烤烟烟夹烘烤过程中叶间隙风速的研究

The Research on Wind Speed of Leaves Gap in Tobacco-clamp during Curing Process

为了解烘烤过程中烟叶的叶间隙风速变化以及影响风速变化的主要因素,对密集烤房中棚烟叶的8个位点的叶间隙风速、烤房的干湿球温度进行实时监测记录,并测定烘烤过程中叶片与主脉的含水率.结果表明:1)烘烤过程中叶间隙风速总体表现为先降低后升高的趋势,其中位点6的风速较低;2)湿球温度对风速的直接通径系数为﹣0.974 9,叶片含水率对风速影响的直接通径系数为0.404 4.因此,在烘烤过程中,可通过提高位点6的风速以及控制烟叶含水率和湿球温度,进一步改善烟叶质量.

In order to study the changes of wind speed of tobacco leaves gap in curing process and the main factors that affect the wind speed change, the leaves gap wind of 8 loci in middle layers in the dense curing barn and the wet bulb temperature and dry bulb temperature were recorded in curing process, then the water content in leaf blade and main veins were determined. The results showed that 1） the wind speed of leaves gap showed a trend of decreasing firstly and then increasing, but the wind speed at the loci 6 was lower. 2） The direct path coefficient of the wet bulb temperature with the greatest influence on leaf gap wind speed was - 0. 974 9 in the curing process. The direct path coefficient of the leaf water content with a greater effect on leaf gap wind speed was 0.4044. So in the curing process, the quality of tobacco leaves can be further improved by improving the wind speed at the loci 6, controlling the moisture content of the leaves and the wet bulb temperature.
