1. A spray-drying apparatus, comprising:
a gas inlet manifold comprising an inlet conduit that defines a gas passageway and a spacing member that extends laterally from the gas passageway of the gas inlet manifold;
a single-use drying chamber having a first opening defined by a first surface portion at an inlet end, a second opening defined by a second surface portion at an outlet end, and a third surface portion extending longitudinally from the inlet end to the outlet end;
a spray liquid inlet pipe having a proximal end and a distal end, the distal end of the spray liquid inlet pipe being coaxial with the inlet conduit; and
an atomizer at the distal end of the spray liquid inlet pipe, the atomizer extending past an outlet end of the inlet conduit,
wherein the first surface portion is coupled to the spacing member at a location that is spaced apart from the gas passageway by a distance greater than 50% of a radius of the gas passageway to establish a gap between the first surface portion and an outside surface of the inlet conduit, and
wherein the single-use drying chamber has an inner surface that is formed of a polymeric material.
