2. Sterilization section

Use scraper conveyor and fruit cage to transport fresh palm fruit bunches to the sterilization tank for high temperature sterilization (145℃, 90-120 minutes) to effectively control the free fatty acid content in palm fruit and provide basic conditions for subsequent processing.

Type of sterilization tank: 1. Horizontal 2. Vertical

Customers can choose the sterilization tank method according to actual conditions.

3. Threshing section

After the fresh palm fruit bunches are sterilized, they are transported to the palm fruit threshing machine, which separates the fruit particles from the fruit bunches by rotating and beating.

The main features are as follows:

1. Coaxial design: Double-row self-aligning bearings are used to ensure coaxiality, strong stability, low failure rate and easy maintenance.

2. Gradual start: The torque is large when the main shaft starts, which causes great harm to the equipment and transmission equipment. We adopt hydraulic couplers to gradually start from the motor end and use V-belts to connect the motor reducer, to ensure the stability of the start-up phase.

4. Palm fruit oil pressing section

The main equipment in the palm oil pressing section is the crushing tank and palm oil press machine:

1. The crushing tank is mainly used to crush and heat the fruit before the entire fruit bunch enters the press;

The main models are: 2000L, 3000L, 3500L, 4500L.

2. The twin-screw oil press is a twin-screw extruder that crushes and produces pulp, and is equipped with a hydraulic system as an auxiliary to ensure that the residual oil in the filter cake is reduced and the integrity of the palm kernel is guaranteed.

The main models are: 5t (FFB) / h, 10t (FFB) / h, 15t (FFB) / h, 20t (FFB) / h

5. Crude oil filtration part

1. Initial filtration of hard and fiber impurities in the pressed crude palm oil;

2. Double-layer filter screen, upper filter screen 20 mesh, lower filter screen 40 mesh

3. The filtered crude palm oil enters the crude oil tank, and the hard and impurities are recovered and squeezed.

6. Oil clarification section

The squeezed crude palm oil is filtered, settled, centrifuged, and vacuum dried to separate the water and residue in the crude oil to obtain pure crude palm oil.

The main equipment is as follows:

1) Palm hair vibrating screen (remove impurities and hardness)

2) Vertical clarified oil tank (separation of dirty oil and clean oil)

3) Disc centrifuge (separation of water in pure oil)

4) Vacuum drying system (remove residual water in clean oil)

5) Sand brake cyclone (remove sand in oil)

6) Three-phase horizontal screw centrifuge (separation of oil, water, and residue from dirty oil)

7) Crude palm oil storage tank (palm oil storage)

7. Storage and transportation of crude palm oil

1. Heating and storage of palm crude oil

2. Palm oil transportation

8. Empty fruit bunch processing section

Residual oil in empty fruit bunches is recovered and empty fruit bunches are shredded for use as fertilizer or boiler fuel.

9. Fiber separation section

The kernel and fiber are separated by floating drying. Fibers and other light things are blown out. The fibers in the pressed cake are separated to obtain pure kernels.

10. Palm kernel recovery section

The kernel and the shell are separated by wind screening and water washing according to the different specific gravity. The separated kernel is dried to reduce the moisture content to about 6-8% for storage. The separated palm shell is transported to the boiler as fuel.

12. Power plant

Power is supplied to the palm oil factory through steam power generation and diesel power generation, which is more environmentally friendly and energy-saving.

13. Source water treatment system

After sedimentation, filtration, dosing and other processes, the water quality can be ensured, and the palm oil quality can also be guaranteed.

1. Storage and sedimentation treatment of palm oil factory water

2. Filter factory water

14. Boiler water treatment system

1. Select the water treatment system according to the water quality, which is generally divided into softening system and osmosis reverse osmosis (RO system)

2. Remove K+ and Mg+ in boiler water to ensure that the boiler does not scale and extend the service life and thermal efficiency.

15. Wastewater treatment of palm oil plant

Recovering oil from waste oil can reduce oil loss and water pollution.

16. Power control system of palm oil plant

Diesel generators and steam turbine generators need to be switched, and each section operates independently as a unit, which is more convenient for the operation of the entire palm oil mill and can ensure the coordinated work of the entire palm oil plant. Key equipment adopts PLC control to ensure the operating efficiency of the equipment.
