摘　　要：为合理优化烟叶烘烤工艺参数,运用物联网技术采集了河南3个产烟区烘烤温湿度数据,分析烘烤过程的历时和温湿度指标,并结合国内外烘烤工艺进行对比分析。结果表明:①中部和上部烟叶烘烤总时长分别集中在6.5~8.0 d和7.0~8.5 d,上部烟叶烘烤过程中湿球温度的波动相对较大。②豫西和豫南烟区变黄期、定色期和干筋期时长占烘烤总时长的比例约为40%、35%和25%,豫中烟区变黄期历时明显较长(占烘烤总时长55%左右)。③各烟区变黄期、定色期和干筋期的主要稳温阶段分别在40~42℃、43~48℃和61℃以上,变黄后期至干筋期的湿球温度较三段式工艺低1~2℃。④相关分析结果显示,变黄后期~定色中期湿球温度调控与烘烤进程密切相关。结合国内外烘烤工艺,可适当延长变黄期38℃和定色期54℃的稳温时间,合理调控变黄后期至定色期的湿球温度,避免大幅度波动,以促进烘烤过程中烟叶内在化学成分的合理转化。In order to optimize tobacco flue-curing processing parameters,the temperature and humidity data during flue-curing were collected from 3 tobacco planting areas in Henan by using the technology of IoTs(internet of things).The durations and indexes of temperature and humidity of the curing process were analyzed and compared with flue-curing technologies at home and abroad.The results showed that:1)The total curing time of middle and upper tobacco leaves was mainly in ranges of 6.5-8.0 days and 7.0-8.5 days respectively,and the fluctuation of wet bulb temperature was relatively drastic during the flue-curing process of upper leaves.2)The proportions of yellowing,color-fixing and stem-drying durations to total flue-curing time were about 40%,35%and 25%respectively in south and west Henan,while the yellowing duration in middle Henan was longer,accounting for 55%of the total flue-curing time.3)The temperatures during yellowing,color-fixing and stem-drying stages were mainly in ranges of 40-42℃,43-48℃and above 61℃respectively.The wet bulb temperature from the late yellowing stage to stem-drying stage of each area was 1-2℃lower than the three-phase curing technology.4)Correlation analysis indicated that the regulation of wet bulb temperature from yellowing stage to middle color-fixing stage was closely related with the curing process.Considering the flue-curing technology at home and abroad,the durations of yellowing stage at 38℃and color fixing stage at 54℃could be appropriately prolonged,and the wet bulb temperature from late yellowing stage to color-fixing stage should be reasonably regulated to avoid drastic fluctuation,so as to promote the rational transformation of chemical components in tobacco leaves during flue-curing process.
