Three Phase Decanter Centrifuge for Rice Bran Oil Sludge Separation
Three Phase Decanter Centrifuge for Rice Bran Oil Sludge Separation
Description

The Three Phase Decanter Centrifuge for Rice Bran Oil Sludge Separation continuously separates recoverable rice bran oil, aqueous liquid, and concentrated solids from conditioned oil sludge.

It is suitable for crude rice bran oil tank bottoms, extraction residues, degumming sludge, wax-containing sediment, bran fines, filter residues, and oily wastewater generated during refining.

Typical Applications
  • Crude rice bran oil sludge clarification
  • Extraction plant settling-tank residues
  • Degumming sludge oil recovery
  • Rice bran fines separation
  • Wax-containing oil sludge treatment
  • Refinery washing-water pretreatment
  • Filter-aid and sediment removal
  • Oil recovery from tank-bottom sludge
  • Oily wastewater volume reduction
  • Pretreatment before oil polishing
Rice Bran Oil Sludge Challenges

High Wax Content

Rice bran oil naturally contains waxes that may crystallize at lower temperatures and increase sludge viscosity.

Controlled heating helps maintain fluidity and stable feeding.

Fine Bran and Filter Solids

Bran fines, husk particles, filter aid, and suspended impurities can remain in the oil.

Screening and stable feed preparation improve solids discharge.

Gums and Stable Emulsions

Phospholipids, proteins, soap, and fine particles may stabilize the oil-water interface.

Heating, pH adjustment, or suitable conditioning may be required before separation.

Variable Sludge Composition

Oil, water, wax, gums, and solids content may vary between extraction, storage, and refining stages.

Adjustable bowl speed, differential speed, and phase interface help maintain stable separation.

Product Quality Protection

Excessive temperature or long holding time may affect oil color and oxidation stability.

The feed temperature and residence time should match the refining process.

Rice Bran Oil Sludge Separation Solution

Peony provides three-phase separation for oil recovery, water removal, and sludge reduction.

Rice Bran Oil Sludge
→ Screening
→ Heated Feed Tank
→ Three Phase Decanter
→ Oil + Water + Solids

Recovered Oil → Filtration / Refining
Water Phase → Further Treatment
Solids → Recovery / Disposal

Peony Can Provide

  • Sludge testing and selection
  • Heated tank and feed pump
  • Adjustable phase interface
  • Food-grade wetted parts
  • CIP cleaning
  • PLC and dual-VFD control
How the Decanter Centrifuge Works

1. Conditioned Sludge Feeding

Screened and heated rice bran oil sludge enters the rotating bowl through a controlled feed pipe.

Agitation keeps wax, gums, and solids uniformly suspended.

2. Solids Sedimentation

Centrifugal force moves bran fines, filter aid, wax solids, and dense impurities toward the bowl wall.

A concentrated solids layer forms.

3. Oil-Water Separation

The lighter rice bran oil remains closer to the bowl center.

The heavier aqueous phase forms a separate outer liquid layer.

4. Continuous Solids Conveying

The screw conveyor transports settled solids toward the conical discharge end.

Concentrated sludge is discharged continuously.

5. Three-Phase Discharge

Recovered oil and aqueous liquid leave through separate outlets.

The concentrated solids discharge continuously for further treatment or disposal.

Main Advantages

Recovery of Valuable Rice Bran Oil

Reduces oil loss in tank sludge, degumming residues, and refining waste.

Wax and Fine-Solids Removal

Separates wax particles, bran fines, filter aid, and suspended sediment.

Continuous Three-Phase Separation

Produces separate oil, aqueous liquid, and concentrated solids streams.

Reduced Refinery Sludge Volume

Lowers the volume sent to filtration, drying, or disposal.

Adaptable Operating Parameters

The phase interface and rotational speeds can be adjusted for changing sludge conditions.

What Data Is Needed for Selection?

Please provide:

  • Oil, water, and solids percentages
  • Wax and gum content
  • Temperature and viscosity
  • Feed capacity
  • Required oil quality
  • Downstream refining process
FAQ

Can the centrifuge separate wax from rice bran oil?

It can remove suspended or crystallized wax solids. Dissolved wax may require controlled cooling or winterization before separation.

Is heating required before feeding?

It is often recommended when the sludge contains wax or has high viscosity. The temperature should remain within the oil-quality requirements.

Can it treat rice bran oil degumming sludge?

Yes, after evaluating the gum content, emulsion stability, water ratio, and oil-recovery target.

Can the recovered oil enter refining directly?

Possibly. Moisture, gums, wax, solids, free fatty acids, and color should be tested before further refining.

How are bran fines and filter aid handled?

Dense particles settle against the bowl wall and are continuously conveyed to the solids outlet.
