4.2.10 Filling station with vacuum filling (9)
P
Q
In addition to the conventional filling, the machine is equipped with a vacuum filling
system.
The filling heads of the vacuum chamber (P) are placed on the syringes. The va-
cuum valves open and the vacuum lines and the syringes are evacuated via va-
cuum tank.
Then, the filling needles (Q) move into the syringes and fill them with the provided
product via rotary piston pumps. When the filling needles have reached a certain
position during the filling process, the vacuum valves close after a presettable time.
After the filling, the vacuum chamber is lifted up from the syringes. During the lifting
process the filling heads of the vacuum chamber are vented via venting valve of
the vacuum filling station so that they don’t pull syringes up and out of the nest.
The vacuum pump continuously evacuates the vacuum tank.
Sterile filters prevent product contamination during venting.
