CONVECTION OVEN WITH LAMINAR AIRFLOW AND METHOD

摘要

A convention oven (20) with laminar airflow and/or moisture injection. Aradial airflow fan (38) is used to provide a circulating airflow that issubstantially even and substantially turbulence free. The circulating airflowis provided to an oven chamber (28) via a plurality of egress ports (44) thatrim a divider wall (42) disposed between the oven chamber and a fan chamber.The airflow interleaves with a plurality of pans (90) in the oven chamber toprovide a laminar airflow. Moisture is injected into the circulating airfloweither upstream of the fan or by flashing water onto the hot blades (78) ofthe fan from either the low pressure side or the high pressure side of the fan.
