Semi-continuous fluidized bed dryers. Apart from these, a fluid bed dryer design can also be: Vertical fluidized bed dryer. Horizontal fluidized bed dryer.
It explains that fluidized bed dryers use hot air or gas to fluidize solid particles, allowing for rapid and uniform drying. There are two main types - batch and continuous. Batch dryers allow control of residence time for uniform drying, while continuous dryers can dry materials with high moisture content and achieve piston-like …
The steps involved in the fluid bed drying process are: Material is loaded into the fluid bed dryer. A stream of hot air is forced through the bed of material particles from the bottom of the dryer. As the air flows through the bed, it causes the material particles to become suspended and form a fluidized bed.
The mixing and drying behavior in a continuous fluidized bed dryer were investigated experimentally by characterizing the residence time distribution (RTD) and incorporating a micromixing model together with the drying kinetics obtained from batch drying. The RTD of the dryer was modeled using a tank-in-series model.

Pneumatic dryers dry materials by suspending them in a column and blowing hot gases through to evaporate moisture. Fluidized bed dryers fluidize wet material in a bed with hot gases to promote rapid mixing and drying. Sub-fluidized conditioning is also described, which allows longer residence times with less mixing than typical fluidized beds.
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".

The drying unit of a continuous from-powder-to-tablet manufacturing line based on twin-screw granulation (TSG) is a crucial intermediate process step to achieve the desired tablet quality. Understanding the size reduction of pharmaceutical granules before, during, and after the fluid bed drying process is, however, still lacking.
