The moist solids are lifted from the bottom and suspended within a stream of air (fluidized state). The new gas Encompassing every granule to wholly dry them. Thus, supplies or granules are uniformly dried.
The particles are lifted and after that fall again randomly so which the resultant combination of reliable and gasoline acts like a boiling liquid. This situation is termed a fluidized state. The excellent gasoline-sound Get hold of brings about improved heat and mass transfer than in static and relocating beds.
