Hard Timed Blast Chilling; Blast Freezing By Temperature - Welbilt Delfield CV5E Original Instructions Manual

Section 4
temperature of 68°F / 20°C in the product core.
- The blast chilling phase ends only when the core probe
(inserted in the product core) indicates that the set blast
chillling temperature (38°F / 3°C) has been reached as
signalled by an intermittent beep for a minute. During the
beep, LEDs 13 and 14 will flash.
Display 15 indicates the temperature inside the cell, while
display 14 shows blast chilling time reset to zero.
- The alarm (ALL 14) and conservation functions cut in
with relative indicators in the same way as for timed soft
blast chilling.
- Press push-button 6 to set the appliance to STOP status
(relative LED switches off ), ready for a new cycle.
IMPORTANT
HARD blast chilling affords a considerable reduction
in working time, and is particularly suited to foods with
a high fat content, for a large pieces or for packaged
products.
SOFT chilling is recommended for delicate and finely
chopped products, such as vegetables, mousses, etc..
IMPORTANT: During chilling or shock freezing by core
sensor it's possible to read:
- The evaporator temperature by pressing push button.

5.5 HARD TIMED BLAST CHILLING

- To select this cycle, press push-button 3 (relative LED
lights up), then press push-button 5 to select the "timed"
mode (LED 5B on). Display 14 shows the maximum chilling
time (set by default to 90 minutes).
To modify this time, press push-button 7 and 8 (time in
minutes).
- To set the time of the first negative temperature stage,
press push-button 3 for five seconds, then wait for display
14 to show the flashing value.
The time setting (in minutes) can be modifided by means
of push-buttons 7 and 8. Press push-button 3 again to
return to standard display.
- Start up the cycle by pressing push-button 6. LED 5B
and push-button LEDs remain on and LEDs 13 flash
throughout the cycle.
- Internal cell temperature is shown on display 15.
- Once the cycle has been started, the appliance operates
initially with an air temperature below 32°F / 0°C (LED on
push-button 3 flashes), then with temperatures arounf
Part Number: 9294045 07/19
32°F / 0°C (LED on push-button 3 on). For example: HARD
timed chilling cycle 90 minutes. First stage of 40 minutes
with negative air temperatue. Second cycle stage or 50
minutes with air temperature around 32°F / 0°C.
- When the maximum chilling time has counted back
to 0, the chilling cycle is completed and the appliance
automatically switched to the set posoitive storage
temperature for an indefinite interval.
- LEDs illuminate and the beep is activated when the cycle
is finished (as in the temperature chilling cycle). The same
applies for the storage function.
- Press push-button 6 to set the appliance to STOP status
(relative LED switched off ), ready for a new cycle.
IMPORTANT: During chilling or shock freezing by time it's
possible to read the evaporator temperature by pressing
push button.

5.6 BLAST FREEZING BY TEMPERATURE

- To select this cycle, press push-button 4 (relative
LED lights up), then press push-button 5 to select the
temperature mode (LED 5A on). Insert the core probe into
the core of the product to be chilled.
- Start up the cycle by pressing push-button 6. LED 5A
and those relative to the push buttons pressed illuminate
throughout the cycle, while LEDs 13 flash.
- The appliance proceeds to operate in the same way as
that described for the positive chilling cycle. During this
cycle the compressor operates in continuous mode to
enable the appliance to reach the cycle end temperature
in the shortest time possible (default temperature at
product core is set at 0°F / -18°C). Maximumm freezing
time is 240 minutes.
- The alarm (ALL 14) for excessively-long freezing and
conservation functions cut in with relative indicators in
the same way as for timed Soft blast chilling. The factory
setting for negative storage temperature is -13°F / -25°C.
- LEDs illuminate and the beep is activated when the cycle
is finished (as in the soft chilling cycle by temperature).
The same applies for the storage function. Press push-
button 6 to set the appliance to STOP status (relative LED
switches off ), ready for a new cycle.
IMPORTANT: During chilling or shock freezing by core
sensor it's possible to read:
- The evaporate temperature by pressing push button 10.
