Smoking article and aerosol-generating system

Abstract

A smoking article according to an example embodiment include a medium receiver filled with a plurality of medium granules, a humectant receiver located on one side of the medium receiver and configured to generate an aerosol, and a filter located on the other side of the medium receiver. The plurality of medium granules are 0.25 mm or more in diameter.

1 . A smoking article comprising:
 a medium receiver filled with a plurality of medium granules;   a humectant receiver located on one side of the medium receiver and configured to generate an aerosol; and   a filter located on another side of the medium receiver,   wherein the plurality of medium granules are 0.25 mm or more in diameter.   
     
     
         2 . The smoking article of  claim 1 , wherein the plurality of medium granules comprise tobacco granules. 
     
     
         3 . The smoking article of  claim 1 , wherein the medium granules are 0.60 mm or less in diameter. 
     
     
         4 . The smoking article of  claim 3 , wherein the medium granules are 0.425 mm or more in diameter. 
     
     
         5 . The smoking article of  claim 1 , wherein the medium receiver is configured by folding a flat sheet, to which the plurality of medium granules are applied, multiple times. 
     
     
         6 . The smoking article of  claim 5 , wherein a humectant is applied to one surface of the flat sheet. 
     
     
         7 . The smoking article of  claim 1 , wherein the medium receiver is formed by a method comprising applying a humectant to one surface of a flat sheet, disposing the plurality of medium granules on the one surface of the flat sheet, to which the humectant is applied, folding the one surface of the flat sheet to face each other, additionally folding the flat sheet multiple times, and wrapping, with a wrapper, the flat sheet folded multiple times. 
     
     
         8 . The smoking article of  claim 1 , wherein the filter comprises:
 a first filter having a cavity therein; and   a second filter fully filled with a filtration material.   
     
     
         9 . The smoking article of  claim 1 , wherein the plurality of medium granules are manufactured by a fluidized bed granulation process in which a spraying direction of a liquid binder and a flow direction of fluidized air face each other. 
     
     
         10 . An aerosol-generating system comprising:
 a smoking article; and   an aerosol-generating device,   wherein the smoking article comprises:
 a granule receiver filled with a plurality of tobacco granules; 
 a humectant receiver located on one side of the granule receiver and configured to generate an aerosol; and 
 a filter located on another side of the granule receiver, 
   wherein the aerosol-generating device comprises:
 an elongate cavity configured to accommodate the smoking article; 
 a heater configured to heat at least a portion of the granule receiver and the humectant receiver in the smoking article; and 
 a controller electrically connecting to the heater, and 
 wherein the plurality of tobacco granules are 0.25 mm or more in diameter. 
   
     
     
         11 . The aerosol-generating system of  claim 10 , wherein the tobacco granules are 0.425 mm or more and 0.60 mm or less in diameter. 
     
     
         12 . The aerosol-generating system of  claim 10 , wherein the plurality of tobacco granules are manufactured by a process in which a spraying direction of a liquid binder and a flow direction of fluidized air face each other.
