Abstract
A convection oven with laminar airflow and/or moisture injection. A radial airflow fan is used to provide a circulating airflow that is substantially even and substantially turbulence free. The circulating airflow is provided to an oven chamber via a plurality of egress ports that rim a divider wall disposed between the oven chamber and a fan chamber. The airflow interleaves with a plurality of pans in the oven chamber to provide a laminar airflow. Moisture is injected into the circulating airflow either upstream of the fan or by flashing water onto the hot blades of the fan from either the low pressure side or the high pressure side of the fan.
