晒棚通风方式对晒黄烟调制效果影响研究

Study on Modulation Effect of Sun-cured Tobacco by Ventilation in Shed

为探索晒烟晒制过程烟叶变色干燥速度和烟叶质量的变化,优化晒烟晒制技术,对设计的晒棚不同通风方式进行研究,结果表明,以晒棚四进风、屋脊排湿的烟叶外观质量好,单叶质量较大,化学成分协调性好,综合表现较优;晒棚两头通风排湿四周封闭的烟叶外观质量较好,单叶质量适中,化学成分较协调,综合表现尚好;而晒棚两侧通风排湿两头封闭的烟叶外观质量稍次,单叶质量较轻,化学成分欠协调,综合表现较差.

In order to study the speed of tobacco leaf color changing,dry speed and quality changing during the sun-cured process to optimize the sun-cured technology,the designed different ventilation sheds are studied.The result showed that the cured tobacco leaf from basking shed with four-side ventilation and ridge damp-extraction has the good quality of outlook,good quality of single piece,good concord in chemicals and better comprehensive representation;the cured tobacco leaf from the shed with two-end ventilation,damp-ex-traction and four-side blocking has better quality of outlook,media quality of single piece,concord chemicals and good comprehensive representation;but the tobacco leaf from the shed with two-side ventilation,damp-extraction and two-end blocking has comparatively bad outlook,light single piece,non-concord chemicals and bad comprehensive representation.
