Problems solved by technology

This method can overcome to a certain extent the shortcomings of the thin slices produced by the above-mentioned two-step process and the lack of smoke flavor, but there are also deficiencies: (1) the addition ratio of soot is small, and in the preparation and production of thin slices, absolutely Most of the soot (finish) still has to go through the process of soaking extraction, pulping and concentration of the extract; (2) The particle size (fineness) of the soot used is relatively large, and the adhesion force when combined with the sheet slurry or substrate Smaller, the finished flakes are prone to powder drop
The disadvantages of this method mainly include: (1) In the tobacco industry, tobacco dust usually refers to tobacco leaf powder with a size below 1mm and above 60 mesh, but in the process of threshing and rebaking and cigarette production, a large amount of 1-3mm tobacco powder is also produced. Tobacco leaf fragments, according to this method, these toba

Example Embodiment

[0025] Example 1:

[0026] (1) Crush the tobacco powder (1~3mm tobacco leaf fragments) and tobacco powder (tobacco leaf powder less than 1mm and more than 60 mesh) with a grinding equipment, sieving to obtain 60-80 mesh tobacco powder, and the fineness produced is less than Tobacco powder with 80 meshes enters the second-stage milling equipment to make superfine smoke powder with 300-400 meshes; soot (tobacco powder below 60 meshes) is directly passed through the second-stage milling equipment to make superfine smoke powder with 300-400 meshes . Measure the moisture content of smoke powder and superfine smoke powder.

[0027] (2) Take tobacco stems (length 1~5cm) and add 55℃ hot water at a liquid ratio (weight ratio) of 1:4, soak and extract at constant temperature for 1.5 hours, then separate solid and liquid to obtain tobacco stem extract and solid tobacco stem Things. The tobacco stem extract is concentrated to 15°Be′ by vacuum distillation, and then 300-400 mesh superfine toba...

Abstract

The invention relates to a method for producing the tobacco sheet via improved paper making method, which comprises that preparing the tobacco slag, tobacco powder and ash via grinding machine to the tobacco powder at 60-80 deals and the ultra-fine tobacco powder at 120-800 deals; immerging the tobacco stem in water for 1-2 hours, separating the solid and liquid, concentrating the extractive solution into 15-25 degree/Be', adding the ultra-fine tobacco powder at 5-30% of the weight of concentrated solution, to obtain the coat liquid of sheet; the solid extracted from the tobacco stem is decomposed to prepare pulp, to be mixed with external pulped fiber, adjusting the density to 0.05-0.8%, to be mixed with the tobacco powder at 60-80 deals; preparing via paper machine, compressing, dewatering, drying to obtain the base sheet; immerging and coating the base sheet in the coat liquid, drying, breaking to obtain the final product. The invention can improve the smell of sheet tobacco.

Description

technical field [0001] The invention relates to a method for producing tobacco sheets in the tobacco industry, in particular to a method for producing tobacco sheets by an improved papermaking method. Background technique [0002] Tobacco flakes (also known as reconstituted tobacco leaves) are tobacco stems, tobacco fragments (1-3mm tobacco leaf fragments), tobacco dust (tobacco leaf fragments below 1mm and 60 mesh or more), The regenerated tobacco leaves are processed from soot (tobacco leaf powder below 60 mesh) and other offcuts as the main raw materials. It can be mixed with natural tobacco leaves and processed into cigarettes. There are two main purposes of producing and using the flakes. One is to comprehensively utilize tobacco leaf raw materials to reduce waste of resources; the other is to effectively reduce the amount of tar and other harmful substances in cigarettes and stabilize the quality of cigarette products. [0003] The development of tobacco sheet has go...
