摘　　要：浙江中烟工业有限责任公司下设两个生产基地,分别配备COMAS逆流式烘丝机和HAUNI顺流式烘丝机。为了克服烘丝机设备和叶丝干燥工艺差异、统一制丝生产工艺、实现不同产地产品的同质化,在对比分析了两种烘丝机工作原理和控制方式的基础上,对COMAS烘丝机进行了整体改造。内容包括:热风流向变为顺流式;风机增加变频调速功能,调节热风流量,减少能源消耗;采用HAUNI方式的热风温度与筒壁温度控制方式;在出料端安装负压传感器保持烘丝机进出风量平衡。改造后的COMAS烘丝机的热风流向、控制方式趋近于HAUNI顺流式烘丝机,各项工艺和物理指标均达到或优于改造前水平,烘丝冷却后含水率控制稳定,含水率偏差控制在0.18%以内,有效控制了干头干尾烟丝量,且减少了蒸汽消耗。COMAS counter current cut tobacco dryer and HAUNI cocurrent cut tobacco dryer were separately used in two manufacturing facilities of China Tobacco Zhejiang Industrial Limited Corporation. In order to unify processing technology and quality of products, the working principles and control systems of the two dryers were compared and COMAS dryer was rebuilt as following： changing hot-air direction from counter current into cocurrent; adding a frequency conversion speed regulator to hot-air fan motor to adjust air volume and reduce energy consumption ; the temperatures of hot-air and cylinder wall being controlled in the same way as that in HAUNI dryer; installing negative pressure sensor at output end to balance the input and output air flow. The rebuilt COMAS dryer showed better performance. The moisture content in dried cut tobacco after cooling was stable, and its deviation was under 0. 18%. In addition, the amount of over-dried cut tobacco during start and finish of drying operation was effectively controlled and steam consumption was also reduced.
