Description

Hollow filter stick loaded with functional parts and preparation device and method thereof

Technical Field

The invention relates to the field of cigarette filter stick preparation, in particular to a hollow filter stick loaded with functional parts and a preparation device and method thereof.

Background

With the emphasis of consumers on health problems and the improvement of the demand on the personalized experience of cigarette products, the tobacco industry continuously responds to the demand upgrade of consumers and develops various smoking products with tar and harm reduction. The heating cigarette is different from the traditional cigarette product in the cigarette heating mode, so that the cigarette can meet the sensory requirements of consumers on the cigarette product and provide healthier smoking experience.

Existing aerosol generating articles include a smoking segment, a support segment, a cooling segment, and a filter segment, wherein the support segment, the cooling segment, and the filter segment may use filter rods in the form of tows, typically cellulose acetate tow filter rods (cellulose acetate is hereinafter referred to simply as "acetate"), which can filter harmful components in the smoke. The solid filter stick has the characteristic of high interception rate, the interception rate of smoke needs to be reduced in the design of heating cigarettes, and a better method in the industry is to make the filter stick into a hollow filter stick.

At present, the production of hollow filter sticks basically adopts the mode that a rigid rod is additionally arranged at the rear end of a horn mouth of a conventional filter stick forming machine for converging, so that a hollow structure is formed at the position occupied by the rigid rod after acetate fiber tows are converged.

With the continuous upgrading of cigarette flavoring technology, each section of the cigarette gradually has flavoring requirements, and particularly for the novel tobacco product heating cigarette, the supporting section is usually an acetate fiber hollow filter stick. The section is close to a heat source, the smoke temperature is higher than that of the lip-end acetate fiber filter section, and the section is more suitable for volatilization and release of flavoring substances, so that the section has a good application prospect in flavoring the hollow filter stick for the support section.

As for the existing hollow filter stick processing technology, the available flavoring modes are few, and the existing hollow filter stick processing technology mainly comprises the following steps: 1. adding soluble essence into a plasticizer to perfume; 2. directly soaking the molded hollow filter stick in an aroma-enhancing substance to adsorb the aroma-enhancing substance; 3. and additionally coating or spraying an aroma-enhancing substance on the inner surface of the hollow cavity of the molded hollow filter stick. The first of the above methods has the disadvantages that: 1. only the flavor which is compatible with the triacetin can be selected, and the selection range of the essence flavor is narrow. 2. The perfumed triacetin circulates throughout the system, resulting in a cumbersome change of the perfuming formulation and a need for thorough cleaning of the entire plasticizer application system. In the second method and the third method, an additional flavoring step is required after the hollow filter stick is formed, so that the steps are complicated and the cost is increased.

In summary, how to perfume a hollow filter stick more simply and effectively is a problem that needs to be solved by people.

The present invention has been made to solve the above problems.
