Spray-drying/spray-congealing

Spray Drying is an instant and continuous solvent evaporation process of a liquid feed, atomised in a heated gas, generating a final dried solidified particle.

The heated drying gas moves in co-flow with the atomised feed in the process chamber where the gas transfers its heat energy to the droplets and absorbs the solvent from the droplets. The humidified cooled gas transports the particle to a cyclone, separating the final particles from the gas.

By Spray Drying particles can be engineered to a specific size, shape and function by formulating the liquid feed and designing the process.

Applications: Solubility enhancement, Encapsulation, Taste masking, Modified Release, Inhalation, Flow-ability improvement, Physico-chemical Stabilisation
