7 Cleaning
Make sure the SmartFlow is clean before using it for the first milking session. The main objective of optimizing
the washing and disinfecting process of the SmartFlow is to ensure that no organic and/or inorganic residues can
affect the quality of the milk flowing through the SmartFlow. The secondary objective is to strive for the longest
possible service life of the SmartFlow and its components.
External surfaces of the SmartFlow
The environment of the equipment can have a major effect on its service life. The plastics used in the SmartFlow
have good resistance to hot water with acidic and alkaline milking machine cleaning agents and disinfectants.
However, products containing chloride, iodine, chloride acid, ketones, chlorinated hydrocarbons, aromatic
hydrocarbons, phenols and higher alcohols can affect chemical resistance. Some of these chemicals can be
present in varying concentrations in products such as fly sprays, some teat dip solutions and are sometimes
used as propellants in aerosol cans. Avoid contact of these products with the plastic components of the
SmartFlow.
Also take into account that long exposure of plastics to sunlight (UV A and B) can cause slight changes of color
and/or transparency.
7.1 Clean the SmartFlow
The SmartFlow must be in the cleaning mode to enable cleaning of the inside of the SmartFlow. Vacuum is
applied to change the position of the SmartFlow cleaning valve from the milking mode to the cleaning mode (see
Components (page 7)). When the vacuum is released the valve returns to the milking position.
1. Check that the cleaning agents and the cleaning procedure meet the requirements described in Cleaning
requirements (page 38).
2. Make sure that the SmartFlow cleaning valve is in the cleaning position when the cleaning cycle starts. The
valve is put in the cleaning position by applying a vacuum on the vacuum line for cleaning (see Mount the
cleaning installation (page 25)).
3. Ensure a minimal flow rate of 5 kg/min (176 oz./min).
4. Start the cleaning manually or automatically.
Caution
Make sure that the cleaning vacuum ends when the milking starts.
7.2 Cleaning requirements
The quality of the washing process is determined by:
• Cleaning agents used, type and concentration: Cleaning agents (page 39)
• Temperature: Water temperature and flow rate (page 39)
• Mechanical aspects: Mechanical aspects (page 39)
• Duration of the phases in the cleaning cycle: Cleaning cycle (page 40)
• Amount of water used: Water usage (page 40)
Read the following requirements and instructions concerning the cleaning process before cleaning the
SmartFlow.
