Evaporator for extracting and filtering active substances from biological materials by heating

Abstract

The invention relates to an evaporator for extracting and filtering active substances from biological materials by heating, characterized in that an active substance precursor in the form of a hollow cylinder, the outer walls of which are permeable to aerosols, is arranged in a heating chamber, wherein the active substance precursor is surrounded by a heating sleeve which is seated displaceably on the active substance precursor, wherein the length of the active substance precursor is a multiple of the width of the heating sleeve, preferably the width of the heating sleeve is approximately 5% to 25% of the length of the active substance precursor, so that a plurality, preferably approximately 4 to 15, partial regions of the active substance precursor can be heated individually, so that active substance provided by the active substance precursor can be smoked at least in regions and/or an aerosol which comprises active substances provided in regions by the active substance precursor can be generated.
