6.1.4 Chocolate spray pump equipment
A frame with wheels (Pos.1, Fig. A.5) supports
the thermo-regulated chocolate tank (Pos.2, Fig.
A.5) by means of a thermostat (Pos.3, Fig. A.5 ).
The inside temperature of approx 34¡ to 37¡ is
ensured by the water contained in the jacket/air
space which is heated by electrical resistances
(Pos.4, Fig. A.5).
The flow rate of the positive-displacement pump
can be adjusted by loosening the screw with the
wrench and by turning the ring nut (Part.5
Fig.A.5) anticlockwise to increase the stroke of
the pneumatic actuator, or clockwise to decrease
it.
Tighten the screw with the wrench at the end of
the operation.
During production, the tank has to be filled
manually.
To activate the chocolate heating, press the
“chocolate tank heater” button A1 (See Chap.5).
For details on how to start the station on a manual
cycle, proceed as shown in Charter 5.
The chocolate return route to the tank is necessary
because the pipes are not heated; hence the re-
cycling bypass prevents the chocolate from
stopping and solidifying inside the pipe. This is
achieved by carrying out continuous pumping
cycles whose ON/OFF intervals can be set in the
CHOCO SPRAYER page (See Chapter 5 for
details). This cycle is carried out even when the
machine is not operating. To turn off the valve
which controls the pump, set the PUMP OFF
TIME value to zero.
During production, the dosing volume is regulated
by increasing or decreasing the travel of the
positive-displacement pump and by regulating
the opening times of the spray nozzles through
the programmer.
Time adjustment is achieved by modifying the
degrees on the related cam.
To perform such an adjustment refer to and
compare with 5.2.1 Setting the work
parameters.
The chocolate is fed in the cone wafers by means
of sprayers.
The incoming chocolate is atomized by the action
of compressed air which is sent to the appropriate
connection.
The customer is responsible for sterilization of
the line downstream of the filter.
WARNING
The water in the air space must be heated at least
half an hour before use. See Chapter 5.
