7.3 Chocolate spray nozzle maintenance
Each day, at the end of the working cycle use the
dosing pump to pump warm water through the
chocolate feed pipe.
Periodically, and when required, dismantle the
end of the chocolate spray nozzle (Pos.1, Fig.7.1)
to restore its correct operation.
7.4 Doser maintenance
Periodically check the efficiency of the dosers.
Proceed as follows:
1 - Shut-off the compressed air supply;
2 - Slacken the screws holding the doser
retaining bar;
3 - Remove the doser;
4 - Dismantle the doser:
- by unscrewing the bottom ring-nut (Pos.1,
Fig.7.2);
- opening the joining clamp between the
lower and upper parts (Pos.2, Fig.7.2);
- extracting the doser piston shaft
(Pos.3, Fig.7.2).
With the doser dismantled, check the
efficiency of the O-rings (Pos.4-5, Fig.7.2)
on the stem.
If worn, ice-cream will leak from the top of
the doser.
5 - Wash using the recommended products (see
washing table) and reassemble.
