Method for producing cigarette containing clay minerals of loess and cigarette produced from the same

Abstract

This invention provides a method for producing a cigarette containing clay minerals of loess includes the steps of: (a) collecting loess powder by mixing a loess with aqueous solvent, filtering off filtered particles, and drying a filtrate; (b) sifting out the loess powder; (c) obtaining a homogenized suspension of loess by adding the sifted loess powder into the aqueous solvent, and shaking the suspension; and (d) applying the suspension into cigarette filter, filler or wrapper during the cigarette making process followed by drying. The cigarette containing the clay minerals of the loess produced in accordance with the method reduces the amount of nicotine, tar and carbon monoxide generated when smoked, adsorbs heavy metals such as cadmium and lead, reduces sub-stream giving out from cigarette, and radiates far-infrared ray peculiar to loess due to heat generated when smoked, thus contributing to non-smoker's as well as smoker's health.

What is claimed is:  
     
         1 . A cigarette comprising: clay minerals of loess produced by applying the loess into a cigarette filter, filler or wrapper.  
     
     
         2 . The cigarette as recited in  claim 1 , wherein the content of the clay minerals of the loess is in the range of from about 0.1 to about 10% of the cigarette weight on a dry weight basis.  
     
     
         3 . A method for producing a cigarette containing clay minerals of loess produced by applying the loess into a cigarette filter, filler or wrapper, the method comprising the steps of: 
 (a) collecting loess powder by mixing the loess with aqueous solvent, filtering off filtered particles and drying a filtrate;    (b) sifting out the loess powder;    (c) obtaining a homogenized suspension of the loess by adding the sifted loess powder into the aqueous solvent, and shaking the suspension; and    (d) applying the suspension into the cigarette filter, filler or wrapper during a cigarette making process, followed by drying.    
     
     
         4 . The method as recited in  claim 3 , wherein the loess powder includes clay minerals.  
     
     
         5 . The method as recited in  claim 3 , wherein the particle size of the sifted loess powder is in the range of from 1.0 to 1.5 μm.  
     
     
         6 . The method as recited in  claim 3 , wherein the ratio of the loess powder as added to the aqueous solvent is between 1:5 and 1:50.  
     
     
         7 . The method as recited in  claim 3 , wherein said step (d) includes the step of spraying the suspension of the loess onto the original cigarette filler produced by a filler making process.  
     
     
         8 . The method as recited in  claim 3 , wherein said step (d) includes the step of spraying the suspension of the loess onto the cigarette filter or impregnating the cigarette filter with the suspension of the loess, and drying thoroughly.  
     
     
         9 . The method as recited in  claim 3 , wherein the step (d) includes the step of spraying the suspension of the loess onto the wrapper or impregnating the wrapper with the suspension of the loess, and drying thoroughly.  
     
     
         10 . A method for producing a cigarette containing clay minerals of loess produced by applying the loess into a cigarette filter, filler or wrapper, wherein the content of the clay minerals of the loess is in the range of from about 0.1 to about 10% of the cigarette weight on a dry weight basis, the method comprising the steps of: 
 (a) collecting loess powder by mixing the loess with aqueous solvent, filtering off filtered particles and drying a filtrate;    (b) sifting out the loess powder;    (c) obtaining a homogenized suspension of the loess by adding the sifted loess powder into the aqueous solvent, and shaking the suspension; and    (d) applying the suspension into the cigarette filter, filler or wrapper during a cigarette making process, followed by drying.    
     
     
         11 . The method as recited in  claim 10 , wherein the loess powder includes the clay minerals.  
     
     
         12 . The method as recited in  claim 10 , wherein the particle size of the sifted loess powder is in the range of from 1.0 to 1.5 μm.  
     
     
         13 . The method as recited in  claim 10 , wherein the ratio of the loess powder as added to the aqueous solvent is between 1:5 and 1:50.  
     
     
         14 . The method as recited in  claim 10 , wherein said step (d) includes the step of spraying the suspension of the loess onto the original cigarette filler produced by a filler making process.  
     
     
         15 . The method as recited in  claim 10 , wherein said step (d) includes the step of spraying the suspension of the loess onto the cigarette filter or impregnating the cigarette filter with the suspension of the loess, and drying thoroughly.  
     
     
         16 . The method as recited in  claim 10 , wherein said step (d) includes the step of spraying the suspension of the loess onto the wrapper or impregnating the wrapper with the suspension of the loess, and drying thoroughly.
