Three Phase Decanter Centrifuge for Food Waste Oil Recovery is designed for separating oil, liquid, and organic solids from crushed food waste slurry and kitchen waste streams.
Food waste is usually not clean waste oil. It contains high moisture, grease, food residue, fibers, starch, protein solids, sand, and suspended organic matter.
A three phase decanter centrifuge helps recover grease from the mixed slurry while reducing the oil and solids load before downstream treatment.
Food waste slurry has more unstable composition than collected waste oil. Oil, water, and organic solids are usually mixed together, and the solid content can change significantly from batch to batch.
If oil and solids are not removed early, the system may face:
A three phase decanter centrifuge helps separate recoverable grease, water-rich liquid, and organic solids before the remaining material enters further treatment.
Crushed food waste slurry enters the rotating bowl through the feed pipe.
Under centrifugal force, heavier organic solids, fibers, starch, protein particles, and sand move outward and form a solid layer on the bowl wall.
The water-rich liquid phase forms the heavier liquid layer, while the oil or grease phase stays closer to the center as the lighter liquid phase.
The screw conveyor continuously pushes separated organic solids toward the discharge end. The oil phase and liquid phase are separated internally and collected according to the process design.

The system helps recover grease from high-moisture organic slurry before downstream treatment.
Removing oil early can reduce floating grease, pipeline blockage risk, and wastewater treatment pressure.
Food residue, fibers, starch, protein solids, and sand can be discharged continuously by the screw conveyor.
Separating oil and heavy solids helps make the remaining liquid phase more stable for digestion or further biological treatment.
Sealed structure and flushing options can help reduce organic build-up and improve site operation.
The centrifuge can be integrated with shredding, screening, heating, buffer tanks, oil collection, liquid treatment, and solids discharge systems.
Under suitable feed temperature and operating conditions, the system can typically help achieve:
Final performance depends on food waste composition, oil content, water content, solids content, particle size, temperature, viscosity, and operating parameters.
To recommend a suitable three phase decanter centrifuge for food waste oil recovery, please provide:
It is used to recover oil or grease from food waste slurry while separating water-rich liquid and organic solids.
Used cooking oil recovery mainly treats collected waste oil. Food waste oil recovery treats mixed kitchen waste slurry with more water, organic solids, fibers, starch, and food residue.
Usually yes. Large bones, plastics, shells, packaging pieces, and hard foreign matter should be removed before feeding.
Heating may improve grease separation when the feed is viscous or the grease is difficult to release from the slurry.
Yes. It can remove part of the oil and heavy solids before anaerobic digestion or other downstream treatment.
Yes. The system can include screening, feed pump, buffer tank, heating unit, centrifuge, oil collection, liquid outlet, solids discharge, and PLC control.
