ABSTRACT:
A needle chopper apparatus having a rotor with radially extending blades disposed in and along the longitudinal axis of a tube member. While rotating, the blades are in immediate proximity to an inner smooth cylindrical surface of the tube member. A feed chute extends into an inlet of the tube member where the blades react with the edge of the inlet to chop disposable items into particles. The particles go through an outlet in the tube member to a container that holds a disinfectant which is circulated to the feed chute and into the tube while the items are being chopped. One end of the tube is sealed by an annular plug and the other end extends from the top portion of a mounting panel. A housing is formed by an outer cabinet that is slid over an inner cabinet and coupled together by inwardly turned tabs on the outer cabinet. The mounting panel divides the housing into a front compartment and a back compartment. The mounting panel has a top portion offset in a vertical plane from a bottom portion by a horizontally extending intermediate portion such that the bottom portion defines an enlarged area in the front compartment to receive the container. A probe responsive to liquid levels extends into the container and is operatively connected to a sensor disposed in the power circuit to an electric motor. Control components and a timing means are disposed in the rear compartment with the electric motor to prevent operation of the apparatus under certain conditions.
