The Decanter Centrifuge for Sunflower Oil Separation is designed for continuous separation of oil, water, and solid impurities during sunflower oil processing.

It is suitable for sunflower seed oil production, crude oil clarification, oil sludge treatment, and oil recovery applications. The centrifuge separates fine solids and moisture from sunflower oil through high centrifugal force, improving oil purity and reducing valuable oil loss.

• Sunflower crude oil clarification
• Sunflower seed oil purification
• Oil sludge separation
• Oil-water-solid separation
• Vegetable oil recovery
• Press cake liquid recovery
• Edible oil refining pretreatment
• Oil processing wastewater treatment

Fine Seed Residue Removal

Sunflower oil may contain fine solid particles from seed crushing and pressing processes, which are difficult to remove completely.

Oil Loss in Sludge

Residual sunflower oil trapped in solid impurities can reduce product yield and increase production costs.

Oil-Water Emulsion

Moisture and processing additives may create stable oil-water mixtures that affect separation efficiency.

High Moisture Content

Crude sunflower oil and sludge streams may contain excess water, affecting storage and downstream refining.

Variable Feed Conditions

Different sunflower seeds, pressing methods, and production stages create changes in viscosity and solid concentration.

Food-Grade Production Requirements

Edible oil processing requires hygienic equipment materials and clean separation conditions.

Sunflower Oil Feed
→ Pretreatment
→ Feed Tank
→ Decanter Centrifuge
→ Clarified Sunflower Oil + Water Phase + Solid Residue

Recovered Oil → Refining / Storage

Separated Solids → Disposal / Further Processing

Separated Water → Treatment / Recycling

Peony Can Provide

• Sunflower oil sample testing and centrifuge selection
• Food-grade SS304/SS316L contact materials
• Oil-water-solid separation configuration
• Adjustable bowl speed and differential speed
• PLC automatic control system
• Oil recovery and clarification solution
• Wear-resistant scroll protection
• Complete sunflower oil processing integration

Improved Crude Oil Recovery

Recovers hydrocarbons from sludge and reduces oil loss before disposal or further treatment.

Handling of Heavy Crude Residues

Heating and high-torque conveying support viscous sludge containing wax, asphaltenes, and heavy oil.

Sand and Rust Separation

Wear-protected components handle abrasive sand, scale, rust, and tank sediment.

Stable Separation with Variable Feed

Adjustable bowl speed, differential speed, and phase interface adapt to changing oil, water, and solids ratios.

Lower Downstream Treatment Load

Removing oil and solids reduces the volume sent to thermal treatment, wastewater treatment, or hazardous-waste disposal.

Please provide:

• Oil, water, and solids percentages
• Temperature and viscosity
• Particle size and solids type
• Required processing capacity
• Oil recovery and water targets
• Safety and downstream requirements

Peony welcomes cooperation with refineries, crude-oil storage terminals, tank-cleaning contractors, oil-sludge processors, hazardous-waste companies, and environmental engineering partners.
