Definitions
- the present invention relates to smoking filters.
- Japanese Patent Laying-Open No. 60-11033 proposes an acetate fiber filter for tobacco carrying cyanobacterial spirulina formed in a granular form.
- This publication states that a filter carrying blue-green algae Spirulina was attached to a pipe and smoke was passed through the pipe. According to the report, it was 42.4% for nicotine, 53.2% for tar, and 75.1% for 3,4-benzpyrene.
- Japanese Patent Application Laid-Open No. 62-797766 discloses a filter wound with a sheet-like carrier in which a mixed processed cotton-like body or agaric powder / crude cotton-like body is retained. Luther has been proposed. This publication describes that the removal rates of 3,4-benzbilene by each filter were 62% and 35%, respectively. However, these filters have insufficient performance in removing high boiling components from tobacco smoke.
- a smoking filter having a filter material, the device including a means for heating the filter material or a periphery of the filter material.
- the means for heating the periphery of the filter medium does not directly heat the filter medium, but includes, for example, a smoking article (a cigarette holder, etc.) that indirectly heats the filter medium wound on chip paper from outside. ) including.
- the filter medium is made of heat-resistant fiber. It is preferable that the filter made of heat-resistant fiber has heat resistance that does not change even when the temperature is increased to about 300 ° C.
- the filter medium is a high-filtration filter capable of filtering particles by approximately 100%.
- a high-filtration filter is a filter that removes almost 100% of the particulate components in tobacco smoke and allows almost all vapor components to pass through.
- the fiber diameter of the high-filtration filter ⁇ the airflow resistance may be about the same as that of a normal filter, and the fiber diameter is from submicron to several tens of micron, and the airflow resistance is 200 mmH2 ⁇ or less. .
- the present invention is characterized by filtering by changing the gas-liquid distribution of the smoke by heating, a similar effect may be expected even if the heated smoke is passed through an unheated filter medium. There is. Therefore, after heating the smoke before the filter media and changing the gas-liquid distribution May be passed through a filter medium.
- a high filtration filter may be placed immediately after the combustion cone.
- Ayres registered trademark
- the smoke generation position does not change, it is only necessary to place a high-filtration material immediately after that.
- the spontaneous combustion is slow when combined with low-burning wrapping paper, so the filter material can be arranged with the single wrapping part short enough.
- the heating means used in the smoking filter of the present invention is preferably capable of controlling the temperature in the range of 100 to 200 ° C. Further, the filter temperature may be controlled in two or more steps, such as 200 ° C. and 100 ° C.
- the smoking filter of the present invention may further have a cooling part.
- charcoal, layered phosphate, and other additives may be used in combination as an adsorbent.
- high-boiling components can be selectively filtered by applying heat to the extent that necessary components such as flavor-enhancing components in tobacco smoke evaporate but high-boiling components do not evaporate.
- FIG. 1 is a view showing a state in which a cigarette is attached to a smoking filter according to one embodiment of the present invention.
- FIG. 2 shows the configuration of the automatic smoking experiment.
- Figure 3 shows the relationship between the filter temperature and the outflow of each component.
- Figure 4 shows the relationship between filter temperature and the ratio of nicotine to tar outflow (NZT ratio).
- Figure 5 shows the relationship between the filter temperature and the transmittance of each component.
- FIG. 6 is a diagram showing a state in which another cigarette is attached to the smoking filter according to one embodiment of the present invention.
- FIG. 7 is a diagram showing the relationship between the vapor pressure of each smoke component and the transmittance.
- FIG. 8 is a view showing a state in which zirconium phosphate is added to a smoking filter according to one embodiment of the present invention.
- Figure 9 shows the outflow of nicotine and aromatic amines with and without the addition of zirconium phosphate.
- FIG. 10 is a view showing a state in which the temperature of a smoking filter according to one embodiment of the present invention is controlled in two stages.
- Fig. 11 shows the outflow of nicotine and aromatic amines from smoking fil- ters with temperature control in one and two stages.
