Description
Technical field
The present invention relates to a tobacco articles and processing technology thereof, particularly manufacture technology and the method for the substrate of reconstituted tobacco with dry method of paper-making law technology.
Background technology
Reconstituted tobacco is weighed again and is organized tobacco leaf, homogeneous tobacco leaf.Mainly by offal fragment, offal or discarded tobacco leaf, add string, adhesive and other additive and form.Reconstituted tobacco now has been widely used as cigarette products as the tobacco product raw material.Utilize tobacco low order raw material to laminate to have that cost is low, fillibility good, and can reduce in the flue gas characteristics such as tar content, make and start from the 1950's.Manufacture method mainly contains paper process, thick slurry method and three kinds of methods of roll-in method, because thick slurry method, roll-in method technique fall behind and many reasons of product quality aspect relatively, there is no to be widely used and to be eliminated gradually, basically be widely used now the paper process technology and produce the reconstituted tobacco substrate.
Paper process; traditional paper process exactly; with tobacco powder offal, offal or abandoned tobacco raw material elder generation water extracted tobacco extract; after the extraction water-insoluble matter add/or do not add and enter paper machine after natural fiber is made slurry; begin to take shape gauze, be after the oven dry substrate of reconstituted tobacco (water-soluble extract is applied to substrate in the subsequent handling in the lump again with other additives after concentrated).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.Because complex process, energy consumption is high, and equipment investment is large, is fit to large-scale production.
By research and the use in twenty or thirty year, this technology has obtained sufficient development and raising, and is extensively used on the production of cigarettes both at home and abroad.But the defective that also has several aspects: the one, adopt traditional paper technology, produce large amount of sewage in the production, belong to serious pollution production technology, sewage disposal and blowdown presssure are very large; The 2nd, the fragrant loss of tobacco material smoke and cigarette in process obviously, the offal that it is used and tobacco chippings need to be passed through lixiviate in water, water-soluble tobacco ingredient wherein has significantly sacrificing in concentration process, and that insoluble tobacco material loses in defibrination process subsequently is also very obvious, the smoke cigarette of the reconstituted tobacoo of consequently producing is fragrant not enough, jealous and the assorted gas of non-tobacco is outstanding, affects sucking quality; The 3rd, the paper substrate structure that this method is produced hardens, smooth surface, load capacity is not enough, the spreading rate of present 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 defective that must cause reconstituted tobacoo of content of the few paper substrate of the tobacco material of interpolation; The 4th, the structural capacity of the paper substrate of traditional paper process manufacturing is provided by the hydrogen bond between the fiber, it is wet very poor by force although structural strength is good, the stretch-proof ability of paper substrate a little less than, limited the speed in the follow-up coating process, easily disconnected paper and breaks in production, stretch-proof defective and wet strong defective not only affect production capacity but also cause production technology unstable.For the problem that wet papermaking method reconstituted tobacco substrate exists, the demand reconstituted tobacoo that falls especially at home Jiao for satisfying Harm reduction techniques uses under the overall background that more and more comes into one's own, and is all exploring new tobacco sheets by paper making method substrate manufacturing technology.
