Description
The present invention relates to the method for making tobacco shaping thing such as plume, in this method, when material leaves squeezer, because it inner produce steam and material is bubbled by extruding.
The manufacture method that announced on July 18th, 1984 European patent specification EP-A-013595 number and corresponding US are introduced a kind of this class No. 4510950, this method is pushed single bundle material, and the pressing materials diameter can be used for tobacco shred just.This method comprises tobacco particle and cellulosic binders and optional a kind of inserts is made into dried mix, adds water and make wet mixture in this dried mixed ingredients, pushes wet mixture then.Wet mixture contains the moisture that accounts for weight 15-50%, and the goods after the extruding also contain the moisture of 5-20%.
The similar approach of announcing on January 8th, 1986 of having introduced wet mixture like a kind of application class for European patent specification EP-A-0167370 number, the wet mixture that this method adopted is the multi beam tobacco containing substance by porous nozzle extrusion molding.The bundle bar is bonded to each other together, forms plume, has passage between whole plume.
EP-A-0167370 has also introduced a kind of method through improved shaping wet mixture.According to the method, before being mixed into wet mixture with other mix ingredients, water blending the carrying out prehydrolysis of adhesive elder generation.Yet the time of this application is only by the application time meter of European application 85304645,6 on June 28th, 1985, rather than risen by the priority date meter of this application.
It both had been applicable to multi beam extrusion process the prehydrolysis step that the application relates generally to, and also was applicable to single bundle extrusion process.The applied particular instance of the present invention will provide in this manual, but the disclosure aspect of the method detailed features of using for the present invention, can do reference with regard to two European patent explanations that has quoted the front, these two patent descriptions all are called " European patent explanation " hereinafter.
The invention provides a kind of forming tobacco object space method that contains the wet mixture of tobacco particle and bonding agent by extruding.In this method, the shaping thing because generation steam foams in the material, is characterized in that the main component of adhesive at least in when extruding, in prehydrolysis adhesive with before tobacco particle mixes by mixing with water by prehydrolysis.
The moisture that contains 15～50% weight in the wet mixture of preferentially selecting for use, rest materials is counted 5-98% by butt weight, preferentially select for use tobacco particle more than 50% to reach the fineness degree of 5 orders (4mm), 0%～60% filler reaches 350 microns fineness degree, and the adhesive of 2-40%.
Can will be by in the adhesive of prehydrolysis with being added to up to the tobacco particle that accounts for weight 5%.In addition, the part of adhesive can be mixed with tobacco particle.Sheng Xia adhesive can come hydrolysis with excessive water like this.
According to the present invention, a kind of method of preferentially selecting for use is made up of following steps,
(1) do to mix (a) 2-98%(weight) tobacco particle and fineness degree to about 5 orders, the baker moisture value be about 3% to 20% with (b) 0%～approximately 60%(weight) filler, fineness degree is to about 350 microns,
(2) prehydrolysis adds water or similar solvent by the cellulosic binders of about weight of 2% to 40%, in order to the bond properties of activated adhesive,
(3) dry mixture that is formed by step (1) mixes the wet mixture that constitutes the moisture 15-50% of being approximately with cellulosic binders by step (2) prehydrolysis, (4) wet mixture of step (3) gained is pushed under the temperature and pressure condition that wet mixture pushes become difform article, water transform in the mixture is a steam, use the shaping thing another kind of mode that foams to be thus, the part dry mixture of step (1) gained can perhaps be done the food ingredient of the same step of a part of adhesive (1) and mix with the adhesive prehydrolysis of step (2).
Here used " extrudate " this term is meant the wet mixture material after the mixing drum that arrives squeezer.
Wet mixture preferably is extruded with cylindric single bundle form.After the extruding, this Dan Shu is the cylindricality of 2 to 35 millimeters of diameter dimensions, preferably should be 4 to 25 millimeters.Another kind of alternative cross sectional shape can be shaped by suitable mould, for example ellipse or star.The plume that is shaped is cut into certain-length, and winding becomes cigarette.Another kind method also can be carried out the multi beam extruding, and each bundle bonds together and becomes tobacco shred.
