An apparatus and method for dehydrating biological materials, such as vaccines and microorganism cultures, in which the materials are dehydrated in an evacuated container which is in a microwave waveguide that is open to the atmosphere. The apparatus comprises means for freezing the container of biological material, a microwave generator, a waveguide, means for introducing the container into the waveguide, means for applying a vacuum to the container and means for removing the dehydrated material from the waveguide. In the method of the invention, the container of biological material is put in a microwave waveguide open to the atmosphere, a vacuum is applied to the container, the material is frozen and is radiated to dehydrate it. The dehydrated material is then removed from the waveguide.
L'invention concerne un appareil et un procédé de déshydratation de matières biologiques, comme des vaccins et des cultures de micro-organismes, lesdites matières étant déshydratées dans un récipient sous vide placé dans un guide dondes pour micro-ondes qui est ouvert sur latmosphère. Lappareil comporte un moyen destiné à congeler le récipient de matière biologique, un générateur de micro-ondes, un guide dondes, un moyen destiné à introduire le récipient dans le guide dondes, un moyen destiné à appliquer un vide au récipient et un moyen destiné à retirer la matière déshydratée du guide dondes. Dans le procédé selon linvention, le récipient de matière biologique est placé dans un guide dondes pour micro-ondes ouvert sur latmosphère, on fait le vide dans le récipient, la matière est congelée et irradiée afin de la déshydrater. La matière déshydratée est ensuite retirée du guide dondes.
