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 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.

Introduction
There are four main programmes that you will need to use your Blast Chiller.
Soft Chill- for the safe chilling of delicate products.
Hard Chill Time - For general purpose chilling based on time.
Hard Chill +-. This program is for specialist chilling only and is not recommended for normal use.
Hard Chill Temperature - For general purpose chilling using the food probe.

Display Set Point: Press the SET key whilst in the HOLD Mode will display the set point for 5 seconds.
Modify Set Point: Press and hold the SET key for 2 seconds. The SET point will be displayed and the LED’s
of the first and third digits will blink. To change the value, press the UP key to increase the value or the DOWN key to decrease. To store the new value either press the SET key or wait for the controller to return to displaying air temperature.
Manual Defrost: Press and hold the DEFROST/UP key for 2 seconds to initiate a manual defrost.
Starting the cycle: Press and hold the START/STOP key for 3 seconds.
Temporarily Stopping the Cycle:
Press and release the START/STOP key.
The condensing system will stop and the message “Stb” will be displayed.
To restart the cycle press and release the START/STOP key for the cycle to continue from the point it was interrupted. Alternatively the cycle will restart automatically after the time set in parameter PAU (see parameter list on page ).

Program function and operation.
Each of the programs is divided into 3 phases of operation.
Phase 1: Hard Chill. Phase 2: Soft Chill. Phase 3: Freezing Cycle.
For each phase there are 3 parameters.
IS1 (iS2, iS3): operation controlled by the Food Probe. RS1 (rS2, rS3): set point for the room Temperature Probe for each phase. Pd1 (Pd2, Pd3): The maximum time duration for each phase. Hds: hold phase set point at the end of the whole cycle.
There are also 2 parameters relating to defrost. These are dbC = Defrost Before cycle, dbH = defrost before hold (at the end of the cycle).
