They can only be used for drying granular particles.Comparative Analysis: Rotary Dryer vs. Fluid Bed DryerNow let us compare the rotary dryer and fluid bed dryer based on various parameters:Operating principle:Rotary dryer: A rotary dryer works by rotating the raw materials inside a cylindrical drum that contains the material to be dried. The cylindrical drum is exposed to hot air, gradually removing the material's moisture content. The materials are then moved into the cylinder, allowing even drying conditions.Fluid bed dryer: The fluid bed dryer operates on the principle of fluidization. In a fluid bed dryer, moisture is removed by passing hot air over materials in a granular state. This causes the particles to behave like boiling liquids. It also allows for the transfer of heat from the material in an even manner. These fluid bed dryers are more effective in drying materials that are in a granular state.Energy-efficiency:Rotary dryer: In the case of a rotary dryer, as the drying takes place in a closed system, the devices are energy efficient. A lot of heat isn't lost to the surroundings because of the closed structure of the dryer. The heat transfer is also quite good.Fluid bed dryer: A lot of energy is involved in drying the materials in a fluid bed dryer. This causes you to spend more on your electricity bill. Also, the energy required to get the particles to a fluidized state is more, thereby requiring additional energy.Material Handling Capabilities:Rotary dryer: You can efficiently use a rotary dryer for drying materials of different shapes and sizes including free-flowing materials, which makes them a perfect choice for multiple industries. So, it doesn't matter what the size of the materials are, the drying process can take place efficiently. In fact, particles of larger sizes can also be fed to the dryer for efficient moisture removal.Fluid bed dryer: Fluid bed dryers can only remove moisture from smaller particles that can be fluidized. So, in case the materials are larger, then the drying will not be as effective as the rotary dryers. So, there is a restriction on the choice of material that can be used for drying purposes.Maintenance Requirements:Rotary dryer: In the case of rotary dryers, many components are involved in the drying operation. You require a rotating drum, wearing seals, etc. All these components require regular maintenance. You will also have to clean up the different components for efficient operations.Fluid bed dryer: In the case of fluid bed dryers, the maintenance required is considerably less.
