Method for accurately representing material machining strength in cigarette loosening and moisture-regaining process

Abstract

The invention discloses a method for accurately representing material machining strength in a cigarette loosening and moisture-regaining process. The method comprises the following steps of: respectively acquiring tobacco before and after loosening and moisture-regaining, balancing and subsequently carrying out spectrum scanning, carrying out multiplicative scatter correction as well as two-order partial derivative and Norris derivative filtering on the spectrum data, carrying out main component analysis, respectively establishing class models of non-loosened and moisture-regained tobacco and tobacco with different loosening and moisture-regaining machining gradients, and finally calculating so as to obtain the class average values of the mahalanobis distance between the class models of the tobacco with the loosening and moisture-regaining machining gradients and the non-loosened and moisture-regained tobacco, and thus judging the machining strength. The qualitative and quantitative expression of the tobacco loosening and moisture-regaining strength is realized, the parameter adjustment and the control to the tobacco shred making line loosening and moisture-regaining process are facilitated, the degree that the conventional machining strength judgment is easy to be affected subjectively is reduced, and the internal quality change of the cigarette can be subjectively judged; and the operation method is simple and easy to carry out, and the technical effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a method for accurately characterizing the internal quality change of material processing intensity during the loosening and rehydration process of cigarette shreds. Background technique [0002] The 2003 edition of "Cigarette Process Specifications" put forward a new control concept from "result control to process control" for the cigarette production process, and the development of Chinese-style cigarette characteristic technology also puts forward new requirements for the optimal control of process parameters in the key process of cigarette silk making . Domestic tobacco companies and scientific research institutes have carried out a series of analysis and research on the process technology around this requirement, and put forward the concept of processing strength in the loosening and rehydration process in the process. However, at present, this conc...

Problems solved by technology

However, at present, this concept only stays in the fuzzy description through the collocation of processing parameters combined with the change of sensory quality, and has not yet been able to express the expression of the intrinsic quality change of processing intensity in a specific and objective qualitative and quantitative way, which has caused tobacco companies to make serious changes in the actual production process. In the process, it is impossible to scientifically and objectively guide the parameter adjustment and control of the loosening and moisture regaining process of the silk thread, which is not conducive to the in-depth research of the characteristic process technology, so that the enhancement of the contribution rate of the processing process to the product quality, the improvement of product quality, and the role of highlighting the individualization of the product are subject to a certain degree. limit
