Abstract
A conveyorized oven that provides uniform cooking with control of the heater and/or the conveyor belt speed. The oven includes a controller that monitors power consumption of the heater and uses the power consumption to control the heater and/or the speed of the motor that drives the conveyor belt. The power consumption is monitored by counting the on time cycles of a switch that connects and disconnects the heater to a power main. Changes in the power consumption due to changes in loading are used by the controller to reduce recovery times of the oven temperature to a set temperature by controlling the heater and/or the motor. By using a stepper motor, there is no need for a gear box.
