fluid bed dryer

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 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 Dutch sieve. The air stream is passed through the bed of the 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.

Mode of Heating

The different option of heating arrangement are available in FBD viz. Electric/Stream/Thermic fluid heating system etc. Air temperature can be raised up to 90*C.

The drying time varies depending upon various parameters like physical characteristics of material, initial moisture content, drying temperature and ambient conditions.

Improved Efficiency & Productivity

The stream of hot air at optimum temperature and velocity is allowed to come in contact uniformly with each particle of the product, resulting in efficient heat transfer and substantial time & energy.

Once the product is established through validation process defining optimum parameters in product recipe ensures repeatability of process.

Our PLC based equipment’s can store several such recipes for operators to follow.