The optimum content that is present in the prehydrolysis cellulosic binders in the wet mixture can change with the plain adhesive of the special fiber that uses.When only adopting the hydroxyprolyl-cellulose as unique cellulosic binders, best content should be 8% of relative weight at least, and when not containing the hydroxyprolyl-cellulose, the optimised quantity of another kind of cellulosic binders should be 10% of weight at least.When hydroxyprolyl-and another kind of cellulosic binders are share, all consumption is when 3～40% scope, and the optimum content of hydroxyprolyl-in mixed adhesive is at least 1%(weight), and other cellulosic binders are at least 2%(weight).
Adhesive can be selected from European patent specification 0167370 described material, and it comprises " compound " that refers in the explanation 0113595 of European patent.The optional material that is included in the wet mixture is that European patent illustrates described filler, alcohol, thickener.Thickener is preferably in the dried blend step and adds, but also can add in prehydrolysis step or blend step and back to back subsequently next step.
By carrying out adhesive prehydrolysis, make the wet mixture that after step (3), obtains contain 15～50% water with enough water mixed adhesives.The prehydrolysis step directly provides moisture to the adhesive material.These moisture can be strengthened the bond property of adhesive effectively, and the extruding tobacco product that is used for forming foaming.The easier suction of tobacco particle specific viscosity mixture, they are compared with adhesive and tend to absorb more moisture mixing when adding water then with adhesive is dried at first.A kind of extrudate that contains not activated, the adhesive that can not utilize fully of obvious amount is provided like this, therefore, or add excess binder or add excessive water or the both is added on do mixing in the thing so that the adhesive of q.s is activated of tobacco and adhesive, make formed product.
Extrudate must carry out drying, and water content is reduced to required level, and this level is that tobacco product includes 5-20% (weight) moisture.
The prehydrolysis adhesive has reduced the needed moisture of extruding wet mixture material.Can produce drier and more solid extrudate, tobacco does not absorb a large amount of moisture, has used big water gaging when anticipating owing to adhesive, then must borrow drying that above-mentioned moisture removal is fallen.This has equally also exempted the required specially treated equipment of non-hydrolysis extrudate that is used for humidity.
Prehydrolysis is because the total moisture of the last extrudate that generates is low, the energy that requires in the time of just can reducing their extremely required moistures of oven dry.
The prehydrolysis adhesive is not hydrolyzed with adhesive and compares, and also can provide a kind of intensity higher extrudate.Because clearly there is more prehydrolysis adhesive to be activated.
Thereby the active proportional increase of bonding agent, thereby cause bonding better and make product that higher rigidity be arranged.Adhesive by prehydrolysis, compare with the amount of non-hydrolysis compounding method adhesive therefor, finishing adhesive effect needs less adhesive, and the quantity that reduces adhesive is not only more economical, and most importantly improves the objective quality factor of final tobacco product greatly, for example, taste, sensation, fragrance, color, and flue gas quality.
Prehydrolysis adhesive be a kind of material of thick similar dough, because in some cases, for existing common mixing arrangement, this viscosity may be too high, at this moment adds in right amount to be done by the gained of step (1) that to mix thing be useful in the prehydrolysis stage in adhesive.Although the mixed thing of being dosed of doing approximately reaches half (preferentially selecting for use below 5%) of total tobacco weight and absorbs a certain amount of moisture, it had not both had the tangible moisture that influences the prehydrolysis of adhesive and do not increase material.Opposite it will be as lubricant keeping resembling the machinability of dough pledge material, miscibility and have squeezable viscosity.
Or will some the cellulosic binders material under non-hydrolysising condition be added to preparation set by step (1) do in the mixture that mixes, with the adhesive of balance prehydrolysis.Owing in prehydrolysis adhesive material unnecessary water will be arranged, this also will cause the relatively low viscosity adhesive of prehydrolysis.Then, when mixing dried mixed thing and prehydrolysis adhesive, unnecessary water is absorbed by unhydrolysed adhesive and the dried tobacco that mixes in the thing.In this alternative method, most adhesives are hydrolyzed, thus any moisture that is absorbed in the tobacco and the extrudate water content of last generation to compare gap not obvious, and the viscosity of mixed material can make it carry out extrusion operation at an easy rate.
