Chapter I: Fluidisation
Fluid bed or fluidised dryers. What does fluidised bed mean? How does a fluidisation work? What is the purpose of fluidisation? Etc.
In a couple of chapters, we will explain more about this technology/process and where the system can be used.
Fluidisation Step-by-step
- A fluid bed dryer has a Perforated plate
- Hot air is blown trough the perforated plate
- The hot air gets distributed
- The product lies on the perforated plate, and will float due to the air pressure
- The heat gets transfered past the products that float
- Floating of the product in the air is called “fluidisation”
Advantages of fluidisation:
-Provides superior drying result
- High rate of moisture removal
- Optimal heat transfer results in shorter residence time (smaller equipment)
