Abstract
In a tunnel-like region of a sterilizing tunnel, containers are advanced by means of a conveyor device. For sterilization, a heated air flow oriented vertically in the region of the containers is used, which is generated by means of a fan and a heater. To prevent particles from being torn out of a sterile filter during the heating phase, there is a provision for adapting the rpm of the fan during the heating phase. According to the invention, this rpm adaptation is done by ascertaining the requisite rotary speeds of the fan beforehand at both room temperature and the sterilization temperature, whereupon a control unit of the sterilizing tunnel, on the basis of a predetermined functional relationship, raises the rpm of the fan as the temperature of the air flow is raised.
