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 ramp and stored.
2. Sterilizing section
Fresh palm fruit bunch are airtight sterilized in sterilizer. The purpose is to prevent enzymes broken down, avoiding FFA content in oil further increase; easy threshing machinery; pretreating peel, prepared for the follow-up processing; pre-conditioning stone, reducing the damage kernel.
3. Threshing section
The purpose of threshing is to separate oil palm fruit from the fruit bunch through strong vibration, Threshing equipment is revolving drum thresher. The separated oil palm fruit is ejected then into the pressing 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. Pressing section
Before pressed, oil palm fruit first be carried out cooking, sterilized fruit must be re-heated to make the pulp soft and damage pulp cell structure. Then enter into continuous screw press for pressing. After pressing, oil palm fruit is divided into two parts: oil, water, solid impurities mixture and the press cake (fiber and nuclear). Oil, water, solid impurities mixture inflow to oil purification section by the crude oil gutter; pressed cake into the fiber- recovery section by breaking screw conveyor.
5. Clarification section
Machine-pressed crude oil first diluted with water washing, the fiber material removed from the oil through settlement and filtration, and then carry out continuous settlement, the whole divided into two parts: oil and sediment. Through centrifugal separation and vacuum drying, oil is pumped into the storage tank for storing; oil sediment by filtration and dirt oil separation, oil proceeds second settlement, dirty oil mixture proceeds clarification separation, Skim oil then be carried out a second settlement, sewage pumps to sewage treatment pond for dealing with.
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 tanks, serve oil shed loading and issuing oil regularly to outside. Finished crude oil generally be stored and transported between at 32 ℃- 40 ℃, the working temperature of the palm oil should be at 50 ℃ to 55 ℃. to prevent overheating.
7. 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 separated fiber material is sent to the boiler room as fuel; the separated stone is transported to stone warehouse by pneumatic conveying system for temporary storage.
8. Kernel recovery section
The stone needs intenerate tempering before being broken, the intenerating stone be divided into two or more petal by corrugated crusher, kernel was released. The broken mixture enters into broken mixture separation system; separation system adopts two stage separation and water separation. After separation, shell is sent to the warehouse for temporary storage, as boiler room fuel when necessary; the moisture content of separation kernel falls to below 7% through the hot air to dry. Dried kernel is sent to kernel storage warehouse for storing.
9.Steam-supply section
The fuel of the boiler is fiber, Part of the steam out from the furnace supply to the turbine generator. The rest of the steam for equipment-running supply.
10.Power-supply section
Generally speaking, palm oil factory commonly be set in the palm orchard far away from the city, Power supply capacity is low. So, power-supply should be consider independently, build a captive power plant to meet the electricity needs of the palm oil factory which mainly determined by the electricity-consumption of equipment and auxiliary equipment. In addition, equip another diesel generator for the first time start the plant and emergency use.
11.Raw water treatment section
Water consumption of the palm oil factory include: furnace feeding water, generator cooling water, production and living water, Only the after treated supply water can meet the sanitary requirement. Especially, the furnace supply water should be softened first, After anion and cation exchange resin treatment, meet the requirements of the boiler water, then be treated by deaerator for removing oxygen. At last, pump it into temporary tank for storage.
12. Sewage treatment section
The waste water has high organic matter content, biochemical oxygen demand BOD is about 25000ppm, required by qualified deal before emissions. Pool sewage treatment system is the most used and effective treatment. This treatment system is cost-effective, only needs adequate space, less investment costs.
