Tobacco raw material pulping process of tobacco sheets prepared by papermaking method

Abstract

The invention discloses a tobacco raw material pulping process of tobacco sheets prepared by a papermaking method, belonging to the production technical field of tobacco sheets prepared by the papermaking method. The tobacco raw material pulping process of the tobacco sheets prepared by the papermaking method adopts the following process conditions: solid-liquid separated solid phase tobacco raw material is subjected to low consistency pulping to lead the tobacco raw material to become size which can meet papermaking requirements, the concentration of the solid phase tobacco raw material in the size is 4+ / -0.5%. The low consistency does not need to improve the concentration of the supplied material, and directly conveys the solid phase raw material to a pulping device in a mill via a pump. The process of the invention effectively simplifies production process flow, increases half-finished quality stability, and improves tobacco sheet quality, thus ensuring that the tobacco sheets can be well compatible with the natural tobacco leaves.

Description

technical field [0001] The invention belongs to the technical field of paper-making tobacco sheet production, and in particular relates to an improved beating process in the pulping section of the tobacco raw material production process. Background technique [0002] Tobacco sheet is a sheet-shaped tobacco regenerated raw material that meets the requirements of cigarette formula by processing and reorganizing tobacco waste such as tobacco stems, tobacco powder and low-grade tobacco leaves discarded in the cigarette production process. Tobacco sheet is mixed with natural tobacco leaves in a certain proportion Blended into cigarettes. Its main significance is: to improve the utilization rate of tobacco raw materials, make full use of the waste in the cigarette production process; reduce the tar content of cigarettes, improve the grade of cigarettes, and at the same time achieve the purpose of reducing tar and harm. Due to the full utilization of discarded tobacco stems, tobac...

Problems solved by technology

[0005] 1. The production process is complex: due to the use of short fiber viscous beating, the concentration of the slurry in the beating equipment generally needs to reach a dryness of about 20%, so it is necessary to set up an equipment squeezer to increase the dryness, which makes the production process complicated

[0006] 2. It is difficult to guarantee the beating quality: when the tobacco raw material has a dryness of about 20%, the fluidity is poor, and the flow rate into the beating equipment is difficult to guarantee. Therefore, it is difficult to control the beating degree of the pulp after passing through the beating machine. The copying of the sheet brings difficulties, thus affecting the quality of the sheet

[0007] 3. The quality of the sheet cannot meet the requirements of the cigarette process: the tobacco sheet beaten by the above method, due to the mutual friction and extrusion of the tobacco raw materials at high concentrations, the tobacco raw materials are shredded, broomed, and crushed seriously, and the produced tobacco sheet has The shortcomings of low bulk, poor absorbency, and poor softness cannot be well compatible with natural tobacco leaves
