Abstract
In this paper combined air-cylinder drying process is studied using
drying simulation model. Combined air-cycled drying process means impingement
drying on a cylinder covered with permeable fabric. Paper was dried I single
drying cylinder covered with impingement box to see the differences of the
drying methods. Focus of the study has been in drying rate improvement
compared to the sum of separate processes. Also differences of the temperature
profiles during drying are compared and discussed. Results show more than 50%
drying rate improvement in combined drying compared to sum of separate
processes when dryness is more than 80%. Drying rate is increased to a level
of normal impingement drying. Reason for this improvement is enhanced mass
transfer from dried paper and lowered paper temperature in drying due to
cooling effect of the impingement drying.
