Function and Principle of Operation

Based on a platform of innovative and advanced application technologies, the Triple-A Spray Dryer combines a new spray dryer design with an integrated fluid bed and an optional external fluid bed, providing our customers with total control over product quality and process efficiency.

Triple-A Spray Dryers consist of five main components, all of which can be customized to meet individual requirements:

• Air distribution and nozzle atomization system
• Spray dryer
• Exhaust and fines recirculation system
• Second-stage integrated fluid bed
• Third-stage external fluid bed

The air distribution system delivers a constant airflow at a controlled temperature and volume into the spray dryer, integrated fluid bed, and optional external fluid bed. The nozzle atomization system ensures precise control over air distribution within the drying chamber, as well as powder particle and agglomerate sizes.

The spray dryer features a chamber design that ensures dust-free drying of a wide range of products, from low-fat to hygroscopic and "sticky" substances, leaving minimal product residue in the chamber. This design allows for significantly longer production times between CIP cycles.

The recirculation system utilizes cyclones, bag filters or a combination of both to recycle fines back into the spray dryer chamber, integrated fluid bed or external fluid bed. An integrated second-stage fluid bed is used for final, low-impact drying and cooling. The configuration is customized based on required capacity, residence time, temperature constraints, etc. An external fluid bed, including vibratory options, can be incorporated and connected to the integrated fluid bed outlet for additional drying and cooling.
