试验于2016年在湖南省耒阳市马水镇烟叶烘烤工场进行。试验共设6个处理,分别是:T1.空气能热泵热水式密集烤房,T2.空气能热泵热风上升式密集烤房,T3.空气能热泵热风下降式密集烤房,T4.生物质燃烧供热式密集烤房,T5.太阳能热风式密集烤房,T6.燃煤式密集烤房(CK)。试验结果表明:T2、T3烟叶烘烤效果最好,不但防止了对环境的污染,而且烘烤成本还低于燃煤式密集烤房;T1由于热交换率低,热风循环欠顺畅,烤房升温排湿有一定难度,造成烘烤历时拖长,烘烤成本高于燃煤式密集烤房;T4能完成烟叶烘烤过程,烤后烟叶质量也不差,但是,烘烤成本不很稳定,烤下部叶低于燃煤式密集烤房,烤中、上部叶高于燃煤式密集烤房,并且都高于空气源热泵密集烤房;T5烟叶烘烤的节能减排效果受天气状况影响较大,烘烤期间,晴天多,效果明显,阴雨天多,则效果不明显。
The experiment was carried out in 2016 at the tobacco drying factory in Ma Shui Town, Leiyang City, Hunan Province. A total of six trials were processed, namely: T1. Air heat pump hot water intensive barn, T2. Air heat pump hot air rising intensive barn, T3. Air heat pump hot air descending intensive barn, T4. Biomass Combustion heating intensive barn, T5. Solar hot air intensive barn, T6. Coal-fired intensive barn (CK). The results showed that: T2 and T3 tobacco had the best baking effect, which not only prevented the pollution to the environment, but also the baking cost was lower than that of the coal-burning intensive barn; T1 had low heat exchange rate, Heating temperature and humidity have a certain degree of difficulty, resulting in prolonged roasting, baking costs higher than the coal-fired intensive barn; T4 can complete the process of baking tobacco, roasted tobacco quality is not bad, however, the baking cost is not very stable , Roasted lower leaves lower than the coal-fired intensive barn, bake, the upper leaf higher than the coal-fired intensive barn, and are higher than the air source heat pump-intensive barn; T5 tobacco baking energy-saving emission reduction by the weather conditions A greater impact, during baking, more sunny, the effect is obvious, more rainy days, the effect is not obvious.
