In one aspect, a spiral cooking device includes a first cooking zone with air configured to move horizontally therethrough in a first direction, a second cooking zone with air configured to move horizontally therethrough in a second direction different than the first direction, and a spiral conveyor belt at least partially positioned in the first and second cooking zones and configured to transport food product thereon through the first and second cooking zones. In one aspect, a spiral cooking device includes a spiral conveyor belt providing a central opening inside the belt and a conveyor belt drive member positioned externally of the central opening. In one aspect, a conveyor belt cleaning device is provided. In one aspect, a cooking device includes a frame including a plurality of coupled pipes for providing structural support to the device and at least one of the pipes is configured to have liquid pass therethrough.

An oven has a first conveyor, a first burner that directs heat toward the first conveyor from above the first conveyor, and a second burner that directs heat toward the first conveyor from below the first conveyor. A method includes providing foodstuff on a conveyor, exposing the foodstuff to heat directed toward the foodstuff from above the conveyor, and exposing the foodstuff to heat directed toward the foodstuff from below the conveyor. Another oven has a first conveyor and first conveyor insulators that surround the first conveyor and define a first zone. Another method includes introducing foodstuff to a first conveyor belt within a first insulated zone, introducing heat into the first insulated zone, and retaining a portion of the heat within the first insulated zone. Another oven has an insulated cooking zone that closely envelopes a cooking path and an insulated oven zone that substantially envelopes the cooking zone.

A heat transfer system and a broiler that includes a heat transfer system include a heat source. The heat transfer system includes a mixing chamber that surrounds the heat source. An air inlet provides a flow of pressurized air into the mixing chamber. The mixing chamber directs the flow of air past the heat source for direct heating of the flow of air by the heat source. The flow of air is further directed out of the mixing chamber through an outlet to impinge upon a food product.

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.
