported to certain place for further treatment by car.

The remaining empty fruit bunches(EFB) at this stage are used as fuel: they are used to create heat for the steam boilers. These empty bunches are also composted. Microorganisms break down the biomass and produce some nutrients. empty bunches contribute to increasing soil fertility by giving nutrients, and also helps to retain water, used in the oil palm plantations. 

Palm fruit threshing station can vibrate palm fruit from palm bunches efficiently, It makes further preparation for next step palm fruit oil press processing.
