Fluid Bed Dryer GMP Model |
Characteristics and Special Features :
|
Fluid Bed Dryer offers a lucid solution to drying of wet granules, crystalline or coarse materials. It utilizes the principle of passing the hot air at a high velocity through the bed of the material to be dried, thus causing it to fluidize. |
|
|
The blower situated on the exhaust side of the dryer operates on negative pressure principle, which creates the induced draught and sucks in the fresh air into the dryer. A stream of hot filtered air is introduced from the bottom of product container containing the wet material. This container is provided with the air distribution plate and a dutch sieve. The air stream is passed through the bed ofthe material and fluidizes the product particles by creating the turbulence in the product container. Due to fluidization each particle gets surrounded by hot air, which leads to quick & uniform heating and drying. Filter bags provided at the top prevent escaping of particles from the machine. |
|
The different options of heating arrangements are available in FBD viz. Electric/steamffhermic fiuid heating system etc. Electric heaters can raise the air temperature by upto 70° e from ambient temp (i.e. from 30° eto 100° q. Similarly the air temperature can be raised by 60° e to 80° e through steam radiator depending on the steam pressure.
The drying time varies from 30 - 60 minutes subjected to various parameters like physical characteristics of material, initial moisture content and its type (free moisture or water of crystallisation), steam pressure, drying temperature etc. Generally, the drying time for amorphous is longer than crystalline one having same percentage of moisture content.
IMPROVED EFFICIENCY & PRODUCTIVITY
In this unit the stream of hot air at optimum temperature and velocity is allowed to come in contact uniformly with each particle granule ofthe product. Hence, the efficiency of heat transfer is very high resulting in substantial saving in time and energy.
Once a product is established, its optimum cycle time allows repeatability of process.
