Abstract
The invention disclose a method for reducing difference on two sides of paper-making reconstituted tobacco, which adopts the moistening manner of quantitatively spraying atomized tap water on the back of a coated substrate through an atomizing nozzle to increase the liquidity of coating liquid on the back of a sheet, and prompt the coating liquid on the back to further permeate to the front, and the distribution difference of coating weight on the front and the back is reduced, and uniformly front and back coating weight of the sheet is achieved. The method has less input, simple control, and obvious effect. The vertical height between the atomizing nozzle and the sheet is 250 to 350 mm; the centre line of the nozzle is vertical to an oblique plane of the sheet; the mist granularity is not greater than 300 micrometers; and the spraying volume for the sheet is 150 to 250 g per square meter.
Description
Technical field
The present invention relates to a kind of reduction papermaking-method reconstituted tobaccos two sides difference method, be specially by the spraying humidification mode, it is poor because positive and negative coating weight inequality causes drying finished product thin slice two sides, back to reduce substrate coating back, genus cigarette industry reconstituted tobacco technical field.
Background technology
Reconstituted tobacco is materials such as the offal that will produce in the cigarette process, broken stalk, fragment, passes through technical finesse and reconfigures and be processed into sheet or thread reconstituted tobacco product (also being reconstituted tobacoo).Known reconstituted tobacco production method is mainly the wet type paper process, its characteristics are continued to use traditional papermaking technology, tobacco material (offal, offal, tobacco powder, waste/hypo-tobacco leaf etc.) soaked to quench get, quench and get liquid for the preparation of medicinal extract, the sizing of quenching slurry back and a small amount of plus fiber are mixed into the pulp-water of proper ratio, starching is to fourdrinier wire, through dehydration, squeezing, big baby dryer, making the substrate of mass dryness fraction about 75%, is paper web shape reconstituted tobacco at substrate positive and negative dip-coating reduction coating fluid (medicinal extract) and drying and moulding again.Because offal, fiber content is few in the waste/hypo-tobacco leaf, non-fibre fractionation is more, offal, the tobacco powder slurry is non-fibrocyte component substantially, slurry by this class feedstock production, it is characterized in that: coarse staple fibre bundle many (even having thick fibre bundle to exist), the fibrocyte wall thickness, beating degree is low, be unfavorable for improving the substrate pliability and increase the substrate bulk, be unfavorable for increasing spreading rate, when drying, adopts substrate capable and experienced dry mode for this reason, evaporate the moisture content in the substrate rapidly, but, there is larger difference in roughness between the substrate positive and negative that this fiber characteristics and capable and experienced drying process are manufactured paper with pulp out, just difference problem in two sides is outstanding, substrate two sides difference causes coating again, it is poor that the two sides appears in oven dry back finished product thin slice, comprises the color distortion on apparent, substantial coating weight difference etc.Therefore, reducing even eliminate the two sides difference is to improve an important content of reconstituted tobacco end product quality.
Existing dip-coating coating process is that the substrate with mass dryness fraction about 75% passes a pair of rubber roll of rotation in opposite directions, have between the place's of passing roll surface～coating fluid (medicinal extract) that 200mm is high soaks and is attached to (referring to accompanying drawing 1) on the substrate, become the thin slice of humidity about 40% after the dip-coating, it simultaneously is positive setting substrate subsides vat, another side is reverse side, because substrate adopts capable and experienced dry mode to improve bulk, the positive smoothness of substrate is higher than reverse side before the dip-coating, the reverse side coating weight is greater than positive coating weight, in order to reduce the coating weight difference, by copper mesh with dip-coating after thin slice cause setting height along the fixed length inclined-plane, level enters the drying baker drying again, this moment, coating fluid was because of the gravity effect, will be from thin slice reverse side (upper surface) infiltration downwards, it is poor to have reduced the two sides to a certain extent, but because of the coating fluid concentration limit, the two sides difference can't reduce to predetermined value.
Reducing the two sides difference method in the known wet papermaking process comprises the control fibre composition, adjusts wet end furnish, improves beating degree, increases small article size fillers, increases the forming net number of plies, and control oven dry speed, utilize calender to carry out press polish processing etc., these methods (particularly improving beating degree, control oven dry speed and press polish mode) can not all refer in the reconstituted tobacco substrate papermaking process.Do not find disclosed about reducing or eliminate the report of reconstituted tobacco finished product two sides difference document or patent yet.
