The Three Phase Decanter Centrifuge for Edible Refined Oil is designed for continuous separation of oil, water, and solid impurities during edible oil processing.

It is suitable for vegetable oil purification, oil sludge treatment, crude oil clarification, and oil recovery applications. The centrifuge uses high centrifugal force to separate three phases efficiently, recovering valuable oil while removing water and solid particles.

In edible oil production, the main challenges include fine solid impurities, emulsified oil-water mixtures, unstable feed conditions, and strict food-grade hygiene requirements.

• Edible refined oil purification
• Vegetable oil clarification
• Palm oil processing
• Soybean oil separation
• Cooking oil recovery
• Oil-water-solid separation
• Oil sludge treatment
• Food-grade oil processing

Fine Solid Impurities

Oil streams may contain fine particles, gums, and suspended solids that are difficult to remove by conventional methods.

Oil-Water Emulsion

During processing, oil and water can form stable emulsions, reducing separation efficiency.

Valuable Oil Loss

Residual oil trapped in sludge or wastewater can reduce product recovery and increase production costs.

Variable Feed Conditions

Different oil types and processing stages create changes in viscosity, solid content, and separation requirements.

Food-Grade Hygiene Requirements

Edible oil production requires clean equipment surfaces and suitable contact materials to avoid contamination.

Continuous Production Requirements

Large-scale oil plants need reliable equipment for uninterrupted separation and stable output.

Edible Oil Feed
→ Pretreatment
→ Three Phase Decanter Centrifuge
→ Refined Oil + Water Phase + Solid Residue

Recovered Oil → Further Refining / Storage

Water Phase → Treatment / Recycling

Solid Residue → Disposal / Further Processing
