Title: Appareil et procede d'enrobage d'une particule solide
Inventor: SCHURR GEORGE ALAN
IPC: B01J2/00
Filed: 1996-08-21
Abstract: La présente invention se rapporte à un procédé et à un appareil servant à l'enrobage d'une particule solide. Ledit procédé consiste à injecter une quantité mesurée d'une composition liquide comportant une matière d'enrobage, ladite composition liquide étant soit une solution, soit une boue, soit une matière fondue, à l'intérieur d'un dispositif d'étranglement du flux et à injecter un courant gazeux à travers le dispositif d'étranglement simultanément à l'injection de la quantité mesurée de composition liquide de façon à créer une zone de turbulence à la sortie du dispositif d'étranglement du flux, ce qui permet d'atomiser la composition liquide. On chauffe le courant gazeux avant de l'injecter à travers le dispositif d'étranglement du flux. On ajoute une particule solide à la zone de turbulence simultanément à l'injection de la quantité mesurée de composition liquide et à l'injection de gaz chauffé de façon à mélanger la particule solide à la composition liquide atomisée. Le mélange effectué au niveau de la zone de turbulence permet d'enrober la particule solide de la matière d'enrobage. Si la composition liquide est une matière fondue, alors le solide est enrobé de cette matière fondue. Si la composition liquide est une solution ou une boue, la particule solide est enrobée de la matière solide dissoute ou non dissoute de la composition solide. Cet appareil et le procédé associé permettent un temps de séjour bref, c'est à dire inférieur à 250 millisecondes, dans la zone de turbulence, ce qui permet de réduire le temps et donc le coût d'enrobage des particules. En outre, ce procédé et cet appareil offrent un mécanisme d'enrobage de particules de très petites tailles, pulvérulentes ou en grains qui permet d'obtenir une forte production de particules non agglomérées, entièrement enrobées.