Summary of the invention
The objective of the invention is to ask a question at background technology, a kind of reduction papermaking-method reconstituted tobaccos two sides difference method is disclosed, be by in the quantitative spraying humidification mode of thin slice reverse side, increase thin slice reverse side coating fluid flowability, impel the reverse side coating fluid further to the front infiltration, reduce positive and negative coating weight difference in distribution as far as possible, it is poor to have reduced finished product thin slice two sides, drop into and save, control is simple, and effect is remarkable.
Technical scheme of the present invention is a kind of reduction papermaking-method reconstituted tobaccos two sides difference method, it is characterized in that: be to adopt the reverse side of atomizer after the substrate coating quantitatively to spray atomizing running water humidification method, adjust thin slice positive and negative coating weight uniformity; Its beneficial effect is: oven dry back thin slice has been eliminated two sides difference phenomenon substantially.
Aforesaid a kind of reduction papermaking-method reconstituted tobaccos two sides difference method, it is characterized in that: described atomizer is from thin slice vertical height 250～350mm, nozzle centerline is vertical with the thin slice inclined-plane, spray film granularity ≯ 300 μ m, every square metre of thin slice spray amount 150～250g.
The invention has the beneficial effects as follows: adopt upper surface quantitatively to spray atomizing running water method, before thin slice enters baking oven, impel the coating fluid that is positioned at the thin slice upper surface further to infiltrate into thin slice inside, reduced the coating weight that is positioned at the thin slice reverse side, thereby make that thin slice positive and negative coating weight is more approaching, be conducive to eliminate finished product thin slice two sides difference phenomenon.

Mark in the accompanying drawing: 1-drying baker, 2-spraying back thin slice, 3-frame, 4-atomizer, 5-thin slice, 6-substrate, 7-liquid-bearing pan, 8-coating rubber roll, 9-polyester webs, 10-baby dryer, 11-big drying cylinder, 12-copper mesh.
The specific embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing to technical scheme:
As shown in Figure 1, existing dip-coating coating process is that the substrate 6 with mass dryness fraction about 75% passes a pair of rubber roll 8 of rotation in opposite directions, have between the place's of passing roll surface～coating fluid (medicinal extract) that 200mm is high soaks and is attached on the substrate 6, coating back thin slice 5 along the inclined-plane upwards to setting height again level enter drying baker 1 drying, because substrate 6 has adopted at vat 11 and has carried out capable and experienced dry mode, the effect of little cylinder 10 only limits to debugging mode, it is poor to be unprofitable to eliminate smoothness for two sides, so substrate 6 namely exists the positive and negative smoothness poor before the coating, though will be when the fixed length inclined-plane upwards causes drying baker by copper mesh 12 at thin slice after the coating 5, coating fluid permeates downwards from being coated with back thin slice 5 reverse side (upper surface) because of the gravity effect, it is poor to have reduced the two sides to a certain extent, but because of the coating fluid concentration limit, the two sides difference can't reduce to predetermined value, causes drying the back positive and negative difference and further strengthens.
As Fig. 2, shown in Figure 3, for the embodiment of the invention is sprayed atomizing running water humidification scheme schematic diagram.Atomizer 4 is installed on the frame 3 among the figure, and its position is in thin slice 5 tops, coating back, drying baker 1 front portion, and atomizer 4 is from thin slice 5 vertical heights 250～350mm, and nozzle centerline is vertical with thin slice 5 inclined-planes.
Set the spray film granularity ≯ 300 μ m that sprayed by atomizer in the work, set every square metre of thin slice spray amount 150～250g.Because spray film has compensated thin slice 5 upper surface coating moisture content, spraying back thin slice 2 enters the baking oven front and back stage, impel the coating fluid that is positioned at spraying back thin slice 2 upper surfaces further to infiltrate into the inside of spraying back thin slice 2, reduced the coating weight that is positioned at spraying back thin slice 2 reverse side, thereby make that spraying back thin slice 2 positive and negative coating weights are more approaching, eliminate finished product thin slice two sides difference phenomenon substantially.
Below by reference to the accompanying drawings the specific embodiment of the present invention and finished product thin slice measurement result are described; but these explanations can not be understood that to have limited scope of the present invention, and any change of carrying out on claim of the present invention basis all is protection scope of the present invention.
