ABSTRACT:
An automated cleaning device for beverage drafting/dispensing systems uses cleaning balls to clean tap lines. The cleaning balls are pushed through the lines by clean, pressurized water. The cleaning device includes a dual-acting hydraulic cylinder which is operated by means of an electric control system and solenoid valves. This dual-acting hydraulic cylinder is an integrated feature of a sliding valve system which retrieves the cleaning balls from a retention hopper through a cylindrical slide, inserting the cleaning balls alternately into either a tap line leading to a tapping cock or into a tap line leading to a keg, assisted by pressurized water. In the drafting/dispensing position, the sliding valve provides an uninterrupted connection between the two lines. The sliding valve can be operated from a remote switching location or manually.
