Abstract

A device and a method are described, which are used for precipitating beverage sediment from the rinsing mixture of beverage production machines and which comprise a rinsing conduit, a sediment receptacle and a filtering means. In order to design a device of this type in a structurally simple manner such that it can be serviced more easily, it is suggested that the filtering means should comprise a first and a second filter which are arranged one after the other when seen in the direction of flow of the rinsing mixture and which are each provided with filtrate discharge means and that a flow connection for the rinsing mixture discharged from the rinsing conduit and for the filter cake precipitated on the first filter should be provided, said flow connection bypassing said first filter and leading into the sediment receptacle.
