Fluidized bed drying is a process used to remove moisture from granular materials. In this method, hot air is passed through a bed of particles, causing them to become suspended and behave like a fluid. This enhances heat and mass transfer, allowing for efficient drying of the material. The fluidized bed consists of a container where the particles are evenly distributed. As the air flows upward, it lifts the particles, creating a uniform drying environment. This technique is commonly used in industries such as pharmaceuticals, food processing, and chemical manufacturing to ensure consistent product quality.
