1.Raw materials storage section:
Fresh palm fruit bunch must be first measurement recorded by the pound into the plant, then unloaded to loaded fruit slopes and stored.
The fresh palm fruit bunch are airtight sterilized in sterilizer.The purpose to prevent enzymes broken down, avoiding FFA content in oil further increase; pretreatment peel, prepared for the follow-up processing; pre-conditioning stone, reducing the damage kernel.
This process adopts the different type Boiling vessel for sterilizing the palm fruit. If for small cacpacity ,it directly use waste palm branch or wood for the fuel to reduce down the cost.
The purpose of threshing is the oil palm fruit be separated from the fruit bunch through strong vibration, Threshing equipment is revolving drum thresher. The oil palm fruit separated be ejected then into the press section. Empty fruit bunch be ejected to the yard from the other side of the revolving drum, or shipped out from the plant as palm orchards slipcover to recycling use, or burning in the locale as fertilizer for agricultural land.
4.Digester & Pressing section:
Oil palm fruit first carry out cooking before pressed, fruit sterilized must be pre-heating for the soft- pulp, and damage pulp cell structure. Then enter into continuous screw press for pressing.Oil palm fruit pressed is divided into two parts: oil, water, solid impurities mixture and the press cake (fiber and nuclear). Oil, water, solid impurities mixture by the crude oil gutter inflow to oil purification section; press cake by breaking screw conveyor into the fiber- recovery section.
5.CPO Clarification section:
Directly use vertical screen to remove out the sludge ,then use plate filter to remove out the gums from the crude palm oil ,to get the good quality CPO .
this process does not use any water .
6.Finished oil storage and transportation section:
Finished crude oil is stored in storage tanks, the capacity of oil storage tank is two 1000 tons, serve oil shed loading and issuing regularly oil to outside. Finished crude oil generally be stored and transported between at 32 ºC to 40 ºC, in order to prevent overheating, the working temperature of the palm oil should be at 50 ºC to 55 ºC.
