Abstract: In order to analyze the changes of physical properties of,moisture content and aroma components in cut strips in dual-temperature cylinder drying,the filling values and elasticity of cut strips dried in cylinder at constant temperatures of 100,120,130,140,150℃ and at temperature combinations of 150/100(first section temperature/second section temperature),140/100,130/100 and 120/100℃ were determined,and the contents of petroleum ether extracts and aroma components in cut strips dried at constant and varied temperatures were compared.For the temperature combination of 140/100℃,experiments were conducted by changing cylinder wall temperature when tobacco moisture contents reached 19%,17%,15% separately.The results showed that:1) Under high/low temperature combination conditions,the drying efficiency of cut strips was obviously promoted by rising cylinder wall temperature at earlier drying stage.2) Comparing with constant high temperature drying,high/low temperature combination was helpful to improving the elasticity and filling value of cut strips,meantime,the aroma components,such as brown reaction products and carotenoids degradation products,increased obviously.3) Under dual-temperature drying,the filling value of and total aroma component content in dried cut strips would decrease,while its elasticity would increase when temperature transition point was the moisture content reached 15% instead of 19%.
