ABSTRACT:
Incoming fresh air, which is introduced for heating in the furnace of a bulk curing barn for tobacco, travels the length of the barn in heat exchange relationship in a direction opposite to that of the hot, moist exhaust air leaving the curing chamber. The incoming fresh air is further preheated by means of a solar roof immediately beneath which the fresh air flows on its way to the furnace. The curing chamber itself is made substantially air tight, is insulated, and has the floor thereof elevated above the ground, thereby preventing heat loss as much as possible. The barn is sometimes portable so that it can be loaded with tobacco adjacent or near the tobacco field and moved to whatever location desired for the curing operation.
In a preferred embodiment, additional amounts of fresh air are introduced beneath the edges of a corrugated surface which forms the solar roof, which air streams are heated both by the solar furnace from above, and also by the hot exhaust air in an exit duct immediately therebeneath.
