Meat Rendering Byproduct Separation Decanter Centrifuge LW720 Continuous Animal Fat Protein Recovery

Rendering plants convert slaughterhouse by products into valuable fat and protein meals, and the separation step between cooked tissue and molten fat determines both yield and product quality. HUADING LW720 meat rendering by product separation decanter centrifuge separator handles the large volumes generated by poultry, pork and beef processing lines, separating the greaves from the fat phase continuously at rates up to several tons per hour. The oversized 720 mm bowl and 90 to 110 kW drive train are built for the round the clock operation of industrial rendering, delivering clear fat with low solids content and a pressable greaves cake with minimal fat carryover.

Wet rendering and dry rendering processes both benefit from the two phase decanter: cooked slurry from the disintegrator is pumped directly into the machine, where centrifugal force separates the solid protein fraction from the liquid fat and water phase. The screw conveyor discharges the greaves while the liquid phase overflows to the fat polishing and evaporation section. Because the separation is continuous and fully enclosed, the LW720 reduces labor, shortens product residence time at high temperature and improves the hygiene of the whole rendering line compared with traditional settling tanks and batch presses.

• High throughput design: The 720 mm bowl processes 10 to 25 cubic meters of cooked slurry per hour, matching the output of large continuous rendering systems.
• Superior fat clarity: Sharp phase separation yields fat with low suspended solids, reducing load on the disc polisher and improving final oil quality.
• Maximum protein recovery: The long cylindrical section retains fine protein particles, lifting meal yield and reducing solids lost to the fat phase.
• Heat resistant construction: The machine handles slurries at elevated temperature, with bearing cooling and material selection suited to hot fat service.
• Enclosed hygienic operation: Fully enclosed processing contains odors and aerosols inside the plant, improving the working environment and meeting stricter hygiene audits.
• Energy recovery friendly: Continuous operation with insulated covers minimizes heat loss, and the recovered fat retains temperature for direct use in the evaporation train.
• Rugged long life build: Heavy frame, planetary gearbox and wear protected conveyor deliver the reliability that rendering plants require during peak slaughter seasons.

The LW720 separates cooked greaves from fat in poultry, pork, beef and fish rendering plants, and processes expired food product, butcher waste and catering residues in higher risk material lines. It also dewaters dissolved air flotation sludge and stick water solids in integrated rendering and wastewater facilities. The recovered fat feeds biodiesel, oleochemical and animal feed fat markets, while the greaves pass to the press and grinder for meat and bone meal or feather meal production. Plants modernizing from batch settling report improved fat yield, lower labor cost and a cleaner separation area, with payback typically achieved within two slaughter seasons.

Given the size of the LW720, HUADING arranges shipment on a steel skid or in break bulk configuration with full protection of the rotating assembly against transit vibration. Each machine completes a factory test including dynamic balancing, overspeed verification and an eight hour water load run before acceptance. The documentation package contains the general arrangement drawing, foundation design, piping and instrumentation diagram, electrical schematic, installation and maintenance manual and the inspection certificate. HUADING provides site supervision for installation, commissioning support and training for the plant crew, together with a twelve month warranty and rapid supply of spare parts for the gearbox, conveyor and main bearings.
