1、烤烟烟夹烘烤过程中叶间隙风速的研究摘要:为丫解散叶烘烤过程中烟叶不同位点的叶间隙风速的变化以及影响风速变化的主要因素,利用风速仪对中棚烟叶距离加热室1,3,5,7m处的8个位点的叶间隙风速进行实时监测,同时记录烤房的干湿球温度,并于烘烤开始后每隔4h取1次样,测定叶片与叶脉的含水率。结果表明:烘烤过程中8个位点叶间隙风速差异较大,丼中6号位点的风速始终处于较低水平;不同烘烤阶段各位点风速的变化大体表现为先降后升的趋势;湿球温度在整个烘烤过程中对叶间隙风速的影响最大,直接通径系数为-0.9749,叶片含水率对叶间
2、隙风速也有较大影响,直接通径系数为0.4044。在烘烤中可以通过控制烟叶含水率与湿球温度等来调控叶间隙风速的变化,并进一步改善烟叶质量。本文采集自网络,本站发布的论文均是优质论文,供学习和研究使用,文中立场与本网站无关,版权和著作权归原作者所有,如有不愿意被转载的情况,请通知我们删除己转载的信息,如果需要分享,请保留本段说明。关键词:散叶烘烤;叶间隙风速;烘烤阶段;通径分析中图分类号:S573文献标识码AD0I编码:10.3969/j.issn.1006-6500.2017.07.023ResearchonWi
