摘要:基于稠浆法烟草薄片,研究薄片含水率与环境湿度及平衡时间的相关性,探讨膨润土和滑石粉等无机填料添加量对薄片吸湿性能及物理指标的影响。研究结果表明,薄片初始含水率越高,在后续更高湿度下平衡2h的含水率越高,薄片平衡2h的含水率一定程度上可以反映薄片的吸湿率。薄片中添加膨润土或滑石粉均有利于降低薄片的吸湿性,适宜的添加量为质量浓度2.0%,薄片的紧度和抗张强度均满足后续加工需求。从感官质量评价结果来看,滑石粉是一种较理想的填料。

Abstract:Based on the tobacco sheet prepared by thick pulp method, the correlation between the moisture content of the sheet and environmental humidity and equilibrium time was studied, and the influence of inorganic fillers such as bentonite and talc powder on the moisture absorption performance and physical indicators of the sheet were explored. The experimental results show that the higher the initial moisture content of the sheet, the higher the moisture content of the balance 2 hours under the subsequent higher humidity. The moisture content of the sheet for balancing 2 hours could reflect the moisture adsorption rate of the sheet to some extent. Adding bentonite or talc powder to the sheet was beneficial for reducing its moisture absorption characteristic. The appropriate amount of addition was 2.0% by mass concentration, and the tightness and tensile strength of the sheet meet the subsequent processing requirements. From the sensory quality evaluation results, talc powder was ideal filler.
