Fluid Bed Drier (FBD)
Product Description

Fluid Bed Dryer:

 

Applications

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. A model with complete automation and PLC, automatic bag shaking and with MIMIC is also offered
 
The drying time depends on various factors such as physical properties of material, moisture content, type of moisture (free or inherent or water of crystallization), drying temperature etc. For example, the crystalline product can be dried faster than amorphous product containing same percentage of moisture at same temperature.
Salient Features
Machine and the trolley are made in SS-316 construction. The lifting jack is housed in the inlet lower chamber (part of the main shell). It is of Stainless Steel 316 quality and is lined with neoprene grade rubber of suitable hardness for sealing with the product container.
The lifting jack is fitted with a pneumatic lifting device, which consists of 2 numbers pneumatic cylinders along with control valves, pressure regulating device and air filter. Air pressure requirement is 4 kg/cm2.
The expansion chamber has a guide for positioning the product container.
The filter bag chamber is made from Stainless Steel sheets of 316 quality. The filter bag can be de-dusted manually or pneumatically.
The air inside is circulated by the blower. It has an impeller with a backward curve type blade and the construction of which is 304. The impeller has a S.S. casting and is driven by Flame Proof or Non Flame Proof Motor.
The dryer is Electrical/Steam Heated as desired. Heaters are of S.S. finned tubes tested to 6 kg/cm2 pressure.
