Title
(EN) MIXING DEVICE AND RELATED METHOD FOR MIXING OR EMULSIFYING AT LEAST TWO SUBSTANCES
(FR) DISPOSITIF DE MÉLANGE ET PROCÉDÉ ASSOCIÉ POUR MÉLANGER OU ÉMULSIFIER AU MOINS DEUX SUBSTANCES
Abstract
(EN)
A mixer comprises a mixing chamber (2), access ports (3) adapted to enable access to the mixing chamber and propulsion means (4) acting on the mixing chamber for moving a mixture M or at least two substances to be mixed inside it; the mixing chamber extends along an operating axis (2a) and comprises an elongating portion (2b) adapted to impart a deforming stretching in the direction of the operating axis along which the mixing chamber itself extends, to a flow of material F disposed inside the mixing chamber, and at least one stratifying portion (2c) connected without a break to the elongating portion and adapted to internally define a multi-layer accumulation of the material flow F coming out of the elongating portion.
(FR)
L'invention concerne un mélangeur comportant une chambre (2) de mélange, des orifices (3) d'accès prévu pour donner accès à la chambre de mélange et un moyen (4) de propulsion agissant sur la chambre de mélange pour déplacer un mélange M ou au moins deux substances appelées à y être mélangées ; la chambre de mélange s'étend le long d'un axe (2a) de fonctionnement et comporte une partie (2b) d'allongement prévue pour appliquer une déformation d'étirement, dans la direction de l'axe de fonctionnement le long duquel s'étend la chambre de mélange proprement dite, à un écoulement F de matière disposé à l'intérieur de la chambre de mélange, et au moins une partie (2c) de stratification reliée sans rupture à la partie d'allongement et prévue pour définir intérieurement une accumulation multicouches de l'écoulement F de matière sortant de la partie d'allongement.
