Abstract
The present invention discloses a method and an apparatus for sterilizing a container prior to filling the container with a pumpable food product such as milk, juice, water, soup or yogurt. The present invention uses UV radiation to transform oxygen into ozone at the filling station. The ozone flows into the container thereby sterilizing the container. Subsequently, the container is filled with a desired product and sealed. A preferred source of UV radiation is an excimer lamp.
