Preparation method for paper-making process tobacco sheet and finished product of paper-making process tobacco sheet

Abstract

The invention belongs to the field of tobacco industry and relates to a preparation method for a functional harm-reduction and tar-reduction paper-making process tobacco sheet and a finished product of the paper-making process tobacco sheet. The preparation method for the paper-making process tobacco sheet comprises the following steps of extracting and concentrating effective components of tobacco; mixing formulas; pulping and blending fibers; manufacturing paper with pulp; dipping, drying and tearing and shaping. The blending process comprises the following steps of: adding non-tobacco plant fiber pulp of which the beating concentration is 3-4 percent and the Schopper-Riegler (SR) beating degree is 18-28 to tobacco mixed fiber pulp, adding filling to a machine chest, regulating the pulping concentration to 2-3 percent by water, and evenly mixing. By the use or the combine use of the filling and the non-tobacco plant fiber pulp, the combustion state of the sheet can be improved while physical properties, such as the air permeability, the retention and the tensile strength of a paper base, are improved, i.e., harmful ingredients of smoke, such as tar and carbon monoxide of the paper-making process tobacco sheet, can be effectively reduced, and hazard indexes of cigarettes are reduced. Meanwhile, technical-economic indicators, such as the speed and the input- output efficiency of a paper machine, also can be improved.

Description

technical field [0001] The invention belongs to the field of tobacco industry, and relates to a method for preparing functional harm-reducing and tar-reducing paper-making tobacco sheets and a finished product thereof. Background technique [0002] As an effective auxiliary material for reducing harm and tar in cigarettes, paper-making tobacco flakes have been blended in a proportion of about 15% in cigarette formula, which can effectively reduce the harm index of cigarettes. With the further deepening of the national bureau's requirements for cigarette harm reduction and coke reduction, the major project of paper-making tobacco sheet technology upgrading has been established as one of the major industrial science and technology projects established by the State Tobacco Monopoly Administration. Its purpose is to promote industrial upgrading. During the period (2011-2015), major landmark achievements have been made in domestic paper-making tobacco sheets (requirements: tar re...

Problems solved by technology

[0005] In order to improve the existing paper-making method of tobacco sheet production, adding wood pulp fiber to a single variety brings obvious woody taste, oral irritation and residue to cigarettes, and alleviates the negative effects on cigarette sensory evaluation
