Description

Solid gel smoke generating stick, manufacturing method thereof, and tobacco comprising same

The present invention belongs to the field of non-combustible heat cigarette technology, and more particularly, to a solid gel smoke-generating stick, a method for manufacturing the solid gel smoke-generating stick, and a cigarette comprising the same.

With the improvement of living standards, people are paying more and more attention to their health problems, and recently, the attention to smoking health problems is very high. In order to meet the changing consumer demand, large domestic and foreign companies have been scrambling to develop a variety of completely hollow tobacco products to replace conventional cigarettes. Among the completely hollow tobacco products that are continuously growing, e-cigarettes and heated non-combustible cigarettes are excellent among them.

E-cigarettes are an expansive application in the tobacco industry for electronic products, and their advantage lies in their strong variability in odor absorption, allowing arbitrary adjustment and control of the inhaled taste of tobacco smoke through tobacco components. It is mainly generated through an electronic atomizer, and there is still a certain difference from the conventional cigarette, which generates cigarette smoke by heating its taste, in particular, a sense of heat, so the acceptance of smokers is relatively low.

In the heated non-combustible cigarette, the smoke generating section that heats the cigarette generates cigarette smoke, so the cigarette smoke generated has a relatively high taste acceptance. As a remanufactured tobacco leaf sheet, tobacco has a problem of lack of a certain amount of smoke in the inhalation process. However, the lack of smoke is mainly because (1) the remanufactured tobacco leaf sheet in the smoke generating section needs to have a certain processing strength during the filling process, so the amount of fragrance and smoke generator added to the upper part is reduced. ; (2) the remanufactured tobacco leaf sheet after adding the flavoring agent and the smoke generator must go through several high-temperature treatment processes, so that the flavor and the smoke generator are severely volatilized; (3) Since the remanufactured tobacco leaf sheet is closely distributed during the smoke generating section, the cigarette smoke generated at the front end of the smoke generating section far from the filter section is blocked at the rear end.

In addition, the steam-heated non-combustible cigarette must use a method of arranging cut tobacco in an orderly manner in order to satisfy the demand for insertion of the central heating stick, but the normal circumferential heat cigarette can be used in a central heating smoking tool. cannot; The heating non-combustible cigarette of circumferential heating is also directly heated on the cigarette paper, so that the burning smell of paper from the cigarette smoke can be clearly felt.

The present invention was created to solve the above problems.

The above technical solutions can be freely combined under the premise that there is no contradiction.

The present invention can achieve the following technical effects.

1. Among conventional heated non-combustible cigarettes, the smoke generating section is usually filled with remanufactured tobacco leaf sheets. The present invention fills the smoke generating stick formed by wrapping the outer wall with gel in this way for the first time in the smoke generating section of the heated non-combustible cigarette. Since the solid gel smoke generating stick is not a remanufactured tobacco leaf sheet, the amount of smoke generating agent and essence fragrance input in the smoke generating section is not limited, and the smoke generating agent and essence fragrance added to the smoke generating section of the present invention under equal weight The total amount of the tobacco leaf sheet is 5 to 7 times that of the remanufactured tobacco leaf sheet, and it can perfectly solve the problem of insufficient addition amount of the smoke generator and essence fragrance generated by the limitation of the processing strength among the remanufactured tobacco leaf sheets. At the same time, the solid gel smoke generating stick manufactured by the present invention can be directly used in the manufacture of cigarettes, and there is no need to go through several high-temperature treatment processes again, so that the added flavor and smoke generator avoid serious volatilization of volatile components. The loss is small.

2. The manufacturing method of the solid gel smoke generating stick according to the present invention uses a melting-hardening method or a press molding method, consumption is low during the manufacturing process, and the manufacturing method is simple. After heating, the gel core part and at least a part of the wax outer wall are melted and vaporized to generate cigarette smoke, the central airflow passage is not blocked, and the cigarette smoke material is not clearly blocked in the smoke generating section. Therefore, compared to the smoke generating section of the remanufactured tobacco leaf sheet, the amount of tobacco smoke is greater. The wax façade also provides a uniformly fragrant atmosphere.

3. The cigarette containing the solid gel smoke generating stick according to the present invention enters from the rear end of atomization, that is, the rear end of the smoke generating stick, as air of the carrier gas when inhaled, and does not go through the heating process of the previous section. , outside air has a better cooling effect on cigarette smoke.

4. The smoke generator and essence fragrance in the solid gel smoke generating stick according to the present invention exist in the form of a gel, and the smoke generator and essence fragrance are externally applied to the top of the remanufactured tobacco leaf sheet prepared in the prior art. Rather than adding, the process of adding fragrance is simpler and more uniform, greatly reducing the difficulty and reducing the design cost. In addition, it is possible to avoid volatilization and waste generated in the process of externally adding a smoke generator and an essence fragrance to the remanufactured tobacco leaf sheet.

5. Cigarettes including the solid gel smoke generating stick according to the present invention can be inhaled using these two heating methods in the center and circumferential direction, so that there is no restriction on smoking tools.

6. The smoke-generating stick according to the present invention and a cigarette including the smoke-generating stick, regardless of whether used for central heating smoking tools or circumferential smoking tools, in comparison with the conventional non-heating non-combustible cigarette cigarettes And, the amount of smoke is significantly increased, satisfaction is increased, burning feeling of smoke is clearly lowered, the amount of fragrance is clearly increased, and bad smell is not generated.
