Abstract: The effects of technical parameters in cylinder drying on the aroma style and roasted sweet aroma note of cigarette were investigated by adopting factor rotation experiment method and the aroma style sensory evaluation method for Chinese-style cigarette. The results showed that within the tested range, cylinder wall temperature, HT steam pressure, the hot air parameters in dryer and cylinder's rotational speed affected the aroma style of cigarette obviously, but the exhausted valve opening did not; cylinder wall temperature ranged from 125 to 132℃ was preferable to enhance the roasted sweet aroma of cigarette. Under the optimized conditions, i.e.HT steam pressure 0.6 MPa, hot air fan motor frequency 30 Hz, hot air temperature 110℃, cylinder motor frequency 32 Hz, cylinder wall temperature128.5℃, the roasted sweet aroma of cigarette increased by 0.35 points(11.1%), and the aroma style of cigarette became more outstanding.
