CA 2286102
The invention relates to a device and method for cleaning and drying workpieces in a treatment vessel in which a reduced pressure can be provided. During the cleaning process, a liquid bath is formed in the treatment vessel, said liquid bath at least partially surrounding the workpieces, and cleaning fluid and optionally a gaseous medium are introduced into the treatment vessel under excess pressure via a spray unit. The workpiece support moves up and down or rotates so that the workpieces are subjected alternately to different cleaning processes in the liquid bath and a gas space located above said liquid bath.
L'invention concerne un procédé et un dispositif pour nettoyer ou sécher des pièces dans un contenant de traitement (1), dans lequel peut être produit un vide. Pendant le processus de nettoyage, un bain de liquide (50) est formé dans le contenant de traitement (1), ledit bain entourant les pièces au moins en partie. Le liquide de nettoyage et éventuellement une substance gazeuse sont introduits avec une surpression dans le contenant de traitement, pendant le processus de nettoyage, par l'intermédiaire d'une unité de pulvérisation (8a, 8b). Un mouvement alternatif ou un mouvement de rotation du porte-pièce permet d'acheminer les pièces en alternance vers différents processus de nettoyage dans le bain de liquide (50) et dans un espace gazeux (52) se trouvant au-dessus du bain de liquide.
