Abstract

L'invention concerne un procédé et un dispositif permettant de mélanger un second milieu à un premier milieu. Ce procédé et ce dispositif sont particulièrement avantageux quand ils sont utilisés pour mélanger différents produits chimiques, aussi bien liquides que gazeux, ou pour mélanger de la vapeur à une suspension de pâte dans l'industrie de transformation du bois. Selon l'invention, on amène le premier milieu dans le châssis (10) du mélangeur, on le mélange et on le sort dudit châssis (10), le flux du milieu qui entre dans le châssis (10) faisant tourner un rotor (20) à rotation libre placé à l'intérieur.
