ABSTRACT:
A safety arrangement is utilized for separating liquids including milk, extraneous water, and cleaning medium in a system which has two supply conduits, a first running container for receiving the liquids from the supply conduits, a negative pressure device connected with the first running container and a pump conveying liquids from the first running container to separate receiving containers. The arrangement has two first sensing elements in the supply conduits upstream of the first running container, and a second conduit downstream of the latter and upstream of the receiving containers. Close-off valves are located between the first sensing elements and the first running container. An electronic control device connects the sensing elements with the close-off valves so as to actuate the latter in response to sensing of characteristics of the liquids at the above-mentioned locations, by the sensing elements.
