关键词:烤烟;烘烤;温度;湿度
摘要:介绍了烤烟三段式烘烤各阶段的操作原则、技术指标及操作方法。变黄阶段:干球起点温度
为 32~35 ℃,变黄期间温度 36~38 ℃,变黄完成温度 38~42 ℃,湿球温度比干球温度低 1~4 ℃;定色阶
段:干球温度 43~54 ℃,湿球温度 37~40 ℃;干筋阶段:干球温度 65~68 ℃,湿球温度 40~43 ℃。并总结
出了三段式烘烤技术的关键点: ①低温变黄,黄干协调; ②适速升温定色; ③重视湿球温度变化等。

Abstract : The operating principles , technique index , and operating methods of three stage curing were introduced.
In yellowing stage : the temperature of dry bulb was 32 35 ℃at the beginning , 36 38 ℃in the duration and 38 42 ℃
at the end , the temperature of wet bulb was 1 4 ℃lower than that of dry bulb ; in fixing color stage : the tempera
ture of dry bulb was 43 54 ℃, and that of wet bulb was 37 40 ℃; in drying stage : the temperature of dry bulb was
65 68 ℃, and that of wet bulb was 40 43 ℃. The keypoints were outlined as follows : 1) yellowing o leaves at
low temp
