在烘烤过程中,密集烤房内部不同位点的风速之间密切又复杂.为确定风速指标间的关系,测定了密集烤房内405个风速值,对15个风速指标进行了灰色关联聚类分析.结果表明:当聚类临界值为0.8时,15个风速指标可被聚为2类;当聚类临界值为0.7时,15个风速指标可被聚为1类.通过分析,密集烤房内部同一平面不同位点的风速差异较小,可视为均匀一致,密集烤房能够保证装烟室同一层烟叶整体上均处于同样的变色和干燥环境下,从而能够在理论上保证其烟叶相同的烘烤质量.
During the process of baking, the wind speeds at different sites in intensive barn were close and complicated.In order to determine the relationship between wind speed indexes, the 405 wind speed values in intensive barn were measured, and the gray index of 15 wind speed indexes The results show that when the critical value of clustering is 0.8, 15 wind speed indexes can be grouped into 2 categories and 15 wind speed indexes can be grouped into 1 categories when the clustering threshold value is 0.7.According to the analysis, The difference in wind speed at different sites in the same room in the barn is smaller and can be regarded as uniform. The intensive barn can ensure that the same layer of tobacco leaves in the same room is under the same discoloration and dry conditions, so as to theoretically ensure that The same baking quality of tobacco leaves.
