Abstract

Procédé et appareil de séparation en continu de cristaux et de liqueur-mère présents dans un mélange de ces constituants. L'appareil est conçu pour l'élimination par lessivage à contre-courant en continu de matière solide en particules, il comporte des moyens de détection pour indiquer la concentration de substances indésirables dans le liquide adhérant aux cristaux séparés, et des moyens pour régler un ou plusieurs paramètres du processus en réaction à des signaux provenant des moyens de détection. Application : notamment aux extraits de café et aux jus de fruit
