Abstract

A pulp dryer (1) is operative for drying a web (2) of pulp by means of hot air in accordance with the air borne web (2) principle and comprises a cooling zone (10) having a length along which the web (2) is made to travel. The cooling zone (10) comprises a plurality of cooling blow boxes (18, 20) being distributed along the length of the cooling zone (10) and being operative for blowing cooling air towards the web (2). Furthermore, the cooling zone (10) comprises at least one liquid supply device (22, 24) being operative for supplying cooling liquid directly onto the web (2).
