5. Refrigeration circuit for industrial freezers
Freezing foodstuffs means reducing their average internal temperature from its initial value of around 20°C to a core temperature of – 18°C, in as short a time as possible. This freezing time has a direct impact on product quality, to preserve their physical and organoleptic properties. In this case, freezing (physical term) is called "deep-freezing" (commercial term).
Depending on the size of the product to be processed, different freezing systems have different technological characteristics. The most common are as follows:
Fluidized-bed systems for small products such as peas, green beans or French fries, with short freezing times of up to 10 min;
straight or spiral conveyor belt systems, for more massive, generally elaborate products such as ready-made meals or cuts of meat, requiring...

Regulations
Pressure equipment regulations
In the past, it was defined by a decree of 1943, subsequently revised in 1960. As part of the harmonization of technical regulations, the European Union has issued a Pressure Equipment Directive (PED) (no. 97/23), which becomes the only rule in force in each member state; for France, the transcription is the subject of a decree and order no. 99-1046 of 13/12/1999.
