FBD Fluid Bed Dryer Machine

The FBD Fluid Bed Dryers is our latestest design Powder Dryer Equipment. It is a Fluid Bed Dryer. The Powder Drying Machine use nitrogen to dry material, not air. Nitrogen is more save compare with air. And this machine has condensation device. After condensation, the solvent is collected by the collection tank, in this way, no solvent discharge to air, no pollution. The recoved solvent can be used again. 

Principle:

The Fluid Bed Drying Machine is composed of the main machine, air handing system, heating system, control system, etc. When it works, the materials enter the silo of the boiling dryer. Set the procedures and parameters according to process requirements and the machine will start working. After filtered by the air handing system and heated by the heating system, the air enters the main machine. After the materials are fluidified and dried by hot air, the moisture is evaporated rapidly and the materials are dried instantly. After the operations are completed according to the set procedures and parameters, the material silo is pushed out and assembled onto the YTZ series fixed lifting material Transferring Machine for lifting discharging. or is pumped to a high position by the vacuum charging machine for granule sizing by the granule sizing machine, so as to effectively control dust pollution and cross contamination. 

Drying time:

The drying time depends on various factors such as physical properties of material, moisture content, type of moisture ( free or inherent of water or crystallization) drying temperature etc. For example, the crystalline product can be dried faster than amorphous product containing same percentage of moisture at same temperature. Pharmaceutical granules & powder having approximately 20% to 25% moisture can be easily dried. Fluid bed dryers are normally supplied either with electric heating or with steam heating. However hot water/ hot oil circulation system can also be installed.
