Abstract

Le secteur technique de l'invention est celui du traitement par le froid d'objets à broyer. Un agencement de réfrigération comporte une tour de développement de gaz et de vapeurs munie de chicanes inclinées de façon réglable pour effectuer une répartition de la charge des objets à traiter et d'une chicane mobile actionnée par un vérin hydraulique commandé par une jauge de contrainte pour la descente d'un poids désiré d'objets dans un bain de gaz liquéfié se trouvant dans un récipient alternativement en position haute pendant l'immersion des objets et en position basse pendant leur déchargement vers un broyeur, par l'intermédiaire d'un volet de fermeture automatique. Application au traitement par le froid d'objets composites avant leur broyage, en vue de la récupération de leurs éléments constitutifs.
