PRINTER CONVECTION DRYER

摘要

A printed sheet drying apparatus includes, among other components, a nozzle connected to a heated air supply, and an exhaust chamber connected to the nozzle and to a blower. The nozzle comprises a heated air outlet portion. The heated air outlet portion comprises a multi-planar surface having parallel slot openings tapering away from the printed sheet to prevent saturation at the boundary layer. The exhaust chamber has an exhaust opening that matches the shape of the multi-planar surface, and the exhaust opening is larger than the nozzle and is positioned to form an exhaust periphery gap surrounding a periphery of the nozzle.
