The invention concerns a method for encapsulating fine solid particles in the form of microcapsules. Said method is characterised in that it comprises steps which consist in forming a suspension of said particles in a liquid consisting of at least a coating agent in intimate contact with a fluid having a pressure lower than its critical pressure, so as to saturate said suspension, spraying said fluid-saturated suspension through expansion means, and collecting the microcapsules in the gas stream resulting from decompression.
La présente invention concerne un procédé d'encapsulation sous forme de micro- capsules de fines particules solides. Ce procédé est caractérisé en ce qu'il comporte les étapes consistant à constituer une suspension de ces particules au sein d'un liquide constitué au moins d'un agent de revêtement en contact intime avec un fluide à une pression inférieure à sa pression critique, de façon à provoquer la saturation de ladite suspension en ce fluide, pulvériser la suspension ainsi saturée en fluide à travers des moyens de détente, et collecter les microcapsules dans le flux gazeux résultant de la décompression.
