Abstract: Conveyor ovens for cooking food according to various embodiments include one or more passive tubes in a plenum positioned opposite one or more burner tubes, wherein the passive tubes have outer walls with apertures therethrough. In some cases, a burner assembly for a conveyor oven includes at least one burner tube extending into a plenum and positioned to receive at least a portion of a flame emitted by the burner assembly, wherein a rifling plate extends through the burner tube and is slidingly positioned within the burner tube. Also, in some cases a baffle in a plenum of the oven is positioned opposite the burner tube and defines a fluid conduit having an entrance into which air heated from the burner tube is received and an exit separate from the entrance and through which air is discharged.

Abstract: An oven with a sensor positioned to detect an event that will cause a decrease in the internal temperature of a tunnel. The oven includes a controller configured to increase the thermal output of a heating element in anticipation of the upcoming decrease in the internal temperature. In some embodiments, the oven is a conveyor over and the sensor is positioned to detect a food item approach the tunnel on a conveyor. In some embodiments, the amount of current provided to an electric heating element is increased by increasing the target temperature. In some embodiments, the amount of current provided to the electric heating element is increased by a predetermined offset.

Abstract: Conveyor ovens for cooking food product according to various embodiments include a tunnel having an entrance and an exit, a conveyor to move the food product through the tunnel, and a canopy at the entrance and/or at the exit of the tunnel. The canopy can include a top spaced above the conveyor, and a skirt extending downwardly toward the conveyor, wherein the top, skirt, and conveyor define a partially enclosed space through which food product carried by the conveyor passes. Some conveyors ovens have a first configuration in which a cooking chamber of the oven has a first length, and a second configuration in which the cooking chamber is extended to have a longer second length, wherein food product on the conveyor is cooked along the entire first length in the first configuration, and is cooked along the entire second length in the second configuration.
