Abstract

A spray-drying apparatus includes a drying chamber that has a first end, a second end, and at least one side wall extending between the first and second ends to define an interior of the drying chamber having a center axis. A nozzle can be positioned at the first end of the drying chamber and be configured to atomize liquid and spray the atomized liquid into the interior of the drying chamber at a maximum spray pattern angle relative to the center axis. A ratio of the length between the first end and second end to a maximum width between opposing internal surfaces of the interior of the drying chamber can be at least 5 to 1.
