Abstract

See full text

The present invention relates to an apparatus for coating carrier particles with guest particles. The apparatus comprises a cylindrical processing vessel rotatable about its axis and having solid walls defining a chamber for receiving the particles, and a hollow shaft extending within the chamber at least partly along the axis of the cylindrical processing vessel, the hollow shaft defining a gas flow path connected to a gas inlet. The hollow shaft comprises one or more axially-extending slots or one or more axially-extending rows of apertures allowing fluid communication between the gas flow path and the chamber. The apparatus may be used in a process for coating carrier particles with guest particles, the process comprising: adding the particles to the chamber defined by the cylindrical processing vessel; rotating the cylindrical processing vessel about its axis; and flowing gas from the gas inlet along the gas flow path in the hollow shaft and into the chamber through the one or more axially-extending slots or one or more axially-extending rows of apertures.
