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.
Introduction Oven Components Baking Chamber --- products pass through the baking chamber on the conveyor belt for cooking. Conveyor Belt Assembly --- stainless steel chain link (conveyor) belt and support that carries product through the oven. Crumb Pan --- catches crumbs from products on the conveyor.
