Turbulence has the greatest positive effect on the cleaning of the milk meter. Also the availability of sufficient
cleaning liquid in all phases of the cleaning process is important.
Turbulence can be promoted by air injection and/or increased vacuum (5 to 10 KPa above milk vacuum). A
sufficient vacuum level is essential for the proper functioning of the SmartFlow cleaning valve and the drainage
after each phase of the cleaning process (phase separation).
7.2.4 Cleaning cycle
In general the cleaning cycle exists of the following phases:
1. Pre-rinse: Cold or lukewarm pre-rinsing without circulation with clean water to remove the milk residues.
The length of this phase mainly depends on the time needed to thoroughly rinse and drain all internal
surfaces of the milking installation.
2. Main wash: Hot main wash with circulation of water with cleaning agent.
The length of this phase mainly depends on the instructions of the manufacturer of the cleaning agent en de
minimal water temperature (± 45°C (113ºF)) . The main wash takes on average 5 to 10 min.
3. Rinse: Cold rinse without circulation to remove the last remnants of the cleaning agent used in the main
wash.
The length of this phase mainly depends on the time needed to thoroughly rinse and drain all internal
surfaces of the milking installation.
7.2.5 Water usage
The amount of water needed for the different phases of the cleaning cycle depend on the number of milking
points and the construction and configuration of the milking installation.
For modern milking installations with wide milk pipes, an average amount of 5 l (1.3 gal.) per milking point can
be used as a guideline.
The pre-rinse and rinse phases of the cleaning cycle do not use circulation and therefore need sufficient water to
thoroughly clean all internal surfaces.
The water usage can be reduced by an optimized timing of the opening and closing of the valves in the cleaning
installation and the milk meter.
7.2.6 Cleaning program settings
The cleaning program settings depend on the cleaning equipment used, but the settings must give the following
results:
1. The central valve in the vacuum line must control the SmartFlow cleaning valve.
2. The SmartFlow milk meter must be completely filled with water for more than 50% of the time during each
of the three phases of the cleaning cycle (see Cleaning cycle (page 40).
