Abstract

An apparatus for the evaporation of active ingredients incorporated in cellulose or some other, at least approximately dimensionally stable carrier material has heating means arranged in a housing to evaporate the active ingredients. A support is provided for replaceably holding an active ingredient carrier above the heating means. The active ingredient carrier is in the form of a column and is optionally inserted replaceably, with its longitudinal dimension placed vertically, in a sleeve which is adapted in its form and dimensions to the active ingredient carrier and is open at the top and bottom. The sleeve is situated inside the housing and spaced apart from the wall of the housing on all sides, said housing having exhaust gas openings at the top.
