Zoom - Cabinets - How to set a special cycle?

In addition to the CHILLING and DEEP FREEZING cycles, the equipment is also capable of managing the following SPECIAL CYCLES, some of which are always available, others are enabled/disabled by the PARAMETERS :

  • pre-cooling
  • manual unbrining
  • fish sanitising (modifying the parameters)
  • ice cream stiffening
  • rod probe heating (modifying the parameters)
  • recipes (programmes with pre-defined cycles)

The SPECIAL CYCLES can be accessed by pressing the AUX key and scrolling along the several cycles available with the MENU and AUX keys. When the desired cycle is selected, confirm with the START key.

 

ACCESS TO SPECIAL CYCLES 

SELECTION OF SPECIAL CYCLES

 

 

 

 

During the execution of the cycle, the display will show the most significant data:

 

when the equipment is in the cooling phase, the compressor icon lights up in the upper left corner;

 

when a recipe is in progress, the blue arrows alternate with the name of the recipe;

 

when an defrost is in progress, the word “Defrost” is displayed above


It is possible to end the cycle at any moment by keeping pressed the START key for 2 seconds.

 

Pre-cooling

 

Before starting a Chilling or Deep freezing cycle it is better to pre-cool the cell and then load the foodstuff.

PRE-COOLING is a refrigeration cycle with infinite duration that can be used before any operation cycle.

 

To access the SPECIAL CYCLES menu, touch the AUX key and select PRE-COOLING.

 

The work SETPOINT set-up screen is displayed; the default value is the

one foreseen by parameter r12 (for more information see page 26), which can be modified using the AUX and MENU keys.

 

The cycle will start by pressing START again.

 

Once the foreseen cell temperature is reached, the buzzer sounds. The cycle continues maintaining the temper- ature reached by the cell until the START key is pressed for 2 seconds, or until the start of a chilling/deep freezing cycle.

 

If, otherwise, the CHILLING and DEEP FREEZING cycles are selected during the execution of a pre-cooling programme, the device will display the settings of the cycles.

 

However, during a PRE-COOLING in progress, the foreseen automatic unbrining is carried out by the machine. in case the electric current is interrupt- ed, eventual PRE-COOLING cycles in progress will be reactivated as soon the current is restored.

 

Manual Defrosting

The machine performs automatically the DEFROSTING cycles (automatic Defrosting). In case of very high ambient temperatures, it is possible to start additional defrosting cycles MANUALLY, besides those normally foreseen.

 

To access the SPECIAL CYCLES menu, touch the AUX key and, using the AUX or MENU key, scroll along all items to select UNBRINING - DEFROST.

 

Press the START key start the unbrining.

 

If the EVAPORATOR PROBE is present and if the conditions to carry out an unbrining are not fulfilled when the START key is pressed, the tab is taken to the SPECIAL CYCLES menu and the unbrining is NOT executed.

The UNBRINING must be executed with the DOOR OPEN.

 

Automatic defrost

 

DEFROSTING is performed MANUALLY with the door open with the door stop.

The DEFROST cycle starts only if the temperature detected by the evaporator probe is below 8°C and stops when the evaporator temperature is above 8°C.

If a pre-cooling cycle is in progress, it is not possible to start a defrost cycle.

 

 

Ice cream stiffening

 

The ICE CREAM STIFFENING cycle is often used in the ice cream and pastry sectors to apply a “thermal shock ” to the products in production. It consists of a continuous deep freezing cycle: once the foreseen temperature is reached, the running of the time set with the parameter r24 will restart upon every door opening.

 

To access the SPECIAL CYCLES menu, touch the AUX key.

Press the MENU key several times to roll along the many items of the menu to select ICE CREAM STIFFENING.

 

       

The activation screen will open, where it is possible to adjust the time of the timer with the keys AUX and MENU.

By pressing START again, the cycle will start and the running of the timer will be signalled with the sounding of the buzzer. The cycle will proceed until the START key is pressed for 2 seconds.

 

Fish sanitising

 

The FISH SANITISING cycle is only available if the ROD PROBE is present.

             

To access the SPECIAL CYCLES menu, touch the AUX key.

