Vaporisable Material and Capsule

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.

         2 . A method according to  claim 1 , wherein the step of reducing the particle size of the plant fibres comprises a step of cutting the plant fibres. 
     
     
         3 . A method according to  claim 2 , wherein the method comprises a  1  further step of sieving the plant fibres after the cutting step to separate fibres of different particle sizes. 
     
     
         4 . A method according to  claim 1 , further comprising a step of drying the plant fibres to a moisture content of about 5 wt % or less. 
     
     
         5 . A method according to  claim 1 , comprising the following steps:
 i. drying the plant fibres to a moisture content of about 5 wt % or less;   ii . cutting the plant fibres;   iii. sieving the cut plant fibres after the cutting step to separate the plant fibres of different particle sizes;   iv. adding at least one humectant to the plant fibres; and   v. mixing the plant fibres with the humectants.   
     
     
         6 . A method according to  claim 1 , wherein the vaporisable material comprises tobacco.
