Abstract
A kind of novel tobacco sheet of the present invention and its production method, it is that to use the cigarette stalk homologous with its tobacco leaf and bottom cigarette be raw material, the wood pulp or bamboo pulp fiber of chemical method is not used, does not have miscellaneous gas, compatibility is good, and the more existing reconstituted tobacoo such as sense organ, bulk density, filling rate and flammability has improvement；The quality of reconstituted tobacoo is not only increased, and plasticity is strong, can carry out artificial regulatory to its physical and chemical index according to actual needs, and the cigarette composition adjustment free degree is big, is easy to improve cigarette quality；Solve that reconstituted tobacoo raw materials for production are in short supply and cigarette stalk and bottom cigarette de-referencing problem, the cost of reconstituted tobacoo is greatly reduced, with high economic benefit and far-reaching social effect.
Description
Technical field
The present invention relates to the manufacture field of reconstituted tobacoo, a kind of particularly production method of novel tobacco sheet.
Background technology
Compatibility reconstituted tobacoo as Harm reduction techniques tar reduction important means, at home and abroad cigarette industry is commonly used.State
The average addition of reconstituted tobacoo is 5.5% in inner wrap strip industry cigarette, and the famous brand cigarette such as external 555, Marlboro and camel
The addition of middle reconstituted tobacoo is up to 25-35%. therefore the market development space of domestic reconstituted tobacoo is very big.Existing paper process
Reconstituted tobacoo is that slurrying adds wood pulp cellulose behaviour to make substrate after being extracted using offal, smoked sheet and offal, spreads offal, smoked sheet and cigarette
The method dried after the coating fluid that the extract at end is prepared.In order to improve the quality of reconstituted tobacoo, or even offal is ground into cigarette
Powder is formulated into coating fluid, and reconstituted tobacoo production per ton needs about one ton or so of smoked sheet and offal, therefore existing reconstituted tobacoo to give birth to
Product method needs substantial amounts of smoked sheet and offal.And smoked sheet and offal amount limited (year generation smoked sheet and cigarette in domestic production of cigarettes
About 40,000 tons of last total amount), the yield of reconstituted tobacoo is seriously constrained, cause the addition of reconstituted tobacoo in China's production of cigarettes not
Foot 6%, the reconstituted tobacoo addition away from external 25-35% has larger gap.As the requirement of Harm reduction techniques tar reduction is improved constantly,
The demand for development economized on resources with recycling economy, be instead of existing offal, smoked sheet, offal and wood pulp cellulose using suitable feedstock
Raw material is tobacco sheets by paper making method major issue urgently to be resolved hurrily.China is tobacco consumption and big producer, and annual cigarette stalk yield is near
4000000 tons, about 550,000 tons of bottom cigarette, bottom cigarette and cigarette stalk bottom crust are compared with tobacco leaf than containing beneficiating ingredient potassium higher.Exploitation and tobacco leaf
Homologous cigarette stalk and bottom cigarette production reconstituted tobacoo, with great society and economic implications.A kind of " reconstituted tobacoo of the present inventor
Production method " patent No. 201510571885.5 is, using cigarette stalk and bottom cigarette producing tobacco flake in method similar to papermaking in a wet process, to solve
The good problem of compatibility of the raw material problem and reconstituted tobacoo of reconstituted tobacoo production in cigarette.In order to reduce reconstituted tobacoo life
The water consume of product, energy consumption and production cost, further improve with cigarette stalk and bottom cigarette be raw material produce reconstituted tobacoo quality, it is necessary to
Cigarette stalk and bottom cigarette is used to research and develop on the basis of producing tobacco flake in method similar to papermaking in a wet process with dry method of paper-making method production reconstituted tobacoo
Method.The production of the dry method of paper-making method reconstituted tobacoo patent CN103222677A and CN104824824A are made to solve domestic wet method
Paper method production tobacco sheet quality is low, the cigarette that the offal produced by largely adding cigarette with substrate surface in the substrate is ground into
Powder, makes miscellaneous gas of substrate production reconstituted tobacoo etc. and causes to influence the quality of reconstituted tobacoo to ask to reduce wood pulp or bamboo pulp fiber behaviour
Topic, to improve the addition of reconstituted tobacoo.But both production method tobacco powder consumptions are all up to more than the 70% of reconstituted tobacoo,
Not only it is easily caused chopping dry linting and cost of material raises problem, and national cigarette industry produces offal amount only a few kiloton per year, it is clear that
It is difficult to meet the huge offal consumption demand of the method.
The content of the invention
It is an object of the invention to provide a kind of production method of novel tobacco sheet, reconstituted tobacoo production is not only solved former
Material is in short supply, and (bottom cigarette includes that the leaf of two panels bottom of tobacco growing is pin leaf and back to back two panels leaf is for a large amount of cigarette stalks and bottom cigarette
The overwhelming majority is discarded as inapplicable tobacco leaf for lower two canopy two parts, current pin leaf and lower two canopy, and organic fertilizer is done on a small quantity) it is discarded,
Environmental pollution problem.In order to reduce water consume, energy consumption and the production cost of reconstituted tobacoo production, further improve with cigarette stalk and bottom cigarette
The quality of reconstituted tobacoo is produced for raw material, the technical solution adopted by the present invention is as follows：
A kind of production method of novel tobacco sheet, its technical scheme is shown in the production method skill of the novel tobacco sheet of accompanying drawing 1
