Method for preparing sectional aerosol generating matrix rod in intermittent spraying manner

Abstract

The invention discloses a method for preparing a sectional aerosol generating matrix rod in an intermittent spraying manner, which comprises the following steps: (1) taking anti-seepage cigarette paper, flatly laying the anti-seepage cigarette paper on a conveyor belt, then flatly laying tobacco particles on the anti-seepage cigarette paper, and running the conveyor belt at a fixed speed; (2) spraying an adhesive to the tops of the tobacco particles intermittently by a spraying head, so that the tobacco particles on the anti-seepage cigarette paper have sizing areas, non-sizing areas and sizing areas which are arranged at intervals; and (3) rolling the tobacco particles wrapped by the anti-seepage cigarette paper by a conveying belt downstream cigarette folding and rolling device to obtain a sectional type aerosol generating matrix rod strip, and then cutting to obtain the sectional type aerosol generating matrix rod. The method comprises the following steps: firstly, adopting a spraying sizing method to realize partial sizing on the surfaces of tobacco particles and ensure the release of aerosol after the tobacco particles are heated, further, adopting intermittent spraying sizing to prepare the sectional aerosol generating matrix rod with short rod sections formed by bonding the sized tobacco particles at two ends and the middle scattered particle section formed by non-sizing tobacco particles. In this way, the short rod sections at the two ends can guarantee that the tobacco particles which are not bonded in the middle do not fall off and scatter, and the tobacco particles which are not bonded in the middle guarantee the axial ventilation capacity, porosity and smoke amount of the cigarette core rod.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn cigarettes, in particular to a method for intermittently spraying a segmented aerosol-generating matrix rod. Background technique [0002] As consumers pay more attention to health issues and demand for personalized experience of cigarette products, the tobacco industry continues to respond to the upgrading of consumer demand and develops various smoking products with reduced tar and harm. Among them, heated cigarettes can provide a healthier smoking experience while satisfying consumers' sensory needs for cigarette products because their cigarette heating methods are different from traditional cigarette products. [0003] The smoking material of granular heating cigarettes is bulk smoking particles. In the prior art, since the bulk smoking particles cannot be fixed, they must be filled into the outer tube by filling, and both sides of the smoking particle section need to be sealed Paper an...

Problems solved by technology

The problems of the smoke core rod prepared by this method are as follows: 1. Since a large amount of adhesive is added in the stirring process, after cooling, there is also a gap between adjacent tobacco particles in the smoke core rod after cooling. Adhesive, which leads to low porosity of the smoke core rod and small axial air flow; 2. If in order to avoid the first problem, add less adhesive directly during the mixing process, which will lead to stickiness The dispersion of the agent is uneven, and the tobacco particles without sizing on the surface are adjacent to each other, which leads to the failure of bonding and the problem of scattered smoke particles; 3. Another more critical problem is that adding a large amount of adhesive will also cause A large amount of adhesive is applied on the surface of each tobacco particle, which seriously affects the release of aerosol after the tobacco particle is heated. In fact, the purpose of sizing is only to bind the scattered tobacco particles, but it is not expected that the tobacco Particles are also sizing where they do not bond, affecting aerosol release
