A fluidized bed dryer is a type of equipment used to dry granular materials. It works by passing hot air through a bed of particles, causing them to become suspended and behave like a fluid. This process enhances heat and mass transfer, allowing for efficient drying of materials such as grains, powders, and pharmaceuticals. These dryers are commonly used in industries like food processing, chemical manufacturing, and pharmaceuticals. The design allows for uniform drying, reducing the risk of overheating and ensuring consistent product quality. Fluidized bed dryers are valued for their energy efficiency and ability to handle a wide range of materials.
