ABSTRACT:
A dryer for curing articles with printings thereon is disclosed. The system includes an exterior housing, an interior lining defining a drying chamber within the exterior housing, means for heating an article within the drying chamber, and a surface for supporting the article within the drying chamber. The dryer housing preferably includes an entrance opening and an exit opening to allow articles to pass through the drying chamber. The dryer may include a conveyor system for automatically moving the articles from the entrance to the exit. The means for heating the articles or directing heated air onto the articles is preferably adjustable in a vertical direction, while the interior lining is made from a non-conductive material, such as fiberglass or a fiberglass cloth. An air duct carrying air into the drying chamber is connected at the one end of the lining, preferably on the dryer's top wall, while a return air duct is preferably connected to a separate bottom wall panel of the drying chamber. The upper air ducts are adapted to pass air from a blower into an air plenum where the air is forced downward onto the article passing through the drying chamber. The lower air duct returns the air to a low pressure inlet of the blower to be recycled. The drying chamber is preferably suspended within the exterior housing and made from a closed-mesh material. This prevents the escape of much heated air from the drying chamber.
