Fluid Bed Dryers

Fluidized bed dryer (FBD) is well known and widely used equipment in granulation area of pharmaceutical manufacturing. It is used in the granulation process for drying the material to get desired moisture content in the tablet formulation granules required for perfect compression of tablets. In fluidization process, hot air is introduced at high pressure through a perforated bed of moist solid particulate. The wet solids are lifted from the bottom and suspended in a stream of air (fluidized state). Heat transfer is accomplished by direct contact between the wet solid and hot gases. The vaporized liquid is carried away by the drying gasses. The Filter bag prevents particle escaping from the dryer. * Fluid bed drying is most widely used technique for drying pharmaceutical powders, granules and slurries * Fluid Bed Dryer has a high drying rate, therefore, the material gets dried very quickly. Because of this property, this machine proves very useful in giving out high output. * Fluid Bed Dryer has been put in use to create synthetic resins. This machine can also be used in food, fertilizers, ceramics, Agrochemicals, etc. * Online charging from RMG into FBD using vacuum. Inlet feed port with SS gas tight pneumatic actuated valve * Sampling provision of inline analysis of granulation profile such as moisture content and particle size analysis * Fluidization produces full agitation of solid particles and each particle gets surrounded by hot air, heat transfer is extremely high and uniform * The material is left for some time in the dryer for reaching ambient temperature * The end product is free flowing * View port in filter housing and in expansion area of machine tower and product container * Dryer has low maintenance cost subsequently, reduces downtime * Fluidized bed dryer requires less time to complete drying i.e 20 to 40 min * Hot spots are not observed in the dryer, because of its excellent mixing and drying capacities
