Three Phase Decanter Centrifuge for Animal Fat Rendering

Three Phase Decanter Centrifuge for Animal Fat Rendering is designed for continuous separation of animal fat, water phase, and protein-rich solids in rendering and animal by-product processing lines.

In animal fat rendering, the feed stream may contain melted fat, process water, fine protein solids, bone particles, connective tissue residue, meat slurry, and suspended impurities. A three phase decanter centrifuge separates these mixed phases continuously and helps recover usable fat, reduce fat loss, remove solid impurities, and lower the load on downstream polishing or refining equipment.

A three phase decanter centrifuge separates rendering feed into fat phase, water phase, and solid phase.

The actual separation result depends on raw material type, fat content, water content, solids content, temperature, viscosity, and operating conditions.

The animal fat rendering stream enters the rotating bowl through the feed pipe.

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

• Heavier protein solids, bone particles, meat fibers, and tissue residues move outward and form a sediment layer on the bowl wall.
• The water phase forms the heavier liquid layer.
• The animal fat phase stays closer to the center as the lighter 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 recovered fat phase and water phase are discharged separately through different liquid outlets.

The centrifuge helps recover usable fat from mixed rendering streams and reduce fat loss in water or protein solids.

The machine separates fat, water, and solids continuously, making it suitable for rendering and animal by-product processing lines.

The screw conveyor continuously removes protein-rich solids, bone particles, meat fibers, and residue, helping maintain stable operation.

Continuous feeding, separation, fat discharge, water discharge, and solids discharge help improve production rhythm.

The machine can be connected with cookers, presses, buffer tanks, disc separators, dryers, storage tanks, and control systems.

It supports animal by-product valorization by recovering useful fat from rendering streams and reducing waste in the process.

To recommend a suitable three phase decanter centrifuge for animal fat rendering, please provide:

• Rendering process stage
• Feed material: cooked slurry, press liquor, melted fat mixture, offal slurry, or rendering residue
• Animal source: beef, pork, poultry, mixed animal by-products, or other source
• Capacity requirement, in m³/h, tons/day, or kg/h
• Fat content
• Water content
• Solids content
• Protein solids content, if available
• Bone particle content, if available
• Feed temperature
• Feed viscosity or fluidity
• Particle size or solid characteristics
• Whether the fat is free or emulsified
• Current process before centrifuge
