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 proc...

Embodiment 1

[0036] (1) The 2009 B2F single-material tobacco was selected as the analysis object, and loosening and re-moisture and shredding pretreatment were carried out before the shredded leaf drying process, so that the moisture content of shredded tobacco was 20-23%. The sample before the collection process was used as a control sample, and the raw material was dried to 12.5-12.6% by heating at an ambient temperature of 28°C. At the same time, the test was carried out according to the gradient combination of processing parameters listed in Table 1, and the samples of processing gradient 1, processing gradient 2, and processing gradient 3 were taken as test samples after the process. Then the collected control samples and test samples were ground into powder, and equilibrated in a constant temperature and humidity chamber (ambient temperature and humidity: 22°C, 60%RH) for 48 hours to be tested.

[0066] (1) Select the high-grade tobacco module as the analysis object, carry out loose re-moisture and shredded pretreatment before processing in the shredded leaf drying process, so that the moisture content of shredded tobacco is 19.5-21.0%. The sample before the collection process was used as a control sample, and the raw material was dried to 12.3-12.5% ​​by heating at an ambient temperature of 25°C. At the same time, the test was carried out according to the gradient combination of processing parameters listed in Table 8, and the samples of processing gradient 1, processing gradient 2, processing gradient 3, and processing gradient 4 were taken as test samples after the process. Then the collected control samples and test samples were cut into filaments, and equilibrated in a constant temperature and humidity chamber (ambient temperature and humidity: 22°C, 60%RH) for 48 hours to be tested.

Abstract

The present invention discloses a method for accurately characterizing cut tobacco drying step material processing intensity. The method comprises: respectively collecting cut tobacco before and after drying; carrying out equilibrium; carrying out spectrum scanning; sequentially carrying out multiplicative scatter correction, second-order partial derivative-Norris derivative filtering, and main component analysis on the spectrum data; respectively establishing class models of the cut tobacco with no drying and the cut tobacco with different drying processing gradients; and calculating to obtain an average of a class model Mahalanobis distance from the cut tobacco with different drying processing gradients to the cut tobacco with no drying so as to determine a processing intensity. With the present invention, qualitative and quantitative expression of the cut tobacco drying intensity is achieved, objective guidance on parameter regulation and control of the drying step for preparing the cut tobacco thread is easily achieved, subjectivity influence on the existing processing intensity judgment is changed, and the intrinsic quality change of the cigarette can be well and objectively judged. In addition, the operation method is simple and easy to perform, and technical effects are 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 drying process of shredded cigarette leaves. 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 enterprises 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 shredded leaf drying process in the process. However, at present, this concept only stay...
