打叶复烤不同工艺路径及工艺参数对烟叶纯净度等指标的影响

Effects of Different Processing Paths and Technological Parameters on Purity of Tobacco Leaves after Threshing and Redrying

[目的]研究打叶复烤工艺路径及工艺参数对烟叶纯净度等指标的影响,最大限度地提升打叶复烤烟叶纯净度。[方法]以皖南C3F、凉山C3FA烟叶为试验载体,开展了打叶复烤不同工艺路径、工艺参数对烟叶纯净度影响试验。[结果]在试验条件下,不同工艺路径和不同工艺参数对出片率基本无影响,切把头处理烟叶中片率提高,叶中含梗率、杂物比例下降,风选除杂烟叶和挑选后碎叶分离处理后杂物比例下降,切片刀数由1刀调整为2刀烟叶中片率提高,随着整线工艺流量的下降叶中含梗率略有下降,风选除杂风机频率过大过小均不利于杂物的剔除,宜设计合理的参数值。[结论]打叶复烤工艺路径及工艺参数均对烟叶纯净度有一定程度影响。

[Objective] To investigate the effects of the technological process and technological parameters of threshing and threshing on the puri-ty of tobacco leaves,so as to maximize the purity of threshing and curing tobacco leaves.[ Method] The effects of different processing paths and technological parameters on the purity of tobacco leaves were studied by using the C3F leaves of C3FA in southern Anhui Province and Liangshan tobacco leaves as experimental carriers.[Result] Under the test condition,the different process path and different process parameters had no in-fluence on the yield.The cutting head processing rate increased in tobacco leaf,stem ratio,decreased the proportion of leaf debris containing impu-rity,winnowing tobacco and selected leaf separation after treatment decreased the proportion of debris,knife number from 1 to 2 when the knife knife adjustment in tobacco leaf rate increase.With the stem ratio decreased slightly the whole line process flow rate decreased in the leaves,the impurity winnowing fan frequency which was too large or too small were not conducive to the elimination of debris,should design reasonable value parameters [ Conclusion] Both the technological path and technological parameters of threshing and redrying have a certain influence on the purity of tobacco leaves.
