FREQUENTLY ASKED QUESTIONS (FAQs)
- What is the Fluid Air PolarDry Model 050 electrostatic spray dryer used for?
The Fluid Air PolarDry Model 050 is an electrostatic spray drying system designed to convert compatible liquid formulations into dry powders. Potential applications include pharmaceutical ingredient processing, nutraceutical powder production, food ingredient drying, specialty chemical manufacturing and microencapsulation of selected formulations.
- What is the maximum evaporation capacity of the Fluid Air PolarDry 050?
The machine has a maximum rated evaporation capacity of 50 kg/hr. This represents the stated evaporation capacity rather than the amount of finished dry powder produced per hour. Actual powder output depends on feed solids concentration, moisture content, product characteristics and operating conditions.
- What is electrostatic spray drying?
Electrostatic spray drying uses electrically influenced atomization to form droplets from a liquid feed, followed by drying under controlled gas and temperature conditions. The technology is designed to support specialized powder formation and may provide processing advantages for certain formulations compared with conventional spray drying methods.
- How does electrostatic spray drying differ from conventional spray drying?
Conventional spray drying typically relies on atomization and heated gas to evaporate liquid from droplets. Electrostatic spray drying introduces electrical effects into the atomization process, potentially influencing droplet and particle behavior. Depending on the formulation and process design, this may support specialized powder properties or different drying conditions. Actual performance must be established for each product.