Press several times the MENU key to scroll along the several menu items to select FISH SANITISING.

 

       

Confirm touching the START key.

This is a SPECIAL CYCLE composed by the following 3 phases: Negative chilling default value of -40°C (parame- ter r19) until the rod probe reaches -20°C (parameter r20).

  • Maintenance for 24 hours (parameter r21) with the Chamber default value at -20°C (parameter r20).
  • Negative conservation with Chamber setpoint at -20°C (parameter r22).

     

    During the execution of a SANITISING, the device will always display the cell temperature, and according to the phase in progress, the TEMPERATURE to end the chilling or the DURATION of the maintenance.

    The SANITISING cycle starts with the CHILLING phase. When the temperature detected by the ROD PROBE reaches the end of chilling temperature, the device will pass automatically to MAINTENANCE.

    The end of chilling TEMPERATURE (established by r20) represents also the work setpoint during the maintenance. When the time set for the MAINTENANCE has elapsed, the device passes automatically to CONSERVATION.

    The rod insertion test is always carried out at the start of the cycle: if the test is not completed, the buzzer sounds and the cycle is interrupted.

    The cycle can be interrupted in advance by pressing the START key for 2 seconds.

    The start of a FISH SANITISING cycle blocks an eventual pre-cooling cycle in progress.

     

    ANISAKIS

    Anisakis is a parasite infection of the gastrointestinal tract caused by the ingestion of raw or not sufficiently cooked fishery products, containing the Anisakis simplex larvae: if the larvae penetrates into the gastric mucosa they cause a strong abdominal pain, followed by nausea and vomit. In this case, one or two weeks after the infection, they work their way to the intestine and may give way to a serious immunity response, accompanied by intermittent abdominal pain, nausea, diarrhoea and fever or intestinal perforation.

     

    Heating of the rod probe

     

    The function is helpful to speed up theextraction of the rod from the product after a DEEP FREEZING cycle.

    The PROBE HEATING must be performed with the door open, the eventual closing of the door with the cycle already in progress does not affect its operation.

     

    To access the SPECIAL CYCLES menu, touch the AUX key.

    Press several times the key MENU to scroll along the several menu items to select ROD HEATING

     

    Confirm with the START key: a screen is displayed indicating that the cell door must be opened.

     

    Confirm touching the START key.

     

    The heating time OF THE ROD PROBE is variable and depends on the setting of parameters u8 and u7 (see page 31). If it is desired to interrupt the function in advance, keep the START key pressed for around 2 seconds.

    At the conclusion of the function, the buzzer sounds for one second and the display returns to the principal page - Home.

     

    Recipes

     

    The RECIPES are programmed ready to use and stored at the Builder’s plant, each of them designed to process several kinds of food pieces (ex. Red meat, Cream, etc...).

    7 pre-inserted programmes are available, ready to use and offering a series of optimised cycles according to the food piece varieties. During the programming phase, parameter P3 is set to 0, the use of the rod probe is disabled; therefore the RECIPES requiring this probe are not viewed.

     

    ATTENTION:

    These 7 recipes can be modified before the start of the cycle, but cannot be saved nor overwritten.

     

     

    To access the SPECIAL CYCLES menu, touch the AUX key.

    Press several times the MENU key to scroll along the several menu items to select PROGRAMMES.

     

    Confirm with the START key.

    With the AUX and MENU keys, select the recipe that mostly fulfils its own requirements. If needed, the default parameters of the recipes can be modified

    (see the table below), but the changes made will be temporary, while the Builder’s recipes cannot be permanently changed, cancelled or overwritten.

     

    Confirm touching the START key.

     

    Additional recipes

     

    In addition to the 7 standard recipes (unchangeable), the device makes available another 20 programmes (from P1 to P20) that can be applied by the user to save the settings of an own recipe.

    The other 20 programmes are listed just after the 7 pre-set recipes and are identified by three dashes (- - -) that indicate that the position is empty.

    At the moment when the settings of recipe are stored, the letters (Px) will appear automatically, depending on the position where they are saved.

    To save or overwrite one of the 20 recipes proceed as follows:

     

    Press several times the MENU key to find the position of the desired point to save the recipe.

    Confirm with the START key.
