Introduction.

Cook Chill Operation.

Blast chilling is a process to reduce the temperature of cooked food by swiftly arresting the cooking process, locking in its colour, flavour, texture and nutritional value. Department of health guidelines state that to safely blast chill food the temperature must be reduced from +70°c to +3°c within 90 minutes.

Pre Chill ensures the correct cabinet temperature in the unit before chilling commences therefore improving the chilling performance.

Program 1 Soft Chilling.

Soft chilling is the process of rapid but gentle chilling of food.

This cycle brings down the food temperature to +3°c in no more than 90 minutes without the air or food temperature going below +2°c.

This prevents large ice crystals forming therefore maintaining the texture, consistency and appearance of food such as vegetables, rice, pasta, custard and fruit with no dehydration or cell damage.

Program 2

Hard Chilling Time.

Hard chilling is the process of general purpose chilling using time.

This cycle brings down the food temperature to +3°c in no more than 90 minutes and is ideal for chilling meat pies, lasagne, pasta and individually portioned meals. The air temperature for this process goes down to -15°c for the first 70 minutes of the cycle, to extract the maximum amount of heat from the product quickly. The air temperature then increases to +2°c for the final 30 minutes of the time to reduce surface damage and ensure quality.

Program 3

Hard Chill +

This program is for specialist chilling only and not recommended for normal use.

Program 4

Hard Chilling Temperature.

Hard chilling is the process of general purpose chilling using the food probe.

This cycle brings down the food temperature to +3°c in no more than 90 minutes and is ideal for chilling meat pies, lasagne, pasta and individually portioned meals. The air temperature for this process goes down to -15°c for the first 70% of the cycle, to extract the maximum amount of heat from the product quickly. The air temperature then increases to +2°c for the final 30% of the time to reduce surface damage and ensure quality.

Longer Term Storage – ‘Hold’ Mode (Conservation)

Upon the completion of the blast chilling cycle the controller will automatically enter the ‘Hold’ mode. This will either be because the selection set time has elapsed or the product core temperature has been achieved. When the hold period commences an alarm will sound for a period denoted in the service operating parameters.

The controller will determine the temperature to be maintained during the hold phase based on the chilling or freezing cycle that has been completed. If a soft or hard chill has taken place the controller will maintain an air temperature of 2°c, if a freeze program is completed the air temperature of -21°c will be maintained.

The hold mode is principally intended as a temporary storage facility offering the operator flexibility until the product can be unloaded into a longer term storage units at the correct storage temperature. On occasion this hold period may become extended to operate overnight or to provide emergency refrigeration backup. In such instances defrosting would automatically occur as necessary.

Operation

When mains electrical power is first applied to the controller it will carry out a self-test function - - - for

approximately 3 seconds, after this the cabinet air temperature will be displayed.

To start, select the program required by pressing the program mode button (1, 2, 3,4), the LED for that mode will

illuminate, press and hold start key for three seconds to start the program. The display will show the program time.

The compressor may pause before starting at the start of a cycle to prevent short cycling of the condensing system and is normal.

When the time or temperature is achieved the machine will go in to the Hold mode with the sounding of an alarm. To stop the cycle press and hold the start key for 2 seconds, the cycle will be terminated.

Manual Defrost.

When the blast chiller is in hold press the defrost key and hold for 2 seconds to start the defrost. When defrost is complete the machine will revert to the hold temperature.

DEFROST

tdF

Defrost type (not present in the XB350C): (rE= electrical heater; in = hot gas).

dPO Defrost before the holding: no= no defrost; YES= defrost at the start of a holding cycle.

IdF

Interval between defrost cycles: (0.1÷ 24.0; res. 10 min) Determines the time interval between the

beginning of two defrost cycles. (with 0.0 the defrost is disabled)

dtE

Defrost termination temperature (not present in the XB350C): (-50÷50 °C/°F) Sets the temperature

measured by the evaporator probe, which terminates the defrost.

MdF Maximum length for defrost: (0÷255 min) When EPP = no (timed defrost) it sets the defrost duration, when EPP = YES (defrost termination based on temperature) it sets the maximum length for defrost.

dFd

Temperature displayed during defrost: (rt , it, SEt, dEF) rt: real temperature; it: temperature at the start

of defrost; SEt: set point; dEF: “dEF” message

Fdt

Drip time (not present in the XB350C): (0 ÷ 60 min) Time interval between reaching defrost termination

temperature and the restoring of the controllers' normal operation. This time allows the evaporator to eliminate water drops that might have formed during defrost.

FANS

FnC Fans operating mode during the holding phase:

C-n= runs with the compressor, OFF during defrost; o-n = continuous mode, OFF during defrost; C-Y = runs with the compressor, ON during defrost; o-Y = continuous mode, ON during defrost;

FSt Fan stop temperature: (-50÷50°C/°F; res. 1°C/1°F) if the temperature, detected by the evaporator probe is above FSt fans are stopped. It serves to avoid blowing warm air around the room.

AFH Differential for the stop temperature and for the alarm (0.1 ÷ 25.0 °C; ris.0.1°C/1°F) Fans carry on working when the temperature reaches the FSt-AFH value, the temperature alarm recovers when the temperature is AFH degrees below the alarm set.

rEL

Release code (readable only)

Ptb

Parameter code (readable only)

Printer Management

The instrument XB570L can drive the serial printer XB05PR by means of the RS232 output. So temperatures measured during a freezing cycle can be printed.

The internal Real Time clock of the instrument provides time reference.

The “Prt” functions manages the printer by means of the following parameters: Prt: printer presence: (Yes/no) it enables or disables the printer.

itP: printing interval: (0.0÷30.0 min).

PbP: which probe has to be printed: (iP: Only the insert probe; rP: Only the thermostat probe; irP: Insert and thermostat probes; irE: All the probes.

PtH: Printing during the holding phase (yES, no) yES = Printing enabled during the holding phase; no = Printing disabled during the holding phase.

NOTE: Although the controller is capable of several features ie. HACCP recording and output, it is intentional by Foster that these have not been developed to maintain the simplicity of operation for the end user. Therefore these features are not offered or supported.
