Fluid Bed Dryer:
Shree Krishna Engineers designed and manufactured fluid bed dryers to dry powder particles, where the residual moisture content is higher than what is wanted in the final powder. Fluid bed drying offers important advantages over other methods of drying particulate materials. Particle fluidization gives easy material transport, high rates of heat exchange at high thermal efficiency while preventing overheating of individual particles.
Technical literature for valued Customer Understanding:
FLUID BED DRYER:-
The principle is based on the phenomenon that solids having a well defined particle size distribution behave as liquid when fluidized by air. By preheating the air, the residual moisture can be reduced.
Fluid bed processing involves drying, agglomeration, granulation, and cooling of particulate materials. It is ideal for a wide range of both heat sensitive and non-heat sensitive products.
In fluid bed drying heat is supplied by air/gas through the product layer thereby removing moisture contents in the powder material. Hot drying air is distributed through specially designed perforated plates, on which the powder particles/agglomerates are resting.
The velocity of the drying air makes the powder `luidize`, i.e. the particles get airborne; however, to the extent that only the finest/smallest particles leave the fluid bed with the air, while the bigger particles/agglomerates are conveyed/transported with the upward and forward directed flow of air (due to the perforation technique of the plate) into the subsequent section.
Fluid bed drying is suited for powders, granules, agglomerates and pellets with an average particle size between 50 microns and 5 mm.FBD has an air distributor plate welded directly to the fluid bed housing. It is widely accepted in food and dairy industries because of its high sanitary standards and automatic cleaning systems.
