Abstract [en]

Superheated steam drying is used commercially for lumber, coal, peat, sludges, but has limited installations towards market pulp applications. The technology has the potential for higher drying rates, lower energy consumption, better product quality, and safe operation. In this investigation, a superheated steam dryer (EXERGYPSSD®) was used for evaluation of wet pulp samples collected from pulp mills for comparison with conventional drying techniques. The evaluation of the superheated steam dried pulps indicated that there are potential quality benefits with the technology. Improvements of bulk and absorption capacity was achieved, but more laboratory, and pilot tests are needed to optimize the technology even more regarding pressure, temperature, and residence time in the dryer.
