6.2.2.2 CONSISTENCY CALIBRATION
I FRIGOMAT electronic batch freezer series VIBEGEL are equipped with an electronic
card with a sophisticated microprocessor that enables to control the ice-cream consistency
through the acknowledgement of different parameters, such as the agitator motor power
consumption. During the batch freezing cycle, the machine display visualises numeric
values between 0 and 240, which are directly proportional to the ice-cream hardness.
Each machine is tested and calibrated by FRIGOMAT with standard mixtures and with an
agitator motor power consumption referring to a hardness value of 240. Such value is
reported on the test sheet supplied with the machine (see: AGITATOR AMPERE
@SET240 on the test sheet); this calibration can normally satisfy a wide range of requests.
It is possible to adjust the batch freezing consistency value for any particular requirement:
this operation shall be carried out by authorised skilled technicians only who shall use a
clamp meter with suitable accuracy and CARRYING CAPACITY.
To set the consistency, it is necessary to remove the panels and act on the electronic card
inside the electric box while the machine is under voltage. Each operation shall be carried
out very carefully and in conformity with the safety regulations in force.
Follow the instructions below to perform the consistency calibration:
1. Disconnect the machine and remove the electrical box from the rear part. Then remove
the cover.
2. Connect to the OMEGA-card the push panel of the model VIBE, code ….
3. Find the current transformer power wire (identified with L1 – see electric diagram) and
connect it to the clamp meter. This way the agitator motor power consumption can be
measured.
4. Fill the cylinder with the maximum amount of ice-cream mixture.
5. Power up the machine.
6. Program on the selector the SET 6 (the display will show 240) and press the
PRODUCTION.
7. While the machine is working, press key P1 on the electronic card in the electric box.
To enter in the “consistency adjustment” mode, the STOP, CLEANING, DELIVERY and
SEMI-AUTOMATIC pushbuttons light up and the display visualizes the consistency
numeric which increases while the machine is working.
8. Press pushbuttons STOP (
↓
) and CLEANING (
↑
) to respectively increase and
decrease this number and adjust the consistency.
9. Once the desired consistency has been reached, the expected value can be read on
the clamp meter; press STOP (
↓
) and CLEANING (
↑
) until the number 240 appears on
the display; the machine will then signal that ice-cream is ready.
10. Press DELIVERY (
↔
) to store the setting which has just been carried out. The
machine is now correctly programmed.
