摘要

Regeneration apparatus for moisture-laden drying cartridges (24a, 24b) used to dry air from a polymer granule dryer (12) comprises a fan (21) which blows atmospheric air heated to 220 -300[deg]C in counter current through the cartridges. They are then cooled by blowing some of the air from the dryer through them in the normal operating direction using a second fan (14).
