The patented PolarDry^® Electrostatic Spray Dryer utilizes revolutionary electrostatic technology which drives water to the shell and active to the core, lowering the evaporation temperature and eliminating active ingredient loss, degradation, or denaturalization. Harnessing the electrostatic effect, the dispersed active driven into the core is microencapsulated, virtually eliminating surface active, resulting in stunning encapsulation efficiency.

By controlling the electrostatic charge applied to the feed on an intermittent basis, PolarDry^® Technology gives you the means to agglomerate particulates as they are being dried. This patented feature, PWM (Pulse Width Modulation) precludes the need for expensive secondary agglomeration operations.

By controlling the voltage applied to the spray droplet as it is being atomized, some particles form an outer shell readily while others develop their shell gradually resulting in a wet or tacky particle. As these two types of particles colloid, they bond forming an agglomerated particle. This results in a finished product with larger particles and fewer fines which flow freely.

As the FDA and other worldwide regulatory agencies are pushing continuous process in the production of pharmaceuticals, the PolarDry^® process stands ready to meet the requirements. PolarDry^® machines incorporate a unique patented collection/particle separation plenum that can be easily configured for batch or continuous processing by configuring the outlet as shown above.

Flexibility is a key consideration when developing your process. PolarDry^® machines are designed to ensure:

• Quick Set Up from one run to the next by integrating in the design a disposable inner chamber liner that can be changed in a matter of minutes.
• Patent pending cartridge filter configuration that allows easy turnaround from one run to the next. The reverse pulsing feature ensures that drying gas flow remains steady.
• Portability so machines can be easily transferred from one suite to another:
• Model 001 and Model 004 are on wheels and fully contained, only requiring electricity, a Nitrogen intake, and an outside chiller (Model 004 only) to operate.
• Model 032 only requires electricity, a Nitrogen intake, and an outside chiller to operate.

• Nitrogen Inerting/Explosion Protection
• Redundant oxygen monitor prevents operation if oxygen level is too high
• Rated lid safety lock & monitored inflatable seals prevent the operator from opening the vessel lid if oxygen level isn’t safe (Model 004 and above)
• Heater over temperature protection
• Emergency stop buttons and monitoring with safety reset
• Voltage generator resets if amperage exceeds 8 mA, protecting the operator
• Area oxygen monitoring
