温湿度对白肋烟处理质量的影响

Effects of air temperature and humidity on quality of toasted burley tobacco

现行白肋烟处理工艺主要通过控制加料含水率、烘焙温度、烘焙时间、干燥含水率等工艺参数来控制白肋烟的处理质量。从工艺的角度来讲 ,白肋烟的烘焙处理也是一个烟叶干燥的过程。本文通过对烟叶干燥特性的分析 ,论述了影响白肋烟烘焙质量的主要工艺控制因素 ,并通过不同温湿度条件的加工工艺试验 。

Currently, the quality of toasted burley were controlled by casing moisture, heat temperature, heat time and exit moistute of the drying process It is generally held that burley toasting is in essence a tobacco drying process In this paper, the principle of tobacco drying and the main control factors of toasted burley quality were discussed Four typical kinds of domestic burley tobacco were toasted under different air temperature and humidity regime Results of sensory evaluation and chemical compounds change of toasted burley showed that 1) air humidity in drying section was closely related to the quality of toasted burley tobacco; 2) different control methods of air temperature and humidity should be applied according to the quality of burley tobacco
