Research on impurity detection method in tobacco shred based on spectral analysis

During the production process of tobacco shreds, various impurities are easily mixed in. Traditional manual and visual detection methods are inefficient with low detection rates. This paper constructs a near-infrared spectroscopy system for foreign matter detection in tobacco shreds, conducts experimental verification and data analysis on different types of impurities in tobacco shreds, demonstrates the feasibility of applying near-infrared spectral analysis in the field of tobacco shred impurity removal, and proposes a new method for detecting impurities in tobacco shreds.
