Abstract:In order to determine an appropriate size of paper-making reconstituted tobacco,three kinds of tobacco sheets with different sizes were made.Its moisture retention performance and hygroscopicity were analyzed and its cutting performance was evaluated.The processing performance of the pipe tobacco on the silk processing line was studied, and then the pipe tobacco was applied to the cigarette products for comparative analysis of sensory quality. The results showed that there was no significant difference in moisture retention performance and hygroscopicity among three kinds of tobacco sheets, but the water absorption and water loss rate of small-sized tobacco sheets were slightly faster. The whole cutting rate of small-sized tobacco sheets decreased slightly, and the shredding rate increased slightly, but the difference between medium-sized and small-sized tobacco sheets was not obvious. The blending uniformity of finished pipe tobacco blended with small-sized tobacco sheets was better, the filament winding and caking were reduced, the crushing in the processing process was reduced, and the physical index of the cigarette in the rolling process was stable, which could reduce the consumption of pipe tobacco to a certain extent. The cigarette samples blended with small-sized tobacco sheets had lower smoke irritation and improved aroma texture.
