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.

1. A conveyor oven comprising: an oven chamber in which food is cooked;a conveyor moveable to convey the food through the oven chamber;a finger positioned within the oven chamber and including a nozzle generally directed toward the conveyor;a burner to generate a heat output, the burner having a combustion airflow rate generated at least in part by a combustion blower and having a variable heat output;at least one air-circulating blower configured to direct impingement air heated by the burner through the nozzle of the finger to cook food positioned within the oven chamber, wherein the at least one air-circulating blower operates at variable positive air-circulating speeds;a temperature sensor within the oven that generates temperature signals indicative of the temperature of air circulating within the oven, heated by the burner, and directed through the finger and nozzle to impinge upon food product upon the conveyor; anda controller that receives the temperature signals generated by the temperature sensor, andin response to the received temperature signals indicating an increase in the temperature of cooking air used to impinge upon and cook the food product, is configured to set the air-circulating speed of the at least one air-circulating blower from a first positive air-circulating speed to a second faster positive air-circulating speed to maintain a continuous positive air circulation in the oven chamber, wherein the controller increases the air-circulating speed of the at least one air-circulating blower over a predetermined period of time. 2. The conveyor oven of claim 1, wherein the burner has a gas flow rate that is increased from a first flow rate to a second flow rate based at least in part on the received temperature signals indicating a need for more heat output from the burner. 3. The conveyor oven of claim 1, wherein the combustion blower airflow rate is increased from a first positive airflow rate to a second positive airflow rate in response to the received temperature signals indicating a need for more heat output from the burner. 4. The conveyor oven of claim 1, further comprising a valve to adjust the combustion blower airflow rate. 5. The conveyor oven of claim 1, wherein the burner has a gas flow rate that is adjusted between at least two positive flow rates based in part in response to the received temperature signals indicating a change in oven temperature. 6. The conveyor oven of claim 5, wherein the controller adjusts the combustion blower airflow rate and the gas flow rate to maintain a substantially constant ratio between the combustion blower airflow rate and the gas flow rate over a range of operation. 7. The conveyor oven of claim 1, wherein the at least one air-circulating blower is a first air-circulating blower, the conveyor oven further comprising a second air-circulating blower, and wherein the first air-circulating blower and the second air-circulating blower are separately adjustable to create two different heating zones in the oven chamber. 8.

The conveyor oven of claim 13, wherein the at least one air-circulating blower is not shut down until the oven temperature drops below a threshold temperature. 15. The conveyor oven of claim 1, wherein the at least one air-circulating blower operates at the first positive air-circulating speed in a self-cleaning mode of the oven. 16. The conveyor oven of claim 1, wherein the combustion blower generates a combustion blower airflow rate that is decreased from a first positive airflow rate to a second positive airflow rate in response to the received temperature signals indicating a need for less heat output from the burner. 17. The conveyor oven of claim 1, wherein the oven is equipped with two or more temperature sensors, and the controller is configured to vary the interpretation of the temperature signals received from the two or more temperature sensors to suit the food product. 18. The conveyor oven of claim 1, further comprising a valve to adjust a burner gas flow rate and a valve to adjust an airflow rate of the combustion blower, both of which are operable to maintain substantially constant amount of excess air in the burner during high and low heating load periods. 19. A conveyor oven comprising: an oven chamber in which food is cooked;a conveyor moveable to convey the food through the oven chamber;at least two fingers each positioned within the oven chamber and including a nozzle generally directed toward the conveyor;a burner to generate a heat output, the burner having a combustion airflow rate generated at least in part by a combustion blower and having a variable heat output;a first air-circulating blower configured to direct impingement air heated by the burner through the nozzle of a first finger of the at least two fingers to cook food positioned within the oven chamber and a second air-circulating blower configured to direct impingement air heated by the burner through the nozzle of a second finger of the at least two fingers to cook food positioned within the oven chamber, wherein each of the first and second air-circulating blowers operates at variable positive air-circulating speeds;a temperature sensor within the oven that generates temperature signals indicative of the temperature of air circulating within the oven, heated by the burner, and directed through the finger and nozzle to impinge upon food product upon the conveyor; anda controller that receives the temperature signals generated by the temperature sensor, andin response to the received temperature signals indicating an increase in the temperature of cooking air used to impinge upon and cook the food product, is configured to set the air-circulating speed of at least one of the first and second air-circulating blowers from a first positive air-circulating speed to a second faster positive air-circulating speed to maintain a continuous positive air circulation in the oven chamber, wherein the controller increases the air-circulating speed of at least one of the first and second air-circulating blowers over a predetermined period of time. 20. The conveyor oven of claim 19, wherein the first air-circulating blower and the second air-circulating blower are separately adjustable to create two different heating zones in the oven chamber.
