Abstract: There is provided an aerosol generating device, comprising an inhalation outlet; a chamber for holding a material, the material capable of generating a vapour when heated; a heater for heating material held in the chamber; an air inlet connected by an air inlet passage to the chamber; a vapour-cooling module providing a fluidic connection between the chamber and inhalation outlet, the module configured to cool a vapour passing there through. In use, suction at the inhalation outlet causes air to enter the chamber via the air inlet, thereby transporting the vapour generated in the chamber through the vapour-cooling module to the inhalation outlet, such that the temperature of the vapour exiting the device through the inhalation outlet is substantially lower than the temperature of the vapour generated in the chamber. The aerosol generating device thereby provides a means whereby a vapour generated in the chamber is substantially cooled during transport from the chamber through the mouthpiece to the user.

Abstract: A method for producing a vaporisable material comprising plant fibres for use in a vapour generating device which generates a vapour by heating the vaporisable material is disclosed. The method comprises reducing the particle size of the plant fibres to less than 1.5 mm and mixing plant fibres of at least two ranges of particle size. The invention also relates to vaporisable material for use in a vapour generating device obtainable by the method.
