Natural aroma-increasing harm-reducing full-particle filter stick as well as preparation method and application thereof

Abstract

The invention discloses a natural aroma-increasing type harm-reducing full-particle filter stick and a preparation method and application thereof.The natural aroma-increasing type harm-reducing full-particle filter stick is integrally formed by a functional particle material through bonding and curing, and the preparation method comprises the steps that aromatic plant powder, functional filler powder, functional essence and a hot-melt adhesive are mixed and granulated; a granular material is obtained; adding a harm-reducing functional active material on the surface of the granular material to obtain a functional granular material, and forming the functional granular material by using a full-particle filter stick forming device to obtain the full-particle filter stick. The natural aroma enhancement type harm reduction full-particle filter stick is of an integrated rod-shaped structure formed by bonding and curing particles with natural aroma enhancement and harm reduction functions, has stable network-shaped porous morphological characteristics, and can provide a complex and smooth smoke channel, smoke can be in full contact with active ingredients loaded on the surfaces of the particles when passing through the filter stick, and therefore the smoke can be effectively removed. The content of harmful ingredients such as phenol and crotonaldehyde in the smoke is greatly reduced, and meanwhile, a relatively good aroma effect is achieved.

Description

technical field [0001] The invention relates to a new type of filter rod, in particular to a full-grain filter rod which is integrally formed by bonding and solidifying functionalized granular materials and has the functions of natural flavor enhancement and harm reduction, and also relates to its preparation method and application, belonging to cigarette production technology field. Background technique [0002] Cigarette filter rods, as a filter system for cigarette smoke, play an important role in improving the quality and safety of cigarette smoking. However, the current cigarette filter rods have a single form and simple functions, and the trend of cigarette homogeneity is becoming more and more serious. Therefore, new cigarette filter rods Rod's research and development has reached an unprecedented height in the industry.

[0002] Cigarette filter rods, as a filter system for cigarette smoke, play an important role in improving the quality and safety of cigarette smoking. However, the current cigarette filter rods have a single form and simple functions, and the trend of cigarette homogeneity is becoming more and more serious. Therefore, new cigarette filter rods Excellent research and development has reached an unprecedented height in the industry

[0003] The application of granular materials in cigarette filter rods usually uses particles uniformly dispersed in acetate tow to prepare composite filter rods. On the one hand, the complex process leads to a sharp increase in cost, and on the other hand, the amount of particles used is extremely limited. Due to the "penetration effect" of particles Difficult to fully utilize

Another way of use is to concentrate the particles into the cavity with a fixed length between two cellulose acetate rods to form a ternary composite filter rod, which requires special equipment, and the amount of particles added cannot be precisely controlled and the cavity cannot be filled. The quality stability and hardness index of the rod are difficult to meet the requirements

[0004] The application patents CN201710506486X and CN2017105064874 previously submitted by the applicant relate to a filter rod with aromatizing function, which is formed by extruding particles containing fragrance ingredients with a screw extruder, and is a full-grained filter rod with aromatizing function. However, this preparation method requires particles to have high strength and density, which is not conducive to the release of aroma components, and at the same time, the interception effect of harmful components will be greatly reduced, reducing the availability of filter rods
