The invention concerns a method for separating and drying microparticles initially dispersed in liquid phase comprising steps which consist in: providing a preparation comprising microparticles dispersed or suspended in liquid phase in a filtering vessel (12) arranged inside a chamber (6); filtering a fraction of the liquid phase (52) through the vessel in the chamber; and varying the temperature and the pressure in the entire chamber to freeze-dry the filtered preparation in the vessel maintained in the chamber.
Le procédé pour séparer et sécher des microparticules initialement dispersées en phase liquide comprend les étapes consistant à : disposer une préparation (48) comprenant des microparticules dispersées ou suspendues en phase liquide dans un récipient filtrant (12) disposé à l'intérieur d'une enceinte (6); filtrer une fraction de la phase liquide (52) à travers le recipient dans l'enceinte; et faire varier la température et la pression dans toute l'enceinte pour lyophiliser dans le récipient maintenu dans l'enceinte, la préparation filtrée.
