ABSTRACT:
A device for drying textile material has a closed housing accommodating a conveying means comprising a sieve drum that is under a suction draft and that is covered to prevent flowthrough of gases in the zone not contacted by the textile material; a fan associated with an end face of the sieve drum for withdrawing the gaseous treatment medium from the sieve drum and for blowing the gaseous treatment medium back into a space around the sieve drum; and an annular gap provided between a fan intake connection, or duct, and a wall provided with the drum spider for supporting the sieve drum. The gap is surrounded by an annular duct open toward the gap into which terminates burners of a direct flame heating unit for heating said gaseous treatment medium.
