Abstract

In a compact combined spray drying and after-treatment apparatus having internal gas filters and an internal fluidized bed in the drying chamber and a fluidized bed in the after-treatment zone, pipe means are used for conducting a stream of particle-loaded gas formed in the after-treatment zone to suitable locations in the drying chamber without disturbing the normal operation of the drying chamber and the fluidized bed therein.
