KLD2-3滚筒烘丝机筒壁温度不同控制模式对化学成分的影响

目的]了解KLD2-3滚筒烘丝机烘丝加工过程中烟草化学成分的变化趋势。方法]通过KLD2-3滚筒烘丝机不同控制模式对烘丝后某牌号二类烤烟型叶组配方的烟丝常规化学成分总糖、还原糖、烟碱、氯、钾和常规烟气进行对比分析,应用丙酮萃取、气相色谱仪和气相色谱/质谱联用仪对挥发性、半挥发性烟气香味物质进行研究。结果]顺流模式3种控制方式烘后烟丝的总糖和还原糖测定值均高于逆流模式,逆流模式一段式烟碱含量高于其他控制方式,不同控制方式下烟丝氯、钾、常规烟气、烟气中性香味成分总量比较接近,顺流模式前高后低控制方式下烟丝酸性和碱性香味成分总量高于其他控制方式。结论]研究可为烤烟制丝参数的选择和优化提供数据支持。

Effects of Different Control Systems of KLD2-3 Cylinder Temperature on Chemical Components

Objective] To study the variation trends of tobacco chemical components during cut processing by KLD2-3 cylinder dryer.Method] The effects of different control systems of cylinder on the routine chemical components and mainstream smoke flavors which collected by Cambirdeg filter paper in smoking machine,extracted by acetone,purified by solid phase-extraction column were analyzed.Result] The experiments demonstrated that after drying,the contents of total sugar and reducing sugar of cocurrent mode are super than current mode.The contents of nicotine of one piece cue of counter current mode are super than other control modes.The contents of potassium,chlorine in tobacco and tar,nicotine,carbon monoxide,aroma substances in smoke are alike after drying by different control systems.The total amount of acid aroma substances and alkalescence aroma substances are super than the amount of other control modes.Conclusion] The study provides data support for selection and optimization of flue-cured cut parameters.
