Abstract
In a process for low particle sterilization of temperature resistant containers (glass bottles), the containers are continuously sterilized by radiant heat in a continuous heating furnace and then cooled by highly purified filtered air. One essential factor for obtaining the freedom from particles is the provision of a non-turbulent stream of highly purified air maintained in the continuous heating furnace in a direction parallel and opposite to the direction of movement of the containers.
