CLEVER HOUSE Crude Palm Oil Production Project

Production Processes of Crude Palm Oil

The palm trees are the perennial oil plants which growing at tropical area, It has features of large capacity and low cost. The palm oil has been became one of the largest capacity edible oil in the world, it's widely used in food processing, cooking, biodiesel production, etc.

The followings are the introduction of crude palm oil production processes:

The fresh fruit bunches(FFB) will get into the fruiting period after growing three years. The FFB will be picked by farmer then transport to the crude palm oil production workshop, the they will be processed:

1. Weighting: The FFB gets into the factory through the weighbridge to weight the raw materials to calculate the production cost.

2. Unloading: the FFB will get through the slide ramp for screening to remove the impurities, then the FFB will get into the conveyor to be transported to sterilizing tank. The time from picking to sterilizing process shall not too long, because over 24 hours the free fatty acid(FFA) will rise which is not good for the following processing.

3. Sterilization: after getting into the sterilizing tank, the FFB will be cooked by high temperature, this section is the preparation for the following crafts.

4. Threshing: the FFB will be soften in the sterilizing process, then through the threshing and screening by the thresher, the palm fruits will separate with the empty fruit bunches.(EFB)

5. The EFB can be transported and stored for fuel or fertiliser.

6. Digesting: after the thresher, the palm fruits will get into this digester, it will stir and crush the palm fruits.

7. Pressing: the crushed fruits will be pressed in the oil presser through spirals.

8. Fiber Separation: the pressed cake fiber will be crushed then get into the winnowing system to separate the fiber and nut.

9. Sepration of Shell and Kernel: after separation from the nut, the nut will get into the cusher to be crushed into shell and kernel. Then the kernel and shell be be separated through winnowing and water washing system, the shell can be used as fuel for boiler, the kernel will be dried for stroage.

10. Oil Clarification:the crude oil(CPO) that after pressing has some content water and impurities, through the pretreatment of sand settling tank and vibrating screen, the crude oil will get into the vertical oil settling tank for heating, finally the crude oil will separated into clear oil and dirty oil. The clear oil will be dried then transported to oil storage tank, the dirty oil will get through sand settling system and certifuge for recycling.

11. Oil Transportation: manufacture the oil transporting pipelines according to the actual conditions.

12. Water Treatment: usually the source water will be lead into factory from the near river, then though primary clarification and filtration, the water will processed by osmotic and reverse osmosis treatment to rech the water standard for boiler.

13. Power System: the power is mainly offer by steam turbine generating unit, and also the diesel generating unit.

Description of Main Section

Unloading Ramp

As for the palm fruit unloading, cleaning, storage

platforms, all hydraulic segmented discharge. they

discharge fruits by all hydraulic type and sectional

type.

Threshing:

Through strong vibration to seprate the fruits

from the fruit bunches.

7

Pressing Section

Digesting Stir the fruit and cook again Pressing : Separate the fruit from nut and get

crude palm oil and nut. The presser adopts

double spiral hydraulic type discharing which

improve the production efficiency greatly.

8

Main Section Description

Sterilization Section

Sterilization: Using high temperature to soften the palm fruits and kill the bacterias(145 90-120 minutes), after this process the fruit will separate from the bunches

easily and also it will increase the moisture content of the

fruits, which will helpful for extracting the oil and

separate the shell and kernel easily. Also this process can

stop the decomposition of enzyme to avoid the rising of

free fatty acid.

9

Clarification Section

Clarification: Separate the crude oil and sludge

to get content 90% oil. The oil from the presser

includes 45%-55% water, sludge and other

things.

Purification: Oil purification process -

improving purity

Drying: use the continuous vaccum drier to

remove the water, the water content can reduced

to 0.1%.

Depericarper Crushing Hydrocyclone Separator: Through floating dry

processing the fruit core and fibers

separated. Fiber and other lighter stuff

was blown appearance

Crushing (Crusher): stone cracked open

grain separation kernel and shell. In

Hydrocyclone, the use of kernel and

core-shell particle proportion to their

separation.

11

power house

Power House (power house): the use of diesel

powered generators and turbine generators,

more environmentally friendly energy

production and electricity consumption to

power.

Steam Boiler

Steam Boilers (Steam boiler):

has a strong output, high thermal

efficiency, stable and reliable operation,

overload capacity, fuel, wide applicability,

environmental protection and many other

advantages.

12

RAW WATER SUPPLY:

Source water piping (RAW WATER

SUPPLY):

the use of remote substation

technology, more energy, improve

production efficiency.

Water Treatment:

After settling, filtration, dosing and other

processes to ensure that the water

quality, but also to ensure oil quality.
