Abstract
Models were developed and verified to represent the water removal rate data of the two components of combined impingement and through air drying process. Eight physically meaningful parameters were identified, determined, correlated and analyzed. The increasing rate period is extended by impingement water removal. Constant impingement water removal decreases linearly with through flow ratio at a fixed impingement exhaust air flow. Constant through flow water removal is independent of the impingement air. Critical moisture content relates with through flow ratio parabolically. The maximum through flow water removal rate depends on the slope of the paper temperature increase and the extent of the secondary increasing rate period which increases with paper basis weight and drying air temperature, but decreases with through flow ratio and initial moisture content.
