Embodiment Construction

[0037] Hereinafter, preferred embodiments are described based on the accompanying drawings. In this case, identical, similar or identically acting elements are identified with the same reference numerals. In order to avoid repetition, repeated descriptions of these elements are partially omitted in the following description.

[0038] figure 1 A schematic sectional view of the device 1 for introducing gas into the container 8 to be filled with a filling product is shown schematically in a position during flushing of the container 8 . The gas is fed to the gas inlet 2 via a gas feeding device (not shown here). The gas inlet 2 can be opened and closed by means of an inlet valve 20 . Since the inlet valve 20 is in the open position, all gas passes through the gas inlet 2 in the flow direction S. Downstream of the inlet valve 20 in the direction of flow S, the gas inlet 2 is divided into a flushing line 4 and a pretensioning line 5 , both of which lead into the gas outlet 3 . ...

Abstract

The invention relates to a method and a device (1) for introducing gas into a container (8) to be filled with a filling product, the device comprising a gas inlet (2) switchable via an inlet valve (20), the gas inlet For feeding gas to the gas outlet (3) into the container (8) to be filled, wherein the gas inlet (2) is divided into a flushing line ( 4) and the pretensioning line (5) for flushing the container (8) and the pretensioning line for the pretensioning container (8), wherein the pretensioning line (5) has a function for opening and Closing of the automatically switched backpressure valve (6) of the pretension line (5), based on the upstream pressure (p1) present in the pretension line (5) upstream of the backpressure valve (6) and The pressure relationship of the downstream pressure (p2) present downstream of (6) The back pressure valve (6) switches automatically between an open position and a closed position.

Description

technical field [0001] The invention relates to a device and a method for introducing a gas into a container to be filled with a filling product, preferably in a beverage filling plant for introducing an inert gas into a container to be filled with an oxygen-sensitive filling material in the container. Background technique [0002] Devices for introducing gas into containers, especially for use in beverage filling plants, are known. It is common here, especially when filling containers with highly oxygen-sensitive filling materials, to fill the container with an inert gas, usually CO, before the actual filling with the filling product. 2 Flushing in order to achieve a gaseous atmosphere with the lowest possible oxygen concentration in the container. In this case, the delivery of the inert gas usually takes place via the supply of clean gas or by means of gas from the headspace of the container providing the filling. To flush the container, a common flushing and counterpre...
