Selecting a fluid-bed dryer
The fluid-bed dryer's high operating efficiency, ease of use, and low maintenance costs make it an attractive option for bulk solids drying applications. This article explains how to select a fluid-bed dryer based on your material's characteristics and your drying requirements.
A fluid-bed dryer can process many types of bulk solid materials at a wide range of moisture levels and operating temperatures. Drying rates can range from a few hundred pounds per hour to more than 100 tons per hour, with equipment size varying from a 1-foot-diameter circular pilot dryer to a 20-by-50-foot-long rectangular production unit. But versatility isn't the dryer's only benefit. The heat and mass transfer between the drying air and the material being dried is highly efficient, giving the fluid-bed dryer a short residence time. The dryer is also easy to operate, can run in batch or continuous mode, and has fewer mechanical components and a smaller footprint than many other dryers.
