Closed Loop Centrifugal Spray Dryer

Loop sequence Atomized feed contacts heated nitrogen. Powder is separated and collected. The process gas passes through filtration and condensation;.

ModelAV-OSSD5L

BrandANVORE

Pilot closed-cycle centrifugal atomization with dual-stage heating, condensation and vibration

Built for controlled solvent processing AV-OSSD5L is a pilot closed loop centrifugal spray dryer for solvent-bearing, hazardous or oxidation-sensitive materials. A nitrogen circuit carries droplets through the drying chamber, then passes through powder recovery and two condensation stages before recirculation. Centrifugal atomization, 0–300 m³/h airflow and a 5,000 mL/h maximum stated feed rate support larger process-development campaigns. Recommended use Best for pilot production trials, centrifugal-atomization studies and scale-up of solvent-based materials. Process note Final solvent compatibility and operating conditions should be confirmed by a process-risk assessment.

Six Key Advantages

PRINCIPLE AND TECHNICAL DATA

Loop sequence Atomized feed contacts heated nitrogen. Powder is separated and collected. The process gas passes through filtration and condensation; recovered solvent is collected, and dry nitrogen returns through the blower and heater.
