A conveyor oven includes a controller configured to change the operation of a first set of burners and a second set of burners from a cooking mode to an energy saving mode based at least in part upon detection of the absence of food in the oven chamber. The first set of burners operating at a first intensity during the cooking mode and are off during the energy saving mode. The second set of burners operating at a first intensity during the cooking mode and being adjustable to a different intensity during the energy saving mode, where the second set of burners produce heat during the different intensity.

Apparatus and method for controlling a conveyor oven

A conveyor oven has a modulating gas valve which raises and lowers the thermal output of a burner that heats the oven. A bypass line passes a minimum amount of gas to prevent the burner from completely shutting down during periods while the oven remains above a threshold demand for more heat. Electrical isolation is provided between temperature controlling devices to prevent an electrical feed back which might otherwise prevent a complete shut down of the oven during hazardous conditions.

Conveyor oven having an energy management system for a modulated gas flow

An automatic oven cooks or bakes a food product over a timed period of time during which a burner delivers heat to the oven cavity. Thermocouple sensors in the cavity control a modulator which regulates the amount of gas flowing to the burner to maintain a uniform temperature in the oven. A conveyor carries the food product in order to time the baking period.
