Abstract:
A method for vaporising and super-heating a sterilising agent, which is brought to a first temperature and vaporised with the aid of a heated surface, and the vapour is subsequently brought to a second, higher temperature and super-heated by means of heating elements, whereina) the sterilising agent is sprayed onto the heated surface, which is heated to a first temperature, b) which is lower than a surface temperature at which film boiling begins, c) the first temperature of the heated surface is sensed and converted into signals for controlling the heating elements for super-heating, and d) the sterilising agent vapour is heated in a counter flow such that the first temperature is kept substantially constant by means of the second, higher temperature and by means of a flow of heat directed in the opposite direction to the flow of vapour.
