Abstract
L'invention concerne un dispositif de fonte et de centrifugation capable de fondre et de centrifuger un matériau polymère biodégradable. Ce dispositif est caractérisé en ce que le matériau polymère biodégradable est fondu au moyen d'un mécanisme de fonte (4) comprenant une vis (16) logée dans un cylindre disposé de manière verticale (8) et étant coaxiale avec celui- ci (8), la vis (16) étant entraînée de manière rotative par un mécanisme d'entraînement rotatif (7), ainsi qu'une rainure hélicoïdale (17) d'au moins une rangée formée au niveau de la surface périphérique de celle-ci, et en ce que le matériau polymère biodégradable fondu est déchargé de manière verticale à partir de l'orifice de sortie d'une buse (10) disposée de manière coaxiale avec le cylindre (8), aux fins de centrifugation.
