  • a method and a device of the type mentioned is from DE 84 10 075 U1 famous.
  • the device comprises a container for a cleaning liquid and a pump, which sucks the cleaning liquid out of the container and leads it through at least one beverage line connected to the container to form a closed circuit, the device having a water connection piece, a waste water connection piece and a T arranged in the waste water line -piece is provided with a connecting line leading to the container, in each of which a solenoid valve is arranged.
  • a gas connection piece is arranged in the pressure line of the pump.
  • gas in particular air
  • the connection piece arranged in the pressure line of the pump By supplying gas, in particular air, via the connection piece arranged in the pressure line of the pump, the constant flow of the Cleaning liquid interrupted, so that separate amounts of liquid, separated from one another by gas bubbles, result in the pressure line.
  • the gas connection piece is connected to a nozzle system that is arranged in the pressure line.
  • This nozzle system is intended to generate a negative pressure in the pressure line, through which the gas, in particular air, is sucked in automatically.
  • the present invention is based on the object of further developing a method and a device of the type mentioned at the outset in such a way that effective cleaning of the beverage lines is made possible with a simple design.
  • the object is achieved according to the invention, inter alia, by a method having the features of claim 1 in that the air or the gas is introduced into the cleaning liquid in a permanently pulsating manner without interrupting the flow of the cleaning liquid.
  • the cleaning liquid is preferably swirled by the permanently pulsating air or the permanently pulsating gas.
  • a further effect is that the cleaning liquid is subjected to a permanently fluctuating flow rate due to the permanently pulsating air or the permanently pulsating gas. In other words, a pulsating turbulence of the cleaning liquid is achieved.
  • air or a gas, in particular CO 2 is supplied to the cleaning liquid in such a way that the cleaning liquid is swirled.
  • the introduction of air or gas via the membrane air pump or the oscillating valve also changes the flow rate of the cleaning agent in the beverage line. This oscillating turbulence creates a particularly effective cleaning effect.
  • cleaning liquid is mixed with air or gas by the oscillation, with the flow of cleaning agent being uninterrupted by the air or gas. Rather, the introduction of the air or gas swirls the liquid in the beverage line, causing the flow rate to change without interstices resulting from air bubbles in the flow. It is achieved according to the invention that the cleaning liquid is enriched with gas bubbles, so that a mixture of cleaning liquid with gas bubbles whirls through the beverage line and the cleaning effect is achieved as a result.
