Abstract

L'invention concerne un dispositif destiné principalement au chargement et au déchargement de la surface de support (3') de la chambre de séchage (2) d'une installation de lyophilisation se trouvant dans une position de hauteur définie, la position de déchargement. Ledit dispositif est caractérisé par un chariot (8) agencé légèrement au-dessus de ladite surface de support, s'étendant de manière transversale par rapport à une direction de déplacement (8') pendant un chargement ou un déchargement et de manière parallèle par rapport à la surface de support, et formant un bord de guidage mobile pour les récipients de séchage (5), ainsi que par des éléments de guidage (7) agencés des deux côtés de la surface de support (3'), s'étendant de manière parallèle par rapport à ladite direction de déplacement et formant des bords de guidage fixes pour les récipients de séchage (5). Deux moteurs linéaires dont les parties secondaires (18) respectives sont fixées solidement aux extrémités bilatérales du chariot (8) et sur lesquels sont montés simultanément les éléments de guidage (7) logeant les parties primaires, servent d'entraînement pour le chariot (8). Tous les composants du dispositif ainsi défini se trouvent à l'intérieur de la chambre de séchage (1), ce qui permet d'obtenir une structure mécanique exceptionnellement simple présentant une faible usure. La structure d'un tel dispositif permet, à l'intérieur de la chambre de séchage (2), la mise en œuvre d'éléments de guidage (7) latéraux indépendants de la surface de support et convient pour un équipement ultérieur progressif des installations de lyophilisation existantes en vue d'une utilisation de plusieurs chariots, une mobilité latérale des éléments de guidage (7), c'est-à-dire destinée à être configurée de manière transversale par rapport à la direction de déplacement (8'), etc. Etant donné que les éléments essentiels de ce dispositif peuvent être réalisés sous la forme d'une structure hermétique et peuvent ainsi être soumis à une stérilisation, on obtient une facilité de manipulation sûre également du point de vue de l'hygiène.
