Principle of operationfluid bed dryers

• Direct contact between material and process air.

• Fluidised state of product by upward moving flow of gas.

• Mechanical movement of dryer drive improves fluidisation.

• Material is dried and subsequently cooled in one machine.

Expanded hood design

Expanded hood design

Reduces the velocity of the exhaust air in the hood.

Ductwork lasts much longer.

Particles will drop back in the bed instead of going to the air filter. Lower loading on the baghouse.
