OPERATION

GENERAL USE OF THE CABINET

Blast chiller & freezer quickly reduce the core temperature of the products, whether they are cooked or fresh, conserving their fresh texture, hygiene and quality, whilst reducing the risk of bacteria generating.
The traditional method of storing cooked food has always been to leave it to cool naturally until it reaches a suitable temperature to store in the refrigerator.
During the period when the core temperature falls from +65ºC and +10ºC, the food will lose a lot of its natural characteristics, such as moisture, consistency, aroma and color. These blast chillers & freezers are designed to reduce the time period for this critical change in temperature.

• The storage cabinet is designed to fit two kinds of pans

  • GN 1/1 pan
  •  400×600 EN pan
    When blast chilling always use metal or foil containers which are good conductors. Plastic or polyurethane containers insulate the food from the cold air. When chilling unportioned food we recommend the use of the appropriate gastronorm tray or similar.

• Loading food
  Attention： Make sure that the unit drops down to desired temperature before loading the  unit with food

  • The maximum temperature of food entering the Blast Chiller/Blast Freezer must not exceed
    + 80°C (176°F). Regulations state that product should be placed in the Blast Chiller/Blast Freezer within 30 minutes from completion of cooking.

  • The packaging of food and the way in which it is loaded or placed within the equipment can have a significant effect on the time within which the temperature can be reduced to the require level and the amount of food which can be processed in each chilling or freezing batch.(Maximum food thickness 50mm).

• It is important to insert the probe correctly.
  The needle of probe should be inserted until the point reaches the center of the foodstuff.

OPERATION INSTRUCTION FOR TEMPERATURE CONTROLLER
The unit has been created for fast chilling or freezing goods according to international food safety standards.
There are FOUR types of cycles:

•  The CYCLES: Cy1, Cy2, Cy3, Cy4 are pre-set according to the most common cycles used in food -safety applications; the user can select one of them according to his own requirements and modify it as he wants.
•  Any cycle can be manually terminated before the normal.
• Any cycle can use the insert probes (up to 3), they measures the internal temperature of the product.
•  During the Cycle there are no defrosts and the fans are always on, a defrost cycle can be done before any freezing cycle.
• The cycle is divided up to 3 phases completely configurable by the user.
• Each instrument is provided with an output for remote display XR REP, which shows the temperature of cabinets or goods.
•  The controller is provided with internal real time clock and can be connected to the printer. This means that a report, which includes all the main features of cycle, can be printed: start and end of the cycle, length of the cycle, logging of the temperature of the cabinet and goods.

HOW A CYCLE IS DONE

1. Every programmable cycle Cy1, Cy2, Cy3 or Cy4 can be divided into up to 3 phases usually called:
   • hard chill
   • soft chill
   •  freezing cycle
2. For each phase there are 3 parameters.
   iS1, (iS 2, iS 3): Set point related to the insert probes that stops the current phase.
   rS1, (rS2, rS3): set point of the room temperature for each phase.
   Pd1, (Pd2, Pd3): the maximum duration time for each phase.
   Hds : set point of the hold phase at the end of the whole cycle.

HOW TO USE THE INSERT PROBES.
By means the insert probe, the internal temperature of products can be checked. This measure is used to end the various phase of the cycle. A special internal function detect if the inset probe is not used, in this case the cycle is made by time
EXAMPLE OF A BLAST CHILLER CYCLE.
The following drawing explains how a Blast Chiller cycle can be done.
First phase: “Hard chill”.

It is normally used to fast chill hot foods. E.g. from 80°C / 170°F to 20°C / 70°F.
During “Hard Chill”, both compressor and fan are always on until the rS1 temperature is reached. At this point compressor is turned on end off so as to keep the temperature of the room at the rS1 value. “Hard Chill” ends when the temperature measured by the 3 insert probes reach the iS1 value.  Second phase: “Soft chill”.
The Soft Chill starts when the Hard Chill ends. It is used to prevent thin layer of ice from forming on the product. The Soft Chill lasts until the temperature measured by the 3 insert probes reach the set point iS2 (usually 4 or 5°C).
During Soft Chill the temperature of the room is regulated by the ambient probe with the set point rS2 (normally at 0 or 1 °C / 32 or 34°F). When the box temperature reaches the rS2 value compressor is turned on end off so as to keep the temperature of the box at this value.
Third phase: “Freezing cycle”.
Freezing Cycle: used to fast freeze foods. The Freezing Cycle starts when the Soft Chill ends. During the “Freezing Cycle” both compressor and fan are always on until the rS3 temperature is reached. At this point compressor and fans are turned on end off so as to keep the temperature of the room at the rS3 value (normally some degrees below iS3).Freezing Cycle end when the temperature measured by the 3 insert probes reach the iS3 value
End of the Blast Chill cycle and starting of the Hold Mode.
When one of the three insert probes reaches the iS3 value the values End followed by the i1P or i2P or i3P are shown on the display.
Cycle ends when all the probes have reached the iS3 value. A signal is generated buzzer and alarm relay is turned ON, the display shows the message “End” alternating with the room temperature.
The alarm automatically stops after the “but” time or by pressing any keys.
At the end of the cycle the controller can start the “Hold mode” keeping the room temperature at the value set in
HdS parameter.
If HdS = OFF, the machine is turned OFF.
NOTE1: with dbH = yES a defrost is done before the holding phase.
NOTE2: If the end cycle temperature iS3 is not reached in the maximum time Pd1+Pd2+Pd3 the instrument
keep on working, but the alarm message “OCF” is given.
