A Classification Method for Processing Attributes of Threshing and Red-cured Tobacco Leaves

Abstract

The invention relates to the technical field of tobacco leaf processing, in particular to a method for classifying processing attributes of threshed and recured tobacco leaves. The method includes the following steps: selecting the physical quality index of tobacco leaves as a feature, measuring the characteristic data of the tobacco leaf samples to be classified; determining the number K of clusters; selecting K tobacco leaf samples as initial cluster centers; calculating the relationship between other tobacco leaf samples and the cluster centers Euclidean distance, according to the criterion of the closest distance, classify all tobacco leaf samples into the category corresponding to the nearest cluster center; calculate the mean value of each feature of all tobacco leaf samples in the same category, and use it as the new clustering center of the category Cluster center: Repeat the above two steps until the set number of iterations is reached or until the mean is consistent with the cluster center. Through the application, not only the efficiency of threshing and redrying is improved, but also the matching degree of processing intensity and tobacco leaf processing properties is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf processing, in particular to a method for classifying processing attributes of threshed and recured tobacco leaves. Background technique [0002] The quality of threshing and redrying is not only closely related to the production process, but also the physical characteristics, chemical composition and quality style of the tobacco itself play a decisive role. The physical characteristics of tobacco leaves reflect the internal quality and technological performance of tobacco leaves to varying degrees. The change of chemical composition of tobacco leaves in the process of threshing and redrying is also an important factor reflecting its processing attributes. The raw materials of tobacco leaves in the process of threshing and redrying The change of quality style is the main factor that determines the quality of tobacco leaf raw materials used. At present, the research on threshing and redrying ...

AI Technical Summary

Problems solved by technology

The invention adopts cutting of tobacco leaves, sorting and processing of leaf bodies and petioles, respectively threshing and redrying, and adopts different processing intensities and individualized processes according to the differences in physical and chemical properties of tobacco leaf bodies and petioles, but for different types of tobacco leaves, it is still the same. The leaf body and the petiole are processed together. Tobacco leaves that require low processing intensity may still be threshed and re-roasted together with tobacco leaves that require high processing intensity, resulting in the internal quality loss of tobacco leaves due to excessive processing intensity or insufficient processing intensity.
