Nitrogen Closed Cycle Spray Dryer-Organic Solvent Spray Dryer-Anvore Scientific-Lab & Industrial Process Equipment

Nitrogen Closed Cycle Spray Dryer

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

ModelAV-OSSD2L

BrandANVORE

Higher-throughput two-fluid spray drying with dual condensers and automatic filter cleaning

Built for controlled solvent processing AV- OSSD2L expands laboratory closed-cycle processing with a 2 L product collection vessel, dual condensers and automatic filter cleaning. It is intended for solvent-bearing or oxidation-sensitive feeds that require nitrogen circulation instead of open-air drying. Oxygen-based feed control, pressure monitoring and adjustable airflow help operators establish a repeatable process window. Recommended use Best for laboratory scale-up, formulation optimization and small pilot batches requiring improved powder recovery. 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.
