Abstract
The invention relates to a method and an apparatus for sterilizing packaging material, in particular packaging containers by means of a liquid sterilizing agent containing hydrogen peroxide, in which a mixture consisting of sterilizing agent and air is vaporized within a spray pipe (18) and guided positively within the spray pipe so that a very good vaporization capacity is achieved. In order to achieve this, a rotary flow movement along a central axis is imparted to the mixture of vapor and air by swirl bodies (19, 21) and coil spring inserts (22, 23) inserted alternately therewith inside the spray pipe (18) and the liquid which has not yet vaporized is given a flow direction in opposition to that of the main stream of the mixture and consequently a long residence time of the liquid on the pipe wall of the spray pipe (18) is achieved.
