Abstract

There is described an apparatus for heating an aerosol generating material to generate an inhalable aerosol or gas. The apparatus includes a housing; a receptacle within the housing, the receptacle including one or more cavities, each cavity for containing an aerosol generating material; and a heating arrangement including one or more heater elements for heating aerosol generating material contained in the one or more cavities to generate an inhalable aerosol or gas. The one or more heater elements are located externally of the one or more cavities.

First claim

The invention claimed is:

1. A method of manufacturing an aerosol generating the consumbable comprising an aerosol generating material contained within a receptacle, wherein the consumable is configured to be received by an apparatus for heating the aerosol generating material contained with the receptacle material, the method of manufacturing the consumable comprising:
providing, during manufacturing of the consumable, one or more cavities of the receptacle with a relatively wet aerosol generating material, the relatively wet aerosol generating material comprising a percentage of water; and
treating, during the manufacturing of the consumable, the relatively wet aerosol generating material to reduce the percentage of water of the relatively wet aerosol generating material during the manufacturing to generate a relatively dry aerosol generating material in the one or more cavities,
wherein the consumable is a disposable consumable, configured to be disposed of once the aerosol generating material in the receptacle has been exhausted.

2. The method according to claim 1 , wherein the relatively wet aerosol generating material comprises a wet gel, a slurry, or a liquid.

3. The method according to claim 1 , wherein the relatively dry aerosol generating material comprises a dry gel or a powder.

4. The method according to claim 1 , wherein the treating comprises heating the relatively wet aerosol generating material.

5. The method according to claim 1 , wherein the treating comprises heating the receptacle in an oven.

6. The method according to claim 1 , wherein the treating comprises freeze drying the relatively wet aerosol generating material in the one or more cavities of the receptacle.

7. The method according to claim 1 , comprising:
providing a protective barrier on the receptacle to seal the relatively dry aerosol generating material in the one or more cavities.
