Milking arrangement comprising a cleaning arrangement

A milking arrangement, comprising:

• a milk transport line (1);
• a plurality of milk stations (2) connected to the milk transport line (1);
• a receiver (3) connected to the milk transport line (1) and configured to receive milk transported from the milk stations (2) to the receiver (3) via the milk transport line (1);
• a vacuum system (4) configured to supply a vacuum in the milk transport line (1) via the receiver (3);
• a cleaning liquid source (9) connected to the milk transport line (1);
• a controllable injector (10) configured to introduce an amount of gas into the milk transport line (1) that produces a pressure increase in the milk transport line (1) that causes a slug of a cleaning liquid from the cleaning liquid source (9) to be formed and forwarded through the milk transport line (1);
• and
• a control system (19) configured to control an operation of the injector (10),
• wherein the control system is configured to, during a cleaning sequence, control slug characteristics by controlling a vacuum level supplied by the vacuum system (4) and/or the amount of gas introduced via the injector (10), the slug characteristics comprising at least one of a slug velocity of an individual slug, and a length of an individual slug,
• wherein the control system (19) is configured to operate in a first control mode dedicated to a first cleaning sequence, and in a second control mode dedicated to a second cleaning sequence, and
• wherein in the first control mode the characteristics of the generated slug differ from the characteristics of the slug generated in the second control mode.
