9.2.5 POSITIVE HARD CHILLING WITH CORE PROBE and subsequent storage
The chilling cycle with core probe and subsequent storage consists in three phases:
►
1st phase: Hard chilling cycle
(Room temp. setpoint -20°C; Core probe temp. setpoint 15°C)
►
2nd phase:
Soft chilling cycle
(Room temp. setpoint 0°C; Core probe temp. setpoint 3°C)
►
3nd phase:
Storage
(Room temp. setpoint 2°C)
After completing a phase, the blast chiller automatically switches to the next one.
- Make sure the blast chiller is in “ON/STAND-BY” mode, that the keyboard is not locked (chapter
