Knife for meat mincer Stalgast 721010

A knife is the cutting edge of a meat mincer, slicing through sinew and fat as the worm auger forces the meat against the perforated plate. The knife's sharp blades rotate at the same speed as the auger, shearing the meat cleanly so that each piece is pushed through the holes in the plate. This shearing action determines the texture of the mince: a sharp, well-aligned knife produces even, unbroken strands, while a dull or misaligned one tears the fibres and creates a mushy, uneven result.

To use the knife, the operator first removes the end cap and locking ring from the mincer head, then slides the existing knife off the auger shaft. The new knife is placed onto the shaft, ensuring its central hub aligns with the auger's drive splines. The perforated plate is fitted over the knife, the locking ring is tightened, and the end cap is replaced. Once the mincer is reassembled, the operator starts the motor and feeds the meat into the hopper. The knife's rotation is continuous, so the operator monitors the output for consistency and adjusts the feed rate as needed.

The knife is a precision-ground component, designed to maintain its edge through repeated use. Its fitment is specific to the mincer models it matches, ensuring the blades align exactly with the plate's perforations. In a working kitchen, this alignment reduces strain on the motor and prevents blockages, allowing the mincer to run at full capacity without overheating or jamming.

This knife fits Stalgast meat mincers with article numbers 721121, 721124 and 721129. It is listed in the catalogue under mincer spares and accessories, where it appears alongside plates, worms and end caps for the same line of equipment.
