Abstract

The invention relates to an airborne pulp dryer with cross-directional blow boxes. The blow boxes (13) are arranged as superposed drying decks (11) having in between a passage (15) for a pulp web (14). The pulp web (14) is arranged to run horizontally in a zigzag manner via the drying decks (11). A part of the blow boxes (13) are situated above the passage (15) and the rest of the blow boxes (13) are situated below the passage (15). Between two passages (15) there are two kinds of blow boxes (13) arranged alongside. The blow boxes (13) are namely combo boxes (22) having both top nozzles (23) and bottom nozzles (24), and bottom boxes (25) having top nozzles (26) only and being lower than the drying deck (11). Also the blow boxes (13) are stationary.
