  摘要 [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。

  Abstract [Objective] To investigate the effects of the technological process and technological parameters of threshing and threshing on the purity 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 influence on the yield.The cutting head processing rate increased in tobacco leaf,stem ratio,decreased the proportion of leaf debris containing impurity,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.

  打葉复烤作为卷烟生产的第一车间,对烟叶原料质量起着至关重要的作用[1-3]。随着卷烟生产的精细化加工,对烟叶原料质量更加重视,特别是烟叶原料的纯净度,直接影响卷烟配方的使用和品牌的稳定[4]。打叶复烤烟叶纯净度主要指杂物和叶中含梗率2个方面,为此卷烟工业对打叶复烤烟叶原料质量倍加关注,对打叶复烤企业也提出了更高的要求。笔者研究了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,旨在确立较为适宜的加工路径和工艺参数,以提升烟叶原料的纯净化水平。
  1 材料与方法
  1.1 材料 原料:2016年皖南C3F烟叶,2016年四川凉山C3FA烟叶,2016年云南昭通C3FA烟叶,2016年四川凉山C2FA烟叶。主要仪器:264型叶中含梗率检测仪;QCTS-1260型叶片振动分选机;AutoAnalyzer3连续流动分析仪。
  1.2 方法 将皖南C3F试验原料平均分成2部分,一部分进行切把头处理,把头烟叶在把头处理线加工,打后的烟叶在烤前与叶身处理后烟叶汇总一起进行复烤、装箱等处理;另一部分按照正常生产工艺路径处理。比较2种方式对成品片烟杂物、经济指标、叶片结构[5-6]的影响。
  将四川凉山C3FA试验原料平均分成2部分,一部分按照正常工艺路径要求加工;将另一部分风选除杂烟叶和挑选后的碎叶进行分离处理,其他按照正常工艺要求加工;分析风选除杂烟叶和挑选后的碎叶叶片结构、常规化学成分[7-11]的同时,比较2种方式对成品片烟杂物、经济指标的影响。
