Abstract

A feeder for transporting particles, such as carbon dioxide pellets, includes a container for receiving particles and a suction nozzle having an inlet end disposed adjacent a discharge area of the container. The nozzle is configured generally as a pipe having a circular cross-sectional area. The nozzle is reciprocally carried by the feeder so that the inlet end may be moved into and away from the particles to prevent the particles from clogging. The container bottom is generally shaped as a chute to direct/move the particles toward the discharge area. A vibrator may be used to assist in the movement of the particles. The nozzle may be reciprocated manually or automatically. Alternatively, the nozzle may be stationary and a mechanical assist included to move the particles toward the discharge area.
