提高梗丝膨胀率的有效方法

The technological research of increasing the expansive rate of the stalk silk

利用调湿通道式高温高湿法对梗丝进行膨胀 ,这是我国卷烟行业中普遍采用的方法 ,但其膨胀率一般只能达到百分之二十几。通过分析和实践表明 ,只要采用合理的工艺流程 ,改进和加强加温、加湿、膨梗丝通道、流量控制、切梗丝机、烘梗丝机等几个主要设备和工艺 ,把握预加温加湿、切梗、梗丝膨胀、烘梗丝等几个重点工序 ,就可以使梗丝膨胀率稳定在 4 5%左右 ,经济效益显著。

One of technological process for expansion of the stalk silks is the way of high temperature and high humidity by utilizing the passage type of adjusting humidness.It is wildly used in the manufacture of the cigarette.The problem of this way is lower expansive rate of the stalk silk.Our new technological process improves the expansive rate from 20 per cent to 45 per cent.We have achieved obvious economy benefits with this new way.This new technological process includes improving some equipments and technology.
