  • Patent number: 5039295
    Abstract: An apparatus for forming viscous flowable material, such as meat and food, into specific shapes such as meatballs and cylindrical fillings for egg rolls. The apparatus includes a container having side walls and a curved pressure plate positioned between the side walls. A rotor is located between the side walls and it has a rim facing the curved, adjustable pressure plate so that the rim and the pressure plate converge in the direction of rotation of the rotor to define a flow channel of decreasing volume for the viscous flowable material. A motor is provided to rotate the rotor in the direction of convergence with the adjustable pressure plate. Scrapers are carried by the rotor to force the viscous material flow into the channel toward the convergence of the rotor and the pressure plate to compress the viscous flowable material. A mold cavity is provided located relative to the rotor rim and the pressure plate to receive the viscous flowable material from the flow channel.
