The duration of the blast chilling cycle is determined by reaching the set temperature (temperature mode) or the preset time
(time mode).
During the first stages of temperature mode, the blast chiller monitors the core probe temperature.
If the core is positioned:
▪ In its housing inside the chamber, the blast chiller switches autonomously to timed mode
▪ Outside the chamber, the blast chiller remains in temperature mode
▪ Inside the product, the blast chiller remains in temperature mode.
In case of false positives due to the product and/or the position of the core probe. Check the positioning of the probe, the
characteristics of the product and how it is to be blast chilled.