In seek solving more above-mentioned problems, patent ZL00808488.2 has proposed the method for the manufacturing thin slice of similar manufacturing nonwoven.The load that is made into the cloth shape with string is first held layer, holds layer in load and adds tobacco powder.Because string and tobacco powder do not have caking property, must when adding tobacco powder, add simultaneously pulverous adhesive, the heating pressurization makes it to become one behind the humidification.Also after adding tobacco powder, add again a nonwoven layer that is formed by string as the cover layer by design, make like this flake structure of the sandwich one deck tobacco powder of a kind of two fibre layers offal.Heating is pressurizeed after needing humidification in the forming process of this thin slice, makes the bonding straticulation structure of string and tobacco powder offal.There is obvious defective in this design, and main manifestations is: structural slab is real, and its density is larger, is about 0.73g/cm
3, the filling value is little, compares with existing wet papermaking method thin slice, does not have clear superiority; Adhesive strength is little, and the glue of its interpolation is to be mixed in the tobacco powder offal, and the bonding force between tobacco powder offal and the plant fiber layer is very weak, shows as the tab strength defectiveness; The tobacco powder offal is a pantostrat basically, and toughness is inadequate behind the gummed, easy dry linting in the thin slice cutting process, and useful value is subject to serious limitation in actual production; This outer adhesive use amount is large, has also affected to a certain extent cigarette odor-absorbing.Compare with traditional papermaking-method reconstituted tobaccos, its advantage is also not obvious, 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 has 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 law technology combine in fact.Specific practice is the abandoned tobacco raw material, i.e. the water such as offal, offal extraction is continued to employ after extract is concentrated, obtains mixed slurry extracting slag and adding the wood pulp cellulose defibrination again, and this part technique is fully with traditional wet papermaking method technique; Then the slurry oven dry is made the dry pulp powder about the 80-200 order, adopt wind to deliver to pair roller place, moulding position, form the powder thin layer through extruding, spray again the adhesive of trace at the thin layer that forms, be coated on equably concentrated extract on the substrate again, baking becomes the finished product of reconstituted tobacco to the mass dryness fraction of setting.This part technique is with the technique of thick slurry method.The starch order number that the method gets by defibrination infers that accordingly the moulding mesh of its air lay must be less than 200 orders between 80-200 orders, its air permeability certainly will cause the difficulty of moulding.Because tiny is Powdered, be deposited on the forming net behind the air lay, gap between powder is less, denser, add that spraying glue and extract can further increase the packing of substrate, though its fluffy degree and bulk density do not mention, comparing the wet papermaking method does not have very large advantage at loading, because there is not good fluffy degree not have good filling capacity.Because of 80-200 purpose powder, fiber is shorter complete in a small amount of adhesive and extract bonding in addition, the intensity of this thin slice, the especially wet serious problems that exist by force.Just because of the method in the significant deficiency that the moulding design exists, has seriously been limited to and has been used the method to produce qualified reconstituted tobacco.
All still there is the substrate strong defective that wets in the substrate that present traditional paper process technology is made the reconstituted tobacco that reconstituted tobacco substrate or similar patent 200810030146.5 and patent ZL00808488.2 mention, follow-up process industrial art performance is poor, filling capacity is not enough, the potentiality of the tobacco material of load are little, and the sucking quality defective, limited the use of reconstituted tobacoo in cigarette.
Summary of the invention
For above-mentioned problems of the prior art, the inventor attempts adopting Paper DryForming Technology to produce the reconstituted tobacco substrate first.But the inventor finds: adopt dry method of paper-making method to be used for the reconstituted tobacco production process and need to overcome a large amount of static that preparation process produces; In addition, it is to be good for by hydrogen to carry out combination 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 is not add adhesive), and the inventive method attempts adopting Paper DryForming Technology to make substrate, for making the effective combination of substrate, design adds adhesive in the substrate surface spray, but tobacco business has high requirements to Choosing of adhesive, the requirement of adding security is not only arranged, and the adhesive that requires to add can not obviously affect smoking quality.In addition, how in the situation of using a large amount of adhesive to add, also need further to satisfy the requirement that substrate is done strong requirement and prior wet strong and stretch-proof ability, make substrate that good structural strength not only be arranged, and after in follow-up process, having absorbed the solution that is several times as much as the substrate sole mass certain wet strong and stretch-proof ability can also be arranged.By force wet and stretch-proof ability is a great problem that present reconstituted tobacco substrate preparation faces preferably.The prepared reconstituted tobacco substrate of the present invention inventor is through for many years repeatedly research and development, success overcome above-mentioned technical barrier, and first successful employing dry method of paper-making method manufacture obtain having than high humidity by force, the reconstituted tobacco substrate of stronger stretch-proof ability, high load capability, high filling value, excellent machinability.
