Mass Energy Balance Spray Dryer

Jun 01, 2019 For example, in a conventional spray dryer, about 3900 W of energy-input is required to process 1 kg/s of a 40% w/w solution using 15 kg/s of dry airflow (0.01 kg water vapor/kg dry air). From this amount, 85% of the energy is used to heat the air stream (m.C p .dT) up to the inlet temperature of the spray dryer (200 C). Get Details
