Title (EN) VAPOR EXCHANGE
(FR) TRAITEMENT A LA VAPEUR
Abstract:
(EN) A process and apparatus for treating materials such as tobacco or the like by vapor exchange so that the material being treated does not develop partial staining n the material being treated due to condensation. Material to be treated is transported through a treatment zone bounded by a foraminous member that separates the treatment zone from an immediately adjacent zone of high density vapor. The vapor is flowed through the foraminous member and directly into the material at a continuous rate and with a major portion of the vapor flowed from the vapor zone being entrained by the material in the treatment zone. The continuous moderate flow of vapor into the bed of material produces rapid vapor ransfer and with excellent distribution of the vapor within the material being treated.
(FR) Procede et appareil de traitement de materiaux tels que le tabac et autres par transfert de vapeur de facon telle que le materiau traite ne se tache pas a cause de la condensation. Le materiau a traiter est transporte au travers d"une zone de traitement delimitee par un element permeable qui separe la zone de traitement d"une zone immediatement adjacente a forte densite de vapeur. La vapeur passe au travers de l"element permeable et va directement dans le materiau a un rythme continu, la majeure partie de la vapeur, passee de la zone de vapeur dans la zone de traitement, etant entrainee par le materiau. Le debit modere et continu de la vapeur dans le lit de materiau donne un transfert de vapeur rapide et une excellente distribution de la vapeur rapide dans le materiau traite.
