Description

A kind of modification method of tobacco slurry pulping process beating degree
Technical field
The invention belongs to reconstituted tobacco technology field, and in particular to a kind of tobacco slurry pulping process beating degree is repaiied Correction method.
Background technology
Produce reality and literature survey result show, the detection of papermaking-method reconstituted tobaccos stock quality at present is mainly using making The detection method of paper industry, the comprehensive quality of slurry is characterized with beating degree and the testing result of fiber wet weight.Existing document weight Point reports the factor based on computational science analyzing influence refining pulp quality, stock quality optimal control correlative study work；Starching In terms of expecting Indexs measure research, Lai Yan is bright etc.[13]It has studied with FS-200 fibre analysers to some paper making raw materials, homogeneous raw material Fibre length, the rugosity of different pulping process be measured, and to the analysis of measured value, Luo Bifeng etc.[14]It has studied influence Beating degree determines the factor of accuracy.Literature research result shows heteroproteose cell beyond fiber such as parenchyma cell, vessel cell Rupture also improves the beating degree of slurry to a certain extent, especially in the extra high tobacco raw material pulping process of heteroproteose cell content In, influence of the heteroproteose cell to beating degree more so, causes its representative and reappearance poor, it is impossible to the quality feelings of reflection slurry comprehensively Condition, it is difficult to control the stability of slurry.
Mass dryness fraction Y-factor method Y is the method for simplifying of measure stock quality index, in reconstituted tobacco production during paper-making pulping Result of practical application shows that same batch reconstituted tobacco chip base key physical index less stable, measure beating degree, fiber are wet The method of weight also needs further demonstration, optimization.Big, fiber fines are fluctuated and there is stock quality in reconstituted tobacco production tobacco slurry Loss and the unfixed problem of sampling amount, cause beating degree, the fluctuation of weight in wet base test result larger, and produce with a collection of product only A mass dryness fraction coefficient is determined, i.e., in same batch products produce, beating degree is carried out using same mass dryness fraction coefficient, fiber wet weight is surveyed It is fixed, further increase beating degree, the inaccuracy of fiber wet weight measure.Again correcting mass dryness fraction coefficient needs 3~4h minute, And upper mixing time about 40~50min is produced, therefore to redefine mass dryness fraction coefficient infeasible for each order of classes or grades at school.Analysis reason is So that tobacco slurry has, its is unique, as fines content, dissolving polymer and colloidal substance (DCS) content are high in slurry, It is therefore desirable to establish a kind of modification method of accurate stock quality index, the stock quality of application mass dryness fraction Y-factor method Y detection is referred to Mark is modified, to meet to instruct reconstituted tobacco pulping process parameter optimization, improve an urgent demand of reconstituted tobacco quality.
