摘要:本研究以平衡含水率表征稠浆法烟草薄片的吸湿性,通过控制变量法探究了外加纤维打浆度和纤维种类、烟粉粒径以及填料种类对薄片吸湿性的影响,并优化稠浆法烟芯薄片的制备工艺。研究结果表明,外加纤维打浆度、纤维种类以及烟粉粒径对烟草薄片吸湿性影响较小；对比5种无机填料,发现添加膨润土能有效降低烟草薄片平衡含水率,改善吸湿性；当稠浆中膨润土的质量浓度为0~2%时,随着膨润土用量的增加,烟草薄片的平衡含水率降低,当膨润土在稠浆中的质量浓度为1.5%时,烟草薄片在50%、60%和70%的湿度下其平衡含水率较原片分别降低了16.7%、15.5%和13.5%,制备的卷烟在发烟量、烟香方面与原片相近。

Abstract:This study characterized the moisture absorption of slurry-type reconstituted tobacco flakes using the equilibrium moisture content, and explored the effects of added fiber beating degree, fiber type, tobacco powder particle size, and inorganic filler type on the moisture absorption of the tobacco sheet using the method of controlled variables. The study also optimized the preparation process of slurry-type reconstituted tobacco flakes. The results showed that the effects of added fiber beating degree, fiber type, and tobacco powder particle size on the moisture absorption of tobacco sheet were small. Among the 5 inorganic fillers, adding bentonite was found to be effective in reducing the equilibrium moisture content of tobacco sheet and improving its moisture absorption. As the concentration of bentonite in the thick paste increased from 0% to 2%, the equilibrium moisture content of the tobacco sheet decreased. When the concentration of bentonite in the thick paste was 1.5%, the equilibrium moisture content of the tobacco sheet at 50%, 60%, and 70% humidity was 16.7%, 15.5%, and 13.5% lower than that of the original sheet, respectively. The cigarette made from the sheet had similar burning rate and fragrance to the original cigarette.
