Oven Description and Specifications
Cooking in a convection oven differs from cooking in a
conventional deck or range oven since heated air is con-
stantly recirculated over the product by a fan in an en-
closed chamber. The moving air continually strips away
the layer of cool air surrounding the product, quickly al-
lowing the heat to penetrate. The result is a high qual-
ity product, cooked at a lower temperature in a shorter
amount of time.
Blodgett convection ovens represent the latest advance-
ment in energy efficiency, reliability, and ease of opera-
tion. Heat normally lost, is recirculated within the cooking
chamber before being vented from the oven: resulting in
substantial reductions in energy consumption and en-
hanced oven performance.
