为提高烟叶烘烤质量 ,降低烤房的建造成本和烤烟的烘烤成本 ,研制了燃煤式密集烤房 .对燃煤式密集烤房与气流上升式燃煤烤房进行烟叶烘烤对比试验的结果表明 ,前者建造成本和烘烤成本较后者分别降低 2 7.6 %和1 8.8% ,装烟密度和上等烟比例分别提高 1 73.3%和 1 2 .9% . In order to improve the baking quality of the tobacco leaves, reduce the construction cost of the barn and the baking cost of the flue-cured tobacco, a coal-fired intensive barn was developed. The tobacco-to-bake comparison test was conducted between the coal-fired intensive barn and the air- The results show that the former cost of construction and baking are lower by 22.66% and 18.8% than that of the latter, respectively, and the density of smoke and the proportion of finest smoke are increased by 1 73.3% and 12.2% respectively.
