Description

A heat-not-burn tobacco substrate for preventing shredded tobacco from falling and its application

technical field

The invention relates to the field of novel tobacco products, in particular to a heat-not-burn tobacco substrate capable of preventing shredded tobacco from falling and an application thereof.

Background technique

The research and development of heat-not-burn cigarette products is currently a research hotspot in the tobacco industry. Unlike traditional cigarettes, heat-not-burn cigarettes designed with the idea of "heat-not-burn" can heat the tobacco leaves or tobacco materials just enough to release the taste. degree without igniting the tobacco leaf or tobacco material. Under normal circumstances, the smoking temperature of traditional cigarettes is as high as 900°C. Tobacco leaves or tobacco materials produce many potentially harmful substances (HPHCs) due to combustion, pyrolysis, thermal synthesis and other reactions under high temperature conditions, while the smoking temperature of heat-not-burn cigarettes Below 400°C, the generation of HPHCs during combustion can be reduced. Heat-not-burn cigarettes mainly cooperate with the tobacco base and the heating device, and use the heat of the heating device to heat the components of the tobacco base to generate aerosol for smoking. When the two are used together, the tobacco base body needs to be inserted into the heating chamber of the heating device, and the tobacco base body needs to be separated from the heating device after the tobacco base body is heated and sucked. In the heater, it is not conducive to the cleaning and subsequent use of the heater, and also affects the sanitation of the environment. At present, the method to prevent the ash falling of traditional cigarettes is to wrap a layer of metal mesh cover on the outside of the cigarette paper, but this operation is not suitable for low-temperature non-burning cigarettes. Pulling out the shredded tobacco caused by the heating device has a preventive effect, and the metal mesh cover will also cause friction damage between the tobacco substrate and the heating device. In order to prevent the tobacco matrix from falling when plugging and unplugging, patent CN107205494A discloses the patented technology of the extractor to prevent the tobacco from falling into the heating chamber. Clean up any shreds that fall into the extractor. What is expected in the field is to solve the problem of shredded tobacco falling during insertion and extraction through the improvement of the tobacco matrix itself.

Contents of the invention

The invention aims at overcoming the deficiency of shredded tobacco falling in the prior art, and provides a heat-not-burn tobacco base body which prevents shredded tobacco from falling.

The object of the present invention is to provide a heat-not-burn cigarette, which contains a heat-not-burn tobacco matrix that prevents shredded tobacco from falling off.

Another object of the present invention is to provide a method for using a heat-not-burn cigarette.

The above object of the present invention is achieved through the following technical solutions:

A heat-not-burn tobacco substrate that prevents shredded tobacco from falling. The tobacco substrate is rolled by random mixing of expanded filaments, formulated leaf group filaments, and/or tobacco flakes. The density of the tobacco substrate is 0.25-0.65 g/cm ³ .

The expanded silk is added to the tobacco matrix as a filler, and the disordered winding degree of the expanded tobacco matrix is increased through the disordered mixing of the expanded silk and other components of the tobacco, so that the entire tobacco matrix can maintain the overall integrity during the insertion and removal of the heater. Stability, it plays a very good supporting role on the tobacco matrix, effectively reducing the adjustment rate of tobacco falling off when plugging and unplugging. In addition, the addition of expanded filaments can also adjust the filling rate of the entire tobacco matrix, ensure the smoothness of the air passage, and facilitate the circulation of the airgel formed by heating and the transfer of heat.

Density or filling value is directly expressed as the tightness of shredded tobacco. If the density is too high, the mass of the tobacco matrix will increase, and if it is too dense, it is easy to cause problems such as "head burst" of cigarettes and unsmooth air flow and large resistance during smoking. If the density is too small, each group The interaction force between the points is not enough, and the wire is easy to fall off.

