Method and apparatus for manufacturing aerosol-forming rod
Embodiments of the present disclosure relate to a method and an apparatus for manufacturing an aerosol-forming rod, and according to the present disclosure, it is possible to realize various aerosol-forming product properties, by utilizing the sheet-specific characteristics of each manufacturing process of reconstituted tobacco sheets and mixing two or more types of reconstituted tobacco sheets having different types, different physical properties, or different main components to control the physical properties and taste of the tobacco rod.
1. A method of manufacturing an aerosol-forming rod that is configured to generate an aerosol via heating, the method comprising:
providing a first reconstituted tobacco sheet manufactured by a first reconstituted tobacco sheet manufacturing process including a slurry process and a second reconstituted tobacco sheet manufactured by a second reconstituted tobacco sheet manufacturing process including a paper-making process or an extrusion process; and
manufacturing the aerosol-forming rod, which is configured to generate the aerosol via heating, by using a mixed reconstituted tobacco in which the first reconstituted tobacco sheet is mixed with the second reconstituted tobacco sheet at a predetermined mixing ratio,
wherein the first reconstituted tobacco sheet manufactured by the slurry process is mixed at a mixing ratio of 70% to 90%, and the second reconstituted tobacco sheet manufactured by a paper-making process or an extrusion process is mixed at a mixing ratio in a range of 10% to 30%.
2. The method of claim 1 , wherein physical properties of the aerosol-forming rod differ according to the predetermined mixing ratio.
3. The method of claim 2 , wherein the physical properties include at least one from among thickness, basis weight, porosity, hardness, resistance-to-draw, and filling power.
4. The method of claim 1 , wherein the second reconstituted tobacco sheet manufactured by the second reconstituted tobacco sheet manufacturing process is mixed at a mixing ratio of 30%, and the first reconstituted tobacco sheet manufactured by the first reconstituted tobacco sheet manufacturing process is mixed at a mixing ratio of 70%.
5. The method of claim 4 , wherein the first reconstituted tobacco sheet manufacturing process is a slurry process, and the second reconstituted tobacco sheet manufacturing process is a paper-making process or an extrusion process.
6. The method of claim 1 , wherein the first reconstituted tobacco sheet that is manufactured includes an aerosol-generating material.
7. The method of claim 6 , wherein 2% to 35% of the first reconstituted tobacco sheet is the aerosol-generating material.
8. The method of claim 1 , wherein the aerosol-forming rod does not include leaf tobacco shreds.
