Effects of Different Drying Methods on Reconstituted Tobacco Mainstream Smoke and Combustion Temperature

Purpose The objective of this study was to set the drying process conditions to reduce CO release and increase CO/tar ratio in mainstream smoke of reconstituted tobacco.Method The effects of different drying temperature on reconstituted tobacco mainstream smoke, burning temperature and temperature distribution were studied in this paper.Results (1) As the drying temperature reduced, the reconstituted tobacco CO release and the ratio of CO to tar were reduced.(2) With the drying temperature decreasing, the peak temperature, average peak temperature, smoking average temperature and smoldering mean temperature of different drying methods reconstituted tobacco showed a downtrend, and the effects of drying temperature on the peak temperature, average peak temperature were significant.(3) The drying method effecting on reconstituted tobacco combustion temperature distribution were obvious:with the drying temperature reducing, the proportion of 150℃ to 400℃ combustion temperature period showed a downtrend; the proportion of 401℃ to 850℃ combustion temperature period showed a upward trend, while the proportion of above 850℃ combustion temperature period shows a downtrend trend.Conclusion Reducing drying temperature could improve reconstituted tobacco product smoke and combustion characteristics.
