  • Patent number: 5919495
    Abstract: A dough transfer hopper and method for partitioning dough pieces having a precise volume from a dough mass is disclosed. The dough transfer hopper includes a hopper assembly having a pair of inwardly angled end walls and a pair of arcuate side walls defining an upper and lower opening. A cutting assembly is operatively disposed within the lower opening and includes a pair of cutters which operate in a counter-rotating manner to partition a dough piece having a precise volume from a dough mass and deposit the dough piece on a horizontal conveyor assembly. The horizontal conveyor transports the dough piece to an inclined conveyor assembly. The inclined conveyor assembly includes a pair of counter-rotating conveyor belts for transporting the dough piece from the horizontal conveyor to a transfer conveyor assembly for further processing.
