Laboratory Closed Loop Organic Solvent Spray Dryer with Nitrogen Circulation
Loop sequence Atomized feed contacts heated nitrogen. Powder is separated and collected. The process gas passes through filtration and condensation;.
Compact nitrogen circulation spray drying for solvent based and oxidation sensitive laboratory samples
| Built for controlled solvent processing AV-OSSD6000 is a compact closed loop spray dryer for laboratory development with organic-solvent-bearing, toxic, harmful or oxidation-sensitive feeds. Nitrogen replaces process air and circulates through drying, filtration and condensation sections. Oxygen and pressure monitoring support controlled operation, while the condenser captures solvent from the circulating gas before reuse. Recommended use Best for formulation screening, small-batch material development and solvent-based feasibility trials. 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.
