Description
Technical field
The present invention relates to a tobacco articles and processing technology thereof, particularly manufacture the techniques and methods of the substrate of reconstituted tobacco with dry method of paper-making law technology.
Background technology
Reconstituted tobacco is also known as recombination tobacco leaf, homogeneous tobacco leaf.Primarily of offal fragment, offal or discarded tobacco leaf, additional string, adhesive and other additive form.Reconstituted tobacco is now widely used as cigarette products as tobacco product raw material.Utilize tobacco low order raw material to laminate to have that cost is low, fillibility good, and the features such as tar content to be reduced in flue gas, manufacture and start from the 1950's.Manufacture method mainly contains paper process, thick slurry processes and roll-in method three kinds of methods, because thick slurry processes, roll-in method technique fall behind and many reasons of product quality aspect relatively, there is no and be widely used and be eliminated gradually, substantially widely used now paper process technology and produce reconstituted tobacco substrate.
Paper process; traditional paper process exactly; that tobacco powder offal, offal or abandoned tobacco raw material are first used water extracted tobacco extract; extract rear water-insoluble matter interpolation/or do not add after slurry made by natural fiber and enter paper machine; beginning to take shape gauze, is the substrate (water-soluble extract is applied to substrate in subsequent handling more in the lump with other additives after concentrated) of reconstituted tobacco after drying.The thin slice that this method is produced, physical strength is high, and wet fair by force, bulk density is light, and burning velocity is very fast, generates tar low.Due to complex process, energy consumption is high, and equipment investment is large, is applicable to large-scale production.
Both at home and abroad by research and the use in twenty or thirty year, this technology obtains development fully and improves, and is extensively used in production of cigarettes.But also there is the defect of several aspect: one is adopt traditional paper technology, and produce large amount of sewage in production, belong to serious pollution production technology, sewage disposal and blowdown presssure are very large; Two is that tobacco material smoke and cigarette perfume in process lose obviously, its offal used and tobacco chippings need by lixiviate in water, water-soluble tobacco ingredient wherein has significantly sacrificing in concentration process, and insoluble tobacco material loses also clearly in defibrination process subsequently, the smoke cigarette of the reconstituted tobacoo consequently produced is fragrant not enough, non-tobacco is jealous and assorted gas outstanding, affects sucking quality; Three is that the paper substrate structure that this method is produced hardens, smooth surface, load capacity is not enough, the spreading rate of current traditional tobacco sheets by paper making method (the tobacco material such as the tobacco extract of interpolation accounts for the mass percent of finished product) is generally about 40%, the high sucking quality defect that must cause reconstituted tobacoo of content of the few paper substrate of tobacco material of interpolation; Four is that the structural capacity of the paper substrate of traditional paper process manufacture is provided by the hydrogen bond between fiber, although structural strength is good but wet very poor by force, the tensile resistance of paper substrate is more weak, limit the speed in follow-up coating process, easily disconnected paper and breaks in production, stretch-proof defect and wet strong defect not only affect production capacity but also cause production technology unstable.For wet papermaking method reconstituted tobacco substrate Problems existing, fall under burnt demand reconstituted tobacoo uses the overall background more and more come into one's own, all at the tobacco sheets by paper making method substrate manufacturing technologies that exploration is new for meeting Harm reduction techniques especially at home.
Solve in more above-mentioned problems in searching, patent ZL00808488.2, proposes the method for the manufacture thin slice of similar manufacture non-woven fabrics.First hold layer by the load that string is made into cloth-like, hold on layer in load and add tobacco powder.Because string and tobacco powder do not have caking property, must add pulverous adhesive when adding tobacco powder, after humidification, heating pressurization, makes it into and is integrated simultaneously.Also after interpolation tobacco powder, add a nonwoven layer be made up of string again as cap layer by design, make the flake structure of a kind of two fibre layers sandwich one deck tobacco powder offal like this.After needing humidification in the forming process of this thin slice, heating is pressurizeed, and makes string straticulation structure bonding with tobacco powder offal.There is obvious defect in this design, main manifestations is: structural slab is real, and its density is comparatively large, is about 0.73g/cm
3, Filling power is little, compared with existing wet papermaking method thin slice, does not have clear superiority; Adhesive strength is little, and its glue added is mixed in tobacco powder offal, and the bonding force between tobacco powder offal and plant fiber layer is very weak, shows as tab strength defectiveness; Tobacco powder offal is a pantostrat substantially, and after gummed, toughness is inadequate, easy dry linting in thin slice cutting process, and in actual production, useful value is subject to drastic delimitations; This outer adhesive use amount is large, also have impact on cigarette odor-absorbing to a certain extent.Compare with traditional papermaking-method reconstituted tobaccos, its advantage is also not obvious, and even because of design defect such as its complex process and easy dry lintings, its actual use value is far below traditional papermaking-method reconstituted tobaccos.
