ABSTRACT:
An immersion tube dipping into a fluid is connected via a valve and via a 3/2-valve to a condensate line and to a working line. In the sterilization position, vapor flows through the valve and through the 3/2-way valve and the valve is in a position which is open to the head space of the vessel and to the tube. As a result, all of the inner space of the vessel is exposed to the same pressure. In the operating position, the valve connects the duct only to the interior of the immersion tube, while the connection to the head space is blocked. All components connected to the line are sterilized by vapor.
