14 -
Dispense from the valve until the detergent solution begins to come out (typically after 15 seconds / 5
mt of python); open the valve for 15 sec and stop for 5 sec: repeat for 4 times, open the valve for 30 sec.
15 -
Disconnect the connector from the detergent solution container, and connect a tank containing clean
potable water to syrup circuit at the same pressure level as for the syrup.
16 -
Dispense from the valve to flush the syrup circuit.
17 -
Disconnect the connector from the clean water container, and connect a tank containing the sanitizing
solution described above to syrup circuit at the same pressure level as for the syrup.
18 -
Dispense from the valve until the sanitizing solution begins to come out (typically after 15 seconds / 5
mt of python);
19 -
Once the contact time has elapsed (15-20 min), thoroughly rinse the line with clean water (see points
3 - 4 of this procedure). Check the pH of the output water is the same as that of the input water (use litmus
paper or a pH meter).
20 -
Reconnect the connector to the syrup container, and intervene on the dispensing valve until only syrup
comes out of it.
21 -
Turn on the water tap on the dispensing valve again, and replace the cover.
22 -
Check the soda - syrup mix ratio of the valve (chapter ”4.8” pag. 39).
23 -
Repeat these operations for all the syrup lines.
LINES WITH A BAG-IN-BOX (BIB)
1 -
Remove the cover from the dispensing valves, and turn off the water taps.
2 -
Disconnect the connector from the syrup container, and rinse it in clean hot water.
3 -
You will need to acquire an adapter (for example, recovering one from an old BIB), to be connected to
the suction line in place of the BIB in order to keep the connector permanently open.
4 -
Stop the supply of CO
2
or compressed air to the pneumatic pumps.
5 -
Intervene on the lever of the dispensing valve that corresponds to the line you want to sanitize;
discharge the residual pressure from the syrup line.
6 -
Insert the suction tube (with the coupled connector) in a bucket containing clean warm water only.
7 -
Power the pneumatic pumps with a pressure of approximately 1.4 bar (21 psi - 0.14 MPa), so that water
flows through the syrup line and inside the pumps themselves, removing any encrustations and every trace
of syrup from the line.
8 -
Replace the warm water with the detergent solution with concentration level as described above.
9 -
Dispense from the valve until the detergent solution begins to come out; (typically after 15 seconds /
5 mt of python);open the valve for 15 sec and stop for 5 sec: repeat for 4 times, open the valve for 30 sec.
10 -
Repeat points 6 & 7 to rinse the syrup line with clean water
11 -
Replace the warm water with the sanitizing solution described above
12 -
Dispense from the valve until the sanitizing solution begins to come out (typically after 15 seconds / 5
mt of python);
13 -
Once the contact time has elapsed (15-20 min), thoroughly rinse the line with clean water (see points
6 - 7 of this procedure). Check the pH of the output water is the same as that of the input water (use litmus
paper or a pH meter).
14 -
Disconnect the suction tube adapter and connect a syrup BIB. Restore the pneumatic pump supply
pressure to its usual set value (chapter ”4.6” pag. 38), then dispense syrup from the taps until all the water
has been totally eliminated.
