Abstract:
In an essentially recycling air oven, a system for rapid air temperature modification comprising:(A) a shell having an inlet for receiving a stream of air and an outlet for discharging a stream of air;(B) associated with said shell, a first path and a second path disposed between said inlet and said outlet to guide independent streams of air through said shell;(C) a heating means disposed within said first path for heating a stream of air passing through said first path;(D) a chamber disposed adjacent and before said outlet in which the stream of air leaving said first path joins and mixes with the stream of air leaving said second path so that a single, thermally-uniform stream of air passes through said outlet; and(E) control means for maintaining the temperature of air leaving said outlet at a level according to a predetermined temperature.
