Title
(EN) DRIPPING MECHANISM TO REDUCE PARTICLE SIZE IN MICROENCAPSULATION METHODS
(FR) MÉCANISME D'ÉGOUTTEMENT POUR RÉDUIRE LA TAILLE DES PARTICULES DANS DES PROCÉDÉS DE MICROENCAPSULATION
Abstract
(EN)
The invention relates to a dripping mechanism (10), developed for use in microencapsulation methods, provides at least one injection tip (12) which transfers the core and wall material matrix into the solidifying solution in the form of droplets, to reduce the particle sizes and to provide homogeneous size distribution, a vibration wheel (13) providing the frequency- controlled vibration of aforementioned injection tip (12), and a drive element (15) to rotate aforementioned vibration wheel (13).
(FR)
L'invention concerne un mécanisme d'égouttement (10), développé pour être utilisé dans des procédés de microencapsulation, comprenant au moins une pointe d'injection (12) qui transfère la matrice de matériau de noyau et de paroi dans la solution de solidification sous la forme de gouttelettes, pour réduire les tailles de particules et pour fournir une distribution de taille homogène, une roue de vibration (13) fournissant la vibration commandée en fréquence de ladite pointe d'injection (12), et un élément d'entraînement (15) pour faire tourner la roue de vibration susmentionnée(13).
