Embodiment 1

[0025] A method for establishing a composition model for evaluating reconstituted tobacco slurry system, the steps are:

[0026] (1) Slurry fiber quality analysis: take different formulations of slurry on the production line and use a fiber quality analyzer to analyze the fiber quality. The measurement method is: take an appropriate amount of slurry and fully dissolve it with a disperser, and take a certain amount of dispersed solution to be tested Pour into the FQA special measuring plastic cup, set the measuring fiber to 4000, the measuring range is 0.07-10mm, measure the fiber length and length interval distribution data of each slurry according to the FQA operating procedures, measure 5 sets of data sets for each sample and take average value;

[0027] (2) Establishment of slurry composition model: by analyzing the average length of pulp fibers (average fiber length 0.20-0.53, 0.53-0.85, 0.85-1.18, 1.18-1.50, 1.50-mm), the addition ratio of additional fibers and the length...

[0036] Table 1. Slurry Fiber Quality

[0037]

[0038] (1) Regression analysis is carried out to the pulp fiber quality (outside fiber consumption, fiber length, fiber length distribution interval) in Table 1: outside fiber consumption (Y 1 ) and fiber length distribution interval: 0.20-0.53(X 1 ), 0.53-0.85 (X 2 ), 0.85-1.18 (X 3 ), 1.18-1.50 (X 4 ), 1.50-(X 5 ) is in accordance with:

[0039] Y 1 =9.5-0.160*X 1 +0.254*X 2 +0.147*X 3 +0.152*X 4 +0.023*X 5 , R 2 =99.6%, the degree of correlation between the above indicators is relatively high.

[0040] variance analysis:

[0041] source degrees of freedom SS MS F P significant return 5 72.628 14.526 213.49 0.000 ** residual error 4 0.272 0.068 total 9 72.900

[0042] F 0.05 (5,4)=6.26,F 0.01 (5,4)=15.52, because F=213.49 >F 0.01 (5,4)=15.52, so the amount of outer fiber (Y 1 ) and fiber length distribution interval: 0.20-0.53(X 1 ), 0.53-0.85 ...

Abstract

The invention aims to provide a method for establishing a model for evaluating the composition of a reconstituted tobacco pulp system. The method comprises the steps of pulp fiber quality analysis, pulp composition model establishment, film base fiber quality analysis, film base pulp composition model establishment and model verification and correction. In the technical scheme of the invention, the slurry composition model is constructed by sampling production line slurry and sheet bases and analyzing the proportion of additional fibers, the length of the fibers and the proportion of each length interval, and the application model is repeatedly verified; compared with the conventional method for evaluating the fiber quality and composition of the pulp by measuring the beating degree and fiber wet reuse through an umbrella-shaped frame, the method has the advantages that multiple parameters and multiple variables can reflect the real condition of the pulp more accurately, measurement can be completed in a short time, and the pulp composition or sheet-based pulp composition can be calculated mutually according to a model; the pulping quality and the regulation and control level of the pulp are effectively improved, and a powerful guarantee is provided for stability and high efficiency of production.

Description

technical field [0001] The invention relates to a method for establishing a composition model for evaluating reconstituted tobacco slurry system and its application, and belongs to the technical field of reconstituted tobacco leaves. Background technique [0002] Paper-making reconstituted tobacco leaves are based on tobacco waste such as tobacco stems, fragments (mainly recured tobacco leaf fragments, referred to as fragments), tobacco dust, stem sticks, ash sticks, and low-grade tobacco leaves, and are made by mechanical pulping technology. The reconstituted tobacco leaves with similar tobacco leaf properties are blended into cigarettes, which not only improves the utilization rate of tobacco raw materials, but also endows cigarettes with more style characteristics. However, factors such as wide sources of raw materials such as tobacco stems, shredded leaves, and minced powder, unstable quality, and the need to add additives, fillers, and reuse of white water during the pr...
