Fluid Bed Dryers

Fluid Bed Dryers

AT-FBD Fluid Bed Dryer is used for fast drying of wet granules, crystalline or coarse materials in
pharmaceuticals, chemicals, food and dairy Industries.


The machine is made compact, versatile and enclosed in stainless steel elegantly finished body, having SS made
Bottom Inlet Chamber, Product Container, Loading Trolley with PU Castor Wheels, 5 micron PC Satin cloth
Filter Bag with Suitable clamping system and Inflatable Sealing, Air Supply Unit with heating arrangement and
micro filters, Exhaust blower with interconnecting duct and Electric & Pneumatic Control system. The specially
designed Exhaust blower operates on negative pressure principle, which creates the induced draught and sucks in
the fresh air into the dryer which got heated while passing through the air supply unit. This hot filtered air is
introduced from the bottom of product container containing wet 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 uniform heating and drying without affecting the physical and chemical properties of the products
and also reduced drying time. Filter bags provided at the top prevent escaping of particles from the machine.
