According to the preparation method of the heating cigarette cartridge, tobacco powder, an adhesive and a wetting agent are made into tobacco particles through the steps of granulating, screening and drying, the tobacco particles are packaged in the cartridge instead of the tobacco particles in a traditional sheet method, the volume of the tobacco particles is controlled to be 50-80% of the volume in a shell, the packaging is sparse, the porosity of the cartridge is high, after a heating needle is inserted during smoking, the tobacco particles are not prone to falling off and stick to the needle, the cartridge can be directly pulled out, and the product is fast and convenient to use. And the prepared smoke cartridge has small suction resistance and sufficient smoke release, the production process provided by the application is simple, only the existing mature equipment (such as a wet granulator and a rounding machine) needs to be used, and the equipment is simpler than that of a slice method.

In this application, the volume of the tobacco particles in the housing means that the total volume of the individual tobacco particles multiplied by the number of added tobacco particles is the volume of the housing, and the voids between the tobacco particles are not counted within the volume of the tobacco particles. The volume of the tobacco particles is 50-80%, preferably 60-80% of the volume in the housing.

The shell used in the application is made of cigarette paper, and the interior of the shell is sealed after being filled with tobacco particles, so that an opening does not need to be reserved. The cartridge may be made in cylindrical, ellipsoidal or other shapes.

The roller pressing method prepared in step (1) to step (4) of embodiment 1 of patent CN201711312963.5 is adopted to heat the non-combustible embossed reconstituted tobacco shreds to be rolled into cigarette bullets.

Evaluation of

1. Needle sticking condition and sensory evaluation

The suction of example 1, example 2, example 3, and comparative example with a MOK device, the sticking and sensory evaluation are shown in Table 1.

TABLE 1 needle sticking and sensory evaluation

Group of	Needle sticking condition	Evaluation of mouthfeel
			Example 1	The needle is not stuck and can be easily taken out.	High smoke quantity, rich fragrance and good sense effect
Example 2	The needle is not stuck and can be easily taken out.	High smoke quantity, rich fragrance and good sense effect
			Example 3	The needle is not stuck and can be easily taken out.	High smoke quantity, rich fragrance and good sense effect
Comparative example	The tobacco shreds are fallen off due to adhesion on the needles.	Small amount of smoke, flat fragrance and poor sensory effect

As can be seen from table 1, after the cartridge provided by the present application is smoked, the tobacco particles do not adhere to the heating needle because the filler in the cartridge is relatively loose; in the conventional tobacco shred cartridge, the tobacco shreds are tightly attached to the heating needle, and after the tobacco shreds are sucked, the tobacco shreds are adhered to the heating needle.

In addition, the smoke amount of the examples 1,2 and 3 is larger than that of the comparative example, the fragrance is richer, and the sensory effect is good.

2. Release Effect

To examine the release effect of the cartridges, the heated cigarettes were smoked using a heated cigarette smoking machine during the test, and 1, 2-propanediol, glycerol and nicotine were tested according to the method of YQ-EL/T2-2017, with the results shown in table 2.

TABLE 2 Release Effect

Group of	Fragrance ingredient	Nicotine	Glycerol	Propylene glycol
					Example 1	78.6％	25.3％	22.0％	30.5％
Example 2	79.2％	29.1％	21.3％	45.1％
					Example 3	77.9％	22.3％	20.1％	42.3％
Comparative example	72.1％	19.1％	17.5％	30.5％

As can be seen from table 2, the use of the granulated tobacco pellets resulted in greater porosity and more complete heating, and more release of flavor components, nicotine, glycerin and propylene glycol.

3. Sustained release

The release study was performed on the monkshood cooling capsules prepared in example 1, and untreated mint flavor was used as a control. The release profile is shown in figure 1.

The test of the release curve refers to the determination method in section 3.4.1 of Master thesis "preparation of cyclodextrin sustained-release essence and research of sustained and controlled release mechanism". The method comprises the following steps: 3 parts of small bottles filled with the attached aroma cooling capsules are prepared and placed in a constant temperature drying oven at the temperature of 25 ℃ for 0, 1,2, 3, 4 and 5 days. Dissolving the capsule in 4g n-hexane at a fixed time every day, ultrasonically extracting the residual perfume in the capsule, and centrifuging to obtain supernatant. The qualitative and quantitative research is carried out on the essence extracted from the monkshood cooling capsule by using a 7890A-5975C gas chromatography-mass spectrometry combined technology, the test is repeated for three times, and the average value is taken. And (4) carrying out comparative analysis on the aroma components of the essence by using mass spectrograms provided by an NIST database and a Wiley7n.L database. In the same way, the release of mint flavor was measured.

As can be seen from fig. 1, the mint flavor was almost released to 90% of the total amount after 24 hours, showing a release characteristic, which is not advantageous for long-term storage of the mint flavor. However, the accumulative release rate of the heat-sensitive slow-release essence and spice microcapsule after 120 hours is only 39.7 percent, and the result shows that the slow-release cooling material well protects the mint spice from the influence of the external environment and has better slow-release performance.

4. Cooling effect

The simulated smoking is carried out according to a cigarette smoking model specified by the national standard YC/T29, and the temperature of the central position of the middle section of the cigarette filter stick is detected when the cigarette heated by the heating non-combustion cooling section of the invention is smoked by using an MOK heater and a K-type thermocouple temperature detector. The results are shown in FIG. 2.

As can be seen from FIG. 2, the mouth-to-mouth smoking temperature in the comparative example is higher than that in the example, and the result shows that the particle type smoke bomb provided by the application can effectively reduce the smoke temperature and improve the smoking feeling. The cigarette cartridge heated in example 2 has the best cooling effect, and can reduce the temperature of the smoke to below 40 ℃ on average.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
