Description

Solid gel cigarette rod, preparation method thereof and cigarette comprising solid gel cigarette rod

Technical Field

The invention belongs to the technical field of heating non-combustible cigarettes, and particularly relates to a solid gel cigarette rod, a preparation method of the solid gel cigarette rod and a cigarette comprising the solid gel cigarette rod.

Background

With the improvement of living standard, people pay more and more attention to their health problems, and in recent years, the attention on the health problems of smoking is high. In order to meet the changing consumption requirements of various large enterprises at home and abroad, various completely hollow tobacco products for replacing the traditional cigarettes are developed in a dispute. Among these growing fully hollow tobacco products, electronic cigarettes and heat-not-combusted cigarettes are superior.

The electronic cigarette serving as an electronic product is expanded and applied in the tobacco industry, and has the advantages that the smoking variability is strong, the smoke smoking taste can be randomly regulated and controlled by adjusting components of tobacco tar, but the taste, particularly the heat sensation, of the smoke is generated mainly through an electronic atomizer, and is still different from the traditional cigarette which generates smoke through heating, so that the acceptance of old smokers is poor.

The heating non-combustion cigarette is characterized in that the smoking section of the heating cigarette generates smoke, the acceptance of the smoke taste is good, the smoking section of the existing heating non-combustion cigarette is a reconstituted tobacco sheet filled in an unordered manner, and the cigarette has the problem of insufficient smoke in the smoking process. The insufficient amount of flue gas is mainly due to the following reasons: (1) the reconstituted tobacco lamina used as the smoking segment requires a certain processing strength during the filling process, and also results in a small amount of added flavors and smoke agents; (2) the reconstituted tobacco sheets added with the spices and the smoke agents also need to be subjected to multiple high-temperature treatment procedures, so that the added spices and the smoke agents are seriously volatilized; (3) because the reconstituted tobacco sheets are closely arranged in the smoking section, smoke generated at the front end of the smoking section far away from the filter section can be greatly intercepted at the rear end.

In addition, because the central heating type heating non-combustible cigarette needs to adopt a mode of orderly arranging tobacco shreds in order to meet the requirement of inserting a central heating rod, the normal cigarette heated in the circumferential direction cannot be used on a smoking set heated in the center; the cigarette is not burnt by heating in the circumferential direction, and the burnt flavor of the cigarette paper in the smoke is prominent because the cigarette is directly heated on the cigarette paper.

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

The invention fills the smoking bar formed by the gel surrounded by the outer wall into the smoking section of the heating non-combustion cigarette for the first time. The solid gel smoking rod is not a reconstituted tobacco sheet, so that the adding amount of the smoking agent and the essence perfume in the smoking section is not limited, and the total amount of the smoking agent and the essence perfume added in the smoking section is 5-7 times of that in the reconstituted tobacco sheet under the same weight, so that the problem of insufficient adding amount of the smoking agent and the essence perfume caused by the limitation of processing strength in the reconstituted tobacco sheet can be perfectly solved. Meanwhile, the solid gel smoking rod prepared by the invention can be directly used for manufacturing cigarettes without multiple high-temperature treatment processes, so that the problems that the added spices and smoking agents are seriously volatilized and the loss of volatile components is little are avoided.

2. The preparation method of the solid gel smoking rod adopts a melting and curing method or a compression molding method, so that the loss in the manufacturing process is low, and the preparation method is simple. After heating, the gel core and at least part of the beeswax outer wall are melted and vaporized to generate smoke, the central airflow channel is smooth, and the smoke generation section has no substances for obviously intercepting the smoke. Therefore, the smoke amount is larger than that of the reconstituted tobacco sheet smoking section. The beeswax outer wall also provides a certain fragrance atmosphere.

3. When the cigarette containing the solid gel cigarette rod is sucked, air serving as carrier gas enters from the rear end of atomization, namely the rear end of the cigarette rod, and does not pass through the heating process of the front section, so that the cooling effect of external air on smoke is better.

4. The smoke agent and the essence and spice in the solid gel smoke rod exist in a gel state, and the smoke agent and the essence and spice are not added on the prepared reconstituted tobacco sheet in the prior art, so that the perfuming process is simpler and more uniform, the difficulty can be greatly reduced, and the design cost can be reduced. And the volatilization waste in the process of adding the smoke agent and the essence perfume on the reconstituted tobacco sheet is avoided to the maximum extent.

5. The cigarette containing the solid gel smoking rod can be sucked by adopting two heating modes of center and circumference, and is not limited by smoking tools.

6. Compared with the heating non-combustion cigarette in the prior art, the cigarette rod and the cigarette comprising the same have the advantages that the smoke volume is remarkably increased, the satisfaction is improved, the burning sensation of the smoke is remarkably reduced, the aroma volume is remarkably increased, and no foreign gas is generated no matter the cigarette rod is used for central heating or circumferential heating of a smoking set.
