Description

The present invention belongs to the technical field of non-combustion heat-not-burn tobacco, and particularly relates to a solid gel smoking rod, a method for producing the solid gel smoking rod, and a cigarette containing the same.

As living standards have improved, people have become more and more concerned about their own health, and in recent years there has been a great deal of interest in the health problems of smoking. Major domestic and foreign companies are actively developing completely hollow tobacco products to replace conventional cigarettes in order to meet diverse consumer needs. Among these increasing total hollow tobacco products, electronic cigarettes and non-combustion heat-not-burn tobacco are the mainstream.

Electronic cigarettes have the advantage of being highly variable in flavor and taste, and the flavor of smoke can be arbitrarily adjusted by adjusting the composition of the liquid, as an expanded use of electronic products in the tobacco industry. Since it is mainly produced by an electronic atomizer, its mouthfeel, especially its temperature, is still somewhat different from conventional cigarettes that generate smoke when heated, making it difficult for cigarette smokers to accept.

Non-combustion heat-not-burn tobacco heats the smoke emitting part of the cigarette to generate smoke, and the degree of acceptance of the generated smoke is high. Currently, the smoke emitting part of a non-combustion heated cigarette on the market is a randomly filled reconstructed cigarette sheet, and there is a problem that the amount of smoke is insufficient when sucking the cigarette. The main causes of insufficient smoke volume are (1) the reconstructed tobacco sheet used as a smoke emitting part requires a predetermined processing strength at the time of filling, so that the fragrance and smoke emitted to the reconstructed tobacco sheet are added. The amount of the agent is reduced; (2) The reconstituted tobacco sheet to which the fragrance and the fuming agent are added needs to undergo multiple high temperature treatment steps, so that the added fragrance and the fuming agent volatilize more; (3) Since the reconstructed tobacco sheet is densely arranged in the smoke emitting portion, a large amount of smoke generated at the front end of the smoke emitting portion far from the filter portion is blocked at the rear end.

Also, centrally heated tobacco requires regular arrangement of tobacco nicks to satisfy the insertion of a centrally heated rod, whereas normal circumferentially heated tobacco is used for centrally heated smoking equipment. Since the circumferential heating type tobacco directly heats the cigarette wrapping paper, the burning odor of the paper in the smoke becomes conspicuous.

The present invention is submitted in order to solve the above problems.

The beneficial effects of the present invention are as follows.
1. In the conventional non-combustion heat-not-burn tobacco, the smoke emitting part is generally filled with a reconstructed tobacco sheet. The present invention is the first to fill the smoking part of a non-combustion heated cigarette with a smoking rod formed by surrounding the gel with this outer wall. Since the solid gel smoke stick is not a reconstructed tobacco sheet, the amount of the smoke agent and the fragrance added to the smoke unit is not limited, and the smoke agent and the fragrance added to the smoke unit of the present invention are the same weight. Since the total amount of the reconstructed tobacco sheet is 5 to 7 times that of the reconstructed tobacco sheet and the reconstructed tobacco sheet is limited to the processing strength, the problem that the amount of the fuming agent and the fragrance added is insufficient can be completely solved. .. The solid gel smoke stick produced in the present invention can be used directly in the production of tobacco and does not need to undergo a plurality of high temperature treatment steps, so that it is possible to avoid a large amount of volatility of the added fragrance and smoke agent. However, there is little loss of volatile components.
2. As a method for producing a solid gel smoke rod according to the present invention, a melt solidification method or a press molding method is adopted, there is little loss during production, and the production method is simple. After heating, the core of the gel and at least part of the outer wall of the beeswax melt and vaporize to produce smoke, the central airflow passage is smooth, and there is little blocking of smoke in the smoke emitting part. Therefore, the amount of smoke is larger than that of the smoke emitting portion of the reconstructed tobacco sheet. The outer wall of beeswax also provides a given flavor.
3. The cigarette containing the solid gel smoke stick of the present invention is dependent on the outside air because air as a carrier gas enters from the rear end of atomization, that is, the rear end of the smoke stick at the time of suction and does not go through the previous heating process. Excellent cooling effect on smoke.
4. The fuming agent and fragrance in the solid gel smoking rod according to the present invention exist in the form of gel, and the fuming agent and fragrance are not added to the reconstructed tobacco sheet manufactured in the prior art, and the fragrance process is performed. It is simple and uniform, greatly reducing the difficulty and reducing the design cost. Further, it is possible to minimize waste due to volatilization when a fuming agent and a fragrance are added to the reconstructed tobacco sheet.
5. The cigarette containing the solid gel smoke stick of the present invention is not limited to smoking equipment, and can be sucked by both the central heating type and the circumferential heating type.
6. The smoke stick of the present invention and the cigarette containing the smoke stick may be used for the central heating type smoking device or the circumferential heating type smoking device as compared with the conventional non-combustion heating type cigarette. , The amount of smoke is significantly increased, the feeling of satisfaction is increased, the burning sensation of smoke is significantly reduced, the amount of aroma is significantly increased, and there is no generation of mixed odor.
