ABSTRACT:
An air knife or air nozzle manifold for drying or blowing off passing articles moved by a conveyor system is provided with a coupling that permits rotation of the air knife or air nozzle manifold relative to the air inlet duct leading from a blower. The air knife or air nozzle manifold has opposing ends located equidistant from a longitudinal axis of rotation relative to a stationary element of the coupling. Thrust nozzles are provided at each of the opposing ends of the air knife or air nozzle manifold to deflect a certain portion of the air from the plenum chamber to provide thrusting jets of air that rotate the air knife or air nozzle manifold about the longitudinal axis. The flow of air emitted from the air knife or air nozzle manifold is thereby directed onto the passing articles from different directions as the articles move by. The efficiency of drying and blowing off the articles to be processed is thereby significantly improved.
