Oven Description and Specifications
Cooking in a convection oven differs from cooking
in a conventional deck or range oven since heated
air is constantly recirculated over the product by
a fan in an enclosed chamber. The moving air con-
tinually strips away the layer of cool air surround-
ing the product, quickly allowing the heat to pene-
trate. The result is a high quality product, cooked
at a lower temperature in a shorter amount of time.
Blodgett convection ovens represent the latest ad-
vancement in energy efficiency, reliability, and
ease of operation. Heat normally lost, is recircu-
lated within the cooking chamber before being
vented from the oven: resulting in substantial re-
ductions in energy consumption and enhanced
oven performance.
