Description
Technical field
The invention belongs to cigarette industry reconstituted tobacco technical field, particularly by optimal control coating fluid reflux technique flow process, in conjunction with regulating concentrate concentration method, reach in production process after spreading rate and coating that effective ingredient in product is stable, the papermaking-method reconstituted tobaccos technique of the potent fruit of uniformity.
Background technology
Reconstituted tobacco is by materials such as the offal producing in Cigarette processing process, broken stalk, fragments, is processed into sheet or thread reconstituted tobacco product (being also reconstituted tobacoo) through two step method processing, recombination.Known wet type papermaking-method reconstituted tobaccos is produced traditional papermaking technology of having continued to use, tobacco material (offal, offal, tobacco powder, waste/hypo-tobacco leaf etc.) is soaked to extraction in advance, extract is for the preparation of reuse coating fluid (medicinal extract), the sizing of quenching slurry is processed rear starching to wet type paper machine fourdrinier wire, through dehydration, squeezing, drying cylinder processing, make the substrate of mass dryness fraction approximately 75%, then be paper web shape reconstituted tobacco at substrate positive and negative dip-coating reduction coating fluid drying and moulding.Reconstituted tobacco plays reducing tar and reducing harm, effectively adjusts cigarette product physicochemical property important function.Reconstituted tobacco control of product quality content comprises that substrate is manufactured paper with pulp and stoving process, coating fluid preparation and coating process etc.On the one hand, substrate is manufactured paper with pulp and oven dry, coating fluid preparation and coating process are higher to material quality and slurrying, the equipment and technology equipment degree of dependence of manufacturing paper with pulp, on the other hand, coating process difference, directly have influence on after spreading rate and coating in product that effective ingredient is stable, uniformity, these indexs are important contents that reconstituted tobacco manufacturer must control.
In conventional wet papermaking coating technique, coating fluid used mostly is the coating of stable homogeneous, and coating concentration regulates can be by adding the method controls such as coating or dilution water and stablizing coating fluid concentration.But reconstituted tobacco substrate coating process adopts immersion coating method more, and its special feature is:
(1) the material component mixing in coating fluid has three kinds at least, wherein a part is from the extract after concentrated, also be added with in addition at least two kinds of flavor matter raw materials, in many components coating fluid dip-coating process, when different component raw materials immerse substrate and are absorbed, speed there are differences, and while recycling coating fluid, in final products, the actual coating effective ingredient of adhering to is not identical with setting value;
(2) without in the coating fluid of allocating under temperature, variable concentrations, each component evaporation capacity difference in allotment and drying course is larger;
(3) soak coating method for increasing coating weight, have a large amount of coating fluids to reflux, recycling after backflow coating fluid mixes with new interpolation coating fluid.Backflow coating fluid is compared with new coating fluid, except existing the more problem of impurity, outstanding problem is that backflow coating fluid is because the substrate (1), to different component raw material absorption rate difference, causes the backflow coating fluid after repeatedly circulating to have the increasing trend of effective constituent difference compared with new interpolation coating fluid.
Known backflow coating fluid is after backflow coating fluid impurity screening, directly to pump to new system in coating fluid holding vessel with new interpolation coating fluid hybrid mode, after stirring for coating fluid with new system, be pumped to dispense tip dip-coating substrate (systemic circulation reflux type), its weak point is: because holding vessel volume is larger, based on the coating process of this systemic circulation reflux type, coating fluid becomes component ratio and more and more departs from setting value in continuous cyclic process, the utmost point is unfavorable for the steady quality homogeneous of batch products, even if constantly automatically regulate aborning coating fluid concentration, in conjunction with on-line monitoring regulation speed, substrate quantitatively and moisture, automatically control the numbers such as coating weight, applicator roll line pressure, coating fluid temperature, and according to coating fluid capacity of returns, automatically control the measures such as spreading rate, and be also difficult to ensure in card finished product and be coated with ingredient stability homogeneous, before and after single batch products, section quality differs different often.If can be real-time and Measurement accuracy holding vessel coating fluid in different component material rates add and supplement, also can solve described problem, but in fact because coating fluid in holding vessel is a dynamic systemic circulation process, Measurement accuracy is difficulty quite; On the other hand, also do not have up till now citablely to measure real-time different component material rates in coating fluid, and control different component raw material timesharing addition technology.
