A method for determining the operating parameters of a system for cooling articles. The temperature of the articles, as they leave a chamber, is predicted. The prediction is made on the basis of operating parameters of the chamber, thermodynamic and physical characteristics of the chamber, and thermodynamic and physical characteristics of the articles. The method may be used to determine the operating parameters for food freezing tunnels.

Method for determining the operating parameters of a system comprising a cooling chamber

A plant for the treatment of food product. The plant comprises an apparatus for cooling food products by bringing the products into contact with a cryogenic fluid, a conveyor for introducing the products into the apparatus and for extracting the products from the apparatus, and a detector which determines at least one of (i) a value representative of the quality and (ii) the quantity of products treated by the apparatus. The detector comprises a camera suitable for producing a digital image of a section of the conveyor intended for transporting the products, the digital image revealing the products carried by the section of the conveyor, a data processing unit which includes an image processor suitable for determining the at least one of (i) the value representative of the quality and (ii) the quantity of products treated by the apparatus from the digital image, and a measuring device which measures the quantity of cryogenic fluid with which the products are brought into contact, connected to the data processing unit, wherein the data processing unit computes the temperature of each product leaving the apparatus depending on the value representative of the quantity of products treated and on the measured quantity of cryogenic fluid.
