Fluid Air’s PolarDry technology utilizes new electrostatic spray drying. The low-temperature spray drying provides the means to make new drug formulation ideas a reality. Applications include API production where high temperature is a limiting factor and new avenues for drug delivery where perfect encapsulation is a must.

The selective agglomeration creates particles that can be produced at ambient to 80°C inlet conditions. This is possible since the electrostatic effect drives highly polarizable water/solvent to the outer shell of the particle making it easy to dry the particle. Low temperatures eliminate ingredient loss, degradation, or denaturalization. Less polarized active and excipients are driven to the core, which microencapsulates the active and virtually eliminates surface active, resulting in high encapsulation efficiency.

PolarDry technology advantages include: superior morphology, higher bulk density, longer shelf life, non-reactive processing, minimal emissions, and low energy consumption.
