Abstract

Dispositif de vaporisation portatif comportant une chambre de chauffage destinée à chauffer un substrat de composé volatil de façon à dégager de la vapeur comprenant le composé volatil. La chambre de chauffage comprend une ouverture refermable, par exemple à l'aide d'un bouchon, pour recevoir le substrat. La chambre de chauffage comprend également des canaux de captage destinés à admettre de l'air dans celle-ci. Le dispositif de vaporisation portatif comporte en outre une chambre à vapeur montée sur la chambre de chauffage de façon à être en communication fluidique avec celle-ci pour recevoir la vapeur captée à partir de celle-ci et est dotée d'une sortie de vapeur destinée à relâcher la vapeur comprenant le composé volatil. En appliquant de la chaleur à l'extérieur de la chambre de chauffage du dispositif de vaporisation portatif, à l'aide d'une flamme ou d'un dispositif de chauffage quelconque, le confinement résultant de la chambre de chauffage et l'émissivité de ses parois créent une chaleur uniforme sur l'étendue du substrat qui y est déposé. Le fait de chauffer le substrat de cette manière permet une grande efficacité d'extraction d'éléments organiques volatils non dilués.
