Abstract:
A comparative test was conducted on a ZJ116B filter cigarette maker to investigate the effects of electronic glue spraying and roller gluing on the quality consistency of slim cigarettes with preperforated tipping paper, in terms of total ventilation rate, draw resistance, mainstream cigarette smoke, moisture content and sensory quality. The results showed that, compared to roller gluing, electronic glue spraying had the following advantages: 1) Superior stability and uniformity of gluing at different machine speeds. 2) At a rated machine speed, the deviations of the mean draw resistance and mean total ventilation rate of cigarettes from the design central values reduced by 94% and 87%, respectively, and the standard deviation of total ventilation rate reduced by 17%, it suggested improved criteria compliance and reduced fluctuation. 3) Greater flexibility in regulating the total ventilation rate, with the control range expanding from 44.2%-46.8% to 36.0%-46.0%. 4) An increase in cigarette moisture content of 0.3 percentage point. 5) An average sensory quality score increase of 1.3 points. 6) There were insignificant differences in the mainstream cigarette smoke indexes between the two gluing methods. In conclusion, electronic glue spraying features higher gluing effectiveness, better consistency of draw resistance, total ventilation rate and sensory quality of slim cigarettes.
