A Tobacco Leaf Grouping Method Based on Dynamic Changes of Raw Material Quality

Abstract

The invention discloses a tobacco grouping method based on raw materials quality dynamic changes. The method comprises the steps that loosing and conditioning and thin plate drying are carried out on cigarette blending formulation raw materials to be grouped according to the same technology, and tracking and sampling are carried out on the raw materials before loosing and conditioning at the outlet of the thin plate drying procedure; the crush resistance and precursor-aroma compound content of the non-processed raw materials and the crush resistance and precursor-aroma compound content of the processed raw materials are detected; the change rate of the crush resistance and precursor-aroma compound content of the cigarette blending raw materials is calculated; clustering is carried out based on the changing rate of the crush resistance and precursor-aroma compound content of the cigarette blending raw materials, and the cigarette blending formulation is divided into two to three modules. According to the tobacco grouping method based on the raw materials quality dynamic changes, the tobacco raw materials are grouped according to the raw material quality change degree, the tobacco quality dynamic changes and raw material processing characteristics in the tobacco primary process are sufficiently considered, the grouping result is more scientific, more objective and more exquisite, sensory evaluation is not needed, the number of detection indexes is small, the detection method is easy to implement, the detection result is object and accurate, man-made subjective factor influences existing on sensory evaluation are avoided, and the grouping result is more reliable.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a tobacco leaf grouping method based on the dynamic change of raw material quality during the cigarette grouping process. Background technique [0002] In the traditional silk-making process, the tobacco leaf processing technology is relatively extensive, and the tolerance of cigarette process design is weak. The characteristics and use value of tobacco leaves of different quality and processing performance cannot be fully reflected, and the characteristics of each cigarette brand cannot be highlighted. Group processing can carry out targeted processing methods for tobacco leaf raw materials of different grades, styles and processing characteristics, and enhance the role and use value of each cigarette leaf group in cigarette formula. At the same time, group processing is also the basis for the development of "Chinese-style cigarette" characteristic techn...

Problems solved by technology

[0004] In the above technologies, relying on the sensory characteristics of the cigarette formula leaf group, or relying on the chemical components and aroma components of the leaf group, there are still some problems as follows: ① During the sensory evaluation process, there are differences in the sensory evaluation skills of smokers, personal Subjective factors such as preferences will seriously affect the accuracy and reliability of the grouping results; ②The above methods do not involve the mechanical processing performance of different formula leaf groups. For raw materials with poor mechanical processing performance, the tobacco leaves produced during the processing Fragmentation will affect the stability and unit consumption of cigarette formula; ③The classification is based solely on the coordination of chemical components of raw materials or the content of aroma components, ignoring the quality changes of tobacco leaf raw materials during processing. The scientific and rationality of the grouping results is worthwhile. to consider
