打浆度、壳聚糖和瓜尔胶对造纸法再造烟叶切丝损耗的影响

Effects of Beating Degree of Pulp,Chitosan and Guar Gum on Cutting Loss of Paper-process Reconstituted Tobacco

【目的】为提高造纸法再造烟叶在卷烟制丝加工过程中的有效利用率,减少制丝线上产生的粉尘。【方法】分别从浆料的打浆度、配方中加入壳聚糖和瓜尔胶两种阳离子吸附剂三个方面,对再造烟叶的切丝损耗进行考察。【结果】当烟草浆料打浆度由35°SR分别提高至45、55、65和75°SR,再造烟叶的切丝损耗分别降低2.07%、2.33%、3.69%和4.32%;在浆料中添加壳聚糖后,再造烟叶的切丝损耗无明显影响,而添加瓜尔胶后,再造烟叶的切丝损耗都有不同程度的降低,其中添加0.2%的瓜尔胶降幅最大,达到1.08%;在涂布液中添加壳聚糖和瓜尔胶后,再造烟叶的切丝损耗都有一定程度的降低,当二者添加比例为0.3%时降幅最大,分别为2.78%和3.50%。【结论】调节浆料打浆度、在浆料或涂布液中加入适量的壳聚糖或瓜尔胶,可以降低造纸法再造烟叶的切丝损耗,提高卷烟制丝过程中的有效利用率并改善生产环境卫生。

[Purpose]In order to improve the effective utilization rate of paper-process reconstituted tobacco in the process of cigarette processing and to reduce the dust on the primary processing line.[Method]The cutting loss of reconstituted tobacco was investigated from the beating degree of tobacco pulp,adding chitosan and guar gum to product formula,respectively.[Result]The cutting loss of reconstituted tobacco was decreased by 2.07%,2.33%,3.69%and 4.32%,when the beating degree of tobacco pulp increased from 35°SR to 45,55,65 and 75°SR,respectively;the cutting loss of reconstituted tobacco had no significant effect after adding chitosan in the pulp,but it was reduced to some extent after adding guar gum,declined by 1.08%when its dosage was 0.2%;the cutting loss of reconstituted tobacco was decreased to some extent when the chitosan and guar gum were added into the coating solution,declined by 2.78%and 3.50%respectively when the dosage was 0.3%.[Conclusion]Adjusting the beating degree of the pulp and adding suitable amount of chitosan or guar gum to the pulp or coating solution can reduce the cutting loss of reconstituted tobacco,and improve the effective utilization rate and the production environment in the process of cigarette processing.
