Abstract

An arrangement for lowering the noise level in connection with a cooling layer in a pulp dryer having a heat-insulated bottom wall and top wall constituting a sound-attenuating construction and a wall at the inlet side of the cooling layer also constituting a sound-attenuating construction. At the outlet side of the air flow from the cooling layer in the pulp dryer, sound-attenuation baffles are arranged preferably perpendicular to or inclined in relation to the direction of the air flow and which are placed at a distance from one another.
