Abstract

L'invention concerne un système extracteur-mélangeur. Selon l'invention, un fluide actif est déchargé par un ajutage sous la forme d'un jet creux engendrant une aspiration, entraînant une matière fluide qui se mélange au fluide actif dans une chambre de mélange. Une dérivation peut être prévue autour de l'ajutage, pour permettre de commander la quantité de matière entraînée dans le système. Un moyen de recyclage peut également être prévu pour permettre d'augmenter la concentration du mélange ou de changer l'état de la matière en mélange. Le système convient pour réaliser des dispersions, des soudons ou des mélanges fluides.
