ABSTRACT:
The present invention entails a heat exchanger system for a tobacco curing and drying structure that is designed to utilize the heat associated with exhaust air leaving the structure to heat fresh incoming air being directed into the structure. In particularly, the present invention entails a top mounted heated exchanger system including a pair of laterally spaced counterflow heat exchange modules connected to the barn and to a fresh air transfer duct that leads back into the curing and drying structure. Heated exhaust air is routed through the exchange modules before being exhausted to the atmosphere. Counterflowing, but separated, fresh air traveling through the same heat exchange modules is heated by the exhaust air before being introduced into the curing and drying structure.
