Fluid Bed Dryer In Pharmaceutical Industry

Generally high energy input is required during this process to provide the latent heat of water.

Fluid bed dryer in pharmaceutical industry. For more than 50 years gea has supplied fluid bed processors for blending granulating drying pelletizing and coating for the pharmaceutical industry. Adding an aqueous or alcoholic granulation medium compresses the mixture of dry powder particles. Fluidized beds are extensively used in the pharmaceutical and other chemical industries either as a batch or continuous process for drying moist powders and granular solids. If you re not familiar with this process it simply involves agglomerating small powder particles together by using a granulating liquid solution.

So far a number fluidized bed drying studies have established that it is the most reliable and dependable technique in the pharmaceutical industry. Fluidized bed dryer fbd is well known and widely used equipment in granulation area of pharmaceutical manufacturing. Fluid bed dryers provide the best solution for drying many products but especially products within the pharmaceutical industry. Direct dryers convectively heat a product through direct contact with heated air gas or a combusted gas product.

Dryers can be broken up into two main types. For a long time fluidized bed solutions. Its main role includes drying granules produced by the wet granulation process. A fluid bed dryer also named fluidized bed dryer is an assembly of systems for drying material in the pharmaceutical industry.

There are various types of dryer used in pharmaceutical industries. 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. This is due to good mixing of solids and intensive heat and mass transfer between the solid and hot gas phases in the system. This includes small capacity systems designed for r d as well as industrial size plants for batch production of pharmaceutical compounds under cgmp conditions.

In fbd there is direct contact between particles and any type of inert air gas. This is due to the many advantages that it offers over the conventional drying techniques. The fluid contains a volatile solvent which can be removed by drying. Implying by using fbd equipment you can achieve a suitable moisture content in either powders or granules.

Fluid bed dryers are most widely used for drying pharmaceutical powders and granulation. Fluidized bed systems have been used in the pharmaceutical industry for many decades. The fluid bed drying operates under the principle of direct drying where direct contact between a heated gas air and the product occur to effect heat and mass transfer. Fluidized bed granulator fluidized bed dryer bfs.

Fluid bed dryer plays an integral role in the pharmaceutical industry. Indirect dryers conductively heat a product through contact with a heated wall.
