Abstract
Paper drying is a very important unit operation and a highly energy intensive operation in the paper industry. Various studies have been made to discuss the effect of various variables on the drying behavior of the paper. Extensive efforts have been made to reduce the energy requirement in this operation.
This study tries to find the effect of basis weight, refining level on the drying behavior of the paper of both hardwood and softwood. The basis weight, the degree of refining and type of wood affects significantly the drying rate, the drying time and the contact coefficient between the paper web and the metal shell. It is found that the drying rate, the drying time and the contact coefficient increase with the increasing basis weight. The degree of refining also shows its effect on these behaviors, as with more refining, the drying rate goes down and so the drying time increases. The effect of type of wood is also very much significant on the drying rate and the drying time, as less drying rate observed of softwood sheets, so the sheets took more drying time in compare of hardwood sheets.
