摘要： The invention concerns a steam dryer, in particular a steam dryer intended for drying of concentrate materials, which dryer comprises a cylindrical, rotatable drum (11), in whose interior a set of steam pipes (12) consisting of a number of pipes has been fitted to revolve along with the drum. The steam intended for drying of the material has been arranged to be supplied into the set of steam pipes (12) by means of steam supply devices fitted at a first end (10A) of the dryer, and at the opposite end (10B) of the steam dryer (10), conveyor (16) has been installed to supply the material to be dried into the drum (11) interior. The dried material (25) has been arranged to be discharged through the first end (10A) of the dryer. The set of steam pipes (12) is composed of a number of pipe elements, each of which is composed of two axial pipes (12a, 12a′) parallel to the longitudinal direction of the drum (11) and of a number of pipe arcs (12b) fitted in the cross direction of the drum (11) and at a distance from one another in the longitudinal direction of the drum, which pipe arcs interconnect the two axial pipes of each pipe element. At the first end (10A) of the steam dryer (10), a steam distributor header (17) has been fitted coaxially with the drum (11), through which header the steam meant for drying has been arranged to be fed into each of the pipe elements, and, in a corresponding way, through which header the condensate coming from the pipe elements has been arranged to be removed.

摘要： A drying apparatus comprises a cylindrical rotatable drum (1), the inside of which is provided with a steam pipe system consisting of heat transfer elements (7), to be rotated with the drum. The heat transfer elements (7) are detachable from and mountable on the drum (1). Material to be dried is fed to a first end of the drying apparatus, the material being arranged to be discharged through a second end of the drying apparatus. The heat transfer element (7) is formed as a uniform packet of several longitudinal pipes (8) and connecting pipes (9) between them in such a way that the structure of the heat transfer element is formed self-supporting and that this self-supporting packet is attached to the drum (1) frame with fastening that allows heat expansion.
