Abstract:
1. A method for replacement of at least one expired component of a pourable medium, comprising the steps of: providing a container having a removal output at one side for the at least one expired component of the pourable medium, and providing at an opposite side of the container a supply input into which a quantity of at least one of fresh pourable medium and a fresh component is supplied; providing a valve system connected to said supply input for delivery of a predetermined quantity of at least one of said fresh pourable medium and said fresh component, the valve system comprising at least one valve and a control module, said control module having a time meter having an output connected to control said at least one valve which sets a change interval during which said at least one fresh pourable medium and a fresh component is supplied by said valve system; providing said removal output as a nose whose tip defines a predetermined pourable medium fill level in the container, said nose being part of an overflow designed as a trap; and when the fill level rises over the predetermined pourable medium fill level defined by said nose, the expired component is automatically removed over the overflow so that the fill level in the container regulates itself dependent on the predetermined pourable medium fill level and the supply input quantity.
