安徽农学通报2023年05期农产品质量·检测·加工·销售基于均质化加工需求的原烟精选研究与应用王树林李志伟兰刚徐振鹏杨闯向盼来曲平治*(四川中烟工业有限责任公司,四川成都610066)摘要随着烟草行业均质化加工的不断推进,卷烟产品对打叶复烤均质化加工提出了更高要求。为保障烟叶原料的稳定性,同时为娇子(宽窄)系列产品提供纯净化的原料,本文研究了原烟精选对均质化加工效果的影响,采取落地精选的方式在复烤加工前对原烟进行了二次分选,对精选前后烟叶的等级合格率、青杂光烟含量、杂物含量进行了对比分析,并对打叶复烤后的成品片烟进行均质化加工效果评价。结果表明:精选有效剔除了原烟中的混部位、混色、混级烟叶,烟叶等级合格率提高到87.65%以上,明显降低了烟叶中的非烟物质含量,烟叶的内在质量明显提高,成品片烟烟碱CV值、糖碱比CV值、水分CV值分别为3.12%、4.81%、1.84%。原烟精选实现了打叶复烤成品片烟的均质化全过程闭环管理,成为打叶复烤均质化加工的重要环节,使均质化复烤加工水平进一步提升,值得推广应用。关键词烤烟;精选;等级质量;打叶复烤;均质化中图分类号S572文献标识号A文章编号1007-7731(2023)05-0125-05ResearchandApplicationoftheSelectionMethodofFlue-curedTobaccoBasedonHomogenizationProcessingNeedsWANGShulinLIZhiweiLANGangXUZhenpengYANGChuangXIANGPanlaiQUPingzhi*(ChinaTobaccoSichuanIndustrialCo.Ltd.,ChengduSichuan610066)AbstractThegradequalityofflue-curedtobaccowaslowerduringindustrycommercehandoveranditgoneagainstthestabilityandsafetyofproductformula.Inordertosolvetheproblems,theflue-curedtobaccowascarefullychosenbeforethreshingandredrying.Thequalifyingrate,greenandvariegatedleaves,miscellany,smokingquality,homogenizationprocessing,wereanalyzedinthispaper.Theresultsshowedthatthegreenandvariegatedleaves,miscellany,wereallchosen.Thequalifyingratewasimprovedto87.65%.Themiscellanyduringtheleaveswasless.Thesmokingqualitywasalsoimproved.ThenicotineCVwas3.12%,thesugar-nicotineratioCVwas4.81%andthewaterCVwas1.84%.Refinedselectionbecomedanimportantpartofhomogenizationprocessingforthreshingandredryingrefinedselectionmadeclosed-loopmanagementforthreshingandredrying.Alltheseplayedanimportantroleinimprovingthehomo...
