Delfield T24C, T20C, T40, T5, T14D Hard Blast Chilling by Temperature, Hard Timed Blast Chilling

5.4 HARD BLAST CHILLING BY TEMPERATURE

• Press push-button		HARD			to select the temperature
		+38ο 3 (relative LED lights up), then press push-button 5
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.
• Display		15 indicates the maximum blast chilling time (starting temperature to end of the blast
chilling temperature - factory setting - 90 minutes).

•The temperature measured by the core probe is shown by display 16 οC .

•The instrument timer starts the countdown of the maximum blast chilling time as soon as the temperature measured by the core probe falls below the temperature of +149°F / +65°C (the dot at the bottom right of

display 15 flashes).

•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 around +32°F / 0°C (LED on push-button 3 on). The first stage of the cycle is completed when the core probe detects a 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 chilling temperature (+38°F / +3°C) has been reached as signalled by an intermittent beep for a minute. During the beep, LEDs 13 and 14 flash.

Display 16 οC indicates the temperature inside the cell, while display 15 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 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	HARD	(relative LED lights up), then press push-button 5		to
	+38ο
select the “timed” mode (LED 5B on). Display 15			shows the maximum chilling time (set by default
to 90 minutes).
To modify this time, press push-buttons 7		and 8	(time in minutes).

•To set the time of the first negative temperature stage, press push-button 3

for display 15 to show the flashing value.

+38

HARDο for five seconds, then wait
