Effects of Technical Parameters of Cylinder Drier on Sensory Quality of Flue-cured Tobacco

Simple correlation, stepwise regression and contribution rate analysis were used to analyze the effects of the technical parameters of cylinder drier on the sensory quality of tobacco, the temperature of cylinder wall, steam pressure of HT63, rotation speed of cylinder, opening of hot air valve and temperature of hot air were experimented with uniform design. The results showed: 1)the steam pressure of HT63 significantly positively correlated with impact, while the other technical parameters presented no significant correlation with sensory quality indexes;2)among the tested technical parameters, the cylinder wall temperature contributed greatly to aroma quality, aroma quantity, offensive odor, cleanness and total panel test score, contribution also was made by hot air temperature and HT63 steam pressure to impact, hot air valve opening and HT63 steam pressure to concentration, HT63 steam pressure to smoothness and irritation, hot air temperature to dryness though to a lesser extent.
