Abstract

The invention discloses a preparation method for a cigarette core material of a heat-not-burn cigarette. The preparation method comprises the steps of raw material pretreatment, mixing, material distribution, pre-pressing, multi-stage coining, drying and rolling. The cigarette core material for the cigarette core material can be integrally formed without carrier coating and is smooth in surface, high in density and high in heat-conducting property; meanwhile, the smooth surface and high density of the core material can reduce thermal resistance problems caused by surface and internal gaps of the core material to the greatest extent; and by adding a heat conduction material, the heat conduction performance of the core material can be improved, efficient smoking of the formed heat-not-burn cigarette and effective volatilization of smoke are guaranteed, and a heat-not-burn cigarette product has good sensory quality and user experience.

Description

technical field [0001] The invention belongs to the technical field of heat-not-burn cigarettes, in particular to a method for preparing a core material of heat-not-burn cigarettes. Background technique [0002] Under the background of increasingly severe tobacco control environment, the sales of traditional tobacco products have stagnated or even declined in some developed and developing countries. With the general improvement of people's health awareness and the rapid development of smart microelectronics technology, new tobacco products The development of products is developing in a blowout style. Representative non-guided tobacco products on the market mainly include heat-not-burn tobacco products and smokeless tobacco products. As a major product in new tobacco products, heat-not-burn cigarettes have generally been valued by tobacco companies in their research and development. In the prior art, the core material of heat-not-burn cigarettes adopts a coating process. Th...