The adhesive hydrolysis is no matter there is or do not have a small amount of dried thing that mixes of step (1), entirely carry out in common mixing arrangement.Water content is very crucial in wet mixture, if be lower than 15%, then the shearing increase of extrusion die makes and is extruded porous that thing becomes and coarse, and this can cause foam degrees unsatisfactory.Be higher than 50%(weight in water content) time, as not changing temperature, when product passed through extrusion die, the energy that is provided when generating foam will be not enough.
Can in step (1), step (2), step (3) or step (4), dose blowing agent in the mixture arbitrarily.Blowing agent preferably is selected from air, nitrogen, carbon monoxide, ammonium carbonate, aminoquinoxaline, azide, hydrazides, pentane, hexane, heptane, halogenation fluorohydrocarbon, pyrrolones, ethanol, peroxide and azo dicarbonamide.Some blowing agents wherein may need to dose acid or alkali decomposes.Blowing agent will replenish the foaming effect of water in the wet mixture, thereby water consumption is reduced.
Preferably squeezer comprises a pair of spirality squeezing roller, this device has positive-displacement, along having selected the multiple element compound material feeding mouth on the total length of its mixing chamber, the prehydrolysis in such (2) step can occur in a section of mixing chamber, then carry out the mixing of step (3) in contiguous one section, subsequent is extruding and foaming.The double helical form squeezer is compared with the single-screw squeezer can lack water, because the effect of positive-displacement has the ability to process more ropy material.Spiral Jian Feng Pinch clamp dog or forward and reverse pulpboard all are adjustable to select only composite force to go material is pushed out extruded tube.This must be controlled with joint efforts, the burnt paste to prevent mixture from being processed by transition, and at this moment product darkens, and can not foam well.But if the not enough then formation of mixture processing is that mixing is inhomogeneous, inadequate product foams.Importantly tobacco particle and selected additional ingredient must be mixed before entering feeding bin and squeezer spout equably.Feeding bin is the total starting points of a plurality of single-screw pressurizing units, and it generally is contained near the squeezer place, can provide continuous raw material sources like this.
Feeding bin receives from the material at common blender or agitator place and generally it is discharged in the metering feed device of variable velocity.The simple storehouse of discharging by gravity of bottom discharging is used in and draws off the mixing feeding in the step (3) is enough.Can be equipped with auxiliary drawing-in device according to material viscosity.
A common variable velocity metering feed device is used for wet mixture is fed forward to squeezer by the feeding bin taking-up.The drawing-in device of this variable velocity is the key of extrusion device ability.It can adjust extrusion speed.Oscillating feeder and variable velocity scroll feeder are two normally used metering feed devices.
An intermediate treatment device can be used to the prehydrolysis adhesive, adds water, adds adhesive or other material requested to generate dough shape sticky material.These materials are added to then and go in second intermediate treatment device prehydrolysis adhesive and the dried thing that mixes of step (1) step (3) gained are mixed.In this device, mix the prehydrolysis adhesive continuously and do mixed thing, and install thus wet mixture is directly fed in the squeezer cylindrical shell subsequently.
When use has the double-screw extrusion device of many spouts, a typical example is with an intermediate treatment device with the adhesive mixing of materials together, and it is delivered to first spout, the second intermediate treatment device is fed into second spout at first spout assistant place with smoking mixture and other material.Each spout rate of feeding is separately all controlled, obtain the ratio of required adhesive, tobacco and inserts etc. thus, and according to institute's water requirement, at first add water in the prehydrolysis adhesive, next is when carrying out extrusion operation, is keeping moisture on the recipient total length at the 15%(baking oven) more than.
The sensor that is used to detect extrudate pressure in the recipient can be placed along the squeezer cylindrical shell.Corresponding water entry device also can be equally along the cylindrical shell configuration, can add water so that control moisture when needs, for example 15% above moisture value or keep required minimum moisture to prevent mixture and burn or to cause high shear force.
When using single spout squeezer, adhesive can be at first in an intermediate treatment device by prehydrolysis.Tobacco is fed in the intermediate treatment device after filler and unclassified stores are done in an independent device and mixed and mixes then, and mixed wet mixture directly is fed in the recipient.
