Abstract
L'invention porte sur un appareil et une méthode de traitement des déchets médicaux comportant un contenant sous pression (A) allongé et cylindrique qui présente une entrée (30) et un élément de fermeture (40) de l'entrée. Un fût cylindrique allongé (D) est monté sur le contenant (A) de façon à tourner dans chaque sens. Le fût (D) est incliné par rapport à l'horizontale, de sorte que l'entrée (50) est surélevée. Un élément hélicoïdal (80) est placé autour du fût, sur sa surface interne, de sorte qu'il éloigne les déchets de l'entrée (50) pendant la rotation dans un premier sens, et qu'il les rapproche de l'entrée du fût (50) pendant la rotation opposée. Il est utilisé conjointement avec des palettes de levage (70) qui permettent d'obtenir un mélange homogène des déchets. L'humidité et la chaleur, typiquement de la vapeur (90), sont utilisées pour favoriser le traitement des déchets. La décharge des déchets entièrement traités se fait pendant la rotation du fût dans le second sens.
