The invention relates to a process for extracting fixed and mineral oils, and/or essential oils, from materials using a process of solvent extraction which is performed under pressure. The solvent is iodotrifluoromethane or iodotrifluoromethane in combination with a co-solvent. The invention also relates to an apparatus for performing the extraction of fixed and mineral oils, and/or essential oils. Substantial reductions in or elimination of the normally high latent heat of solvent evaporation may also be achieved simply by raising or lowering the temperature of or simply by adding or removing "sensible" heat from the solvent at appropriate points during its re-circulation.
La présente invention concerne un processus d'extraction à partir de substances d'huiles fixes ou minérales et/ou d'huiles essentielles, mettant en oeuvre un processus d'extraction d'un solvant se déroulant sous pression. Ce solvant est l'iodotrifluorométhane, seul ou combiné à un co-solvant. L'invention concerne également un dispositif permettant de réaliser l'extraction d'huiles fixes ou minérales et/ou d'huiles essentielles. On peut obtenir d'importantes réduction voire l'élimination de la chaleur latente généralement élevée de l'évaporation du solvant simplement par augmentation ou réduction de la température du solvant en certains points appropriés au cours de sa remise en circulation, ou simplement en ajoutant ou en supprimant de la chaleur </= sensible >/= dudit solvant.
