An apparatus and process for rapidly removing organic components from films. The apparatus comprises a heating chamber (13) having one or more heating elements (68). A pair of spaced-apart electrodes (76, 11) are provided for establishing an electric field in the heating chamber. The process comprises heating the film in the presence of the electric field to a temperature sufficient to cause the removal of organic components from the film. Un procédé et un appareil sont utilisés pour éliminer rapidement des composants organiques contenus dans des pellicules. L'appareil comprend une chambre de chauffage (13) ayant un ou plusieurs corps chauffants (68). Une paire d'électrodes espacées (76, 11) établissent un champ électrique dans la chambre de chauffage. Le procédé comprend le chauffage de la pellicule en présence du champ électrique jusqu'à une température suffisante pour provoquer l'élimination des composants organiques contenus dans la pellicule.
