AI Technical Summary
Existing tobacco stem pretreatment processes suffer from uneven re-permeability due to a mixture of stem lengths and thicknesses, and lack unified quantitative standards and online detection and closed-loop control, resulting in high stem breakage rate, low whole-shred rate, high energy consumption, and large quality fluctuations.
Based on the precise grading of tobacco stems using both length and diameter dimensions, a quantitative characterization system for the degree of re-permeability is established. Through differentiated stem washing, storage, and steaming processes, combined with parameter compensation using mathematical models, closed-loop control is achieved.
It improved the uniformity of the reflow of the stem fibers, reduced the breakage rate, increased the whole fiber rate, stabilized the moisture content, and achieved precise controllability of the process.
