4. Hot air convection dryer and energy savings
4.1 Overall balances for the complete dryer
Global balances are established on the dryer's "inputs/outputs", and they allow the most characteristic quantities to be calculated a priori or ascertained a posteriori: the evaporation rate (kg/s), the energy consumption (kW), the energy efficiency evaluated by the "mass energy consumption" (CEM in kJ consumed/kg of evaporated water), the required dry air flow
