Abstract
A mixer having a discharge screw centrally located between first and second side walls and disposed in a cavity provided in the bottom. The discharge screw has (a) a shaft with a first end that extends through a first end wall and (b) a driven end opposite the first end of the shaft, with the driven end being connected to a motor shaft for rotating the discharge screw in at least one direction. The driven end has a recessed portion that extends into the second end wall of the vessel. The mixer may include a deflector that is fixed to the second end wall and extends toward the first end wall and is located between the mixing blades and the discharge screw.
