=='''Applications'''== | |||
The | The Fluidized Bed Dryers or [[Fluid Bed Dryers]] (FBD) are primarily used in almost all chemical, pharmaceutical, food, dyestuff and other process industries to dry materials by fluidization with hot and / or dehumidified air, which creates a turbulence in the wet product (not totally liquid) while flowing through it. | ||
=='''Working Principle'''== | |||
The atmospheric air is sucked in the dryer through 5/10 micron filter by efficient dynamically balanced fan driven by an electric motor. The clean air then passes over the electric heaters / steam or radiator provided with controller. The hot air passes through the product and fluidization dries the product. Dryer is provided with dehumidifier (Chilled water system) at the inlet so as to dry the product at low temperature under fluidized condition. The blower speed is controlled by AC frequency drive so as to control the fluidization avoiding choking of the filter bag. A raking system is provided to avoid lump formation in the container to achieve uniform fluidization and uniform drying. | The atmospheric air is sucked in the dryer through 5/10 micron filter by efficient dynamically balanced fan driven by an electric motor.

* Machine and the trolley are scientifically constructed. The lifting jack is housed in the inlet lower chamber (part of the main shell). It is of Stainless Steel and is lined with neoprene grade rubber of suitable hardness for sealing with the product container. | * Machine and the trolley are scientifically constructed.
