"Precious" Fluid Bed Dryer. |
Operation.:
Fluid bed dryer is designed to introduce the hot air stream at the
base of the product container which is filled with the material.
Induced draught is created by means of blower and fresh air is sucked
in to the unit. This hot air system expands the bed of material
at certain velocity & creating turbulence in the product. The
phenomenon is know as fluidization and offer conditions which are
almost ideal for drying. Fluidization produces full agitation of
solid particles and since each particles gets surrounded by hot
air, heat transfer is extremely high and uniform. The product is
dried fast without appreciable loss of heat. Filter bags prevent
particles escaping from the dryer. |
Suitability.:
The conventional drying method of drying products in tray dryer is
rather inadequate and trouble some. They occupy large floor space,
have very high drying times, are labour intensive and offer uneven
drying. On contrast fluid Bed Dryer occupy comparatively lesser floor
space, are very easy to operate and can dry material in least time
as compared to tray dryer.
In fluid Bed Dryer, temperature distribution through out the product
is uniform and the heat transfer rate is very high. Due to the reduce
drying time high production rates are achieved.
As the product is in close contact with drying air at low temperature
and also for short duration, the physical and chemical properties
of the properties of the products are generally not effected and
therefore the dryer can effectively be used for heat sensitive products.
Due to the continuous movements of product during drying lump formation,
case hardening etc.. are minimized.
The fluid Bed Dryer are most suitable for drying granular crystalline,
coarse or similar material in pharmaceuticals, fine chemicals, dyes,
food and allied products.
The fluid Bed dryer is not suitable for drying liquid or pasty
materials. |
