  • a heat mat 35 may be placed beneath the vessel 1 to heat the contents thereof.
  • the increase in temperature obtained by applying heat to the vessel 1 leads to an increase in the pressure inside the vessel 1 assuming that the amount of air held inside the vessel 1 is kept substantially constant.
  • Alternative heat sources that may be employed to supply heat to the vessel 1 will be apparent to those skilled in the art.
  • the vessel 1 has been heated to temperatures of approximately 45 degrees Celsius (° C.).
  • the tobacco industry product 5 may be treated with water prior to loading into the annular chamber 20 so that the tobacco industry product 5 does not dry out excessively.
  • the pressure may be released and the tobacco industry product 5 removed.
  • tobacco rods may be formed for use in smoking articles in a manner well known in the art.
  • the tobacco thus treated provides a different taste and aroma profile compared with tobacco that has not undergone this process.
  • the tobacco storage vessel 40 shown in FIG. 3 comprises an chamber 41 wherein the tobacco industry product 5 may be stored.
  • a mesh shelf 42 may be located inside the vessel 40 to support the tobacco industry product 5 thereon.

  • the air is fed to the lower portion of the internal chamber 100 through the internal pipe 140 and passes through the water stored in the part of the chamber 100 below the wire mesh 110 which supports the botanical product 10 .
  • the heat jacket 120 and heat mat 130 heat the storage vessel to approximately 90° C.
  • the applied heat and the air flow act to evaporate a substantial proportion of the water stored in the storage vessel 60 creating water vapour.
  • the air and water vapour are forced upwards through the wire mesh 110 and through the botanical product 10 .
  • the air is then forced out of the vessel 60 through the pipe 90 b that connects the vessel 60 with the mixing drum 70 which contains a quantity of tobacco industry product 5 to be infused with the botanical product 10 .
  • the mixing drum 70 is at a lower temperature than the storage chamber 60 therefore water vapour conveyed into the drum 70 from the storage chamber 60 through the pipe 90 b condenses in the drum 70 .
  • the drum 70 may be rotated about a cylindrical axis 145 . This allows a thorough circulation of the tobacco industry product 5 and condensed water within the drum 70 . In this way the tobacco industry product 5 becomes infused with sensate constituents from the botanical product 10 . The process described above is continued until all the water stored in the storage chamber 60 has been evaporated.
  • FIG. 5 An alternative storage vessel 60 is shown in FIG. 5 .
  • the vessel 60 is elongate with air from the peristaltic pump 80 entering the vessel from an inlet 150 located in the lower portion of the vessel 60 .
