摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method and arrangement is provided for setting a peak operating power level for an oven having an oven compartment, a user interface, and a controller having a memory with a maximum peak operating power level stored therein. The method includes the steps of displaying an oven set-up user interface window on the user interface during an initial start-up of the oven; in response to an input for selecting a maximum output for the oven, displaying a maximum output user interface window on the user interface. Further, after input of a peak operating power level, the method stores the peak operating power level in the memory and selectively provides a power control signal to generate heat that corresponds to the peak operating power level. The oven is either an electric oven or gas oven. In operation, the oven heats at the peak operating power level, which is less than the maximum peak operating power level.

摘要： A method of controlling a cooking oven including a contactor, a relay, and a heating element, the contact, the relay, and the heating element in a series-type configuration. The method includes during a first operation, placing the contactor in a closed position, and during the first operation, selectively providing power, via the relay, to the heating element. The method further includes during a second operation, bypassing the relay while the contactor is in the closed position, and during the second operation, providing power to the heating element.

摘要： A control system for a control-compartment cooling fan of an oven. In one embodiment, the control system includes a sensor for sensing an operating condition of a motor of the cooling fan. The operating condition is selected from the group of a motor current and a motor RPM. A controller is communicatively connected to the sensor and is configured to receive the operating condition from the sensor, compare the operating condition to one or more predetermined tolerances and, when the operating condition exceed at least one of the one or more predetermined tolerances, generate an interrupt command. A heating control element is communicatively connected to the controller and configured to interrupt operation of a heating element in response to receiving the interrupt command. The control system may also include a user interface communicatively connected to the controller.
