13工艺技术《食品工业》2023年第44卷第1期梗签废料中可用烟丝回收工艺优化蔡艳1,孙常荣1,张荣亚1,2*,王丁1,杨志强1,曾敏东11.四川中烟工业有限责任公司成都卷烟厂(成都610066);2.四川中烟工业有限责任公司技术中心(成都610066)摘要在卷烟生产过程中,由于切丝并条等各种原因造成粘连烟丝。由于粘连烟丝与梗签密度较为接近,在制丝风选和卷烟机剔梗过程中会被当作梗签剔除,造成严重浪费。虽然卷烟机有在线分离梗签回收烟丝装置,但主要基于风分原理,在线回收烟丝效果不好。试验创新应用筛分、滚筒润丝、蒸汽膨胀、烘丝、风选、结构筛分提取卷烟机剔除梗签中所含烟丝,解决结团、粘连烟丝被风选设备和剔梗设备误剔除造成的烟丝原料浪费问题,提高梗签烟丝回收率和纯净度,实现资源化处理烟草生产废弃物及设备资源化再利用,回收烟丝可为企业节约成本875万元/年。关键词粘连烟丝;卷烟机剔梗废料;梗签;烟丝;风选;蒸汽膨胀TheOptimizationoftheProcessforRecyclingTobaccofromTobaccoStemWasteCAIYan1,SUNChangrong1,ZHANGRongya1,2*,WANGDing1,YANGZhiqiang1,ZENGMindong11.ChengduCigaretteFactory,ChinaTobaccoSichuanIndustryCo.,Ltd.(Chengdu610066);2.TechnologyCenterofChinaTobaccoSichuanIndustryCo.,Ltd.(Chengdu610066)AbstractIntheproductionprocessofcigarettes,usabletobaccothatstickstogetherisproducedduetovariousreasonssuchasshredding.Becausetheweightoftheadhesivetobaccoandthetobaccostemisrelativelyclose,adhesivetobaccowillbetreatedastobaccostemandremovedfromtheproductionlineaswastematerialduringtheprocessoftobaccowindselectionandcigarettestemremoval,resultinginseriouswaste.Althoughthecurrentcigarettemachinehasonlinetobaccostemseparationdevicetorecovertobaccostem,duetothelimitedspaceandthedefectoftheairseparationprinciple,theeffectofonlinetobaccorecoveryisnotverygood.Theapplicationofscreening,steamexpansion,tobaccodrying,airseparation,structuralscreeningextractioncigarettemachineisinnovatedtoremovethetobaccocontainedinthetobaccostemwaste,tosolvetheproblemoftobaccorawmaterialwastecausedbythefalseremovalofthetobaccoairseparationequipmentandthecigarettestemremovalequipment,toimprovetherecoveryrateandpurityofthetobacco,andtorealizetheresourcetreatmento...
