Fluidized bed dryer | Tema Process
Fluid bed dryers work on the principle of fluidization, a process in which hot air is introduced into the spaces between solid particles. Each particle is in direct contact with, and surrounded by, the hot air – creating an efficient and uniform drying process. The material is dried in the first section of the machine and cooled in the second.Web

Flow through Packed Beds and Fluidized Beds
A fluidized bed is a packed bed through which fluid flows at such a high velocity that the bed is loosened and the particle-fluid mixture behaves as though it is a fluid. Thus, when a bed of particles is fluidized, the entire bed can be transported like a fluid, if desired. Both gas and liquid flows can be used to fluidize a bed of particles.Web
