Abstract
The present invention discloses a pulping method of tobacco stems for producing tobacco flakes by using a papermaking method. The tobacco stems are soaked in hot water at 40-70 DEG C for 1 to 2.5 hours for extraction, the solid-liquid separation of the tobacco steams is carried out, and solid tobacco stems and tobacco stem extract are obtained; the fiber dissolution of the solid tobacco stems is carried out by using conventional equipment which is known by chemical engineering profession, and the beating degree of once fiber dissolution is 10 to 25 DEG SR; the beating degree of secondary fiber dissolution is 13 to 26 DEG SR; the beating degree of tobacco stem fiber entering finished pulp is 14 to 30 DEG SR. The present invention has the essence that the present invention changes a pulping technology of the tobacco stems in the production of the tobacco flakes by using the papermaking method and indexes of the pulping technology according to the property of the tobacco flakes and the main functions of the tobacco flakes in a tobacco formula, the filling property of tobacco flakes made by using a papermaking method is enhanced, and the burst size of tar of cigarettes is utmost reduced. Simultaneously, the requirements of industrial production are satisfied, and the utilization rate of the tobacco flakes made by using the papermaking method in the tobacco formula.
Description
Technical field
The present invention relates to a kind of pulping process of offal, especially relates to a kind of pulping process that adds the offal in the cigarette ash producing tobacco flake in method similar to papermaking.
Background technology
Reconstituted tobacoo is to be raw material with the tobacco dead meal in the cigarette process such as offal, offal, tobacco leaf fragment and part discarded tobacco leaf etc., through reconfiguring the reconstituted tobacco that processes.Can utilize raw tobacco material to greatest extent on the one hand, save the cigarette cost; Reconstituted tobacoo lowers cigarette harm aspect and has brought into play important effect in the burst size that reduces coke tar in cigarette on the other hand.The production method of existing reconstituted tobacoo mainly contains thick slurry method and paper process.Thick slurry method reconstituted tobacoo is the thick slurry that is mixed and made into homogeneous with offal and certain glue mutually, is being uniformly coated on drying forming on the steel band.The reconstituted tobacoo of producing by thick slurry method is because offal is many, and fiber is few, and so physical property is relatively poor, filling power is little, in cigarette composition, contributes little to the attenuating of the burst size of coke tar in cigarette.In addition, owing to must need the sticking of glue and ability moulding, burn and suck in the process at cigarette product, the thermal decomposition product of glue inevitably enters flue gas, thereby influences the fragrance and the mouthfeel characteristic of cigarette product.The reconstituted tobacoo that adopts paper process to produce is a kind of method that thick slurry method is produced tobacco sheet that is different from fully, and it is in physical property, and filling capacity is better than thick slurry method thin slice, tar and the harm that can more effectively lower cigarette smoke far away.Along with the concern of masses to smoking and health, country is to the reinforcement day by day of cigarette product tar control, and tobacco sheets by paper making method occupies more and more important position in cigarette composition.Usually the tobacco sheets by paper making method its preparation method has following steps: earlier with tobacco (offal, tobacco leaf fragment) extracts with hot-water soak, through solid-liquid separation step the tobacco hydrotrope is separated with insoluble matters such as baccy fibers, the gained fiber is molded into thin slice sheet base on the paper machine, the gained hydrotrope is concentrated through distilling, and obtains the tobacco concentrate.Gained concentrate dip-coating or spray on the thin slice sheet base, last drying becomes reconstituted tobacoo.In the process of the producing tobacco flake in method similar to papermaking of above-mentioned common employing, traditional technology is all used for reference the method for papermaking, and in the pulping process, it all continues to use the index of papermaking to the technic index of beating degree, and the last beating degree of separating behind the fibre of offal reaches 40-50 ° of SR.Be planarization and compactness in order to guarantee paper.But in the process of reconstituted tobacoo, be gas porosity and out-of-flatness to the requirement of reconstituted tobacoo, gas porosity is relevant with the filling capacity of out-of-flatness and reconstituted tobacoo, and the gas porosity of thin slice and out-of-flatness are high more, and its filling capacity is just good more.So originally traditional paper process is separated fine beating degree can not satisfy the production reconstituted tobacoo.
Summary of the invention
Technical problem to be solved by this invention provides a kind of pulping process that can improve the offal of reconstituted tobacoo physics filling capacity when adopting producing tobacco flake in method similar to papermaking.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: offal is soaked extraction in 1-2.5 hour in 40-70 ℃ hot water, through Separation of Solid and Liquid, obtain solid offal and offal extract; With the conventional equipment that this specialty is known the solid offal is separated fibre, once separating fine beating degree is 10-25 ° of SR; It is 13-26 ° of SR that secondary is separated fine beating degree; The beating degree that enters finished product slurry tobacco stalk fibre at last is 14-30 ° of SR.
Described offal is an offal of beating the length 1-3mm of leaf operation generation in the cigarette process.
As a kind of improvement of the present invention, once separating fine beating degree is 12-20 ° of SR; It is 15-22 ° of SR that secondary is separated fine beating degree; The beating degree that enters finished product slurry tobacco stalk fibre at last is 18-25 ° of SR.
The finished product tobacco stalk fibre that adopts technique scheme to obtain, to add the plus fiber of separating behind the fibre compound with cigarette ash again with the tobacco leaf fragment fiber, makes the sheets of fibres substrate through paper machine making; The offal extract directly give up need not, the tobacco leaf fragment extract concentrates through distillation, spraying or dip-coating are to the sheets of fibres substrate of moulding again, drying is beaten sheet, moulding.
Essence of the present invention is from the characteristic according to reconstituted tobacoo, the major function tobacco blend from reconstituted tobacoo, change the technology and the index of offal slurrying in the tobacco sheets by paper making method production, improve the filling capacity of paper process tobacco sheet, reduced the releasing content of coke tar of cigarette to a greater extent.Simultaneously, satisfy industrial requirement.Improve the utilization rate of paper process thin slice in tobacco blend.
