Pharmaceutical Spray Drying Services

Spray drying for pharmaceutical applications is a preferred method for creating powders from liquid formulations. These liquids are sprayed through a nozzle to create a controlled droplet size. The sprayed droplets are exposed to short bursts of hot air, evaporating them until the drugs are converted into a fine powder.

With state-of-the-art equipment and a wealth of experience, CritiTech Particle Engineering Solutions is a premier spray drying company to help your company achieve optimal results. Our experience with spray drying in the pharmaceutical industry means we can help you deliver the ideal form factor for your drug.
