Abstract: A method and apparatus for efficient dispensing of desiccant canisters into containers is disclosed. The apparatus includes a microprocessor that monitors a plurality of sensors, and applies control signals to a servomotor that controls a rotary disc that transports desiccant canisters from a drop chute to containers. The containers pass through the apparatus via a conveyor system. Control signals determine the position and presence of desiccant canisters and containers to ensure proper operation. Error detection and recovery features are provided to handle the case of a missing desiccant canister, and halt the apparatus upon detection of an unrecoverable error.
