Multi-Bed Carousel Dryers

Carousel dryers were popular in the late 80’s and 90’s but thousands are still in use. They are based on desiccant bead technology but instead of the beads being contained in dual stationary beds, the beads are contained in three tanks mounted on a rotating turntable. These dryers have the same high-energy usage disadvantages as dual bed dryers. They have even higher maintenance requirements because of the multitude of moving parts and seal failure.

Newer technology desiccant wheel, membrane or vacuum dryers are replacing carousel dryers.
