ABSTRACT:
The present invention relates to a bulk tobacco curing and drying structure that comprises an elongated main housing having a cross sectional area substantially arcuate shaped and adapted to receive and support bulk tobacco or other crop material therein for curing and drying. In one embodiment disclosed herein, the elongated housing is of a generally cylindrical shape and supported by an underlying cradle support structure. Defined internally within the cylindrical housing is a drying chamber having laterally spaced supports for supporting a plurality of bulk tobacco containers or racks therein over a defined plenum area within the cylindrical housing. A forced air furnace system provided with the curing and drying structure acts to circulate air vertically through bulk tobacco contained within the drying chamber, and generally maintains a desired temperature level therein during the curing and drying process.
