Tobacco material including flavor material and method of manufacturing the tobacco material

Abstract

An embodiment of the present disclosure discloses tobacco material including: a center portion including a flavor material; and an outer portion including a tobacco mixture, wherein the outer portion surrounds the center portion.

1 . A tobacco material comprising:
 a center portion including a flavor material; and   an outer portion including a tobacco mixture and surrounding the center portion.   
     
     
         2 . The tobacco material of  claim 1 , wherein the center portion further includes tobacco particles, and the flavor material includes menthol. 
     
     
         3 . The tobacco material of  claim 1 , wherein the tobacco material includes about 5.0 wt % to about 8.0 wt % of water, with respect to a total weight of the tobacco material. 
     
     
         4 . The tobacco material of  claim 1 , wherein the center portion includes at least 95 wt % of the flavor material, with respect to a total weight of the center portion. 
     
     
         5 . The tobacco material of  claim 1 , wherein the center portion has a diameter of about 0.01 mm to about 0.3 mm, and the outer portion has a diameter of about 0.5 mm to about 1.99 mm. 
     
     
         6 . The tobacco material of  claim 1 , wherein the tobacco material has a viscosity of about 5 cp to about 200 cp. 
     
     
         7 . The tobacco material of  claim 1 , wherein the tobacco material has a surface roughness Ra of about 0.1 to about 10.0. 
     
     
         8 . The tobacco material of  claim 1 , wherein the tobacco material has a spherical shape. 
     
     
         9 . An aerosol generating article comprising:
 a tobacco rod comprising the tobacco material of  claim 1 ; and   a filter segment.   
     
     
         10 . A method of manufacturing a tobacco material, the method comprising:
 forming a center portion by growing a first composition; and   forming an outer portion to surround the center portion.   
     
     
         11 . The method of  claim 10 , wherein the forming of the center portion includes:
 spraying the first composition in a chamber; and   growing the sprayed first composition at a temperature of about 30° C. to about 60° C. and under a wind pressure equal to or lower than about 1.5 bar.   
     
     
         12 . The method of  claim 10 , wherein the forming of the outer portion includes:
 positioning the formed center portion in the chamber;   fluidizing the positioned center portion at a temperature of about 50° C. to about 90° C. and under a wind pressure equal to or lower than 1.5 bar; and   spraying a second composition onto the fluidized center portion.
