Abstract

The invention discloses a re-drying quality stability evaluation method based on tobacco leaf characteristic spectrum consistency measurement, and belongs to the technical field of tobacco leaf quality control research. The method includes the steps: automatically acquiring spectroscopic data of re-drying flue-cured tobacco laminas of each box by the aid of an online near-infrared device; extracting characteristic spectrums representing comprehensive quality characteristics of tobacco leaves by the aid of correlation analysis of tobacco leaf quality and near-infrared spectrums; building a spectrum consistency measurement model according to re-drying production realities to evaluate the re-drying quality stability of the tobacco leaves. According to the method, the spectroscopic data are automatically acquired, real-time evaluation of the model is achieved, a whole process is automatic and on-line, sampling and sample manufacturing processes are omitted, and the built evaluation model is more comprehensive, objective and scientific and has good guidance and practicability for quality control in the re-drying process of the tobacco leaves.

Description

technical field [0001] The invention relates to a method for evaluating the stability of redrying quality, in particular to a method for evaluating the stability of redrying quality based on the consistency measurement of characteristic spectra of tobacco leaves. The invention belongs to the field of quality control of tobacco leaves. Background technique [0002] Tobacco leaf is the most important material basis for determining the quality of cigarette products, and its quality stability is the basis for the stability of cigarette product quality and brand expansion. As an agricultural product, tobacco leaf is affected by natural conditions such as light, rain, and soil, and its quality fluctuates greatly, which is difficult to meet the needs of industrialized cigarette production. Re-baking processing refers to the process of re-baking the raw tobacco that has been prepared initially, and transforming tobacco leaves from agricultural products into industrial raw materials ...
