Description

A tobacco added loess and its manufacturing method

Technical field

The present invention relates to tobacco added loess as a ingredient, and particularly manufacturing methods for the tobacco that the concentrations of harmful chemicals in the tobacco smo are decreased by the reactions with the elements of loess.

Background Art According to a scientific report on the tobacco smoke, contains more than 3,800 chemicals, many of them are poisonou Among them 43 chemicals that are known to cause cance Especially, carbon monoxide in the smoke is an odourless , colourle and poisonous gas. Carbon monoxide interferes with the uptake oxygen in the lungs and with its release from the blood to the tissue that need it.

When carbon monoxide is inhaled , it combines wit hemoglobin in the blood. It reduces the amount of oxygen availab to the body's vital organs. In heavy smokers, carbon monoxide ca severely reduce the amount of oxygen carried by the blood . Oxyge levels may be reduced by as much as 15 percent.

Most smokers acknowledge the harm of tobacco but hard stop the smoking by oneself because of the addiction . For th reason , merchandise related to nonsmoking aids such as tobacc pipes, nicotine removers, . , and chewing gums are actively investigat for the health of smoker. But unfortunately most of nonsmoking ai are ineffective because they can not prevent the poisonous chemica of smoke in a primary way.

For the foregoing reasons, there is a need for a tobacco s that the harmful chemicals in the smoke are easily and safely reduce for the health of smokers or nonsmokers exposed to the tobacc smoke.

Disclosure of Invention The present invention is directed to manufacturing a tobacc added loess that reduce the carbon monoxide in the tobacco smoke . Consequently, the reduction of the carbon monoxide content in the smoke and the adsorptions of harmful chemicals into the porous loess are achieved by manufacturing the loess as an ingredient of tobacco which is main embodiment of present invention .

Loess is well known as antitoxin material in the native medicin in Korea. Recently the efficacies of loess is widely acknowledged a a biomaterial . The application of this material covers the production related to beds , a cloths and especially constructing materials.

Loess consists 40-80% of Quartz, 1 0-20% of Mica a Feldspar, 5-35% of Carbonate Mineral and 2-5% of Silt. In formation, silt contains the heavy minerals such as Hornblend Apatite, Biotite, Chlorite, Kyanite, Epidote, Garnet, Augite, Ruti Sillimanite, Staurolite, Tourmaline, and Zirocon . The chemic ingredient of the loess consists 50-60% of Si0₂, 8- 12% of Al₂0 2-4% of Fe₂0₃, 0.8-1 .1 % of FeO, 4- 1 6% of CaO , 2 ~ 6% of Mg 0.5% of Ti0₂ and MnO. Generally it has 10- 15% of water content a 50-55% of the porosity having a decreasing value with the increasin water concentration . Applying these properties of loess to tobacco, new approach for making tobacco is achieved with the presen embodiments.

Consequently, it is an object of the present invention provide a tobacco which reduce the harmful chemicals in the smok while the taste of tobacco is not changed. The active iron oxide (Fe₂θ3, FeO) of loess in the tobacco burning react with the carbo monoxide so that the content of CO is decreased resulting increase of C0₂ while in the smoking.

Another object of the present invention is to provid efficacies concerning the adsorbing operation on the harmf chemicals. The large porosity of loess adsorb the poisonou chemicals in the tobacco smoke. In the microscopic view, the conta between tobacco smoke and the refined loess in the fine mixture bring the adsorption of harmful chemicals into the porous loess s that the porous loess operate on harmful chemicals in smoke actin as molecular sieves.

A further object of the present invention is directed to enhance innocuous content in the tobacco smoke. Not only the health for smoker but also for nonsmoker's exposed to the smoke should be protected in a primary way. The less out gas rate and content of CO with the ingredient help to diminish the harmful effect of the smoke.

Other objects and further scope of applicability of the presen invention will become apparent from the detailed description give hereinafter.

Chemical formula 1

Fe₂0 + 3CO → 2Fe + 3C0₂ FeO + CO → Fe + C0₂ CaO + CO → Ca + C0₂ MgO + CO → Mg + C0₂

According to the experiment results, the concentration of CO containing in the ordinary tobacco smoke hold over 250 ppm . But the results according to the present invention of tobacco added loess show that the concentration indicate the values under 60ppm .

As seen on the tangible results, the loess with the appropriate amount of iron oxides as a vital ingredient of tobacco operate the reduction for the CO concentration remarkably. While in the smoking , FeO , Fe₂θ3, CaO and MgO of loess are not stable compounds in the burning temperature of 900- 1 ,000 Celsius degree. Therefore the reactions between the carbon monoxide and oxides compounds in the loess conducts the reduction of carbon monoxide. The oxygen compounds in the loess or iron oxides (Fe₂θ3, FeO) inserted for the reinforcement easily react in the high temperature with the carbon monoxides providing the increase of carbon dioxides in the smoke as shown on the chemical formula 1 .

Industrial Applicability As illustrated in the above, the present invention is ve practical and useful in that the loess can reduce the harmful an poisonous smoke in a certain way. Therefore this invention decreas the pollution caused by the poisonous smoke of tobacco remarkab The chemicals in the tobacco smoke are known to cause headache nausea, vomiting, abdominal pain , diarrhoea, and cancer. Especia Carbon monoxide in tobacco smoke is an odorless, colourles poisonous gas. The decrease of carbon monoxide and toxic smok by the chemical reactions and the adsorption by the porous loes minimize the danger of poisonous effect of smoking . This prima protection from the harmful smoke is accomplished not only f smoker health but also for nonsmoker environment. These advantag strongly support the industrial applicability of the present invention .
