In general, those big drum dryers with a blanket, and motorized transport were designed to work with single weight glossy paper to dry large production runs of single weight glossys for press releases, etc. Most had a highly polished "ferrotype" drum surface to give the glossy prints the high gloss. Don't work so well for drying prints matte, as you have to turn them face-down on the blanket, and they pick up lint as they dry that sticks to the surface. Ugh.
Also, the blankets over time absorb residiual chemistry from the paper and then transmit this residual contamination to all prints thus shortening the lifespan of all the prints. These big dryers were used for work that was not intended to be archival.
Best to air dry double-weight glossy "F" surface paper on screens, to give a semi-gloss surface, and then flatten in a dry-mounting press for a few seconds, after dry.
Never try to dry "matte" or "silk" surface fiber paper face up on these dryers, as the drum will try to put a glossy surface on them with terrible results. Splotches.
I would imagine that a person could find one of these for "free" just for hauling it away, from many places.
