Three Phase Decanter Centrifuge for Palm Oil

Three Phase Decanter Centrifuge for Palm Oil is designed for continuous separation of crude palm oil, water, and solid impurities in palm oil processing lines.
In palm oil mills, the feed stream may contain oil, water, fine fiber, sludge, sand, and suspended solids. A three-phase decanter centrifuge separates these mixed phases continuously and helps improve oil recovery, reduce oil loss, and lower the load on downstream clarification or purification equipment.
Unlike oily sludge treatment equipment, this centrifuge is used for vegetable oil processing and crude palm oil clarification. The main purpose is not waste disposal, but oil recovery, oil clarification, water separation, and solid residue discharge in palm oil production.
This centrifuge can be used in different stages of palm oil processing where oil, water, and solids need to be separated.
Typical applications include:
- Crude palm oil clarification
- Palm oil mill process stream separation
- Oil-water-solid separation after pressing or settling
- Palm oil sludge phase oil recovery
- Clarification tank underflow treatment
- Recovery of oil from palm oil process residue
- Separation of fine fiber, sludge, and suspended solids
- Reduction of oil loss in solid or water phase
- Pretreatment before disc separator or final oil polishing
- Continuous palm oil production line separation
A three-phase decanter centrifuge separates the feed into three main phases:
| Phase | Description | Purpose |
|---|---|---|
| Oil phase | Crude palm oil or recoverable oil | Collected for further clarification or refining |
| Water phase | Process water or vegetation water | Discharged or sent to further treatment |
| Solid phase | Fiber, sludge, sand, suspended solids | Continuously discharged as solid residue |
The actual separation result depends on feed composition, oil content, water content, solids content, temperature, viscosity, and pretreatment condition.
The palm oil process stream enters the rotating bowl through the feed pipe.
Under centrifugal force, the phases separate according to density difference.
- Heavier solid particles, fiber, sludge, and sand move outward and form a sediment layer on the bowl wall.
- The water phase forms the heavier liquid layer.
- The oil phase stays closer to the center as the light liquid phase.
The screw conveyor rotates at a controlled differential speed and continuously pushes separated solids toward the discharge end.
At the same time, the oil phase and water phase are discharged separately through different liquid outlets.

The centrifuge helps separate recoverable oil from oil-water-solid mixtures, reducing oil loss in sludge or water phase.
Continuous Oil-Water-Solid SeparationThe machine separates oil, water, and solids continuously, which is suitable for palm oil mill production lines.
Reduced Load on Clarification TanksBy removing solids and separating water earlier, the centrifuge can reduce the burden on settling or clarification systems.
Better Downstream Oil ClarificationThe recovered oil phase can be sent to disc separation, polishing, storage, or refining with lower solids load.
Continuous Solid Residue DischargeThe screw conveyor continuously discharges fiber, sludge, and suspended solids, helping maintain stable operation.
Flexible Process IntegrationThe centrifuge can be installed before oil polishing, after clarification tanks, or as part of a palm oil recovery and clarification system
With suitable feed temperature, stable feeding, proper oil-water interface control, and correct machine selection, a palm oil three-phase decanter centrifuge can typically help achieve:
- 70–95% recoverable oil recovery from suitable palm oil process streams
- 30–60% reduction in oil loss in sludge or water phase
- 70–90% removal of suspended solids from the recovered oil phase
- 60–85% reduction in solid load before downstream disc separation or final clarification
- 30–60% reduction in sludge or residue volume before further treatment or disposal
- Continuous separation of oil, water, and solids for palm oil mill process streams
- More stable crude palm oil clarification before polishing, storage, or refining
- Lower burden on clarification tanks, settling tanks, or disc separators
- Improved process continuity in palm oil production lines
Actual performance depends on feed composition, oil-water-solids ratio, temperature, viscosity, fiber content, emulsification level, and downstream oil quality requirements.

It is used to separate crude palm oil, water, and solid impurities from palm oil process streams. It helps recover oil, discharge water, and remove fiber or sludge solids continuously.
Yes, when the feed contains recoverable oil and suitable separation conditions are available, the centrifuge can help reduce oil loss in sludge or water phase.
Palm oil separation performance is affected by temperature and viscosity. Heating or temperature control may be needed when the oil phase is too viscous or the feed temperature is unstable.
Yes. The system can include feed pump, buffer tank, decanter centrifuge, oil collection tank, water collection tank, solids discharge system, pipelines, valves, and PLC control.
