Introduction
Oven Description and Specifications
Cooking in a conveyor 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 continually strips away the layer of cool air surrounding the product, quickly allowing the heat to penetrate. The result is a high quality product, cooked
at a lower temperature in a shorter amount of time.
Blodgett conveyor ovens represent the latest advancement in energy efficiency, reliability, and
ease of operation. Heat normally lost, is recirculated within the cooking chamber before being
vented from the oven: resulting in substantial reductions in energy consumption, a cooler kitchen
environment and enhanced oven performance.
