In order to explore the optimum curing technique of middle and upper leaves of K326,the effects of different curing temperature and humidity on quality and grade structure were studied.The results showed that the tobacco leaves of treatment 2 had high appearance quality.The temperature of middle part tobacco leave getting yellow is 39—42 ℃;web bulb temperature 36 ℃;during the colority stage the temperature raised 55 ℃ by the speed of 1 ℃ every 2 h;web bulb temperature 37—38 ℃;dry stem stage the temperature is 68 ℃;web bulb temperature 40 ℃.The temperature of upper part tobacco leave getting yellow is 38—42 ℃;web bulb temperature 36 ℃;during the colority stage the temperature is 47—55 ℃;web bulb temperature 38 ℃;dry stem stage the temperature is 68 ℃;web bulb temperature 41 ℃.The tobacco leaves of treatment 2 are with orange,enough oil,moderate thickness,strong colority, coordinate chemical components with moderate sugar and nicotine contents,best sensory quality with elegant and sufficient aroma, mellow and comfortable tobacco gas,and highest the ratio of mid-high grade leaves,average price and the ratio of positive group tobacco.So the treatment 2 was the optimal curing technology.Meanwhile,the results illustrate that adjusting temperature and humidity and heating rate would improve tobacco leaves quality and industrial usability during bulk curing process.
