There were lots of dry-in-dry-out processors but none that can be used the way you wish. Ektaflex is one that comes to mind as well as Ektaline and a few others. Some ran at rather high speed and took continuous rolls of paper.

There are a series of small tank processors that Jobo sells for this purpose as well. The Nova series is very nice. I use their drum processor for B&W up to 16x20 as well as color.
