Double-grid paper making method for producing tobacco sheet

Abstract

The invention discloses a method for producing tobacco flakes by a double-net papermaking method, in which crushed tobacco, tobacco dust and soot are ground into smoke powder of 80-100 mesh and ultrafine smoke powder of 120-800 mesh; tobacco stems are soaked in water for 1-2 After 1 hour, the extract is concentrated to 15-25°Be', and 120-800 mesh ultra-fine tobacco powder accounting for 5%-30% of the weight of the concentrated solution is added to obtain a sheet coating solution; the solid matter after extraction of tobacco stems is defiberized and pulped , mixed with the added fiber pulp that has been defiberized and pulped, divided into two parts and made into two parts on the Internet; spread 80-100 mesh tobacco powder evenly on the tobacco stem-added fiber wet base sheet formed by one of the paper machines, and then Cover the wet base sheet formed by another paper machine on it to form a composite wet base sheet, then press, dehydrate, and dry to obtain a composite base sheet; process to obtain the finished sheet. The method of the invention solves the shortcomings of the two-step papermaking method, the lack of aroma, the lack of smoke taste, and the outstanding woodiness and pungency of the 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 double-wire papermaking. 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 gone thro...

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
