Tobacco roasting process of intensive hothouse

The invention discloses a tobacco curing method for intensive flue-curing barns, which comprises curing step of three stages: a yellowing stage, a leaf drying stage and a stem drying stage. The difference between the method and the conventional curing method is that a second dry bulb thermometer is arranged in a tobacco loading layer for detecting the tissue temperature of tobacco leaves besides a dry bulb thermometer and a wet bulb thermometer arranged in the curing room. Fully considering the problem of heat generated by breathing of wet tobacco tissue, the tobacco curing method can control the temperature and the humidity in the flue-curing barn as well as the tissue temperature of the tobacco leaves. Specifically, the temperature of the wet tobacco tissue in the yellowing stage must be controlled within a change range of physiological and biochemical temperature of the wet tobacco leaves, which is the key for preventing the tobacco leaves from curing bad, thus ensuring the curing quality of intensive flue-curing barns.
