Pros and Cons of Fluidized Beds
The purpose of a fluid bed dryer is to make a solid behave as a fluid. This is usually accomplished by introducing pressurized fluid through particulate medium. After this, the medium will have many similar characteristics and properties as fluids, such as the ability to free flow under gravity. One of the several applications fluidized beds are utilized for is chemical reactors. Some advantages of using a fluidized bed include uniform particle mixing and temperature gradients. Unlike pack beds which have poor mixing, fluidized normally allows for a more uniform product compared to other reactor designs. The reactor can also operate at a continuous state with a fluidized bed.
