Commercial Meat Grinder

Overview

The commercial meat grinder reduces trimmed meat into mince at up to 300 kg per hour. A 1.1 kW induction motor drives a feed auger through a gear reduction, forcing meat past a rotating knife and a perforated plate. Plate hole size sets the grind: coarse 8 mm plates for sausage and chili, fine 4.5 mm plates for burger and pâté.

Construction

The machine stands on the Body & Housing, a stainless shell and base plate on rubber feet that house the drive and isolate vibration. Power comes from the Induction Motor, a single-phase induction unit rated for continuous duty, coupled to the Reduction Gearbox: a helical gear train that drops motor speed to roughly 200 rpm at the auger while multiplying torque to handle gristle and frozen edges without stalling.

The working section is the Grinding Head, the classic auger-knife-plate stack. Meat dropped into the throat is conveyed forward by the auger flights, which also compress it. At the head face a reversible four-wing knife rotates against a stationary plate; the scissor action between knife edges and plate holes shears the meat as it extrudes. A ring nut clamps the stack and sets knife-to-plate pressure, the key adjustment for clean cutting versus smearing.

The Control Box carries forward, reverse, and stop controls plus the motor overload; reverse clears jams by backing the auger out. Mains power enters through the Power Cord. The head, auger, knife, and plates all remove without tools for cleaning and to swap plate sizes between products.
