Description

TECHNICAL FIELD The present invention relates to the field of novel tobacco products, and more particularly to a heated non-combustible tobacco matrix capable of preventing tobacco shreds from falling and its application.

At present, the research and development of heated non-combustible cigarettes has become the focus of research in the tobacco industry. The tobacco or tobacco material can be heated to a degree that releases taste without burning the tobacco or tobacco material. Normally, conventional cigarettes have a smoking temperature as high as 900 ° C or higher, and the leaf tobacco or tobacco material undergoes reactions such as combustion, thermal decomposition, and thermosynthesis under high temperature conditions to generate many potentially harmful substances (HPHCs). Heated non-combustible cigarettes, on the other hand, have smoking temperatures below 400°C, which can reduce the generation of HPHCs during the combustion process. Heated non-combustible cigarettes typically combine a tobacco matrix with a heating device and use heat from the heating device to heat the tobacco matrix components to generate a smoking aerosol. When using both in combination, the tobacco matrix is inserted into the heating chamber of the heating device, and after the tobacco matrix is heated and inhaled, it is necessary to separate the tobacco matrix and the heating device. Chips can fall off and remain on the heater, which is disadvantageous for cleaning and subsequent use of the heater, as well as adversely affecting environmental health. At present, the conventional cigarette ash-prevention means is to coat the outside of the cigarette paper with a layer of metal mesh. Even if the tobacco paper is covered with a mesh, it is not possible to prevent the tobacco pieces from falling off when the heating device is inserted into or removed from the tobacco matrix, and the metal mesh does not damage the tobacco matrix or the heating device due to friction. give. In order to avoid the tobacco shreds from falling when inserting and removing the tobacco matrix, patent CN107205494A discloses a patented technology on an extractor that prevents the tobacco from falling into the heating chamber, but extracts after each use. The operation is complicated because it is necessary to operate the device to remove the cut tobacco, and the remaining cut tobacco that has fallen into the extractor must be cleaned. It is expected in the art that improvements to the tobacco matrix itself will solve the problem of tobacco shreds falling off when the tobacco matrix is inserted and removed.

SUMMARY OF THE INVENTION The object of the present invention is to provide a heated non-burning tobacco matrix that can prevent tobacco cuts from falling, in order to solve the drawback of the prior art that tobacco cuts fall off.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a heated non-combustible cigarette comprising a heated non-combustible tobacco matrix that is capable of preventing cut tobacco from falling off.

Another object of the present invention is to provide a method of using a heated non-combustible cigarette.

The above objects of the present invention are achieved by the following technical solutions.

A heated non-burning tobacco matrix capable of preventing shredded tobacco from dropping, which is produced by winding puffed shredded tobacco, composite shredded tobacco and/or tobacco sheets in a random mixture, and the density of the tobacco matrix is 0.25-0. 65 g/cm ³ .

The puffed cut tobacco is added to the tobacco matrix as a filler and randomly mixed with other components of the tobacco to increase the degree of random entanglement of the puffed cut tobacco matrix and improve the stability of the entire tobacco matrix during insertion and removal of the heater. maintains and plays a good supporting effect on the tobacco matrix, effectively reducing the tobacco chipping rate, which is the falling of tobacco chips when inserting and removing. In addition, the addition of puffed tobacco allows the filling rate of the entire tobacco matrix to be adjusted, ensuring the ventilation of the air channels, which is advantageous for the distribution of the airgel produced by heating and the transfer of heat.

The density or fill value is indicated as the compactness of the shredded tobacco, and too much density increases the mass of the tobacco matrix and makes it too dense, leading to cigarette "tip cracks" and obstruction of airflow when smoking, If the density is too small, the interaction force between the components is insufficient, and the cut tobacco tends to fall off.

In order to obtain a suitable density, the internal structure should be stable when the heating element is inserted into the shredded tobacco, and the extrusion by the heating element should make contact with the heating element over as large an area as possible to improve the heat transfer efficiency. Also, it should be taken into account that the tobacco matrix, upon extrusion by the heating element, allows for suitable airflow passages and ventilation so that the tobacco structure can remain in a stable form after heating and baking.

Preferably, the tobacco matrix has a moisture content of 5.0 to 12.5% by weight.

In particular tobacco matrices, the tobacco matrix has a density of 0.25 g/cm ³ , 10.5% moisture by weight, a density of 0.45 g/cm ³ , 11.5% moisture by weight, or a cigarette density of 0.65 g/cm ^3. The water content may be 9.5% by mass.

