Fluidized Bed Dryer -FBD: Principle, Working Process
The principle behind a Fluidized Bed Dryer revolves around the concept of fluidization. Fluidization is a process in which solid particles are made to behave like a fluid by passing a gas or liquid through them. In the case of FBDs, a stream of hot air or gas is passed through a bed of solid particles, causing them to become suspended and act ...
