  • Everything You Need to Know About Desiccant Drying |

    · Although there are several different types of desiccant dryers, they all work very similarly One unique thing about desiccant dryers compared to other plastic dryers is that they use heated dry air to remove the moisture from resin pellets, rather than ambient air In desiccant drying systems, the air is circulated in a closedloop process, preventing air from exiting the top of the hopper
