  • Patent number: 8959793
    Abstract: An oven configured for drying a container. The oven includes a housing defining an interior space including a supply chamber and a return chamber. A conveyor is configured for movement within a portion of the interior space of the housing defined by a plurality of semi-circular shaped duct sections connected at each end of the semi-circular shaped duct sections to a straight duct section. Each duct section includes two side walls coupled to a back wall defining a continuous U-shaped duct path through which the conveyor moves. The oven is further configured to provide a temperature difference between any two points within the interior space of the oven housing controlled to plus or minus two degrees Fahrenheit, by a uniform air flow throughout the oven. The uniform air flow is facilitated by the sizing and spacing of various circular orifices and slotted orifices in the continuous duct path.

  • Patent number: 7264467
    Abstract: A convection oven that achieves a substantially enhanced degree of air flow through the use of a special nozzle design. Turbo flow air nozzles create an air flow pattern to provide higher velocity airflow with a smaller fan size and ductwork. The turbo flow air nozzles include main supply nozzles that direct high velocity air through air entrainment and mixing sections that entrain air from the oven interior to generate the increased air flow in a heat transfer zone of the oven. Appropriate ductwork is provided to direct air from a fan or fans to the supply nozzles to generate a high velocity air flow therethrough.
