Working Principle Of Meatball Making Machines

The working principle of an automatic meatball machine begins with an auger extruder feeding meat into the grinding mechanism. The forming system consists of three stages-a storage cylinder, a mixing cylinder, and an extrusion cylinder-designed to handle raw material storage, mixing, and final shaping, respectively. These cylinders are separated by partitions, the opening and closing of which are controlled by a motor-driven rack-and-pinion mechanism. Inside the extrusion cylinder, the meat paste is forced by an auger through a mold outlet to form the meatballs.
Filled-meatball machines utilize dual hoppers to separately manage the meat paste and the filling, injecting the filling into the center of the meatball via a nozzle. Some models employ variable-speed motors and pressure-regulating valves to independently adjust the feed pressures for the paste and filling, ensuring precise synchronization of their respective dispensing speeds. The feeding process combines primary auger-driven feeding with secondary quantitative delivery via a piston pump.
