| 目的 开发一种新型烟草薄片成型试制设备，实现薄片自动成型、厚度可调、质量可控。方法 改变钢带和稠浆盒的运动方式;改良传统稠浆法烟草薄片成型工艺，包括剥离剂喷涂工艺、流浆成型工艺、热–风干燥工艺。通过对设备热–风干燥系统的工作过程进行流热耦合分析，并根据结果对热–风干燥系统的结构及参数进行优化，减少薄片在烘干过程中起皱、裂纹等缺陷的产生。结果 开发的稠浆法烟草薄片试制设备可制备0.15～0.3 mm厚度的烟草薄片，且薄片厚度均匀性好。优化热–风干燥系统前，烘干过程中烟草薄片主要区域的温度区间为37.7～59.6 ℃，优化后为50.1～64.2 ℃。结论 该设备减小了烟草薄片成型过程中薄片的尺寸波动，提高了薄片厚度均匀性。优化热–风干燥系统提高了烟草薄片温度分布均匀性，有利于烟草薄片成型质量的提高。 |

| The work aims to develop a new type of trial production equipment for reconstituted tobacco sheet forming to realize automatic sheet forming, adjustable thickness and controllable quality. The movement mode of steel belt and raw material box was changed. The traditional thick paste tobacco sheet forming process was improved, including stripping agent spraying process, slurry forming process and heat air drying process. The fluid-thermal coupling analysis of the working process of the equipment heat air drying system was carried out, and the structure and parameters of the heat air drying system were optimized according to the results, so as to reduce the occurrence of wrinkles, cracks and other defects in the process of sheet drying. The trial production equipment for reconstituted tobacco sheet could produce tobacco sheet with a thickness of 0.15-0.3 mm, and the thickness uniformity of the sheet was good. Before optimization of the heat air drying system, the temperature range of the main area of tobacco sheet in the drying process was 37.7-59.6 ℃, and after optimization, it was 50.1-64.2 ℃. The equipment can reduce the size fluctuation of tobacco sheet in the forming process and improve the thickness uniformity of tobacco sheet. Optimizing the heat air drying system improves the temperature distribution uniformity of tobacco sheet, which is conducive to the improvement of tobacco sheet forming quality. |
