In Hungary many types of curing barns are used for the production of flue-cured tobacco. In these equipments the air-circulation is the usual (from bottom to up), which is not advantageous in the rack-type barns. In the old equipment there are big fans with too much air-volume and high velocity. In our institution a curing system has been developed. It means a new curing method and equipment, which is an energy-saving and multi-purpose construction. Briefly, it means a counter air-circulation (from top to down). It favours the water-loss of the tobacco-leaves arranged in the racks. The curing equipment is complex, installed with special heat and sun trap, and can be used out of the curing season, for example as a greenhouse in spring.
