Tobacco sheet and production method thereof

Abstract

The invention provides a tobacco sheet and a production method thereof. Waste tobacco stems, tobacco bifurcations, tobacco ends and bottom tobacco are used as raw materials, tobacco leaves and tobacco skeletons are respectively subjected to NCRMP and high-consistency pulping, then pulp mixing operation is carried out, and coating liquid is prepared through tobacco leaf extraction liquid, so that chemical residues and miscellaneous gas of chemical wood pulp are removed completely, good compatibility is realized, bulk density and flammability are improved, a filling rate is increased, and the quality of the tobacco sheet is improved, therefore, quality stabilization is facilitated; plasticity is high, physical properties and internal chemical indexes of the sheet can be regulated manually according to actual demands, the freedom degree for regulating a cigarette formula is high and improvement of quality of cigarette is facilitated; the problems of shortage of raw materials for producing the tobacco sheet and tobacco stem waste are solved, meanwhile, the cost of the tobacco sheet is reduced greatly and profound social significance and extremely high economic benefits are realized.

Description

technical field [0001] The invention relates to the field of tobacco sheet processing, in particular to a tobacco sheet and a production method thereof. Background technique [0002] As an important means of reducing harm and tar in cigarettes, compounding tobacco sheets has become the development direction of the domestic and foreign cigarette industry. The existing paper-making tobacco sheet is a production method in which tobacco stems, tobacco powder and wood pulp fibers are used as raw materials to manufacture substrates and apply coating solutions. Since tobacco stems and tobacco dust pulp account for more than 90%, and the pulp yield of tobacco stems and tobacco dust is extremely low, the amount of tobacco stems and tobacco dust in cigarette production is limited, which seriously restricts the output of tobacco sheets. As a result, the amount of added tobacco flakes in my country's cigarette production is less than 10%, which is far behind the 25-35% added amount of ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a tobacco sheet and its production method, which not only solves the shortage of raw materials for tobacco sheet production, waste of a large number of tobacco stalks, cigarette branches, cigarette butts and bottom tobacco, and pollutes the environment, but also has stable quality and good compatibility of tobacco sheet , low cost, small investment in production equipment, convenient for large-scale production
