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

Abstract

The invention relates to a method for producing the tobacco sheet via dual-mesh paper making method, which comprises that preparing the tobacco slag, tobacco powder and ash via grinding machine to the tobacco powder at 80-100 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, to be divided into two parts to be shaped via the meshes; spraying the tobacco powder at 80-100 deals on the base sheet of one paper machine, and covering this base sheet via another wet base sheet produced by another paper machine, to obtain the composite wet base sheet; 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 paper-making tobacco sheets by a double-wire 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...
