Fluidized bed freezing utilizes high-velocity refrigerated air to suspend individual food particles, achieving rapid heat transfer while preventing clumping. This calculation applies the Ergun equation to determine the minimum fluidization velocity and the Whitaker correlation to calculate convective heat transfer rates for IQF tunnel design.
