Definitions

  • the invention relates to a method for treating tobacco, comprising conditioning the tobacco, wherein the tobacco is moistened, and drying the conditioned tobacco.
  • the invention further relates to a device for storing tobacco in such a method.
  • the object of the invention is to provide a method for treating tobacco and a device therefor which achieve an improvement in the quality and the taste of the tobacco thus treated, in particular without additives such as flavor or casings.
  • the invention solves this problem with the features of the independent claims.
  • the storage according to the invention of the tobacco between conditioning and drying in a Temperature of at least 45 ° C over a period of at least 30 minutes the taste of tobacco, especially of low-grade tobacco, significantly improved.
  • the conventional conditioning which usually takes less than 10 minutes
  • the effect of the invention is achieved by the influence of temperature over a much longer period of at least 30 minutes.
  • An addition of flavor or casings is not required.
  • the proportion of low-grade tobacco treated in accordance with the invention in a blend can be increased without impairing the quality or the taste, as a result of which overall costs can be saved.
  • the storage is carried out according to the invention in a substantially closed storage device in order to maintain a preferred constant storage atmosphere and to avoid energy losses.
  • substantially closed means, in particular, that the tobacco feed / outlet opening is closed during storage.
  • the Tabakzu wool- / - outlet opening is therefore closed, for example by means of a lid and preferably sealing.
