Description
Technical field
The present invention relates to a kind of dry type paper-making method recreated tobacco production technology, be specially and outer fibre or baccy fiber are manufactured paper with pulp into sandwich layer substrate by dry method air forming device, again substrate double-face spray painting tobacco powder and glue class mixture post-drying shaping, belong to cigarette industry reconstituted tobacco technical field.
Background technology
The reconstituted tobacco of cigarette industry is by materials such as the offal produced in Cigarette processing process, broken stalk, fragments, through technical finesse and reconfigure and be processed into sheet or thread reconstituted tobacco product (being also reconstituted tobacoo), reconstituted tobacco has concurrently saves raw tobacco material and can the advantage such as flexible modulation cigarette physicochemical property.Known reconstituted tobacco production method mainly contains roll-in method, thick slurry processes, wet paper manufacturing method and dry type paper process etc., and current take wet paper manufacturing method as main flow, and dry type paper process is in developing stage.The feature of wet paper manufacturing method reconstituted tobacco production technology is first manufactured paper with pulp containing tobacco material and additional ingredients substrate, reduction coating fluid is coated with and drying and moulding again at substrate positive and negative, known coating method has roll-type transfer coated, spraying coating, the coating of V-type tunnel and folder net dip-coating coating etc., and described coating fluid is the medicinal extract of extract modulation or tobacco powder and adhesive mixture.
Improve the selected objective target that spreading rate is reconstituted tobacco industry, the reconstituted tobacoo of manufacturing paper with pulp by YC/T16.3-2003 standard, spreading rate >=40%; On the other hand, improving reconstituted tobacco Filling power, is the effective way of cigarette industry reducing tar and reducing harm.The parameters such as spreading rate and substrate surface are long-pending, mass dryness fraction and Filling power are closely related, and the substrate that wet paper manufacturing method is manufactured paper with pulp, because of reasons such as Filling power are low, poor air permeability, surface roughness are inadequate, is difficult to reach spreading rate>=46%, Filling power>=6.0cm
3/ g index.
In domestic and international published patent or document, method about dry type paper-making method recreated tobacco has multiple, one of them is Chinese invention patent " a kind of dry type paper-making method recreated tobacco and production method thereof " (application number: after being mixed with outer fiber starch by tobacco powder 200810030146.5), be settled down to shaped substrate on forming net by wind stream of supplying gas, more evenly spray trace adhesive, even spread concentrated extract on the substrate, 00808488.2) and " the dry autofrettage of filamentary tobacco and obtained product " (application number: 85105001) of applying in China of Kimberley-Clark Corporation of the U.S. another kind is patent of invention " reconstituted tobacoo and manufacture method and manufacturing system " thereof (application number: that Japan tobacco Inc applies in China, adopt sandwich-type moulding process, first plus fiber is settled down to shaping bottom substrate on forming net (making again load hold layer) by wind stream of supplying gas, uniform spreading last layer tobacco powder and glue mixture interlayer on bottom substrate again, afterwards on interlayer air flow settlement one deck plus fiber become surface layer and compress be dried into reconstituted tobacco, utility model patent " paper-making method reproduced tobacco leaf tobacco powder spraying type coating machine " (application number: 200720157214.5) is that the substrate produced for wet paper manufacturing method carries out spraying coating content, comprise about two deflector rolls be arranged in parallel, the positive and negative both sides of two deflector roll internal common tangent planes are respectively provided with the nozzle of one group of adjustable spray angle, by described nozzle by tobacco powder and amylan mixture double-face spray painting on substrate, due to the relatively fine and close and poor air permeability of substrate, therefore described tobacco powder and amylan mixture can only adhere to over the substrate surface, can not deeply penetrate in substrate internal layer section.
A kind of by baccy fiber raw material or fluff pulp fibers raw material or (baccy fiber+fluff pulp fibers) raw material by dry method of paper-making machine, utilize air flow settlement method, the higher (>=6.0cm of Filling power of manufacturing paper with pulp out
3/ g) substrate, then on substrate coating reduction medicinal extract or tobacco powder class effective ingredient, drying and subsequent handling, make reconstituted tobacoo finished product, reaches spreading rate>=46%, Filling power>=6.0cm
3the process of/g index, does not see in patent database or the open Reporting of document.
