Abstract
The invention discloses a kind of tobacco pulp pulping process controlled flexibly, carry out middle concentrated jordaning and the low dense defibrination of two-stage according to tobacco material beating degree or skip middle concentrated jordaning, directly carrying out low dense defibrination.The defibrination mode that the present invention adopts middle concentrated jordaning to combine with low dense defibrination, the advantage of dense in giving full play to, low dense defibrination, or directly carrying out low dense defibrination, the tobacco material for different conditions selects optimal defibrination mode, obtains the tobacco slurry with steady concentration and beating degree.
Description
Technical field
The invention belongs to reconstituted tobacco production field, specifically a kind of tobacco pulp pulping process controlled flexibly.
Background technology
Defibrination is the basis of papermaking-method reconstituted tobaccos production technology.Current domestic papermaking-method reconstituted tobaccos defibrination mode mainly imitates the two-part defibrination of pulping and paper-making industry, and namely fixing high consistency refining adds the processing mode of low dense defibrination.High consistency refining process xylon can reach good wire-dividing broom purification effect, avoids excessive conquassation and the cut-out of fiber, and low dense defibrination can play expansion and cut off effect; But morphosis and the strength difference of tobacco material and xylon are larger, tobacco material fiber content is low, intensity difference, and containing more colloid and heteroproteose cell, as xylon, wire-dividing broom purification can not be produced under high consistency refining process, tobacco material can be made on the contrary excessively broken.In addition, high consistency refining also have that energy consumption is large, input concentration is unstable, the shortcoming such as wayward, low precision.Fixing high consistency refining mode can make tobacco material excessively broken, causes that slurry evenness is poor, concentration and beating degree instability, sheet bulk are low, pliability and the shortcoming such as absorbability is poor, spreading rate is low, thus makes tobacco aesthetic quality not good enough.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, a kind of tobacco pulp pulping process controlled is flexibly provided, the defibrination mode that this technique adopts middle concentrated jordaning to combine with low dense defibrination, in can giving full play to, the advantage of low dense defibrination, make the tobacco material of different conditions by the difference of concentration, beating degree, select optimal defibrination mode, finally carry out follow-up manufacturing paper with pulp with stable concentration and beating degree, the sheet bulk produced is good, pliability promotes, absorbent is good, spreading rate improves, and has both improved physical quality and has also improved organoleptic quality.
For solving the problems of the technologies described above, the invention provides a kind of tobacco pulp pulping process controlled flexibly, comprising the following steps:
(1) middle concentrated jordaning: tobacco material is dense in passing into through tentatively discongesting, after shove kowtows in forebay, its mass percent concentration is 5% ~ 10%, on-line checkingi beating degree, if beating degree is being less than 14 ° of SR, then be delivered to middle-density refiner, after middle concentrated jordaning, again detect beating degree, until beating degree within the scope of 14 ~ 18 ° of SR after be delivered in densely kowtow after-bay; If beating degree within the scope of 14 ~ 18 ° of SR, then skips middle concentrated jordaning, densely in being directly delivered to kowtow after-bay;
(2) the low dense defibrination of one-level: in dense slurry of kowtowing after-bay to be adjusted to mass percent concentration by plain boiled water be 3% ~ 5%, the low dense defibrination of one-level is carried out through the low dense fiberizer of the first order, through on-line checkingi beating degree, if beating degree is within the scope of 21 ~ 25 ° of SR, is then directly delivered to and lowly densely kowtows rear transition pond; If beating degree is lower than within the scope of 21 ° of SR, is then again delivered to the low dense fiberizer of the first order and carries out the low dense defibrination of one-level, until beating degree is within the scope of 21 ~ 25 ° of SR, is delivered to and lowly densely kowtows rear transition pond;
(3) the low dense defibrination of secondary: low dense fiberizer carries out the low dense defibrination of secondary to low dense slurry transferring of kowtowing rear transition pond to the second level, through on-line checkingi beating degree, if beating degree is within the scope of 28 ~ 32 ° of SR, is then directly delivered to and lowly densely kowtows after-bay; If beating degree is lower than 28 ° of SR, is then again delivered to the low dense fiberizer in the second level and carries out the low dense defibrination of secondary, until beating degree is within the scope of 28 ~ 32 ° of SR, is delivered to and lowly densely kowtows after-bay.
The present invention is under the stable lower beating degree of tobacco material, first by middle concentrated jordaning, tobacco material is discongested, slurrying, ensure that evenly discongesting of slurry under dense state, thus make the stability of follow-up low dense defibrination input concentration and beating degree, and in avoid under dense state producing the macromolecular substances such as too much tiny broken thing and pectin.Or according to the beating degree detected, under the higher beating degree that slurry is stable, after thickening, skip middle concentrated jordaning, directly carry out low dense defibrination, handling flexibly is carried out to slurry, avoid excessive defibrination, thus improve slurry evenness and sheet bulk.
The present invention solves concentration in tobacco material defibrination process, the uncontrollable problem of beating degree by defibrination mode controlled flexibly, and compared with existing fixing high consistency refining mode, making beating power consumption about 25% can be saved, the bulk of finally manufacturing paper with pulp into paper is also greatly increased, and spreading rate also synchronously improves 3% ~ 5%.
