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.
