Abstract

Un solvant réfrigéré est alimenté à travers une chemise de refroidissement autour d'un récipient d'extraction d'éléments essentiels. Après la circulation à travers la chemise de refroidissement, le solvant est réfrigéré et au moins une partie du solvant est introduite dans la cuve d'extraction, dans laquelle des éléments essentiels se dissolvent dans le solvant. En aval du récipient d'extraction, après le traitement du milieu adsorbant, le mélange d'huile et de solvant extrait est filtré, dans un état réfrigéré, à travers une ou plusieurs unités de filtration. Une unité de filtration peut être un système de filtres orientés verticalement de taille de pore décroissante scellés et isolés de l'atmosphère. Du gaz sous pression est utilisé pour forcer l'huile et le solvant à travers les filtres. Chaque étage de filtration a un couvercle amovible, qui permet un accès pratique pour remplacer la cartouche filtrante sans perturber les parois latérales thermiquement isolées de l'étage de filtration.
