<p>The invention relates to a steam dryer, in particular for drying concentrates, which dryer comprises a drum (17), inside which a steam distributor pipe (27) and a steam tube system (18) are centrally placed, which steam tube system is formed of a plurality of steam tube groups (181-18n) arranged around the steam distributor pipe (27) in a direction transverse to the length of the drum (17). The steam tube groups are situated in the direction of the length of the drum (17) at a distance (L¿2?) from one another substantially over the entire length of the drum (17), and the steam tubes extend in them transversely to the radius of the drum (17) and in the radial direction of the drum concentrically at a distance from one another. The drum (17) of the steam dryer (10) is arranged to rotate by means of actuators (13, 14, 29, 15) and on support of support means (28, 16) during drying together with the steam tube system (18) situated inside said drum (17) and formed of a plurality of steam tube groups (18?1-18n¿).</p> |
