Embodiment 1

[0028] The present invention shows a method for preparing tobacco material suitable for heating non-burning tobacco products, comprising the following steps:

[0029] (1) Preparation of tobacco powder: after adjusting the moisture content of the tobacco raw material to 15%, place it in a closed system and heat it at 150°C for 1 hour; A particle diameter of 0.08mm is filtered to obtain tobacco powder; the tobacco raw material is flue-cured tobacco.

[0030] (2) Preparation of tobacco extract: Extract tobacco raw material with ethanol aqueous solution, after leaching finishes, solution is separated with tobacco, obtains tobacco extract, concentrates after this extract is evaporated to remove ethanol under reduced pressure, Obtain tobacco extract; the tobacco raw material is flue-cured tobacco; the mass ratio of tobacco raw material to ethanol aqueous solution is 1:8, the concentration of ethanol aqueous solution is 50%, the extraction temperature is 30° C., and the extraction ti...

Embodiment 2

[0040] The present invention shows a method for preparing tobacco material suitable for heating non-burning tobacco products, comprising the following steps:

Abstract

The invention discloses a preparation method of a tobacco material applied to heating non-burning tobacco products. The preparation method comprises the following steps: (1) preparing tobacco powder;(2) preparing tobacco extract; (3) preparing a dispersing auxiliary solution; (4) dispersing a heat conduction material; (5) adding a flame retardant into the tobacco extract obtained in the step (2)according to a mass ratio of 1:1 to 1:4; (6) preparing a mixed system; (7) feeding the mixed system obtained in the step (6) into a single screw extruder to be continuously mixed, and injecting a foaming agent CO2 to perform foam extrusion molding, enabling the extrudate to present a porous structure, drying the extrudate, and cutting the extrudate into a filamentous tobacco material by a cutter after drying, thereby obtaining the tobacco material applied to heating non-burning tobacco products. The preparation method disclosed by the invention solves the problems that the tobacco quality is low, the smoke release property is poor and the flame retardant property of the tobacco is poor, is simple in preparation process and low in cost, and has excellent industrialization prospects.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a method for preparing tobacco material suitable for heating non-burning tobacco products. Background technique [0002] Heat-not-burn tobacco products originated in the 1980s, and have a history of nearly 30 years since the products came out. After continuous technological innovation and product promotion, it has become one of the important types of new tobacco products. The smoke produced by this type of product is relatively close to that of traditional cigarettes, and the sidestream smoke and some harmful components are significantly reduced, making it have certain market potential. Therefore, related technologies have become a research hotspot for foreign tobacco companies. In recent years, with the continuous increase of tobacco control efforts, foreign tobacco companies have continuously increased research and development efforts on heat-not-burn tobacco products as an al...
