Abstract
A plant for continuously cooling foodstuffs includes a container suitable to receive such foodstuffs continuously moved by a movement member and refrigerant apparatus for cooling such foodstuffs during the movement thereof, the movement member being a pump; the plant includes a spiral duct preferably arranged around the container wherein the pump continuously directs and moves the foodstuffs to be cooled and in which there is directed a cryogenic fluid, along at least two different turns of the spiral duct there being arranged apparatus for injecting of the cryogenic fluid.
Claims15
A plant for continuously cooling foodstuffs comprising
- a container suitable to receive foodstuffs continuously moved by a movement member
- refrigerant means for cooling such foodstuffs when moving them, the movement member being a pump,
- a spiral duct wherein said pump continuously directs and moves the foodstuffs to be cooled, along said spiral ductthere being arranged the refrigerant means which direct a cryogenic liquid gas into the spiral duct and on the continuously moving foodstuffs,
- such spiral duct having an inlet endwhich receives the foodstuffs and an outlet end at the aforementioned container,
- said foodstuffs remaining at contact with said cryogenic gas in the spiral duct up to the inlet in the container,
- said spiral duct comprising a plurality of turns arranged superimposed on parallel planes,
- said refrigerant means comprising injector means suitable to introduce the cryogenic liquid gas into the spiral ductso thatthe cryogenic liquid gas comes into contact with the moving foodstuffs,
- said injector means being arranged on a plurality of consecutive turns of said spiral duct.
