Abstract

Treating weak-to medium-active ion exchanger resins which are dried in a drying container by means of heat and in a vacuum, before they are transported into a storage container, the heat being introduced by heat conduction via the drying container into the ion exchanger resins. The heat is conducted via metallic heat transfer surfaces into the bulk of the resins leaving a core of at most 100 mm thickness. Steam from the moisture in the resin is conducted at the same time into a condenser via a discharge line, with an underpressure of 300 mbar or less.
