摘要： Conveyor ovens for cooking food according to various embodiments include variable speed fans to deliver air from a plenum into at least two lower cooking zones below a conveyor of the oven, and at least one variable speed fan to deliver air from the plenum into one or more upper cooking zones above the conveyor, wherein a controller operates the fans delivering air into the lower cooking zones independently of each other and independently of the other fan. The fans can be controlled so that air delivered to a bottom side of the conveyor has a speed that is different in the different lower cooking zones and/or is different than air delivered to the top side of the conveyor. In some cases, the speed of the fans is predetermined and set in accordance with the type of food to be cooked.

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： 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： 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： A conveyor oven having a first mode of operation and a second mode of operation is provided. The conveyor oven generally includes an oven chamber in which food is cooked, a conveyor movable to convey the food through the oven chamber, a burner to generate heat for the oven chamber, at least one blower to circulate air within the oven chamber, and a controller. The burner has a combustion airflow rate, and operates at a first output during the first mode of operation and at a second output that is greater than the first output during the second mode of operation. The blower operates at a first speed during the first mode of operation and at a second speed that is faster than the first speed during the second mode of operation. The controller is responsive to at least one of a burner output and an internal temperature of the oven chamber, and increases the speed of the blower from the first speed during the first mode of operation to the second speed during the second mode of operation responsive to at least one of an increase of the burner output and an increase of the internal temperature of the oven chamber.

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.
