Fundamentals Of Spray Drying
Saturation point is the air temperature at which any further temperature drop will result in condensation. saturated air has equal dry bulb, wet bulb and dew point temperatures. drying air rate (aa) is usually expressed as the mass flow of ambient air per hour (kg/h) and includes both the amount of dry air (ad) and water vapour (av) which can be calculated using equations:
