Basic of Fluidized Bed Dryer (FBD)
In the pharmaceutical industry, the drying of various materials is a critical process that is required to achieve the desired physical and chemical properties of the final product. One type of dryer that has gained popularity in recent years is the Fluidized Bed Dryer (FBD), which has become a preferred choice for many pharmaceutical manufacturers due to its efficiency, versatility, and ability to handle a wide range of materials. What is a Fluidized Bed Dryer? A Fluidized Bed Dryer is a type of dryer that uses gas or air to create a fluidized bed of particles that allows for efficient heat and mass transfer. In an FBD, the material to be dried is placed on a perforated tray or basket, which is then subjected to a high-velocity stream of hot gas or air. The velocity of the gas stream is high enough to cause the particles to become suspended in the air and form a fluidized bed. The particles are then exposed to the hot gas, which removes moisture and other volatile components, leaving b
