Based on a platform of innovative and advanced applications technologies, the Triple-A庐 spray dryer combines a new spray dryer design with an integrated fluid bed and an optional external fluid bed to give our customers total control over product quality and process economy.

Function and Principle of Operation
The Triple-A庐 spray聽dryer comprises five main components, all of which can be customized to individual requirements:

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

The air distribution systems send constant air flow at controlled temperature and volume into the spray dryer, integrated fluid bed, and optional external fluid bed. The nozzle atomization system provides total control over air distribution within the drying chamber as well as powder particles and agglomerate sizes.

The spray dryer features a chamber design ensuring dustless drying of a wide range of products from low-fat to hygroscopic and "sticky", leaving a minimum of product residue in the chamber. This ensures significantly longer production time between CIP.

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