CANVASA II + II can filling machine operating manual

Filling process parameterization:
Four parameters are essential for the filling process:
Input pressure (set via tank pressure); experience indicates 1.3 to 1.6 bar
Preload pressure; experience indicates a relative pressure (pressure difference) of 0.3-0.4
bar.
Filling speed; experience indicates that a slow initial speed (e.g. 40mm/s) is recommended,
which can then be increased gradually.
Filling acceleration; experience indicates that a high value is recommended here (e.g. 90mm;
the acceleration is specified as the length of the acceleration ramp, i.e. the higher the value,
the smoother the acceleration).
The objective is to find the parameters in which the process runs at maximum speed and the beer
is still filled into the can almost free of foam or at least low in foam.

Setting of the high-pressure injection
The effect of the high-pressure injection can be influenced by three control variables:
Begin high-pressure injection
High-pressure injection duration (i.e. dwelling time of the nozzles above the cans)
