Abstract
The invention belongs to the field of heating non-combustible cigarettes, and particularly relates to a heating non-combustible tobacco rod and a preparation method thereof. The tobacco rod (1) comprises a plurality of first smoking particles (2) and a plurality of adhesive particles (3), and different first smoking particles (2) are bonded by means of adhesive shells (3-2) of the adhesive particles (3). The tobacco rod of the invention contains two kinds of particles with different diameters, and the adhesive particles with smaller diameters are used as the adhesive particles to bond the tobacco particles into a whole tobacco rod. Thus, smoke is free to flow out of the tobacco particles during smoking.
Description
Technical Field
The invention belongs to the field of heating non-combustible cigarettes, and particularly relates to a heating non-combustible tobacco rod and a preparation method thereof.
Background
With the technological progress and the general improvement of health consciousness of people, the novel tobacco products show rapid development. The low-temperature non-combustible cigarette is taken as one of main products and is particularly valued by various large research institutions and enterprises. At present, the low-temperature non-combustion cigarette products in the market mainly utilize a special electric heating device to fill tobacco materials and the like, and smoke in the tobacco filling materials is volatilized through electric heating, so that smokers can obtain a smoking feeling similar to that of traditional tobacco.
The tobacco material forms in the existing low-temperature non-combustion cigarette products comprise tobacco shreds, tobacco particles, tobacco rods or tobacco blocks and the like. Among them, the tobacco rod or the tobacco block is not easily scattered because of its shape self-sustaining property. Therefore, in the cigarette production process, the cigarette is more convenient to use and package, and is more suitable for the existing cigarette rolling and connecting process.
The current preparation methods of tobacco sticks include the following two methods: (1) mixing the tobacco particles with an adhesive, and extruding and molding to obtain a tobacco rod; (2) the tobacco particles are mixed with the binder so that the outer layer of tobacco particles is wrapped with the binder layer, not extruded, but naturally bonded or slightly pressure bonded, resulting in a tobacco rod.
The above production method (1) has problems that: because the tobacco particles and the binding agent are extruded and formed, all gaps between the tobacco particles are filled with the binding agent, air-permeable gaps do not exist between the tobacco particles, and when the tobacco rod is heated and smoked, smoke in the tobacco rod cannot diffuse to the outside through the gaps between the tobacco particles. The above production method (2) has problems that: because the tobacco particles and the binder are basically naturally bonded, the outer surface of each tobacco particle is wrapped by the binder layer, although gaps which are not completely filled by the binder exist among different tobacco particles to release smoke, the binder layer wrapped by the outer surface of the tobacco particles reduces the original gaps among the tobacco particles and still blocks a part of the smoke, and the binder layer is undesirable at the place where the tobacco particles are not in contact with each other so as to be fully smoked, so that the problem of excessive wrapping of the binder exists in the scheme.
