Abstract

Procédé et dispositif servant à préparer une matrice encapsulée contenant une charge de produit. On éjecte par pulvérisation un additif de matrice de produit solide à l'état coulant. On encapsule cet additif de matrice dans son état coulant au moyen d'un agent d'encapsulation de matrice. L'additif encapsulé se solidifie dans son état coulant, ce qui permet d'obtenir la matrice de produit.
