Electrostatic Spray Dryer
Electrostatic Spray Dryer
Introducing the Future of Spray Dry & Microencapsulation
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.
The PolarDry® Difference
Low Operating Temperature
Our spray dryers utilize electrostatic technology to drive water to the outside of the droplet allowing us to dramatically lower operating temperatures from the traditional ~200 °C to ~80 °C. This lower temperature allows for greater encapsulation efficiency for high-volatile components and reduces heat degradation of molecules/components.
All-In-One Design
PolarDry® all-in-one systems feature small footprints which reduce maintenance and installation costs. They feature a disposable inner liner making for easy clean up and/or changeover. The complete product line shares many similarities simplifying the typical development work to scale up from one machine to the next.
Environmentally Friendly
Our nitrogen inerted systems are SAFE! Process gas is recycled virtually eliminating regulatory issues regarding negligible emissions.
Dust Free
PolarDry machines are virtually dust free. Each negative pressure spray chamber has inflatable seals with alarms if seal pressure is not met. All finish material is collected in a centralized collection system (no cyclones or dust collectors required) and finished material is removed using a sealed conveying systems. Particle separation filters are high efficiency with a dust sensor on the exhaust system and HEPA filters on the inlet and exhaust. The whole spray chamber comes with Wash-In-Place tank cleaning nozzles so that any dust remaining in the vessel can be cleaned prior to opening up the vessel.
Liner
PolarDry’s patented liner system has several benefits key to the operation of the electrostatic spray dryer technology as well as making operation, clean up, and change over simple. The FDA compliant liner is inserted in the spray chamber from the top and covers the vessel walls from top to bottom. This forms a thermal barrier that insulates the vessel walls preventing heat loss to the process room and faster warm-ups. The liner may be washed using tank cleaning nozzles then removed for product change over if required.
Unique Nozzle Design
All polar dry nozzles are designed by Spraying Systems Company, Experts in Spray Technology. Each nozzle is precision machined to high tolerances to assure consistent droplet formation, fully analyzed and supported by the Spraying Systems organization assure a high level of technical support, droplet data and analytical support. The PolarDry nozzles are designed for reliable service, safety, and consistency especially for electrostatic spray drying technology.
Granulating While Drying
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.
