为制订打叶复烤非烟物质控制技术规程,本试验对8家复烤企业设备除杂、人工除杂两种方式剔除的非烟物质进行数量和类别的分析。结果表明,设备、人工剔除的非烟物质重量占投料量的比例分别为7.11×10-6和8.09×10-6,金属探测仪、光电除杂机、风分除杂机对一类非烟物质的剔除占比相对较高,光电除杂剔后输送带、铺叶工位、烟叶挑选和叶片复烤后工位剔除一类非烟物质占比相对较高。累计剔除的非烟物质主要为二类非烟物质,占比95.56%。打叶复烤宜配置筛砂机、风分除杂机、麻丝带(辊)、金属探测仪、麻丝剔除机和光电除杂机等除杂设备,宜在烟叶挑选、铺叶台、精选台、风分除杂剔后输送带、光电除杂剔后输送带、打叶工序段叶片和烟梗汇总输送带和打叶工序段筛分振筛处、叶片复烤后等工序进行人工剔除非烟物质。综上,一类非烟物质控制关键点应放在烟叶挑选、铺叶台、金属探测、风分除杂和光电除杂等工序,人工剔除非烟物质控制重点应放在打叶工序之前。

To formulate technical regulation for controlling non-tobacco substances during threshing and rebaking, the quantity and category of non-tobacco substances removed by equipment and manual removal in 8 rebaking enterprises were analyzed. The results showed that the proportion of non-tobacco substances weight to the feed volume removed by equipment and manual removal were 7.11×10-6 and 8.09×10-6 respectively. The proportion of non-tobacco substances removed by metal detector, photoelectric decontamination machine, and air separation decontamination machine was relatively high. The proportion of Class Ι non-tobacco substances removed by photoelectric decontamination machine was relatively high in conveyor belt, leaf laying station, tobacco picking station and leaf reheating station. The non-tobacco substances accumulatively removed were mainly Class II non-tobacco substances, accounting for 95.56%. It is advisable to install sand screening machine, air separation decontamination machine, hemp ribbon (roller), metal detector, hemp silk stripping machine and photoelectric decontamination machine, etc. Manual removal of non-tobacco substances stations should be carried out in the tobacco selection, leaf laying, selection, conveyor belt after air separation and impurity removal, conveyor belt after photoelectric impurity removal, conveyor belt for leaf and tobacco stem collection in the leaf beating process, screening and vibrating screen in the leaf beating process, and after leaf reroasting. In summary, the key points of Class Ι of non-tobacco substances control should be placed in the tobacco selection, leaf laying table, metal detection, wind separation and photoelectric impurity removal processes, and the control focus of manual selection of non-tobacco substances should be placed before the leaf beating process.
