Beschreibung
Zusammenfassung:	A process for continuously producing coated particles and in particular, particles in which the coating is uniform, continuous and of minimal thickness is described, together with an apparatus for conducting the coating process in which a plurality of coating cells connected in series are provided wherein the particles are pneumatically conveyed during the coating application and in which controlled recirculation of particles occurs within each cell and a controlled spray is applied to the particles in order to produce a substantially uniform distribution of coating. Procédé de production en continu de particules enrobées et en particulier de particules dont l'enrobage est uniforme, continu et d'une épaisseur minimale, et appareil de pilotage du processus d'enrobage comportant plusieurs cellules d'enrobage montées en série à travers lesquelles les particules sont transportées pneumatiquement pendant que s'opère l'enrobage. Dans lesdites cellules les particules subissent une recirculation et une pulvérisation contrôlées donnant une distribution sensiblement uniforme de l'enrobage.
