Test of Cigarette Charging Uniformity Based on Near-Infrared Spectrum

Combined with near-infrared spectroscopy technology applied in tobacco analysis，based on near-infrared spectral analysis of tobacco after charging.It was found that near infrared spectral analysis method could be used in the cigarette charging uniformity.Using scanning spectra and proportion of exerting material liquid，mathematical modeling of near infrared spectral analysis for cigarette charging uniformity was preliminarily explored.Model validation error was within 2%，and it had good practical value.
