Three Phase Decanter Centrifuge for Olive Oil

Three Phase Decanter Centrifuge for Olive Oil is designed for continuous separation of olive oil, vegetation water, and pomace in olive oil extraction lines.

After olive crushing and malaxing, the olive paste contains oil, water, pulp, skin, stone particles, and fine solids. A three-phase decanter centrifuge separates this paste into three output phases:

• Olive oil phase
• Vegetation water phase
• Pomace / solid phase

Unlike oily sludge treatment equipment, this centrifuge is used for vegetable oil production and olive oil extraction. The main purpose is to improve oil recovery, separate water and solids, reduce manual handling, and support continuous olive oil processing.

This centrifuge is suitable for olive oil processing lines where olive paste needs continuous oil-water-solid separation.

Typical applications include:

• Olive paste separation after malaxing
• Virgin olive oil extraction
• Olive oil-water-pomace separation
• Continuous olive oil production line
• Separation of oil, vegetation water, and olive pomace
• Reduction of solids load before oil polishing
• Primary separation before disc separator
• Small, medium, or industrial olive oil mills
• Olive oil recovery from process streams

The actual separation effect depends on olive variety, paste condition, malaxing effect, water addition, temperature, oil content, solids content, and target oil quality.

The malaxed olive paste enters the rotating bowl through the feed pipe.

Under centrifugal force, the phases separate according to density difference:

• Heavier solids, olive pulp, skin, stone particles, and pomace move outward and form a sediment layer on the bowl wall.
• Vegetation water forms the heavier liquid layer.
• Olive oil stays closer to the center as the lighter liquid phase.

The screw conveyor rotates at a controlled differential speed and continuously pushes the separated pomace toward the discharge end.

At the same time, the oil phase and water phase are discharged separately through different liquid outlets.

The centrifuge continuously separates olive paste into oil, water, and pomace, supporting stable olive oil production.

With suitable paste condition and operating parameters, the decanter helps recover more oil from the olive paste.

Three-phase separation allows olive oil, vegetation water, and pomace to be collected separately.

By removing most water and solids before final polishing, the decanter reduces the burden on downstream disc separation.

The screw conveyor continuously removes pomace, helping maintain steady operation and reducing manual handling.

The machine can be connected with crushers, malaxers, pumps, disc separators, storage tanks, and control systems.

Operating parameters can be adjusted according to paste consistency, water addition, oil content, and production capacity.

Under suitable feed and operating conditions, a three phase decanter centrifuge can typically help achieve:

• 80–95% oil recovery from olive paste
• 20–50% reduction in oil loss in pomace
• 60–85% reduction of suspended solids before oil polishing
• 70–90% water phase separation efficiency control
• More stable pomace discharge
• Lower load on downstream oil polishing
• Improved process continuity
• 8–24 hours per day continuous operation suitability

Final performance depends on olive variety, paste condition, malaxing time, feed temperature, water addition, oil content, solids content, and operating parameters.

If the target oil quality is strict, a disc separator is usually recommended after the decanter for final polishing and residual water removal.

To recommend a suitable three phase decanter centrifuge for olive oil processing, please provide:

• Olive oil process stage
• Capacity requirement, in kg/h, tons/day, or m³/h
• Feed material: olive paste, malaxed paste, or process stream
• Olive variety, if available
• Oil content in paste
• Water content
• Solids content
• Feed temperature
• Paste viscosity or consistency
• Malaxing time and temperature
• Whether water is added before separation
• Target oil recovery
• Target oil quality after decanter
• Target pomace dryness
• Whether a downstream disc separator is used
• Required operating hours per day
• Cleaning requirement
• Food-contact material requirement
• Site voltage and control preference
• Need for skid-mounted system or not

It is used to separate olive paste into olive oil, vegetation water, and pomace during continuous olive oil extraction.

No. The decanter is mainly used for primary separation of olive paste. For final oil polishing and residual water removal, a disc separator is usually used after the decanter.

Yes. With suitable paste condition, malaxing, and machine settings, the decanter can help reduce oil loss in pomace.

It depends on the process route, paste consistency, and separation target. Water addition may help separation in some three-phase systems, but it should be controlled to avoid unnecessary dilution.

Oil recovery depends on olive variety, paste condition, malaxing effect, temperature, water content, solids content, feed rate, and centrifuge settings.
