Palm oil processsing steps
1)Palm oil mill have main ten parts: Reception Station,Sterilizer,Threshing,Pressing,Clarification, Kernel Recover, power station, boiler station, water treatment plant, oil storage tank.
2)We use the Fresh Palm Fruit Bunch, because the palm fruit rancidity is very fast, if the rancidity will be influence the palm crude oil acid value, if the acid value is very high, the refining efficiency will drop.
3)Generally speaking, the palm oil mill be mainly located in Nigeria, Malaysia, Indonesia etc..
1) Reception Station: used for loading palm fruit bunch from plantation,transport to sterilizer.
Reception station adopt steel structure and concrete structure. Save equipment cost and construction cost.
Have hydraulic control system, hydraulic door open/off automatic achieve continuous operation.
Reduce operator, operate more easily and improve work efficiency.
2)Sterilizing Tank: The sterilizing tank uses direct steam to process, which can reduce activity of the enzyme,prevent the rancidity, ensure the good quality of the crude oil. At the same time, it is good for the threshing process.
3)Threshing station: Fresh palm fruits separate from bunches by thresher rotary drum rotating. Palm fruits are conveyed to digester by elevator.Empty bunches are conveyed out of factory by scraper conveyor.
4)Digester: Inside of digester, there are some baffle and stirring arm, under the drive of top motor.Baffles break the palm fruit, then heat palm fruit pulp. So that can press oil easily. Get higher oil yield.
Meanwhile there is directly steam inlet digester, to adjust material moisture.
5)Pressing Machine:The palm fruit oil yield increases by adjusting material moisture and temperature in digester. Digester uses liquid level control, so material can distribute automatically and equipment runs fully automatically. Pressing machine uses hydraulic control system to adjust spacing between pressing bolts. So it can be suitable for various palm fruit species and guarantee the oil yield.
6) Kernel Recovery Station: Using palm kernel cracking and separating machine to separate palm shell and kernel, according to their different density. So it has high separation rate. There are some fiber cover the palm nut, in order to get palm kernel, should remove the fiber and palm shell.Fiber and shell is very good resource for boiler fuel.
7)Clarification Station: Oil purifying system, using latest technology, on the premise that guarantee oil quality, we try our best to reduce machine investment and oil loss. In actual production, it has been verified that using new technology can reduce oil loss below 1.3%.
8)Power station: customers usually use generators to produce power for the palm oil mill plant.
9)Boiler station: Offering high temperature steam to sterilizer the palm fruit bunch and so on.
10)Water treatment plant: Offering water for the palm oil mill plant.
11)Oil storage tank: used to store the crude palm oil. Inside the tank, there is heating pipe to prevent the palm oil becoming solid.
