Abstract: By analyzing the drying process, a new control modewas developed.The water evaporated from the input cut tobacco and the temperature of cylinder wall were stabilized to achieve constant moisture content of dried cut tobacco during normal drying stage.A low-pressure steam nozzle controlled by an electromagnetic valve was installed in the hot-air duct to imitate the air status in the cylinder at the normal drying stage in order to minimize over-dried heading and tailing cut tobacco.The stability of moisture content of dried cut tobacco was improved and the quantity of over-dried heading and tailing cut tobacco was reduced considerably by the new drying control mode.
