风机配置对热风循环烤房性能和烟叶烘烤质量的影响

Effects of Fan Power on Characteristics of Hot-air Circulation in Barn and Cured Leaf Quality of Tobacco

摘要: 比较了4种风机（60W、90W、120W和150W）对热风循环烤房水平向和垂直向温度、风速和烟叶烘烤质量的差异。结果表明，2.7 ｍ× 3.3 ｍ小型5层烤房，装烟密度为竿距25 cm的情况下配置90~120Ｗ的风机，能显著提高热风循环烤房性能和改善烟叶烘烤质量。

Abstract: Effects of 4 kinds of hot-air circulation fans with power (60W, 90W, 120W and 150W) on the horizontal and vertical temperature, the wind speed in the barn, and the cured leaf quality were compared. The testing barn was 2.7ｍ×3.3ｍ with the space separated into five floors and a clearance of 25cm between two rods with leaf plait. The results showed that hot-air circulation with the fan of 90~120W has significantly effects on increasing characteristics of hot-air circulation in the barn and improving the cured leaf quality of tobacco.
