The invention discloses a wheel cleaning and blowing method. A flange plate on a sliding table I ascends from a low position to a high position, a flange plate on a sliding table II descends from a preset high position to the low position. A upper servo motor is started to drive the sliding table I and the sliding table II to move synchronously to the center, the wheel entering a cleaning system is cleaned in all directions. A lower servo motor is started to drive a rotating disk to rotate 180 degrees, the wheel enters a blowing system from the cleaning system. The upper servo motor stops working, the idle sliding table II moves to the initial position of the left station, the sliding table I moves to the initial position of the right station.

Embodiments provide a unidirectional multi-path kiln with two or more chambers and generally parallel flow paths extending through the kiln, on opposite sides, from charge entry portals at a first end of the kiln to charge exit portals at a second end of the kiln. Moist heated air flowing from the second heated chamber is received in the first chamber and circulated around the lumber charges with one or more fans. The lumber charges proceed in the same direction on the flow paths through the heated second chamber, which may be an existing kiln. Charge exit portals at the distal end of the kiln and/or intermediate charge portals between the second chamber and a third chamber may be provided with insulating members configured to reduce airflow from the second chamber through the charge exit portals.

An air knife for discharging a stream of gas onto a sheet of material. The air knife includes a main body including an inlet portion and an outlet portion, and a plurality of inlet ports. The inlet portion defines a plenum. The outlet portion defines an exit orifice in fluid communication with the plenum. The inlet ports project from the inlet portion and each inlet port comprises a passageway in fluid communication with the plenum. In some embodiments, the inlet ports project from a rear, or trailing, wall of the main body. In other embodiments, the outlet portion terminates at an exit face in which the exit orifice is formed, with a tip region of the outlet portion forming a taper angle of not more than 90 degrees in extension to the exit face.
