Abstract
A tobacco curing enclosure includes roof vents, sidewall fan assemblies with heaters, a humidity augmentation system, and internal air circulation devices. Internal temperature and humidity monitors are connected with a control system for the fans, vents, heaters, humidity augmentation system and air circulation devices. The control system in conjunction with the enclosure allows humidity inside the enclosure to be controlled according to a predetermined schedule despite the ambient weather conditions, thereby enhancing the quality of cured tobacco.
