摘　　要：为降低烟叶烘烤成本，实现烟叶工厂化烘烤，在步进式烤房的基础上研制了8隧道30m流水线烤房。该烤房由装烟区、准备区、烤烟区、降温区和卸烟区5部分组成，其中烤烟区依据干燥要求划分为6个区段，并分别设定温度和相对湿度范围。对烘烤过程中各区段烘烤环境变化进行监测，并对流水线烤房与普通密集烤房的烘烤效果进行对比分析。结果表明：流水线烤房的运行时间为134～146h，温湿度以及风速的变化均能够满足烟叶烘烤需求；与密集烤房相比，流水线烤房烟叶的鲜干比略有减小，烤后烟叶的橘色烟比例显著增加；中部叶与上部叶的均价分别提高1136和1．13元／kg，提高幅度6．04％和5．08％；烘烤工效分别提高23．1和25．8kg／（工·日），烤烟能耗分别减少0．18和0．07元／kg干烟叶。流水线烤房实现了热量的多级高效利用，能够满足烟叶烘烤过程中各时期的需求。In order to reduce the cost of tobacco flue-curing, an 8-tunnel 30 m continuous flue-curing barn was developed on the basis of stepping flue-curing barn. The developed barn was composed of tobacco loading, preparing, flue-curing, cooling and tobacco unloading sections. The flue-curing section was divided into 6 sub-sections dependent on curing requirements, and the temperature and relative humidity in each sub-section were separately set and monitored during curing. The curing results were compared with conventional bulk barn. The results showed that the running time of continuous flue-curing barn was in the range of 134-146 h, and the variations of temperature, relative humidity and air velocity in the barn met the curing requirements. Comparing with bulk curing barn, the fresh/dry tobacco weight ratio decreased slightly, the proportion of orange leaves significantly increased; the average prices of middle leaves and upper leaves raised by 1.36 RMB yuan/kg （6.04%） and 1.13 RMB yuan/kg （5.08%）, the curing efficiencies promoted by 23.1 and 25.8 kg/day per worker, the energy consumption reduced by 0.18 and 0.07 RMB yuan/kg dry leaves, respectively. Continuous flue-curing barn achieves efficient heat utilization and satisfies the requirements in each curing stage.