The appropriate density should also consider that when the heating element is inserted into the shredded tobacco, the internal structure is stable, and the extrusion of the heating element ensures as large a contact with the heating element as possible to improve the heat transfer efficiency. At the same time, the extrusion of the heating element makes the tobacco matrix still It can provide proper air flow path and ventilation, and the tobacco structure can maintain a stable shape after heat curing.

Preferably, the moisture mass percentage of the tobacco matrix is 5.0-12.5%.

In a specific tobacco matrix, the density of the tobacco matrix can be 0.25g/cm ³ , the mass percentage of moisture is 10.5%, the density can be 0.45g/cm ³ , the mass percentage of moisture is 11.5% or the density of the matrix can be 0.65g/cm ³ , the water mass percentage is 9.5%.

The moisture of shredded tobacco has an important influence on the sensory characteristics, brittleness and elasticity of shredded tobacco, and more importantly, its processing performance, by controlling the moisture of a certain component at a level relatively lower than that of traditional cigarettes by 11.5-12.5%.

Preferably, the moisture of at least one of the three components of the tobacco matrix is controlled at 5.0-11.0%. On the one hand, it is to regulate the moisture of the tobacco matrix as a whole, and it can also adjust the overall physical properties of the tobacco matrix, which is convenient for machining. It will not significantly affect the moisture content and processing performance, but also increase the brittleness and ensure the stability of the disordered tobacco structure.

Preferably, the mass of the expanded filaments is 5% to 40% of the total mass of the tobacco matrix.

Preferably, the mass of the expanded filaments is 15% to 30% of the total mass of the tobacco matrix.

Due to the large loss of aroma components in the preparation process of expanded shredded tobacco, the inventor found through continuous exploration that when the amount of expanded shredded tobacco is 15% to 30%, it can not only fully ensure the smoking sensation of the tobacco matrix, but also improve the smoking quality of the tobacco matrix. To achieve the effect of preventing the shredded tobacco from falling.

Preferably, the filling value of the expanded yarn is 4.5-7.5 cm ³ /g, and the whole yarn ratio is 70-90%. For example, the filling value can be 7.12cm ³ /g, 4.88cm ³ /g, 6.21cm ³ /g or 6.07cm ³ /g; the whole filament rate can be 70%, 75%, 80%, 83%, 85% or 87 %.

The filling value of the expanded filament is an important indicator of the expansion effect. A high filling rate can directly improve the overall filling rate of the tobacco matrix; the whole filament ratio is the main indicator of the expanded filament structure, and the solid filament ratio can effectively ensure the support stiffness of the expanded filament to the tobacco substrate The effect of certain shred rate is also conducive to the improvement of the degree of winding between the expanded shredded tobacco and the tobacco sheet, which can well reduce the drop-out rate of shredded tobacco.

Preferably, the filling value of the expanded shredded tobacco is 6.5-7.5 cm ³ /g, and the whole shredded tobacco ratio is 83-90%.

Preferably, the size of the expanded filaments is ≥1.0 mm. Shredded silk whose size is less than 1.0mm is shredded, and shredded shreds not only cannot play a good supporting role on the tobacco matrix, but also affect the smooth flow of the entire tobacco matrix and increase the resistance to suction.

The length of shredded tobacco affects the bending degree and whether the processing is smooth. Too long shredded tobacco may easily cause uneven density of shredded tobacco inside, and appear "short" or "slub smoke". The appropriate length has a great influence on the processing performance of the tobacco matrix. This component with a suitable length can be any one or both of formula leaf group shreds and tobacco flakes. Considering that the manufacturing methods and physical properties of each component are very different, components with high elasticity and too long length are not suitable for use in the heat-not-burn tobacco matrix, and the selection of the length should be combined with other physical indicators.

For various components of tobacco, length here also refers to the largest or widest dimension.

Preferably, the expanded shreds are expanded cut tobacco and/or expanded cut stems.

