ABSTRACT:
This invention provides a conveyor and tunnel oven, where the conveyor is continuous, the tunnel oven is gas fired, having its ignited and heated gases passed through a tubular system, being attracted by one or more blowers, to generate by conduction infrared energy to furnish curing to products passing along the continuous conveyor. A control system is provided for controlling the operating parameters such as conveyor speed, regulating emitted gas, the velocity generated by the blowers, and the capacity of the BTUs created, during operations of the oven.
