Abstract

L'invention concerne un procédé de lyophilisation d'un produit préalablement congelé. Ce procédé consiste à fluidiser dans une enceinte 1 des particules d'adsorbant 12 dans un gaz porteur ayant une faible teneur en humidité, à disposer au sein de la couche fluidisée le produit 15 à lyophiliser et à ajuster la température de la couche fluidisée et la pression partielle de vapeur d'eau à l'intérieur de l'enceinte de sorte que la température d'interface des zones congelées du produit demeure à tout instant inférieure à la température de fusion commençante du produit sous la pression totale régnant dans l'enceinte, la pression partielle de vapeur d'eau étant constamment maintenue au-dessous de la pression correspondant au point triple de l'eau. Le procédé conforme à l'invention permet d'effectuer une lyophilisation à pression ambiante sans opérer à très basse température.
