Fluid Bed Dryer manufacturer & exporter from India
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 heated by means of electrical heaters or steam or thermic fluid heaters. This hot air stream expands the bed of material at certain velocity & reating turbulance in the product. The phenomenon is known as fluidisation and offer conditions which are almost ideal for drying. Fluidisation 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 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 & 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.
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 liquids or pasty materials
