小试加香加料误差分析

Analysis of Error in Cigarette Flavoring and Casing Experiments

为提高卷烟小试加香加料的准确性,进行了降低小试加香加料误差试验。结果表明:烟丝用量、添加比例、香精香料的密度和添加时烟丝翻动的次数都会带来不同程度的误差,加香和加料误差分别为8.24%～16.00%和2.56%～7.11%。提出了一种新的小试加香加料方法———天平示量法。即将烟丝放在天平上进行添加,直至天平上显示香精香料理论用量。这种方法可使小试加香加料精度达到99.0%以上,甚至可以做到零误差,完全能够达到卷烟生产工艺要求。

Experiments on reduction of error in cigarette flavoring and casing were conducted. The results showed that the experimental error in flavoring and casing caused by the amount of cut tobacco, rate and density of added flavoring and casing, and the tumbles of cut tobacco during flavoring and casing, was from 8.24% to 16.00% and 2.56% to 7.11%, respectively. A new method for cigarette flavoring and casing experiment, metering on a balance, was developed. Namely, flavoring or casing was added to cut tobacco on a balance until the desirable weight was reached. The accuracy of the method was over 99%, even up to 100%.
