ABSTRACT:
In a process and apparatus for drying small articles in a process container, such as closure elements of pharmaceutical vessels after a treatment of the closure elements, an air-permeable support is arranged beneath the articles to support them and prepared preheated air is fed to the interior of the process container and through the support to dry the articles while they are resting on the support. An additional air mass flow is at least once briefly passed under the support during the drying operation, to lift and thereby turn the small articles to ensure at least substantially complete drying thereof.
