Embodiment

[0028] Tobacco sheets from 7 different manufacturers were collected, and the samples were flexibly decomposed to obtain a fiber suspension. An appropriate amount of fiber suspension was used for fiber analysis with a fiber quality analyzer, and the tensile index was measured according to GB / T12914-2008. The results are shown in Table 1.

[0029] Table 1 Fiber morphology index and longitudinal tensile index of seven different tobacco sheets

[0030]

[0031] The linear equations obtained from Table 1 are as follows:

[0032]

[0033] Randomly select 6 equations to form a one-variable linear equation system, and solve their independent variable coefficients. The results are shown in Table 2. shown.

[0037] The prediction equation is obtained as follows:

[0038]

[0039] Substitute the parameters of the seventh sample into the obtained model to calculate the relative err...

Abstract

The invention provides a tobacco sheet physical property prediction mode establishment method. The method comprises the following steps of performing flexible defibering on different tobacco sheet samples, determining the fiber length, width and roughness, the fiber roll curvature, the fiber twist index and the fine fiber content, establishing a linear relation with the tobacco sheet physical property, and carrying out rapid prediction on the tobacco sheet physical property based on the relation. According to the method disclosed by the invention, the rapid prediction of the physical properties of the tobacco sheet can be directly carried out through the morphology analysis of the slurry fiber under a factory condition, the problem that the existing sample detection data lags behind the production operation is solved, the detection time of the key physical property of the sample is saved, and the online regulation and control of the product quality are realized.

Description

technical field [0001] The invention belongs to the technical field of tobacco sheet production and detection, and in particular relates to a method for establishing a physical property prediction model of tobacco sheet. Background technique [0002] Tobacco flakes are made from low-grade and waste tobacco raw materials that cannot be directly used in cigarette products, such as tobacco stems and tobacco powder, and are also called reconstituted tobacco leaves. Usually there are process methods such as roll pressing method, thick pulp method and paper making method. Papermaking reconstituted tobacco has been accepted and adopted by the world's tobacco production industry as the mainstream trend of reconstituted tobacco due to its high added value, high filling rate and special functions in reducing tar and harm. [0003] After decades of continuous development, the production process of papermaking reconstituted tobacco has been perfected day by day, but its quality control...
