  Abstract [Objective] In order to control the quality of tobacco leaf cutting, the key indexes were studied during the cutting.[Method]The permissible deviation and qualified rate of both the cutting distance and the cutting angle were studied on C3F grade tobacco leaf of Fangcheng County Nanyang, Henan Province. Sensory taste was the main mean to evaluate the tobacco quality.The influences of
  Permissible deviation of the cutting distance,Qualified rate of the cutting distance,permissible deviation of the cutting angle on the quality of cut tobacco leaf were observed by smoking evaluation together with conventional chemical analysis.[Result] Results show that while the permissible deviation of the cutting distance was within 1 cm, the qualified rate of the cutting distance was above 90%, the permissible deviation of the cutting angle was within 20°, the qualified rate of the cutting angle was above 85%, the quality of leaf cutting was stable. Therefore, the four indexes can be used as the key indexes of tobacco leaf cutting in quality control.[Conclusion] The research can provide necessary technical support for the popularization and application of tobacco cutting technology.

  烟叶分切后再加工、使用,不仅可以提高烟叶使用价值,增强卷烟企业原料保障能力,还能加快打叶复烤企业的技术进步,提高片烟产品质量。针对单片烟叶质量变化规律、烟叶分切方法确定、烟叶分切设备开发,国内多家机构都进行了深入研究。单片烤烟不同区位烟片的常规化学成分、致香成分、评吸质量存在较大差异,其变化具有一定的规律性,叶中部分烟叶品质相对较好,叶尖部次之,而叶基部分相对较差[1-5]。不同烟叶内在质量与外观质量一致即“内外一致”的原则对单片烟叶不同区位同样适用。烟叶外观质量明显变化的地方内在质量变化也较为明显,故烟叶最佳分切位置可通过外观质量确定[6-7]。然而,对于影响烟叶分切质量的其他控制指标尚缺乏系统研究,影响了烟叶分切技术的推广应用。分切试验和生产实际验证结果表明,切距、切角一致的烟片,外观质量、常规化学成分、评吸质量一致,能全面反映分切产品的质量状况。因此切距允差、切角均可作为分切质量控制的关键指标。
