Lamb trotters and sheep hooves are among the most valuable by-products in a modern sheep slaughter operation — but only when the hair, dirt and keratinized surface layer are removed quickly, evenly and hygienically. Manual torching is slow, inconsistent and heavily dependent on operator skill. NPW’s flame singeing machine for lamb trotters replaces that bottleneck with a fully conveyorized, gas-fired singeing tunnel engineered for continuous, high-throughput hoof processing.
How the NPW Flame Singeing Machine Works
Trotters are loaded onto a stainless steel mesh conveyor and passed through a singeing tunnel lined with rows of precisely positioned gas burners. Running on LPG or natural gas, the burner banks generate a controlled flame that scorches residual hair, fine wool and surface impurities within seconds. Burner height, flame intensity and conveyor speed are all independently adjustable, allowing processors to fine-tune the singeing depth for different hoof sizes, seasons and customer specifications. A downstream brushing or scraping station and water spray remove the charred residue, leaving a clean, evenly whitened surface ready for further processing or packing.
Key Engineering Features
- Food-grade 304 stainless steel frame, hood and conveyor for full washdown hygiene.
- Modular burner banks with individual flame regulation for uniform singeing across the full belt width.
- Variable-frequency conveyor drive for tunable dwell time and stable product spacing.
- Automatic ignition, flame-failure detection and gas safety valves for reliable, safe operation.
- Insulated tunnel with exhaust hood connection to control heat, smoke and odour in the plant.
- Sloped, fully welded surfaces that support fast cleaning and prevent water pooling.
- Scalable capacity — from compact units to high-output tunnels handling several hundred trotters per hour, with low gas consumption per piece.
Why Flame Singeing Beats Manual Torching
Consistent flame geometry applied at a controlled dwell time delivers the same singeing result on every trotter, hour after hour — reducing labour, rework and rejected product simultaneously.
Because singeing is a continuous in-line process, processors eliminate the need for a row of operators with hand torches, cut gas waste, and gain a repeatable surface finish that meets export and food-safety inspection requirements.
Integration Into NPW Sheep Slaughter and Processing Lines
The flame singeing machine is designed to slot directly into NPW integrated sheep and goat slaughter lines. It is typically positioned after hoof separation and skinning, then linked to washing, blanching or whitening stages, and onward to evisceration support, pre-chilling, portioning and vacuum packing. Inlet and outlet heights can be matched to existing conveyors, and the unit can operate as a standalone module for dedicated by-product rooms.
Hygiene, Safety and Delivery Quality
Every NPW unit is assembled, gas-tested and run-in at the factory before shipment, then crated with protective wrapping, fastened to fumigated pallets and shipped with spare burner nozzles, installation drawings and operation manuals. Emergency stops, heat guards and interlocked safety systems protect operators, while remote commissioning support helps customers achieve stable production from the first shift.
