摘　　要：[目的]探讨几种缩小密集烤房层间温差的材料的应用效果。[方法]为解决密集烤房烘烤过程中上下棚烟叶变黄干燥不均匀、局部烟叶易挂灰或烤青等问题，采用化纤毛毯、棉纱布、无纺布等材料置于烤房顶部，以缩小上下棚间的温度差，观察上棚下棚温湿度变化情况，及对烤后烟叶质量的影响。[结果]试验表明，在密集烤房使用化纤毛毯或棉纱布一类吸水物质后，能显著提高上棚湿球温度水平，平均提高0．24-0．31℃（最高点达0．70℃），且化纤毛毯处理能明显缩小同层干湿球温度差，相对时照平均缩小0．41℃：化纤毛毯处理、棉纱布处理烤后烟叶外观质量、经济性状、单位能耗相对对照也有明显改善。[结论]研究可为解决密集烤房烘烤中上下棚烟叶变黄干燥不均匀、局部烟叶易挂灰或烤青等问题提供参考。[ Objective ] To study several smaller materials applied to reduce the interlayer temperature of bulk curing barn. [ Method ] In order to solve the problems of tobacco leaf uneven yellowed, greened leaf and hanged ash, we put the chemical fiber blankets, cotton gauze, non- woven fabric and other materials on the top of bulk curing barn during baking to reduce the temperature difference between the upper and lower canopy. [ Result] The results show that using chemical fiber blankets or cotton gauze can significantly improve the wet bulb temperature of the upper canopy. The average temperature is raised by of 0.24 - 0.31℃. The treatment of chemical fiber carpet can significantly reduce the temperature difference of wet and dry bulb in the same layer, the average temperature of reduced by 0.41℃ compared to control. The treat- ment of chemical fiber carpet and cotton gauze can reduce energy consumption and improve the appearance quality and benefit. [ Conclusion] The study can provide reference for solving the problems of tobacco leaf uneven yellowed, greened leaf and hanged ash.