Preferably, the expanded shreds are expanded shredded tobacco. Expanded shredded tobacco is superior to expanded shredded stems in terms of aroma and smoking quality, and its trim ratio and expansion size are also greater than those of expanded shredded stems. At the same time, it is superior to ordinary shredded tobacco in terms of space filling rate and coke reduction and harm reduction, which can further improve the quality of tobacco. Smoking organoleptic properties of the substrate, therefore expanded cut tobacco is preferred.

Preferably, the mass of the formula leaf group shreds is 0-95% of the total mass of the tobacco base.

Preferably, the mass of the tobacco sheet is 0-95% of the total mass of the tobacco matrix.

Preferably, the size of the tobacco sheet is 0.1-0.3 mm in thickness, 2-30 mm in length, and 1-2 mm in width.

Tobacco sheet can be prepared by dry method, roller pressing method and papermaking method. The papermaking method adopts a two-step method to prepare tobacco sheet. The tobacco raw material is first extracted, and the solid phase is prepared by papermaking method. The liquid phase is concentrated and then coated on the tobacco sheet. Above, the tobacco sheet is prepared by shredding after obtaining the tobacco sheet. Controlling the length and width of the tobacco sheet is conducive to intertwining with the expanded filament, further improving the stiffness and dimensional stability, not only helping to increase the airflow channel, but also reducing the drop-out rate of the shredded tobacco.

Preferably, the tobacco extract, aerosol and aroma components are loaded on the formula leaf group shreds and/or tobacco sheet and/or expanded wire.

The present invention also protects a heat-not-burn cigarette, which comprises the heat-not-burn tobacco matrix. The heat-not-burn cigarette includes a mouth contact segment, a cooling segment and a heat-not-burn tobacco base segment, wherein the heat-not-burn tobacco base segment is the heat-not-burn tobacco base body of the present invention.

The present invention also protects the method for using the above-mentioned heat-not-burn cigarette, which includes the following steps: inserting the heat-not-burn cigarette into a heating element for fixed heating, sucking, and pulling out the heat-not-burn cigarette after turning at least 30 degrees after smoking.

The specific heater includes a heating element and a fixing seat for the heating element, a sleeve, a control element, a casing, and a cigarette insertion port on the casing, a ventilation hole, a power switch, the The sleeve, the heating element and the cigarette insertion port constitute the heating chamber of the tobacco base body. The airflow enters the heater and the cigarette through the vent hole, and the cigarette is inserted into the sleeve through the cigarette insertion port and receives the heat of the heating element. , there is a positioning piece on the sleeve, so that the heat-not-burn tobacco base can receive the heat of the heating element to the maximum extent.

The specific operation is as follows:

(1) Heat-not-burn cigarettes are inserted into the heating cavity through the cigarette insertion port, and are in contact with the positioning member;

(2) Press the power switch key to start heating, so that the heat of the heating element heats the heat-not-burn tobacco substrate for people to smoke;

(3) After smoking, turn at least 30 degrees and pull out the heat-not-burn cigarette.

The root of the shredded tobacco not falling is that the structure is stable and the strength is moderate. Even if the heating rod is inserted, the structure can be guaranteed, and the extrusion effect of the heating rod can keep the shape of the interior from changing significantly after heating.

Compared with the prior art, the present invention has the following beneficial effects:

Comparative example 1

A heat-not-burn tobacco substrate, which is rolled from tobacco sheet, which is the same as that in Example 1, with a thickness of 0.1 mm, a length of 2 mm, and a width of 1 mm. After heating and smoking, the shredded tobacco drop rate was rated as 4, and the draw resistance was 0.935kPa.

Comparative example 2

A heat-not-burn tobacco substrate, which is rolled out after random mixing of tobacco flakes and expanded shredded tobacco. The tobacco flakes are the same as in Example 1, with a thickness of 0.1 mm, a length of 2 mm, and a width of 1 mm. The filling rate of the expanded shredded tobacco is 7.12 cm3/g, the whole filament rate is 83%, and the mass fraction is 5%.
