Method for measuring paper process reconstituted tobacco filling value via near infrared diffuse reflection spectroscopy

Abstract

The invention discloses a method for measuring paper process reconstituted tobacco filling value via near infrared diffuse reflection spectroscopy. The method comprises the following steps: (1) collecting samples; (2) collecting an original spectrum; (3) selecting a correction sample set and a validation sample set; (4) determining a sample reference value; (5) pre-processing the spectrum; (6) establishing a PLS model; (7) verifying the model; and (8) measuring the filling value. The method disclosed by the invention is simple, feasible and fast, the near infrared spectrum non-destructive testing technology can be used for not only improving the analysis efficiency and saving the cost, but also has obvious practicability of accurately measuring the reconstituted tobacco filling value, improving the detection efficiency and objectively reflecting the product quality. The method disclosed by the invention has the advantages of fast detection speed, no pollution, environmental protection, high accuracy and good reproducibility, and is suitable for onsite analysis and fast detection of the reconstituted tobacco filling value and online monitoring of product quality fluctuation.

Description

technical field [0001] The invention relates to a method for measuring the filling value of papermaking method reconstituted tobacco leaves by near-infrared diffuse reflectance spectroscopy, and belongs to the field of papermaking method reconstituting tobacco leaves. Background technique [0002] Reconstituted tobacco leaves use discarded tobacco stems, tobacco powder and some low-grade tobacco leaves as the main raw materials, which are processed by different processing methods, and then recombined and processed to make products with shapes similar to or even better than natural tobacco leaves, and used in cigarettes Production. On the one hand, the manufacture of reconstituted tobacco leaves can maximize the utilization of tobacco raw materials and effectively reduce the cost of cigarettes; on the other hand, it is also an effective method to reduce harmful components such as tar and improve the intrinsic quality of cigarettes. and economic benefits. [0003] The fillin...

AI Technical Summary

Problems solved by technology

After the near-infrared diffuse reflection light enters the sample, it undergoes countless reflections, refraction, diffraction, and absorption, and then returns to the incident surface. This kind of analytical light loads the structure and composition information of the sample, and is a fast and environmentally friendly method. Detection technology. At present, there have been reports on the application of near-infrared diffuse reflectance spectroscopy to determine the chemical composition, style, and uniformity of tobacco, but there is no report on the method for the determination of the filling value of reconstituted tobacco leaves by papermaking.
