<p>A cleaning device for beverage drafting and dispensing systems, especially dispensing systems for carbonated beverages such as sodas, colas and fruit juices, as well as beer, utilizes primarily water and a liquid chemical cleaning agent which can be induced into the drafting lines from a storage container, and from which it can be removed again after a prescribed settling time. The system includes a hydraulically controlled change valve, controlled via three solenoid valves, pressurized with tap water and enclosed in a valve housing which contains a hydraulically movable piston which, in the operating "tapping" position, provides the first flow. Such flow is intended for the beverage. On the lower part of the valve housing, the beverage container adaptor equipped with a check valve is connected and on the upper part of the housing, a line connection is made with the beverage line leading to the tapping cock. This connection through the device is accomplished by a channel surrounding the piston in the tapping position.</p> |
