Fluid Bed Dryer

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. The fresh air is heat by means of electrical heaters or steam or thermic fluid heaters. This hot air stream expands the bed of material at certain velocity & creating turbulence in the product. The phenomenon is known as fluidization and offer conditions which are almost ideal for drying. Fluidization produces full agitation of solid particles and since each particle 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.

The air used for drying is filtered and gets heated in the Air Handling unit (AHU), which was having Prefilter (EU 4 Grade, 10 microns), Fine filters (EU 5 Grade, 5 microns), HEPA Filters (EU 13 Grade, 0.3 microns) and steam coil.

The hot air from the AHU is distributed evenly inside the driers. And moisture absorbed air will released to the atmosphere after proper filtration.
