ABSTRACT:
A device for preparing a spray-dried product includes a drying chamber with a distribution element placed therein for atomizing liquid to be spray-dried, an element for supplying drying gas, an element supplying a stream of solid particles to a stream of droplets atomized from the distribution element, and one or more fluidized beds, each having at least one bottom plate with openings which has gas supply structure opening out at the underside thereof. These fluidized beds are placed connected to each other inside the drying chamber, opposite the distribution element, the above in such a way that the combined streams of droplets from the distribution element and solid particles fall essentially into the first bed, and conveyance of material from the first bed to the second bed can take place.
