MEPL- FLUID BED DRYER:

is most suitable for drying granular, crystalline, coarse or similar materials in pharmaceuticals, fine chemicals, dyes, food & allied industries. Advantages of short drying time, uniform drying, rapid exchange of granules, low drying temperature.

OPERATION:
The wet material is introduced into the dryer as batch of material in product container which is provided with air distribution plate and dutch weave. The blower creates induced draft and fresh air is sucked into the unit. After filtration, clean air passes through heating elements. This hot air then passes through the product container creating turbulence in the product and hence the product moves up & down in the product container. Due to this the heat transfer is quick and the product is dried fast appreciable loss of heat. Filter bags prevent particles escaping from dryer.

HEATING:
Fluid bed dryers can be supplied in electric heating, steam heating or hot water / oil circulation system. Generally dryers bigger than MFD-60 are incorporated with Steam heating system, as steam heating is more economical.

SAFETY:
FBD is provided with explosion flap and pressure relief valve, in case of excess pressure the pressure is relived through the explosion vent located on the rear / top of the unit.

DRYING TIME:
The drying time depends upon various factors such as physical properties of material, moisture (free moisture or water of crystallization), drying temperature etc,. Generally pharmaceutical granules or crystals containing free moisture of about 20 to 25% can be easily dried in about 30 to 40 minutes at a temperature of about 80C.
