Fluid Bed Technology

Our fluid bed processors:
technology for innovative products

Drying, granulation, coating, encapsulation, agglomeration or instantization: with our fluid bed processors we make up individual products as powders or granulates with defined properties.

Your partner for contract production by fluid bed

Gentle drying of thermosensitive products

Unlike conventional spray drying, fluid bed technology permits drying of the products at very low temperatures. That is because the drying temperature can be adjusted separately from the drying time in the process.

Tailor-made product development

In close collaboration with our customers we develop tailor-made products on the pilot fluid bed processor in our laboratory. The sample batches produced there later constitute the basis for reproducible results on the commercial-scale production plant.

Fluid bed technology for a diversity of applications

Our multifunctional fluid bed processor offers a large number of technical options and was designed specially for the wide range of applications in contract manufacturing. The processor permits both batch and continuous operation. Features such as Wurster inserts, in-line sifting and grinding and various ports enabling adjustment of the nozzles for top or bottom spraying equip the processor for (almost) any application.
