Reconciliation of Mass and Energy Data Measurements

Reconciliation of Mass and Energy Data Measurements

The paper analyzes the propagation of random errors through mass and energy balance calculations and discusses the presence of systematic errors in measurements obtained during the operation of the dryer. The inaccuracy of temperature measurements in the presence of radiation is discussed, as well as the effect of air infiltration inside the dryer.

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.
