Stem Expansion Equipment
Improved Physical Properties: Microwave radiation rapidly expands stem fibers, forming a porous structure, which significantly increases its filling capacity and absorbency in stem-based products. Superior Sensory Quality: The rapid heating induces the Maillard reaction which lowers woody smell and releases distinct aromatic compounds, better meeting cigarette sensory quality requirements. Cut Expanded Stems: Expanded stems are cut into shreds, which are similar with cut tobacco lamina, ideal for regular, medium and slim cigarettes production.
Primary Processing Production Line
Serving as an essential part of cigarette production, primary production line would employs automated procedures to process lamina and stem into qualified shreds. The line is divided into four sections: lamina process cut lamina process cut stem process mixing and blending process
AI Tobacco Photoelectric Sorter
The AI Tobacco Photoelectric Sorter is an integrated tobacco impurity removal system. It employs a conveying mechanism combining high-speed belt conveyance with air pressure support, utilizing spectral imaging and AI-powered deep learning for impurity identification. This system effectively removes non-tobacco foreign materials, ultimately supplying clean and high-quality tobacco lamina for subsequent processing stages. Black Background Imaging Technology: Combined with focused lighting and AI algorithms to counteract light source attenuation, ensuring excellent long-term equipment stability. Parameters require maintenance only every 3–6 months. Advanced AI Image Recognition Technology: Utilizes parallel processing of AI algorithms and color sorting algorithms, significantly improving the detection rate for foreign matter with colors similar to tobacco, leading to a substantial increase in the amount of foreign matter removed. Powerful AI Computing Capability: Each image processing unit is equipped with an FPGA and a GPU, with GPU computing power reaching up to 200 TOPS, providing robust hardware support for AI model operations. Warning Function for Specific NTRMs (non-tobacco rejected matters): The system classifies and calculates out the images of NTRMs, providing operators with early warnings for these specific types.
Threshing and Redrying Production Line
The Tobacco Threshing and Redrying Process separates lamina from stems through threshing, followed by redrying that reduces lamina moisture to 11%–13%, thereby supplying high-quality raw materials for subsequent production stages. The production line consists of the following components: Preprocessing: Vacuum conditioning, bundle opening, tip cutting, conditioning, and impurity removal. Separation: Tobacco leaves are divided into lamina, scraps, and stems. Redrying: Lamina, scraps, and stems undergo redrying treatment. Baler: Lamina is compressed into standardized boxes with specified dimensions and density. Auxiliary Equipment: Includes dedicated dust removal and electronic control systems.
