Description

Low-Break Heating Non-combustible Cigarette Tobacco

The patent according to the present invention relates to the field of production technology of heated non-combustible cigarette, and more particularly, to a low-blocking heated non-combustible cigarette cigarette.

As consumers place importance on health problems and demand for cigarette product-specialized experiences has increased, the tobacco industry has continuously responded to consumer demand upgrades and has developed a variety of tar-reducing risk-reducing cigarettes. Among them, the heated non-combustible cigarette can provide a healthier inhalation experience while satisfying the consumer's sensory demand for cigarette products, unlike conventional cigarette products, in its cigarette heating method.

Conventional heated non-combustible cigarette tobacco mainly includes a smoking core material section, a support section, a temperature drop section and a filter section, where the support section not only serves as a support for the cigarette, but above all, collects smoke and Coordinate the temperature drop section to lower the smoke temperature. The prior art is an online laser drilling method by forming a ventilation hole by penetrating the tube wall of the support section, the molding paper that rolls the tube wall and the tipping paper, and allowing outside air to enter the inside of the support section and mix with the smoke. Although it increases the weightlessness and lowers the smoke temperature effectively, the temperature lowering effect of the smoke and the mixing effect of the air and the smoke are still not good, for the following two reasons. First, the tube wall of the support section lacks radial bearing capacity, and the tube wall is depressed toward the center of the tube cavity after receiving an external force, so that the airflow passage of smoke and air is closed, and the amount of mist is insufficient; Second, since the contact area between the smoke and the tube wall of the support section is limited, it cannot effectively lower the temperature; Third, the residence time of smoke and air in the support section is short, and the smoke and air directly pass through the support section quickly and enter the temperature drop section, so that sufficient mixing cannot be achieved. Therefore, in order to better implement the temperature drop of the smoke, currently, the temperature drop material in the temperature drop section is mainly improved or the amount of the temperature drop material is directly increased, but many of the temperature drop materials are phase change materials, so take a few sips. After that, the phase transfer material contracts and sinks to close the airflow passage, greatly improving the suction suppression and affecting the suction experience.

In another aspect, the following problems exist when the hole is drilled in the support section of the cigarette using the online laser drilling method. First, the online laser drilling process has relatively high requirements for the material and thickness of the tube wall in the support section. Above all, the material of the tube wall in the support section is It should not be depressed during laser drilling and the tube wall of the support section should not be particularly thick; Second, the online laser drilling process has a very high laser power requirement. If the laser drilling equipment fails to drill the tube wall of the support section, the heated non-combustible cigarette cigarette will be rejected and the smoke temperature will be overheated; Third, the current support section and the supporting section are rolled through the forming paper and tipping paper to form a ventilation hole, and the outside air directly passes through the ventilation hole and enters the support section, In addition to the high speed, the contact area between the incoming air and the smoke is limited and not evenly mixed, so the amount of smoke inhaled into the consumer's mouth is increased, but the smoke concentration is low and the smoke quality is seriously deteriorated because a large amount of air is clearly mixed in the smoke. ; Fourth, all of the conventional online laser drilling methods are configured so that the support section is drilled at a point of 14mm to 15mm or 18mm to 19mm close to the cigarette section so that the ventilation hole is fixed in position.

Therefore, consumers have excellent support for the entire cigarette and the technical measures that take into account the smoke temperature drop and the role of smoke gathering, that is, heating with a suitable smoke temperature, sufficient amount of mist, even mixing with smoke, and excellent smoke quality. They want to develop non-combustible cigarettes.

(1) Select a paper with excellent support performance. When flattened, the width is 50 mm, the thickness is 200 μm, the gram weight is 150 g, and the first air permeable paper is obtained by pressing it into a porous structure, but its air permeability is 5000 CU;

(2) Select one side of the first ventilation paper so that it faces upward, and the upward-facing side is named the front side, and then fold the first ventilation paper sequentially along one side and toward the other side toward the front and back sides of the corrugated paper Obtaining a first venting paper of the shape and aggregating the first venting paper of a wavy shape to obtain a support member 23 having a wavy cross-section, and rolling one side of the wavy-shaped first venting paper toward the other side has a hollow polygonal cross-section To obtain a support member 23 forming the. Here, one end of the folded support member 23 rotates in one direction, and after rotation, the angle twisted in the circumferential direction so that the one end is relative to the other end is obtained. If it is 10°, it is possible to immediately obtain the support member 23 helically extending along the axial direction of the support section 2 .

Here, step (1) is to press the paper with excellent support performance to become a porous structure and form the first ventilated paper so that hot smoke and air are sufficiently mixed inside the support section 2 and no dent problem appears, where , paper that is easily folded and molded with a certain hardness can be used as the paper having excellent support performance in step (1), and in this embodiment, molded paper having a high gram weight is selected and used.

The support member 23 is provided with a fragrance enhancing material layer (231). A mixed solution of ethanol and glycerin is used as a solvent, wherein the glycerin content is higher than 50%. A saturated solution is prepared by adding tobacco extract and tobacco aroma substances in the solvent. By spraying the saturated solution on the first ventilation paper formed by folding the support member 23, that is, the first ventilation paper formed in step (1), the fragrance enhancing material layer 231 on the support member 23. To form a, here, the first venting paper formed by folding the support member 23 sprays 3 mL of the saturated solution per 1 gram.

Here, the material of the tube wall 21 is paper.

The process of manufacturing rolled cigarettes in this embodiment is as follows. First, a window is opened in advance on the paper forming the tube wall 21 through a cutting method, and then the paper is again folded in half and rolled to form a support section 2, so that the ventilation window 25 can be formed, , then the tip paper 6 is pre-drilled to form the ventilation hole 26 . In the roll manufacturing process, the support section (2), the temperature drop section (3) and the filter section (4) are first rolled with the molded paper (5) of the ventilation nonwoven type to form a mouth stick, and again the tip The smoking core material section 1 and the mouth stick are wound with paper 6 to form the cigarette, wherein the ventilation hole 26 and the ventilation window 25 partially overlap.

Here, the temperature drop section 3 is an aggregated polylactic acid net-like film.

Here, the filter section 4 is a cellulose acetate tow.

Here, the smoking core material section 1 is a rod-shaped smoking cigarette wick formed by disorderly filling tobacco containing a smoke agent.

The heated non-combustible cigarette cigarette produced in this example was named cigarette sample 3, and as a result of comparing the tobacco sample 3 of Example 3 and the tobacco sample 2 of Example 2 according to the present invention, both of the support section (2) Only the ventilation structure is different, and when both are used in a non-burnable cigarette smoking device and inhaled, the smoke temperature at which cigarette sample 3 enters the smoker's mouth is 33°C, and the smoke temperature at which cigarette sample 2 enters the smoker's mouth is slightly lower than the temperature. However, according to the points felt by several sensory evaluation personnel after inhaling tobacco sample 2 and tobacco sample 3, when the area of the ventilation hole 24 of tobacco sample 2 and the ventilation window 25 of tobacco sample 3 are the same, tobacco sample 2 smoke generated in the inhalation process had a high air concentration and a large amount of air was clearly mixed in the smoke, but tobacco sample 3 did not feel that air was mixed in the smoke during the inhalation process, and the smoke and air were uniformly mixed, The smoke quality was high.
