In a spray dryer, the milk is pumped to a nozzle or rotary valve disc atomizer which sprays the feed in fine droplets into a drying chamber. The droplets are subject to a stream of hot air flowing either counter-currently or cocurrently in relation to the falling droplets. Thereby, the droplets of milk are dried so the dry matter remains as ...
