rotary dryer or fluid bed dryer - feeco international inc

Rotary dryers require less energy to dry material, and energy consumption is reduced when running at lower capacities. Fluid bed dryers are considered to be more thermally efficient than rotary dryers, however. This is because the heat transfer is maximized due to the fluidization effect; each granule is surrounded by the drying air

the truth about fluid bed dryer efficiency

the truth about fluid bed dryer efficiency

Reality: Fluid bed dryers and rotary dryers are comparable in terms of fuel consumption. While it is true that fluid bed dryers offer some enhanced heat transfer compared to rotary dryers, fluid bed dryers use lower inlet gas temperatures (typically around 900℉ vs. the 2100℉ commonly used in rotary dryers). So while rotary dryers may offer less thermal efficiency in theory, the higher temperatures they employ allow for increased efficiency, making fuel consumption …
