Abstract: The rolling method sheet device for reconstructed tobacco leaves in the laboratory environment was developed, and a study was conducted on the influence of drying parameters on the quality of trial produced thin films in the laboratory environment. The laboratory rolling method sheet device mainly included a rolling module, a thickness control module, a thin sheet stripping module, and a hot air drying module. It had advantages such as adjustable and controllable thin sheet thickness, uniform thickness, low demand for tobacco powder raw materials, small footprint, and short sample preparation time;using an oven to simulate the thin film drying process in a laboratory environment, the influence of drying parameters on the quality of trial produced thin films was studied through the orthogonal test. The results showed that the thickness of the thin sheet prepared by the laboratory rolling method sheet device was 0.1~0.4 mm, with a thickness deviation of ±0.02 mm;the optimal drying process conditions in the laboratory were obtained through orthogonal experiments, that was, when the drying temperature was 95 ℃ and the drying time was 180 seconds, the sensory quality evaluation score of the thin film was the highest.
