Control packages to enhance the efficiency of ovens, dryers/coolers and nut roasters monitor key thermal processing parameters and automatically adjust the equipment to meet final process target specifications. The controls reduce operating costs by monitoring and optimizing thermal equipment operating conditions. Humidity control automatically adjusts the exhaust dampers to maintain a specific humidity in the equipment. Energy performance control combines actual and calculated data that shows operating efficiency of the equipment. Energy data is displayed on an operator interface screen, and the system sounds a warning alarm when efficiency goes outside of the target ranges. Typical areas monitored for efficiency include inlet and discharge product moisture and gas or steam consumption.
