Fluid bed technology in the pharmaceutical industry

Fluid bed technology is a thermal and mechanical process technology for the production of powders and granules. It is based on the generation of a fluid bed or fluidized bed, which is created by a flow of liquid or vapor medium. This separates different components of the fluids and reduces the moisture content in the raw materials, such as powders and granules.

The option to realize several processes in only one system makes the fluid bed technology so attractive: It is possible to dry, coat and granulate solid particles uniformly. Due to the optimized movement in the fluid bed / fluidized bed, the products are treated homogeneously. The technology is correspondingly productive, environmentally friendly and leads to high-quality results.

Further advantages are the flexible integration into the production, combined with a very high process stability, and the introduction of active ingredients during the process, for a very efficient absorption of active ingredients.

In addition to the pharmaceutical industry, fluid bed technology is also used in biotechnology, agriculture, the chemical industry, the food industry and in nutritional supplement production.



Advantages of fluid bed technology

Maximum efficiency: Fluid bed technology guarantees fast and productive processes, resulting in a very good cost-benefit ratio.
High process control and quality: The fluid bed technology allows to precisely control the flow and reaction conditions as well as the moisture and the granule size, resulting in a very good quality.
High productivity: Fluid bed / fluidized bed technology allows high purity granules or pellets to be produced in large quantities.
Scale ability: Fluid bed technology is easily scalable and can be adapted for different laboratory applications as well as for industrial production.
Safe production through established processes: Fluid bed / fluidized bed technology guarantees high process stability and process reliability.
Microprocessing:Fluid bed technology enables the production of microdosages and microparticles, which is of great importance for the pharmaceutical industry.
Less environmental impact: Fluid bed technology uses fewer chemicals and other auxiliary materials. This significantly reduces the environmental impact.
Lower cost: Process and quality control, small footprint, high productivity and scale ability lead to cost reduction.
