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.
Sterilizing section: fresh palm fruit bunch are airtight sterilized in sterilizer. The purpose to prevent enzymes broken down, avoiding FFA content in oil further increase; easy threshing machinery; pretreatment peel, prepared for the follow-up processing; pre-conditioning stone, reducing the damage kernel.
Threshing section: 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。
Pressing section: Oil palm fruit first carry out cooking before pressed, fruit sterilized must be re-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
Clarification section: Machine-pressed crude oil first diluted with water washing, through settlement and filtration, the fiber material removed from the oil, and then carry out continuous settlement, the whole divided into two parts: oil and sediment. Oil by centrifugal separation and through vacuum drying pumped into the storage tank for storing; oil sediment by filtration and dirt oil separation, oil process second settlement, dirt oil mixture process clarification separation, Skim oil then carry out a second settlement, sewage pumps to sewage treatment pond for dealing with。
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 ℃ to 40 ℃, in order to prevent overheating, the working temperature of the palm oil should be at 50 ℃ to 55 ℃.
Fiber separation section: Press cake broken by breaking screw conveyor and then transported into the fiber separation air net and fiber polishing roller for fiber separating. The fiber material separated are sent to the boiler room as fuel; the stone separated are transported to stone warehouse by pneumatic conveying system for temporary storage.
Kernel recovery section: the stone processes intenerate tempering before broken, the intenerating stone by the corrugated crusher be divided into two or more petal, kernel was released. The broken mixture enters into broken mixture separation system; separation system adopts two stage separation and water separation。 Separation shell is sent to the warehouse for temporary storage, and when necessary as boiler room fuel; the moisture content of separation kernel falls to below 7 percent through the hot air to dry. Dried kernel is sent to kernel storage warehouse for storing.
Sewage treatment section: the waste water has high organic matter content, biochemical oxygen demand BOD about is 25000ppm, require by qualified deal before emissions。 Pool sewage treatment system is the most used and effective treatment. This treatment system has cost-effective, only need provide adequate space, less investment costs.