Patent 200810030146.5 it is also proposed a kind of technical scheme of dry type manufacturing tobacco flake by paper-making process, is the complex art that a kind of wet papermaking law technology and thick slurry processes technology combine in fact.Specific practice is abandoned tobacco raw material, and namely the water such as offal, offal extracts, and continue to employ after extract is concentrated, then extraction slag and additional wood pulp cellulose defibrination are obtained mixed slurry, this part technique is completely with traditional wet papermaking method technique; Then slurry oven dry is made the dry pulp powder about 80-200 order, wind is adopted to deliver to pair roller place, shaping position, powder thin layer is formed through extruding, the adhesive of trace is sprayed again on the thin layer formed, again concentrated extract is coated on substrate equably, be dried to the mass dryness fraction of setting, become the finished product of reconstituted tobacco.This part technique is with the technique of thick slurry processes.The starch order number that the method is obtained by defibrination is between 80-200 orders, and infer that the shaping mesh of its air lay must be less than 200 orders accordingly, its air permeability certainly will cause shaping difficulty.Because tiny is Powdered, be deposited in after air lay on forming net, gap between powder is less, denser, add that spraying glue and extract can increase the packing of substrate further, though its fluffy degree and bulk density are not mentioned, compare wet papermaking method does not have very large advantage on loading, because do not have good fluffy degree not have good filling capacity.Another because 80-200 object powder, fiber is shorter complete in a small amount of adhesive and extract bonding, and the intensity of this thin slice, especially wet exist serious problems by force.Just because of the significant deficiency that the method exists on molded design, drastic delimitations uses the method to produce qualified reconstituted tobacco.
All still there is substrate and to wet strong defect in the substrate that current traditional paper process technology manufactures the reconstituted tobacco that reconstituted tobacco substrate or similar patent 200810030146.5 and patent ZL00808488.2 are mentioned, follow-up process industrial art performance is poor, filling capacity is not enough, the potentiality of the tobacco material of load are little, and sucking quality defect, limit the use of reconstituted tobacoo in cigarette.
Summary of the invention
For above-mentioned problems of the prior art, inventor attempts adopting Paper DryForming Technology to produce reconstituted tobacco substrate first.But inventor finds: adopting dry method of paper-making method to be used for reconstituted tobacco production process needs to overcome a large amount of electrostatic produced in preparation process; In addition, it is combine by hydrogen is strong that reconstituted tobacco substrate of the present invention no longer prepares reconstituted tobacco as wet papermaking, not too need how many binding agents (most wet papermaking does not add adhesive), and the inventive method attempts adopting Paper DryForming Technology to manufacture substrate, effectively combine for making substrate, design and add adhesive in substrate surface spray, but the selection of tobacco business to adhesive has high requirements, not only there is the requirement adding security, and require that the adhesive added obviously can not affect smoking quality.In addition, how when using a large amount of adhesive to add, also need to meet substrate further and do strong requirement and prior requirement that is strong and tensile resistance of wetting, make substrate not only have good structural strength, and in follow-up process, certain wet strong and tensile resistance can also be had after absorbing the solution being several times as much as substrate sole mass.By force wet and tensile resistance is that a great problem faced prepared by current reconstituted tobacco substrate preferably.Reconstituted tobacco substrate inventor obtained by the present invention is through research and development repeatedly for many years, successfully overcome above-mentioned technical barrier, and successfully adopt that dry method of paper-making method manufacture to obtain having compared with high humidity by force first, stronger tensile resistance, high load capability, high Filling power, excellent machinability reconstituted tobacco substrate.
