11.2.2.2 Check valve (fRESH MILK option)
If constantly washing the milk system by using the special agent the separate washing of the check
valve is not required.
The valve case is semitransparent, so one can see if the cultured milk product is formed inside the
valve.
To wash the clogged valve prepare the washing agent solution and soak the valve in the washing solu
-
tion for 2-3 hours.
It’s recommended to conduct washing by using the solution, prepared from the following concentrates:
Franke Milchreiniger, Specialcleaner for milksystems (Schulz&Sohn GmbH).
After the washing connect the valve to the hot water supply tube by replacing the nozzle with the valve.
Then flush the valve by the hot water flow from the vending machine. The arrow on the valve should be
pointed in the direction of the water outflow.
Note: This is an “emergency” method. There’s no need to adopt this method for everyday check
valve washing as part of the milk circuit.
