Abstract: An enhanced convection heat-treatment system and method is configured to direct airflow with a plurality of air-paths past product, such as loaves of bread, to impart heat to the product and past a heating system to impart heat to the air. The enhanced system operates in a first mode with airflow along each of the plurality of air-paths in a first direction. The enhanced system operates in a second mode with airflow reversed although substantially along each of the same plurality of air-paths in an opposite second direction to assist in uniform heat-treatment of the product. For instance, as a convection oven, the enhanced convection heat-treatment system could distribute airflow evenly over a baked product resulting in an even bake of the product.

Abstract: A convection oven includes a heat exchanger section and a product receiving section, the product receiving section including a door to provide access thereto. An air flow system includes at least one blower and an air flow path for enabling air to circulate from the heat exchanger section where it is heated, into the product receiving section for transferring heat to food products, and back to the heat exchanger section for further heating. The air flow path includes a passage providing flow communication between the heat exchanger section to the product receiving section, where the passage is located proximate to a wall and configured such that heated air from the heat exchanger section is directed along an internally facing surface of the wall so as to attach to and flow along the internally facing surface of the wall from one side of the product receiving section toward an opposite side of the product receiving section.

Abstract: A dough proofing cabinet includes a chamber having a chamber panel with a plurality of openings distributed thereon. A heating element may be located to the backside of the chamber panel, or elsewhere outside of the chamber. Operation of a blower causes air flow through the chamber panel openings, past the heating element and back to the chamber along at least one air flow path. In one example both upper and lower air flow paths are provided. An intermediate panel with one or more openings may be provided adjacent the chamber panel to create an area that receives air passing through the wall openings.

Abstract: An oven construction includes a heat exchanger with substantially vertically arrange heat exchange tubes and an anchor-free and adjustable floor construction for the baking chamber.
