Study on the Determination Method of Atomizing Agent Content in Heat-not-burn Reconstituted Tobacco by Microwave Technology

Abstract

This paper presents an online determination system for atomizer content in heat-not-burn reconstituted tobacco established by a dual-band microwave sensor independently developed. Employing Ridge regression analysis, collinear variables were effectively eliminated, and combined with gas chromatography, a robust determination model for glycerol content in reconstituted tobacco was successfully established. In addition, the repeatability and stability of the developed determination system were rigorously evaluated. The evaluation results indicate that: (1) The model exhibits a high accuracy with a correlation coefficient of 0.982; the average error is merely 0.33%, and the standard deviation is 0.41%. (2)The system demonstrates excellent measurement precision and stability, effectively overcoming the drift problems of measurement errors over time. This system not only meets quality control needs in reconstituted tobacco production and improves product quality, but also significantly enhances detection efficiency. It is of extremely important significance for promoting the improvement of reconstituted tobacco efficiency and realizing accurate control of product quality.
