Drying

In the drying section the pulp is dried with hot air, normally from a dryness of 45-55% dry solids to the final dryness of about 90% dry solids.

Dewatering takes place by evaporation in the dryer section. In both airborne drying and flash drying the pulp is dried by convection. In convection drying heat comes from hot air surrounding the web. 

Airborne dryers are normally used for chemical pulping and flash dryers for mechanical pulping.
