A kind of production method of sandwich type paper-making method reconstructed tobacco leaf
Technical field
The invention belongs to the reconstituted tobacco technical field, be specifically related to a kind of production method of sandwich type paper-making method reconstructed tobacco leaf.
Background technology
Conventional papermaking-method reconstituted tobaccos production technology needs earlier tobacco material (offal, tobacco leaf, offal) water to be extracted, tobacco material after will extracting is then mixed non-baccy fibers such as joining wood (fiber crops) slurry through high (low) dense pulping that grinds, slurry is through the fourdrinier machine moulding of manufacturing paper with pulp, again through squeezing, preceding drying, tobacco material extract concentrate back and be coated with, after dry and cut after make papermaking-method reconstituted tobaccos.The reconstituted tobacco that this technological process is produced is subjected to the influence of factors such as tobacco material quality fluctuation bigger, and many such as the number of dropouts of raw materials in small, broken bits such as offal, and energy consumption is bigger, and utilization rate of equipment and installations is also lower.
At this situation, a kind of papermaking-method reconstituted tobaccos of similar sandwich has appearred in recent years.For example, Chinese invention patent application 200710034468.2 discloses " method that a kind of pair of net method produced tobacco sheets by paper making method ": cigarette is broken, offal, cigarette ash are worn into tobacco powder; The extraction of offal water, extract concentrate the back and add a certain amount of tobacco powder, make coating fluid; Offal extraction back solid mixes with the plus fiber slurry through slurrying, the separated into two parts moulding of manufacturing paper with pulp of surfing the Net respectively; Even spreading tobacco powder on the substrate of a paper machine making moulding therein, the wet substrate with another paper machine making moulding covers on it again, makes the thin slice finished product through squeezing, dry, coating, dry, fragment.Patent application 200810028019.1 discloses " a kind of composite papermaking method reconstituted tobacco and production method thereof ": component is set in the tobacco material water extraction of tobacco leaf and offal composition, extract mixes concentrated, slag charge mixing defibrination form slurry, manufacture paper with pulp up and down two material bed, with tobacco powder evenly add to down material bed on, the upper strata is compound on the tobacco powder layer, obtain substrate by squeezing, drying, extract is evenly coated on the substrate, made reconstituted tobacco more after drying.
Though existing sandwich type paper-making method reconstructed tobacco leaf can overcome the material quality fluctuation influence to product quality effectively, reduce consumption of raw materials, in actual production, also be difficult to guarantee intermediate core layer in length and breadth to distribute evenly, one make peace stable.And do not see good solution in the prior art as yet.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of production method of new sandwich type paper-making method reconstructed tobacco leaf be provided, with guarantee that the intermediate core layer material distributes evenly, stable.
Purpose of the present invention is achieved by the following technical programs.
A kind of production method of sandwich type paper-making method reconstructed tobacco leaf is characterized in that: adopt the mode of roller coat that the sandwich layer coating medium evenly is applied over up and down between the surface layer.
Described sandwich layer coating medium is made up of the raw material of following weight parts: 1 part of offal, 2~4 parts of water, 0.01~0.02 part of adhesive.
Also comprise 0.1%~1% part of cigarette additive in the described sandwich layer coating medium.
Described cigarette additive is preferably mailland reaction spices.
This method specifically may further comprise the steps:
1, tobacco material and non-baccy fiber raw material soak extraction 15~45min with the clear water of 8~12 times of amounts, and 60 ℃~90 ℃ of water temperatures are separated DDGS, and insoluble matter making beating back is standby;
2, DDGS is concentrated into density 1.1~1.2g/cm through vacuum
3Concentrate standby;
3, add 2~4 times clear water and account for the adhesive of offal weight 1%~2% in offal, stir, it is standby to make the sandwich layer coating medium;
4, on cylinder mould machine with step (1) the gained slurry upper layer of manufacturing paper with pulp;
5, adopt the mode of roller coat that step (3) gained sandwich layer coating medium evenly is applied over the upper layer surface, form sandwich layer; Surface layer under core layer surface is manufactured paper with pulp with step (1) gained slurry forms the sheet base through squeezing again;
6, step (2) gained concentrate is returned be applied on the sheet base, drying, divide and cut into required sandwich type paper-making method reconstructed tobacco leaf.
Can also further add 0.1%~1% cigarette additive in the step (3) stirs.
The present invention has following advantage with respect to prior art:
1, earlier the tobacco leaf smalls is modulated into the coating medium of pasty state, adopts the mode of roller coat to combine again, thereby guaranteed uniformity, the stability of intermediate core layer distribution effectively with surface layer up and down;
2, the prescription of surface layer, sandwich layer and consumption can be regulated flexibly, satisfying different product function or client's needs, characteristics such as " reproducing property ", " regroup " of reconstituted tobacco, " artificial controllability " are fully played out;
3, method is easy, with low cost, prepared using is abundant, has improved the service efficiency of tobacco material, and the energy-saving and emission-reduction of reconstituted tobacco production are had positive role.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail, but they are not limitation of the invention.
Embodiment 1
Produce sandwich type paper-making method reconstructed tobacco leaf.Take by weighing 570kg offal, 380kg tobacco fragment and 50kg softwood pulp, the 90 ℃ of water logging bubbles extraction with 8 times of amounts separates DDGS.The insoluble matter making beating, the slurry of must manufacturing paper with pulp is standby.DDGS is concentrated into density 1.1~1.2g/cm through vacuum
3Concentrate standby.Take by weighing 20 purpose offal raw material 100kg, add the 400kg clear water and stir, add the carboxymethyl cellulose of 5kg then, be modulated into the sandwich layer coating medium.With the slurry that the prepares surface layer of manufacturing paper with pulp, the upper layer of manufacturing paper with pulp earlier evenly is applied over upper layer by applicator roll with the sandwich layer coating medium then, the surface layer down of on sandwich layer, manufacturing paper with pulp again, and squeezing at last is base in flakes.Concentrate is returned on the sheet base that is coated onto moulding.Again drying, make sandwich type paper-making method reconstructed tobacco leaf after cutting.
Embodiment 2
Repeat embodiment 1, following difference is arranged: take by weighing 540kg offal, 360kg tobacco fragment and 100kg wood pulp, with 60 ℃ of water logging bubbles extraction of 12 times of amounts.Take by weighing 40 order offal raw material 100kg, add 300kg clear water and 1kg mailland reaction spices, the back that stirs adds the carboxymethyl cellulose of 5kg, is modulated into the sandwich layer coating medium.
