Fluid Bed Dryer

The Fluid Bed Dryer is used in quality control, sample preparation. It permits the gentle drying of organic, inorganic, chemical or pharmaceutical bulk materials without localized overheating. Suitable materials can be coarse, fine, crystalline, fibrous or leafy. The powerful fan of the fluid bed dryer ensures optimal air throughput so that the products to be dried are loosened up and thoroughly mixed resulting in short drying times. With the interval operation the fluidized bed is mixed even better. Temperature, drying time and air volume can be set digitally and adjusted continuously.

The Fluid Bed Dryer now offers an extended maximum time setting, increased from 99 minutes to 9 hours, with several intermediate steps. This enhancement allows users to initiate longer drying processes, including overnight operations, without any risk. Continuous drying remains an available option.

FUNCTIONAL PRINCIPLE

Drying in the Fluid Bed Dryer makes use of the fluidized bed process, a technique similar to the one used in large industrial dryers. Ambient air is drawn in through a filter. A blower moves the air across the heating elements, and ultimately forces it through the perforated plate and into the detachable drying container. The solid particles are blown upward and dispersed and thus kept separate from one another. This helps to avoid a caking and sticking of the particles as it often occurs when other drying methods are used.
