Tobacco shred structure determining method and device suitable for thin cigarettes

Abstract

The invention discloses a tobacco shred structure determining method and device suitable for thin cigarettes. The tobacco shred structure determining method comprises the following steps: tobacco shreds of different lengths are subjected to mixing combination through a mixing uniform design method, and a plurality of tobacco shred structures are obtained; the physical index and the smoke index ofeach cigarette made of the corresponding tobacco shred structure are detected, and variable coefficients of all the indexes are calculated; all tobacco shred component proportions in the tobacco shredstructures are subjected to quadratic polynomial stepwise regression analysis, regression function models of all tobacco shred components and the variable coefficients of all the indexes are established, the regression function models are optimized, and tobacco shred length intervals and the variable coefficients corresponding to all the optimal indexes are obtained; the variable coefficients ofall the indexes are compared through combination of the Delphi method and an adjacent index comparison method to determine weights of all the indexes; and the weights of all the indexes and the variable coefficients of all the indexes are subjected to weighted average calculation, all the tobacco shred component proportions corresponding to the minimum variable coefficients of all the indexes areobtained, and the optimal tobacco shred structure is determined.

Description

technical field [0001] The disclosure relates to the field of cigarette processing technology, in particular to a method and device for determining the structure of shredded tobacco suitable for slim cigarettes. Background technique [0002] As a fast-growing new category of Chinese-style cigarettes, slim cigarettes have natural advantages in the fields of harm reduction, coke reduction, energy conservation and environmental protection, and cost reduction and efficiency enhancement. There are few reports on the impact of the cut tobacco structure of slim cigarettes on the physical indicators of cigarettes. Most studies have been conducted on conventional cigarettes. Among them, the structural characteristics and processing technology of shredded tobacco have received greater attention in the process development in recent years. [0003] In recent years, with the rapid development and improvement of tobacco technology, basic research is relatively weak. Threshing and redryin...

AI Technical Summary

Problems solved by technology

[0005] During the research and development process, the inventors found that in the characterization method of shredded tobacco structure of conventional cigarettes and the analysis method of the influence of shredded tobacco structure on cigarette quality, since the shredded tobacco structure is a resultant index, and the influence of various mechanical forces in the shredded process, it will Random crushing occurs, the structure of cut tobacco is less controlled, the stability between batches is low, and it is difficult to fine-tune the structure of cut tobacco, which limits the optimization, screening and determination of suitable cut tobacco structure to a certain extent