- FIG. 1 is a view showing a state in which a cigarette is attached to a smoking filter according to one embodiment of the present invention.
- a smoking filter As shown in Fig. 1, inside a smoking filter 1, a HEPA filter (High Efficiency Particulate Air Filter) as a high-filtration material 2 and a heater 3 provided around the HEPA filter are arranged.
- a cigarette 10 is attached to the tip of the smoking filter 1. During smoking, heater 3 heats high filtration media 2.
- Figure 3 shows the filter temperature, tar (Tar), and nicotine.
- Figure 4 shows the relationship between filter temperature and the ratio of nicotine to tar outflow (NZT ratio). Thousands of grains in tar It contains a child phase component, and the temperature at which each component evaporates varies. For this reason, tar and nicotine have different outflows depending on temperature. As can be seen from Fig. 4, the N / T ratio was highest when the filter temperature was set to 125 ° C, and was about eight times that in the blank case.
- FIG. 5 shows the relationship between the filter temperature and the transmittance of each component.
- This figure shows the relative transmittance of tar (T ar), nicotine (N ic), benzopyrene (BaP), and aromatic amines (A as) assuming that the transmittance in the blank is 1.
- Nicotin hardly permeates at 22 ° C, but reaches about 0.2 at 100 ° C, about 0.5 at 125 ° C, and about 0.8 at 200 ° C.
- the increase of the transmittance with respect to is remarkably seen.
- the temperature is higher than 200, almost all the amount is considered to pass through the HEPA filter, since nicotine was not detected from the HEPA filter heated after the experiment.
- the permeability is considered to be about 0.8 at a value of 200 or more. Even in the case of evening water, ventzpyrene and aromatic amines, even at 300 ° C, the permeation is not enough due to insufficient evaporation and by sticking to piping etc. It is probable that the rate did not become 1. If the filter temperature is set at 125 to 150, almost no benzopyrene or aromatic amines, which are undesirable for smoking, will be transmitted. Without passing through, it is possible to selectively permeate flavor-contributing components having a nicotine boiling point or lower. In addition, when the filter temperature is in the range of 100 to 200 ° C., the effect of selective permeation as described above can be obtained.
- the filter temperature was always kept constant during the period from 1 puff to 6 puffs. It is considered that the same effect can be obtained even if the heating is performed in the above manner.
- the high-filtration media was heated to 200 ° C and puffed by 1 to collect permeated tobacco smoke.
- the collected tobacco smoke was analyzed by GC / MS, and the relationship between the vapor pressure of each vapor component and the transmittance was examined.
- Figure 7 shows the results.
- zirconium phosphate 4 (CPZ-100, manufactured by Daiichi Rare Element Chemical Co., Ltd.), which is a layered phosphate, was sandwiched between two HEPA filters. With the equipment loaded as shown in Fig. 2, the temperature of the high-filtration material was set to 200 ° C, and an automatic smoking experiment was performed.
- Figure 9 shows the outflow of nicotine and aromatic amines when zirconium phosphate was added, compared to the case without zirconium phosphate.
- Figure 9 shows that adding an adsorbent, such as zirconium phosphate, to the HEPA filter overnight can selectively remove aromatic amines with little change in nicotine permeability. It was shown. Further, for example, a method of adding an oxidation catalyst or the like that works effectively at a high temperature to the HEPA file to convert carbon monoxide, which is not preferable for smoking, to carbon dioxide can be considered.
- FIG. 10 shows an embodiment in which two smoking filters having a high filtering material and a heater around the filter are provided.
- the upstream filter temperature was set to a high temperature (200 ° C)
- the downstream filter temperature was set to a low temperature (at 100 ° C).
- the upstream filter aims to selectively transmit flavor-contributing components below the nicotine boiling point to the high-boiling components
- the downstream filter partially transmits the upstream filter through the upstream filter.
- the high-boiling components were selectively removed by condensation.
- Figure 11 compares the outflow of nicotine and aromatic amines when temperature is controlled in two stages with the result of one-stage heating at 150 ° C (HI 50), where the outflow of nicotine is approximately equal. Shown.
