Dough preparation apparatus and associated methods. The dough preparation apparatus can store and be configured to execute a plurality of dough preparation recipes. In one example, the dough preparation apparatus is configured for thawing or slacking frozen dough and conditioning the dough prior to baking. The dough preparation apparatus facilitates production of baked bread having higher and more consistent quality.

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.

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.

A conveyor oven for cooking food and having an oven chamber in which food is cooked; a conveyor moveable to convey food within the oven chamber; a burner assembly operable to emit a flame to heat air for cooking food moving within the oven chamber on the conveyor; a burner tube extending into a compartment and positioned to receive at least a portion of the flame emitted by the burner assembly; and one or more passive tubes in the compartment positioned opposite the burner tube, wherein elongated baffles are located between adjacent passive tubes, wherein a baffle plate is located between the burner and passive tubes to restrict airflow from the burner tube to the passive tube, and/or wherein shelf assemblies in the oven enable movement (and in some cases removal) of a shelf with a corresponding fan and/or motor without disturbing other shelves and their corresponding fans and/or motors.

A method for cooking is disclosed. In response to an oven being selected to cook a food item, a determination is made whether or not any oven is being engaged in cooking. If no oven is being engaged in cooking, then temperature-control mode is utilized to control oven temperature of the selected oven. If one oven is currently being engaged in cooking, then another determination is made whether or not the total current demand by the two ovens to cook respective food items exceeds a predetermined current limitation under temperature-control mode. If the total current demand does not exceed the predetermined current limitation, then temperature-control mode is utilized to control oven temperature of the two ovens. If the total current demand exceeds the predetermined current limitation, then time-control mode is utilized to control oven temperature of the two ovens.
