摘要
采用标准化气流上升式密集烤房,研究了烘烤过程关键点(38、42、46或47、54℃)稳温时间和不同湿度组合,对烟叶外观、内在品质、感官质量和经济性状的影响。结果表明,在烟叶烘烤的各关键温度点稳温维持较长时间再配合前期(38℃)相对较高的湿球温度和42℃以后适中的湿球温度(T2)条件能够使烟叶物理、生理生化变化过程充分,烤后烟叶外观质量与感官质量评价得分最高,化学成分含量适宜,比例协调,但存在身份变薄、杂色烟比例增多而影响经济形状的趋势。因此,密集烘烤中在干球温度42℃以后维持中等的湿球温度并适当控制稳温时间,避免变黄过度,可兼顾烤后烟叶质量和效益。
The effects of various combinations of stable time at key temperatures （38, 42, 46, 47, 54 ℃） and humidity on the appearance, chemical components and economic values of tobacco leaves during bulk curing were studied in order to provide a theoretical basis for optimization and perfection of standardized curing technology by bulk curing barn built in 2011. The result showed that, if the stable time of key curing temperature maintained a long time, with a relatively high wet bulb temperature （38 ℃） and moderate wet bulb temperature since the 42 ℃ of dry bulb temperature, the physical and physiological and biochemical reactions in tobacco leaves were sufficient, both the appearance quality and smoking quality reached the highest, the chemistry compositions of the leaves was harmonize, but the body was somewhat thinner, more variegated leave. Therefore, we should maintenance suitable humidity and control stable time of dry bulb temperature to avoid yellow since 42 ℃ during bulk curing, which can balance flue-cured tobacco leaves quality and efficiency.
