Core Viewpoint - The introduction of new testing equipment at the Yunnan Tobacco Leaf Re-drying Co., Ltd. Xuanwei Factory marks a significant upgrade in tobacco leaf research, transitioning from traditional methods to a more advanced, multi-dimensional approach that incorporates mechanical and optical properties, thereby enhancing the quality and efficiency of tobacco processing [1][3][11] Group 1: Technological Advancements - The Xuanwei Factory has introduced a texture analyzer and a comprehensive tobacco testing platform, which signifies a shift from basic chemical analysis to a more detailed examination of mechanical characteristics and digital color detection [1][3] - Traditional methods focused on chemical composition and physical structure, but lacked the assessment of mechanical and optical indicators that affect the intrinsic quality of tobacco leaves [3][10] - The new equipment allows for precise measurement of key indicators such as tensile strength, adhesion, penetration strength, shear strength, and leaf stem bonding strength, overcoming the limitations of subjective visual assessments [5][10] Group 2: Data Collaboration - A collaborative database has been established between Xuanwei Factory and Zhejiang Zhongyan, which has enriched the quality characteristics database with over 2,000 sets of mechanical data and 6,000 sets of comprehensive testing data for the 2024 roasting season [7][8] - This data-driven approach enhances the efficiency of formula organization and provides robust support for the potential of "Li Qun" brand raw materials [8][10] Group 3: Process Optimization - The mechanical data obtained from the texture analyzer aids in providing targeted parameter adjustments for the re-drying process, helping to maintain the structural integrity of tobacco leaves and reduce breakage rates [10] - The optical data from the comprehensive testing platform contributes to controlling color stability, ensuring consistent quality in the appearance of finished tobacco products [10][11] - The collaboration between Xuanwei Factory and Zhejiang Zhongyan aims to build a joint research laboratory to further enhance innovation and establish a replicable model for raw material research [10][11]
