Abstract
A process for continuously producing coated particles, and in particular, particles in which the coating is uniform, contiguous 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.
