  • Thermal treating apparatus and process
    Patent number: 5997286
    Abstract: A thermal treating apparatus and process providing convection thermal transfer for elevated processing temperatures and chemical treatment. A recirculation plenum for passage of spent treatment fluid from and fresh treatment fluid to a treatment chamber may contain a thermal control source, a chemical control source, and a blower to provide predetermined programmable temperatures and chemical environments to articles in the treatment chamber. Decreasing cross sectional areas along the length of the treatment chamber cause introduction of fresh treatment fluid at different locations along the length of the treatment chamber to achieve desired uniform thermal and chemical treatment of articles along the length of the treatment chamber.
