The fluid bed dryer machine is made to use in the Pharmaceutical, chemical and food industry for drying and cooling of granules, crystalline, coarse and similar materials. The use of fluid bed dryer is to cool and dry the particles by exposing them to a stream of hot dry air. The machine can be also used for post drying of spray granules or particles with a low moisture content. The FBD has replaced the old tray drying machines. The machine is manufactured in a single piece with integrated expansion chamber made up of stainless steel.

Process of Drying

The moist particles or granules are fed into a shaking perforated sheet. A stream of fluid bed drying air is passed through the perforated sheet. The hot air comes in contact with the particles on the sheet and they are lifted slightly. The shaking of the sheet leads to transportation of the materials along the length of the dryer. The moisture is carried away by hot air thereby drying the solid material. The fine particles are agglomerated to large granules. The temperature and volume of the air is maintained throughout the process. After drying the granules are passed through a cooling air zone to cool them to the required temperature.
