Spray Drying

In 2014, our customers asked us to build a major new aqueous-based spray drying operation based in the US. This major investment is a state-of-art, high volume spray drying operation with a fully automated CIP (Clean-In-Place) system. The spray dryer is validated to comply with US FDA 21 CFR 210.211 & EU Drug Certification standards.

Advantages of Spray Drying:

Choose between wide variety of polymers and adjuvants

Processing is performed at relatively low temperatures

Improves solubility and bioavailability of API’s

Works well with temperature sensitive compounds

Ability to control critical powder physical characteristics, including:

Taste masking

Improved mouthfeel

Better dissolution/disintegration

Improved particle size consistency

Our R&D Group has the small scale equipment to quickly assess custom product or material requests. The minimum batch amount required for R&D purposes is approximately 5 kg.  This amount is needed to allow the PDH R&D team to compile data on the proposed material, including the characterization of slurry/dispersion preparation methods, as well as the characterization of particle size and morphology.
