I bought an RC paper dryer a few years ago, one of a number of darkroom bits and bobs I bought when I retired. It's a hot air blower over 3 flat racks. But it makes the paper buckle and curl up, whereas air drying - just lay the prints on newspaper at end of session and leave overnight, they dry perfectly with a slight curl in one plane - is much more efficient.
