METHOD AND SYSTEM FOR TREATING RIND FORMATION/ COOLING/ DEEP FREEZING - PRODUCTS

摘要

A method for the total or partial freezing of a product (2), i.e. a food product, wherein the product is placed in contact with a refrigerating surface in order to freeze the product on at least one of the surfaces thereof in a treatment container (1), resulting in the use of a vibrating support and a film of cryogenic liquid placed on said support, characterized by the following measures which are carried out: a heated temperature probe (10) is provided in the treatment container just before the exit of said products from the container, said probe being able to measure the temperature in the location thereof; means (4,12) are provided in order to supply the container with cryogenic liquid, said means comprising a proportional valve (12); a unit (11) for the acquisition and processing of data (11) is provided, said unit being able to receive temperature information provided by the probe and being able to act in a retroactive manner if necessary upon the opening rate of the proportional valve.
