Problems solved by technology

[0003] Chinese patent CN1830335A discloses that a number of different grades of tobacco leaves with the same or similar style characteristics are combined according to a certain ratio, so that they become a formula module with certain functions or uses in the cigarette formula for threshing and redrying. The patent is mainly Aiming at the problem of group processing in the process of threshing and re-roasting, there is also the question of whether the combination standard is scientific and reasonable

Embodiment Construction

[0017] In this embodiment, the classification and grouping of flue-cured tobacco leaves of the same year and the same grade in 29 representative points in the tobacco leaf raw material planting area is taken as an example for illustration.

[0018] Step 1): PCA multi-index compression

[0019] Generally speaking, there are many indicators to describe the ecological characteristics of tobacco raw material planting areas, and both geographical and meteorological aspects should be considered. To this end, 10 representative indicators were selected, including altitude, sunshine, accumulated temperature ≥10°C, average temperature in May, July, and September, annual precipitation, precipitation from May to September, longitude, and latitude, and recorded them respectively. X1, X2, ..., X10, see Table 1 for specific data.

Abstract

The invention discloses a tobacco raw material classifying and grouping method. The method comprises the steps as follows: collecting ecological information of a tobacco planting land, extracting the major component of the ecological information, analyzing the extracted major component with cluster analysis to obtain the classification result, and verifying the classification result; and after the tobacco raw materials are classified, collecting chemical constituent indexes of the tobacco raw materials, extracting the major component of the chemical constituent indexes, analyzing the major component with cluster analysis to obtain the grouping result, and verifying the grouping result. The method classifies the tobacco raw materials according to the ecological information of growth in terms of the characteristics of the tobacco raw materials as agricultural products, takes into consideration that the tobacco raw materials serve as the processing raw materials of industrialized products, and groups the tobacco raw materials in the same category according to the chemical constituents. The classifying and grouping method can provide scientific and reasonable guide and support for cigarette formulation design, threshing and redrying, and establishment of group processing module, facilitates the quality improvement of cigarette products, and draws on tobacco raw materials more scientifically and reasonably.

Description

technical field [0001] The invention belongs to the field of tobacco utilization, and in particular relates to a method for classifying tobacco leaves and a method for grouping tobacco leaves. Background technique [0002] Tobacco leaf raw material is the basic material of cigarettes and the first workshop of cigarette production. Due to the differences in tobacco leaf growth factors such as altitude, temperature, and light in different regions, the different growth conditions such as soil, water and fertilizer, and the differences in tobacco leaf varieties and growth parts , The quality of tobacco leaf raw materials of the same grade varies greatly. How to use them reasonably and scientifically classify and group tobacco leaf raw materials has always been one of the key and difficult issues in the research of tobacco leaves as industrial processing raw materials. [0003] Chinese patent CN1830335A discloses that a number of different grades of tobacco leaves with the same o...