Technical scheme of the present invention is: adopt comprise offal, string raw material through pulverize separate fine become after short fiber wind send into after forming head case breaks up, the forming net making the uniform laying of breaing up rear material be adsorbed on the dry method of paper-making by the vacuum action of the vacuum suction device under forming net forms fibre thin layer; Add adhesive to fibre thin layer spray, employing be that spraying spray adds and spray the mode combined of back side vacuum draw; Finally by drying the substrate obtaining the reconstituted tobacco with dimensional network structure; Between forming net top and forming head case and/or between forming net and vacuum tank opening, be equipped with antistatic rope, and/or be provided with antistatic net between forming net and vacuum tank opening; Described adhesive comprise shitosan and starch adhesive and/or cellulose derivative and/or and other there is the natural plants polysaccharide (e.g., galactomannans, glucomannans, Arabic gum etc.) etc. of good bonding performance.In described adhesive components, shitosan is required component, other component can select on demand one or more and shitosan wherein with the use of, wherein the addition of shitosan is not less than 2% of described substrate gross mass, and other the total addition level of adhesive components such as starch adhesive and/or cellulose derivative is not less than 0.5% of described substrate gross mass; The total addition level of described adhesive is the 2.5-10% of described substrate gross mass.

Traditional wet papermaking method thin slice does not have special spray to add the technique of adhesive, does not generally add or only in paper making pulp, adds a small amount of adhesive.The present invention is different with it, spraying process utilizes compressed air to be fully atomized containing adhesive feed liquid, even splash is to substrate surface, for guaranteeing fully to disperse infiltration, adopt vacuum draw at the back side of spray-coating surface simultaneously, glue and feed liquid are fully penetrated, avoids substrate layering, ensure that glue spraying is even simultaneously, effectively can ensure that substrate has good structural strength (comprising dry strong and wet strong) and tensile resistance like this.
The present invention compares traditional paper process thin slice substrate and existing dry method of paper-making method thin slice substrate, maximum beneficial effect is that paper substrate structural advantage is obvious, shaping by air laid because employing longer fiber, because fiber has certain length, in unordered interfolded state, define the chaotic configuration of cubic network, then add this structure of adhesive solidification (referring to Fig. 2) by spray, therefore apparent density is low, and mass per volume is generally at 0.1-0.05g/cm
3, Filling power is about the substrate 2-3 of traditional paper process thin slice doubly, generally reaches 12-18cm
3/ g.
The reconstituted tobacco substrate of manufacture of the present invention is the same with the substrate of traditional paper process manufacture has good structural strength, and owing to employing shitosan in adhesive, substrate is made to have more excellent water resistance, measure through vertical computer tensiometer (model YT-L30), it is the highest can reach dry strong by about 40%.Therefore there is excellent machinability, add at follow-up finished product reconstituted tobacco and not easily rupture man-hour, even if the feed liquid of sole mass more than 8 times is added in tolerance, also can support finished product high-speed molding.
The advantage of substrate because of its dimensional network structure of traditional paper process manufacture compared by the reconstituted tobacco substrate of manufacture of the present invention, there is excellent tensile resistance, the percentage elongation (not breaking the elongation that under prerequisite, paper substrate is maximum) measured under its saturated water suction state with vertical computer tensiometer is maximum can reach 9.8%, generally fluctuates within the scope of 6-10%.And under the saturated water suction state of traditional paper-process reconstituted tobacco its percentage elongation generally about 2%, in addition the cubic network of its porous has also ensured that it can hold at most the powder adding himself quality 2.5-3 times, for the reconstituted tobacco manufacture of high-quality provides favourable technical support.
Common dry method of paper-making method is eliminated electrostatic and can have been come by directly adding antistatic additive, the present invention is for eliminating electrostatic, have employed the design that antistatic knot closes antistatic net, this design effect is good, cost is low, installing space is little, without any pollution, also obviously can meet the double requirements of smoking property of cigarette quality.
Because the present invention adopts dry method of paper-making legal system for reconstituted tobacco substrate, carry out molding bonded by adhesive, the selection of adhesive equally also will meet the security of cigarette additive and the not obvious requirement affecting product sucking quality simultaneously.
