Temperature-variable controlled-release gel composite material and application thereof in cigarette filter stick

Abstract

The invention provides a temperature-variable controlled-release gel composite material and application thereof in a cigarette filter stick, and belongs to the technical field of preparation of cigarette holders. A preparation method comprises the steps that gel is heated and melted; then the gel is conveyed into an infiltration tank with a heat preservation function; a common aroma-increasing core wire is wound through an unwinding mechanism and then guided to the infiltration tank, the core wire is immersed into the liquid gel, and the concentration of the liquid gel is adjusted so that the thickness of a gel layer attached to the surface of the aroma-increasing core wire can be larger than or equal to the diameter of the aroma-increasing core wire; then cooling and drying are conducted on the infiltrated aroma-increasing core wire, the gel is solidified into a solid which is attached to the surface of the aroma-increasing core wire, and accordingly the temperature-variable controlled-release gel composite material is obtained. According to the composite material prepared from the gel and the prepared filter stick, the forming degree and the aroma locking effect are good, production arrangement of the filter stick is facilitated, obtained products are relatively rich, and quick volatilization of the gel which is simply applied to the filter stick during smoking can be slowed down, so that a whole cigarette has a relatively balanced mouth feel.

Description

technical field [0001] The invention relates to the technical field of cigarette holder manufacture, in particular to a temperature-varying slow-release gel composite material, a manufacturing method and its application in cigarette filter rods. Background technique [0002] With the development of current cigarette technology, the content of thermal volatiles in cigarettes has been greatly reduced, but it has also greatly affected its taste. Therefore, the introduction of flavoring technology has become the only way for the current cigarette industry. By adding Aroma-inducing ingredients to supplement the concentration of smoke without increasing the content of harmful substances. The essence formulated on the basis of scientific research has changed its main ingredients from the aroma-inducing substances contained in natural substances and synthetic tobacco itself, so the effect is relatively strong. It will not produce peculiar smell if it is too large, and it can also be...

Problems solved by technology

[0005] There is also a filter rod flavoring method, that is, adding flavoring gel to the filter rod, taking advantage of the gel's good fragrance retention performance at room temperature, and the characteristics of volatilization and release under the influence of flue gas temperature during smoking, and the adding process is relatively simple , such as "A Composite Gel Fragrance Sustained-Release Granule and Its Preparation Method and Its Application 201610764049.3", the preparation method includes the steps of preparing a raw material mixture solution, preparing a composite gel and adding fragrances, and using polyethylene glycol and β-cyclodextrin, gelatin and other composite gels are used as particles made of materials, which can effectively increase the amount of fragrance added to the granular filter rod, and the uniformity, controllability and stability of the fragrance; and "a linear composite Gel fragrance slow-release filter stick and its preparation method and its use, 201610064101.4", relates to a thread-shaped composite gel fragrance slow-release filter stick, its preparation method and its use, without the need to use traditional cotton thread or synthetic fiber The made incense thread is used as a carrier, and the gel thread made of polyethylene glycol and chitosan carmellose sodium is used to simulate the traditional incense thread, but in this way, when the tow is extruded, the gel It is easy to flow in the radial or axial range of the filter rod, or even emerge from the end of the filter rod, which will eventually affect the shape of the filter rod, reduce the fragrance retention effect and affect the overall appearance of the filter rod; and the filter rod is prepared in this way It can only be produced online, that is, gel application and tow forming must be carried out at the same time, and the resulting product is relatively single, and it is impossible to produce various forms of gel filter rods according to demand; in addition, because the gel is directly combined with the tow , when smoking, the melting and volatilization of the gel are relatively direct and fast, and the flavor is often strong in the early stage of smoking, but the taste is weak in the later stage, resulting in large fluctuations in the taste of the whole cigarette
