The present invention relates to a citrus filter, a citrus using the same, and a manufacturing method thereof, and more particularly, to a citrus filter including silver (Ag) and a ginkgo leaf extract, a citrus using the same and a manufacturing method thereof.

Tobacco is a natural plant containing nicotine and is a source of preference. In herbal medicine, tobacco leaves are used as medicinal herbs, and specifically used to relieve indigestion and pain. Cigarettes include cigarettes, pipes, snuffs and chewing tobacco.

Tobacco smoke contains various organic compounds such as nicotine and tar, which are harmful to the human body, and the content of carbon monoxide and carbon dioxide is 1000 times higher than that of general air. Therefore, a technique has been attempted to lower the content of harmful components and carbon monoxide contained in such cigarette smoke.

Korean Patent Publication No. 2006-0056473 discloses a pistol containing silver nano powder. However, the above technology does not describe the effects of cigarette smoke when silver nano is used for cistern, and simply discloses the results of the antimicrobial activity test of the medium containing silver nano part.

Korean Patent Publication No. 2003-0010166 discloses a filter for cinnamon containing ginkgo leaf powder, but discloses only a reduction effect of tar and nicotine.

Therefore, there is still a need for a cigarette filter that can remove the harmful gases such as carbon monoxide in addition to the harmful organic compounds from the cigarette smoke to substantially reduce the harmful substances to the smoker while maintaining the taste of the cigarette.

According to one embodiment of the present invention, the silver (Ag) may be in the form of silver ions, or in the form of silver nanoparticles having an average particle diameter of 0.5 to 20 nm, or a mixture thereof. The silver nanoparticles may be prepared by various methods such as an electrochemical method, a chemical reduction method, and the like. For example, the silver nanoparticles may be prepared by subjecting pure silver having a purity of 99.9% or more to a voltage of about 1 to 200 V and electrolyzing or reducing silver ions dissolved in a solution. The particle size of the silver nanoparticles may be adjusted according to specific manufacturing conditions. As for the average particle diameter of the said silver nanoparticle, 1-20 nm is preferable, More preferably, it is 2-20 nm, Most preferably, it is 2-14 nm. The average particle diameter of the said silver nanoparticles is preferable for achieving the objective of this invention. The silver ions or silver nanoparticles may be supported in the pores of the activated carbon or adsorbed onto the surface of the activated carbon.

The activated carbon is not particularly limited as long as the activated carbon is used in the art as a porous material obtained by carbonizing a coconut shell or the like.

According to another embodiment of the present invention, the specific surface area of the activated carbon is preferably 100 to 2000 m ² / g, more preferably 800 to 1200 m ² / g. The total pore volume of the activated carbon is preferably 0.1 to 1 cc / g, more preferably 0.5 to 0.6 cc / g. The specific surface area and total pore volume of the activated carbon are preferred for achieving the object of the present invention. Although the average pore diameter of the said activated carbon is not specifically limited, 10-2000 micrometers is preferable, More preferably, it is 10-1000 micrometers, Most preferably, it is 10-100 micrometers.

According to another embodiment of the present invention, the ginkgo biloba extract is preferably extracted from the ginkgo pulverized powder for 5 to 7 hours by steam at a pressure of 120 ~ 150kg / ㎠. That is, the ginkgo biloba extract of the present invention is obtained by being separated from the ginkgo pulverized product by pressurized steam. The pressure and temperature range used for the extraction of the ginkgo biloba extract is suitable for achieving the object of the present invention.

According to another embodiment of the present invention, the ginkgo leaf extract preferably comprises a flavone glycoside-based compound, a terpene lactone-based compound, and a zinc glycolic acid-based compound. Specifically, when the ginkgo biloba extract is obtained in the form of ginkgo biloba extract, the flavone glycoside-based compound 2 ~ 4g per 100g ginkgo biloba extract, terpene lactone compound 0.1 ~ 1g, 10 ~ 20g ginkgolic acid-based compound and the remaining amount of water It is preferable.

The manufacturing method will be described in more detail. First, the ginkgo biloba leaves used in the preparation of the ginkgo biloba powder may be green or yellow. The desired ginkgo biloba is washed with water, dried and then high and crushed in the grinder. The crushed ginkgo biloba filter using a sieve of 150 ~ 180 mesh (mesh) using only fine powder less than the size. The pulverized ginkgo biloba powder is placed in a predetermined square plate and stacked in several layers at intervals in the reactor. Water is contained at the bottom of the reactor, and a pressure gauge and a valve for discharging steam are installed at the top of the reactor. The reactor is sealed and the bottom of the reactor is heated. When steam is generated to fill the reactor and the pressure reaches the level of 120 ~ 150kg / ㎠ to maintain the state for 5 to 7 hours. After the time elapses, the valve at the top of the reactor is opened to release water vapor containing the ginkgo leaf extract. Subsequently, the released water vapor passes through a cooler to obtain a ginkgo leaf extract containing a liquid ginkgo leaf extract. On the other hand, a silver nano dispersion liquid of predetermined concentration is prepared. The concentration of the silver nano may be appropriately adjusted as necessary. While moving activated carbon evenly distributed on a conveyor belt, the ginkgo biloba extract and the silver nano dispersion are sequentially sprayed to carry them on the activated carbon. The conveyor belt is preferably mixed evenly by activated carbon by vibration. The ginkgo biloba extract and silver nano-supported activated carbon is preferably dried naturally in the air.

The manufacturing method of the cigarette filter containing the said activated carbon is the same as the general method in the art. For example, a spinning solution comprising a polymer such as an organic solvent, cellulose acetate, and the like, and activated carbon carrying ginkgo leaf extract and silver nanoparticles according to an embodiment of the present invention are prepared. The spinning solution is used to spin by dry spinning in a conventional conventional acetate tow spinner. The formed polymer filaments are bonded in bands, placed in a crimper under pressure, and crimped and dried. The tow of the crimped filaments is first loosened using a filler and then compressed into a bale. The acetate tow is introduced into a rod filter maker to prepare a rod filter.

The activated carbon may be added at the time of spinning or added in other manufacturing steps without entering the spinning solution. The filter may be manufactured in any form used in the art and may be manufactured by other methods. For example, the rod-shaped filter including the activated carbon may be used in conjunction with a filter not containing the activated carbon. Another method of making the filter can be found, for example, in USP20050287653A.

Although only a mono filter including activated carbon is exemplified in the above embodiment, it is obvious that the filter may be manufactured by various filters such as a double filter, a triple filter, and the like.

According to another embodiment of the present invention, the pistol includes the above cistern filter. The rod-shaped filter according to the embodiment of the present invention is bonded to the tobacco tobacco cut winding wound to manufacture a cigarette. The manufacturing method of the cistern is not particularly limited as long as it is a known manufacturing method in the art, and the details thereof are described in more detail, for example, USP 7117871 and the like.
