Apparatus for steam cleaning of a workpiece

摘要

In an apparatus system and method of the invention steam is utilized to clean the exterior of laminated objects, preliminary to powder coating, as well as to effect volatilization of liquid contaminates trapped between lamina thereof. Off-gassing that would otherwise occur when the objects are heated to effect fusion of the powder deposit is thereby avoided. The apparatus comprises means (20) for transporting a workpiece through a cleaning chamber (10) comprising spray means, condenser means and drain means. The system includes cleaning apparatus and further comprises coating means (14,28) and means (16,18) for effecting fusion of a deposit produced by the coating means (14,28).
