包式固定堆积装烟方式烘烤效果研究

为验证密集烤房包式固定堆积装烟烘烤效果，以云烟97中、上部叶为材料，对烟夹装烟和包式固定堆积两种装烟方式装烟量、用工、烘烤耗能成本及烤后烟叶物理性状、化学成分、外观质量、经济性状、感官质量进行比较分析。结果表明，包式固定堆积装烟量及密度比烟夹装烟提高45.70%~49.50%，编装烟和卸解烟用时缩短，每千克干烟烘烤用工及耗能综合成本下降0.46~0.50元。烤后烟叶平衡含水率提高0.15~0.30百分点（p<0.05），总糖含量提高1.40~2.13百分点（p<0.05），油分、色度均得到显著改善。包式固定堆积装烟量大、减工效果明显、烤后烟质量较好，是一种值得示范推广的烟叶烘烤装烟方式。

Baking Effects of Tobacco Leaves Loaded with the Pack-Style Mode in Bulk Curing Barn

In order to study the baking effect of the pack-style mode (tobacco fixed and stacked in packs) of bulk curing barn, the middle and upper leaves of Yunyan 97 were used to analyze tobacco loading, labor, energy consumption cost, physical properties, chemical composition, apparent quality, economic properties and sensory quality of flue-cured tobacco leaves, taking the clamp mode (tobacco held in the clamps) as the control. The results showed that the quantity and density of pack-style mode increased by 45.70%-49.50% compared with that of the clamp mode, the time of loading and unloading was shortened and the comprehensive cost of labor and energy consumption per kg dry tobacco was decreased by 0.46-0.50 yuan. The balanced moisture content of flue-cured tobacco leaves was increased by 0.15-0.30 percentage points(p<0.05), the total sugar content was increased by 1.40-2.13 percentage points(p<0.05), and the oil and color intensity were significantly improved. The results showed that the pack-style mode had the advantages of larger amount of tobacco loading, obvious work reduction effect and good quality of cured tobacco, which was worthy of demonstration and application.
