FREUND GRANUREX (GXR) Powder Layering 2024

Finely divided/Micronized API and/or micronized polymer and/or micronized excipient is loaded in to a precision powder feeder. Core particles from 100 to 2000+ microns are loaded on to a conical rotor. A small amount of binder, plasticizer or liquid solvent is atomized and sprayed on to the core particles while the dry micronized powders are fed in to the cores via the precision powder feeder. Rotor energy and the precise balance of micronized powder and liquid addition results in very fast coatings of active, polymer or combinations that would take hours or days if applied conventionally from solution. Product movement on the rotor ensures very high uniformity.
