Abstract
In order to investigate the changes of moisture content and surface temperature of cut tobacco during cylinder drying, a mathematical model for describing the surface temperature change of cut tobacco was established, further, the effects of cylinder wall' s temperature on the surface temperature were studied, and the difference of surface temperature change characters between flue-cured and burley tobacco was analyzed. The results showed that; 1) the kinetic model basing on the balance equations of mass and heat transfer could reflect the dynamic change characters of cut tobacco' s surface temperature during drying; 2) with the rising of cylinder wall' s temperature, the temperatures of flue-cured tobacco B2F and burley tobacco C3F raised more rapidly, and their surface temperature raised to higher levels; under the same drying conditions, the surface temperature of flue-cured tobacco changed faster than that of burley tobacco; 3) along with the reduction of moisture content, the surface temperature went through three stages; quick rising, slow rising, and quick rising.关键词
