Abstract

L'invention, qui concerne un procédé de nettoyage par mousse contrôlée, concerne également un équipement destiné au lavage, à la désinfection et à la stérilisation. Une solution de travail est chauffée par un composant chauffant de façon à produire de la mousse. Une grande quantité de mousse est ainsi formée directement dans une chambre de nettoyage ou introduite dans la chambre de nettoyage depuis l'extérieur. Le contrôle de la mousse de nettoyage est conçu pour que la saleté, les substances nuisibles et les microorganismes adhérant à un objet nettoyé placé dans chambre de nettoyage soient suffisamment en contact avec les agents actifs présents à la surface de la mousse dans la chambre de nettoyage. Ces saletés, substances nuisibles et microorganismes sont alors séparés, détruits ou tués selon diverses modalités d'action, puis isolés avec la mousse de la surface de l'objet nettoyé au fur et à mesure de la baisse de la pression et de la température à l'intérieur de la chambre de nettoyage, et enfin déchargés à l'extérieur de la chambre de nettoyage. L'équipement de nettoyage conçu selon la technologie de l'invention s'avère plus efficace, plus rapide pour le lavage, moins gourmand en énergie et en eau, et moins bruyant et moins cher que les produits conventionnels. L'invention convient ainsi particulièrement au nettoyage, à la désinfection et à la stérilisation de divers objets nettoyés tels que la vaisselle, les instruments médicaux, les vêtements, les pièces industrielles, les antiquités, et la peau des animaux de compagnie, des animaux en général et des humains.
