Procedure and apparatus for the treating containers such as plastic bottles in a bottle filling plant or containers in a container filling plant

A sterilization arrangement comprising:

• a first delivery arrangement to introduce heated hydrogen peroxide into a container;
• a second delivery arrangement to:
• introduce a heated gaseous and/or vaporous activation medium into the container at a first volume flow rate in a first step;
• and
• subsequently introduce said activation medium into the container at a second, lesser, volume flow rate in a second step;
• a monitoring arrangement to monitor, without contact, the temperature of said container or the wall of said container;
• a computer control arrangement to regulate said second volume flow rate based on the monitored temperature;
• said second delivery arrangement comprising:
• activator heads for dispensing activation medium into containers;
• and
• control devices, comprising throttles or valves, configured to control the flow of said activation medium to said activator heads;
• a detection arrangement comprising temperature detection devices for contactless measurement of the temperature of the surfaces of solid bodies;
• each temperature detection device being positioned on or at each of said activator heads or a plurality of said activator heads;
• and
• said computer control arrangement is configured to control said first delivery arrangement to introduce said heated hydrogen peroxide at a constant or substantially constant temperature over a constant or substantially constant time with a third volume flow that is controlled based on the monitored container temperature so that the container temperature remains substantially below the temperature of the heated hydrogen peroxide.
