Abstract

A system for optimizing the thermal efficiency of a dryer in which infrared radiation from a source outside the moisture carrying duct is directed into the duct to subject it to the action of the moisture-laden air in the duct to produce resultant radiation which is detected. In response to the detection, the flow of exhaust and fresh air is regulated to hold the moisture content of the air in the duct to a set value considered to be the optimum for the highest thermal efficiency of the dryer loop.
