3 - FOOD PROBE

The food probe or hat pin probe, has a resolution of 0.1^ and an operating range from -49.9^ to +99.9^ . The temperature detection is carried out on a single point in correspondence of the central part of the probe body. To ensure proper operation and accurate detection of the temperature for the management of cycles, the probe must be inserted up to the product core.

4 - OPERATING CYLCES

The blast chiller can manage the following operating cycles :

1- Automatic blast chilling
2-Manual blast chilling
3-Automatic shock freezing
4- Manual shock freezing

5-

Thawing

6-

Defrosting

7- Export HACCP
8-Sterilization (optional)

Please note that the blast chilling or the shock freezing cycles are designed to rapidly cool the food and the difference between the two cycles is determined by the final temperature you want to obtain to the heart of food:

• BLAST CHILLING positive = final positive temperature in the around of +3°C
• SHOCK FREEZING negative = final negative temperature in the around of -18°C

The defrosting cycle, has the function of bringing a food from negative temperatures to positive temperatures. To be noted that the positive air temperature is not obtained by heating, but by air circulation within the terms required by the HACCP.

The machinery has an innovative cell PRE-COOLING function, with an indeterminate duration at the discretion of the user who will decide when to start the blast chilling or the shock freezing cycles. Bringing the cell air temperature to a much lower temperature than the surrounding environment before starting any cycle, allows not only to reduce the total cycle time, but also to obtain a correct and uniform micro-crystallization of the food resulting in a reduced product weight loss and guaranteeing the organoleptic characteristics similar to the fresh product.

Following are the main characteristics for each single operating cycle:

1- AUTOMATIC BLAST CHILLING : Automatic cycle with temperature detection exclusively through food probe
2- MANUAL BLAST CHILLING: Manual cycle adjustable for the following values:

time : cycle duration and cell air temperature

temperature : product final temperature and cell air temperature

3- AUTOMATIC SHOCK FREEZING : Automatic cycle with temperature detection exclusively through food probe
4- MANUAL SHOCK FREEZING: Manual cycle adjustable for the following values:

time : cycle duration and cell air temperature

temperature : product final temperature and cell air temperature

5-THAWING: Manual cycle adjustable for the following values:

time : cycle duration and cell air temperature

temperature : product final temperature and cell air temperature

6- DEFROSTING: Automatic cycle only with AIR with time set to 600 seconds with the aim at cleaning the evaporator.
7-EXPORT HACCP: Using the USB door on the front panel on the right side of the CONFIRMATION button, it is possible to export the HACCP data approximately for the operations of a complete month (120 hours of operations).
