DEVICE AND METHOD FOR CHILLING OR DEEP-FREEZING FOOD PRODUCTS BY IMPACTING JETS

摘要

The invention proposes a device for chilling or deep-freezing by impacting jets which consists of a tunnel comprising a moving belt, at least one plate and preferably at least two plates located parallel to each other on either side of said moving belt, at least one plate, and preferably both plates, being provided with through-holes, and at least one means for injecting a cold fluid, said tunnel having a zone under pressure P1 and a zone under pressure P2, the pressure P1 being greater than the pressure P2, characterized in that it includes means for varying the pressure in the zone under pressure P1 and/or means for cooling the plate or plates down to a temperature below about −80 DEG C, preferably below −90 DEG C and more preferably still below −100 DEG C and for maintaining that temperature; and a method for chilling or deep-freezing food products by impacting jets.
