Method for chilling foodstuffs contained in a chilling compartment at controllable temperature, and adapted to perform according to an operating procedure comprising the steps of continuously pulling down the temperature inside the foodstuff to be chilled, until a pre-set value (Tf) is eventually reached, provided that the temperature inside said chilling compartment is lower than a pre-set value, and the temperature at the core of said foodstuff is lower than a pre-set value. In addition, before the process is allowed to move on to the final temperature pull-down step, further conditions are defined to ensure that the temperature pull-down pattern and rate inside the foodstuff are complying with the requirements provided for by the applying standards.
