Fluid Bed Dryer

A fluidized bed dryer (also called a fluid bed dryer) is a process equipment used extensively to reduce the moisture content of food, pharmaceutical, chemical powder, and granules.What is Fluid Bed Drying? Fluid bed drying is a process by which particles, typically greater than 50 microns, are fluidized and dried. For the material to become fluidized, the particulates are placed under conditions that cause it to behave like a fluid.In fluidized bed processes, small carrier particles that remain suspended in fluid are used as a support media (in the form of fine grains of sand) for biofilm growth, specifically the growth of nitrifying bacteria. The beds expand under pressure from forces associated with the upward flow of water.
