For this combined drying process the fundamental characteristics were determined using a unique facility in which air convection drying of paper could be investigated over the full range from pure impingement to pure through drying. As well as light weight paper the program tested heavier sheets, of printing paper grammage, which are not currenfly dried industrially by either impingement air or through air drying. Analysis is complicated by the two component processes becoming nonadiabatic when carried out simulianeously. Relative to pure impingement drying, for the combined process the water removal rates in the impingement exhaust are sensitively reduced by through flow. Through flow exhaust water removal rate curves are strikingly different from pure through air drying by the addition of a new rate period, termed the secondary increasing rate period, when the paper temperature is driven up by the falling rate period of impingement water removal. Parameters of the models for the combined process were related to |
