Zusammenfassung:	The present disclosure relates to a method, including providing one or more lyophilised microspheres in a mixing vessel at a first temperature and generating a fluidized bed of the one or more lyophilised microspheres in the mixing vessel, under conditions effective to encapsulate the one or more lyophilised microspheres with a coating formulation. In an example, the fluidized bed has a fluidization rate of between about 1 cubic meters per hour (m3/h) and about 30 m3/h. In another example, the fluidized bed has an environmental humidity of between about 10% and about 20%. In still another example, the coating formulation is applied at a spray rate of between about 1.5 grams per minute (g/min) and about 10 g/min. In yet another example, the coating formulation is applied at an atomizing rate of between about 0.5 bar and about 1.5 bar. In a further example, the fluidized bed is in a Wurster configuration, a top spray configuration, or a combination thereof. The present disclosure also relates to a system, including one or more lyophilised microspheres, a mixing vessel configured for holding the one or more lyophilised microspheres, a mixer for generating a fluidized bed of the one or more lyophilised microspheres in the mixing vessel at a location, and at least one spray nozzle configured to introduce a shell formulation into the mixing vessel at the location.
