3. ADVICE TO ENSURE EFFICIENT APPLIANCE OPERATION

3.1 SHUTDOWN PROCEDURES

In the event of emergency, shut down the appliance by swit­ching off power at the main panel, by means of the knife
switch or by removing the plug from the power socket.

3.2 OPERATING TIPS

Before starting up the appliance, clean the inside of the cell
thoroughly.

3.2.1 Pre-cooling

Before using the appliance for the first time, or after a pro­longed period of disuse, pre-cool the cell by running an
empty cycle until the set operating temperature has been
reached.
To ensure optimal performance without any alteration to
food quality:

• arrange food products in such a way as to favour the circula­tion of cold air throughout the cell;

• open the door as little as possible.

3.2.2 Loading the appliance

a) Ensure that foods to be chilled and/or frozen are separate

and do not have a thickness greater than 50-80 mm. Do not
load the appliance beyond the quantity recommended by
the manufacturer.

b) Ensure that there is sucient clearance between trays to ena-

ble free air circulation.
If the appliance is not completely full, distribute the trays and
foods evenly throughout the available space.

c) Position trays inside the tray compartment as far as they will

go, as close as possible to the evaporator.

d) Position the core probe at the centre of the largest product

or food item; make sure that the tip of the probe does not
protrude or touch the tray.
The probe must be cleaned and sanitised before each new
cycle (operation) to prevent inadvertent contamination.

e) Avoid covering the trays and/or containers with insulating

covers or film. The more the product is insulated, the more
time is required for chilling or freezing.
Trays must be packaged when the product has been chilled,
before being placed in storage.

5.4 USB DATA RECORDER (OPTIONAL)

• The USB data recorder will register into a .txt file all the data
during the cycles of the machine: Blast Chilling or Freezing
and also during conservation phase.

• The data is registered every minute and will include:

- Date and time

- Cabinet Temperature

- Core probe Temperature

- Type of Cycle

- Start and Stop of Cycle

- Door openings

- Alarms

• The data is constantly stored on the internal recorder, and
can be downloaded anytime from the internal recorder in­troducing a USB pen drive into the plug on the machine.

Instructions to download the data

1. Find on the machine the USB plug and insert the USB pen
drive

2. IMPORTANT: wait until the led of the pen drive stops fla-
shing, which means that all the data is recorded on the pen
drive.

3. Extract the pen drive

4. On the pen drive you will find a file named log00n000001.txt
which is a text file, delimited with “;” (semicolon).

• The best way to see the data on the file is using Microsoft
Excel, following this sequence:

- Launch Microsoft Excel

- Go to “open file”

- Select “text file” on the type of file

- Open the file registered on the pen drive

- Select “Delimited” file

- Select as delimitator the semicolon “;”

• As an alternative you can open the file with a normal text edi­tor

• Every time you insert the pen drive, a new log file will be ge­nerated, with a progressive number (log00n000002.txt,
log00n000003.txt, log00n000004.txt, etc).

• Every file generated will contain the complete historical data
recorded, up to the moment of insertion of the pen drive. So
every time the file is bigger.

• As a consequence, the time to save the file on the pen drive
(see point 2.) will increase from some seconds to several mi­nutes, depending on how much data is stored on the recor­der. IT’S VERY

WAIT UNTILL ALL THE DATA IS RECORDED ON THE PEN
DRIVE BEFORE REMOVING IT, WAITING UNTIL THE LED ON
THE PEN DRIVE STOPS FLASHING.

When updating data: time, day, and year on the board of
the computer, it’s necessary to remove and then restore the
power supply to allow the change data is also stored in the
USB recorder.

6 GREAT TECHNOLOGY AND PROCESS VALUE

• Putting freshly cooked food directly in the storage unit is a
mistake! Cooling is static and not very powerful, the chilling
time is too long and bacteria develop rapidly in large quan­tities.

• Only by using a chilling system with forced ventilation heat
exchange can we be sure that we are preserving the high
initial quality of the food: its appearance, colour, flavour and
aroma.

• Cold, like heat, if not properly managed and metered can vi­sibly damage food.

• Since every food has its own characteristics, the use of a spe­cific chilling system every time is important.
Our equipment is characterized by its versatility and the avai­lability of several functions in the same machine.

- Quick “Soft” blast chilling for delicate products with a redu­ced thickness.

- Quick “Hard” blast chilling for all dense products, in large
pieces or packaged.

- Quick freezing.

6.1 "SOFT" BLAST CHILLING

From +70°C to 3°C at the product core within a maximum of
90 minutes, with air temperature that is always and only po
sitive 0/+2°c, avoiding any type of freezing of the surface
of the food.

6.2 "HARD" BLAST CHILLING

From +70°C to +3°C at the product core within a maximum
of 90 minutes, with variable chamber air temperature auto
matically controlled by the computer. This system allows for
a 2530% time savings in comparison to the "soft" cycle!

6.3 QUICK BLAST FREEZING

function available only in certain models
From +70°c to 18°c at the product core as quickly as possibly
and within at most 4 hours, with a chamber air temperature
of 40°c. Rapid cold penetration prevents the transformation
of water into macrocrystals, thus not ruining the consistency
and integrity of the food.

Each cycle can be manually controlled using the timer or au
tomatically controlled with the food probe. The automatic

storage function at the end of the cycle and the automatic
and manual defrosting cycles complete the exceptional

blast chiller accessories.