The moisture content of cut tobacco has a significant impact on both the organoleptic characteristics, the brittleness and elasticity of the cut tobacco, and also affects its processing performance, with the moisture content of some components being 11.5-12.5% higher than that of conventional cigarettes. Controlled to a 5% lower level.

Preferably, the moisture content of at least one of the three components of the tobacco matrix is controlled at 5.0-11.0%, thereby adjusting the moisture content of the overall tobacco matrix while improving the physical properties of the overall tobacco matrix. can be adjusted, facilitating machining. Increases brittleness and ensures stability of disordered tobacco structure while not affecting moisture or processing performance.

Preferably, the weight of the puffed tobacco is between 5% and 40% of the total weight of the tobacco matrix.

Preferably, the weight of the puffed tobacco is between 15% and 30% of the total weight of the tobacco matrix.

The puffed tobacco leaf cuts lose a lot of flavor components during the manufacturing process, so the flavor is not rich. In this case, it has been found that the smoking feeling of the tobacco matrix can be sufficiently ensured, and the dropping of the tobacco shreds can be effectively prevented.

Preferably, the puffed tobacco has a fill value of 4.5-7.5 cm ³ /g and a whole cut rate of 70-90%. For example, the filling value is 7.12 cm ³ /g, 4.88 cm ³ /g, 6.21 cm ³ /g or 6.07 cm ³ /g and the whole cut rate is 70%, 75% , 80%, 83%, 85% or 87%.

The filling value of puffed tobacco is an important indicator of the puffing effect, the high filling rate can directly improve the filling rate of the whole tobacco matrix, and the whole cut rate is the main indicator of puffed cut tobacco structure. It is possible to effectively secure the function of supporting the puffed cut tobacco to the tobacco matrix. Effectively reduce the rate of tick drop.

Preferably, said puffed tobacco leaf cuts have a fill value of 6.5-7.5 cm ³ /g and a whole cut rate of 83-90%.

Preferably, the size of said puffed tobacco is ≧1.0 mm. If the puffed tobacco is less than 1.0 mm in size, it becomes chopped tobacco, and the chopped tobacco cannot effectively support the tobacco matrix, and also impairs the ventilation of the air channels throughout the tobacco matrix, increasing smoking resistance. do.

The length of the cut tobacco affects the degree of bending and whether it can be processed smoothly. "," and "partial swelling of the tobacco body" occur, and given a suitable length, contribute significantly to the processing performance of the tobacco matrix. Such suitable length components may be any one or two of composite shredded tobacco, tobacco sheets. Due to the large difference in the manufacturing method and physical properties of each component, a component with high elasticity and too long length is not suitable for the heat non-combustible tobacco matrix, and other lengths may be selected. Also consider the physical index of

For each component of tobacco, length here is also the size at its largest or widest point.

Preferably, said puffed cut tobacco is puffed tobacco leaf cuts and/or puffed cut midribs.

Preferably, said puffed tobacco is puffed tobacco. The puffed tobacco leaves are superior to the puffed midribs in terms of flavor and smoking quality, the whole cut rate and puffed size are also greater than the puffed midribs, and the space filling rate and tar and harm reduction. is superior to common cut tobacco, and thus can further improve the smoking sensory performance of the tobacco matrix, and therefore puffed tobacco leaf cuts are preferred.

Preferably, the weight of said composite shredded tobacco is 0-95% of the total weight of the tobacco matrix.

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

Preferably, the tobacco sheet has a thickness of 0.1-0.3 mm, a length of 2-30 mm and a width of 1-2 mm.

Tobacco sheets can be produced by a dry method, a roll press method, or a papermaking method. Of these, when a tobacco sheet is produced by a papermaking method, a two-step method is used, namely, extracting tobacco raw materials and removing a solid phase. Tobacco sheets are produced by a papermaking method, the liquid phase is concentrated and then applied to the tobacco sheets, and the obtained tobacco sheets are shredded to obtain tobacco sheets. Controlling the length and width of the tobacco sheet is beneficial to entanglement with puffed tobacco, further improving stiffness and spatial stability, increasing airflow passages, and reducing the risk of falling tobacco. rate can be reduced.

Preferably, the composite cut tobacco and/or the tobacco sheet and/or the puffed cut tobacco carry a tobacco extract, an atomizing agent and a flavor component.
