Tobacco Primary Processing Engineering Data

1. General Overview Product: Cigarette cut tobacco (represented by the code Brand A in the dataset). Data Scale: A total of 1,051 production batch records, comprising 64 feature variables. Time Span: January 3, 2024, to October 14, 2024. Data Granularity: The minimum unit is the "Batch Number" (e.g., 240102HSXY##04), with each row representing a complete production batch. 2. Core Production Processes and Features Following the actual physical flow of tobacco processing, the data covers the entire chain from raw material treatment to final flavoring. It mainly includes the following 8 key processing stages: Processing Stage Example of Key Monitored Parameters Business Significance 1. Loosening & Rehumidification Process flow rate, ambient temperature/humidity, water addition coefficient, steam flow rate Pretreatment of tobacco leaves to increase temperature and moisture, enhancing toughness. 2. Pre-mixing Storage duration, inlet moisture content Mixing and temporary storage of tobacco leaves to balance moisture. 3. Leaf Casing (Flavoring) Casing liquid temperature, HT steam valve opening, casing ratio Application of flavorings and sugar solutions to improve taste. 4. Leaf Storage Storage duration, ambient temperature/humidity Allowing sufficient time for the casing liquid to permeate and be absorbed. 5. Cutting Moisture content after cutting Cutting tobacco leaves into strands of the specified width. 6. Drying (Core Stage) Cylinder wall temperature, hot air temperature, internal wind speed, moisture removal volume The most critical stage. High temperatures are used to remove excess moisture, shape the tobacco, and develop aroma. 7. Secondary Winnowing Actual/design moisture content after winnowing Using airflow to remove impurities and further dry the tobacco. 8. Blending & Top Flavoring Stem blending ratio, moisture content after flavoring Final flavor adjustment and mixing.
