Abstract: 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.

Abstract: The invention relates to a method for determining thermal profiles of products leaving a cryogenic cooling installation, said method consisting of: a step (18) for determining a validity value and/or a range of validity values for operating parameters of the installation, forming a modulable set of operating parameters; a step (20) for simulating the operation of the installation on the basis of thermodynamic and physical characteristics of the enclosure (2) and the products (A) and on the basis of regulating parameters of the installation, in order to obtain a complete set of operating parameters including regulating parameters and characteristic quantities of the operation of the installation, said simulation step (20) providing a thermal profile of the products (A) treated, which includes at least one temperature at the surface and one temperature at the centre of the products; and a cycle (30) for the automatic repetition of the simulation step (20) for all of the authorised values of the operating parame

Abstract: The invention relates to a method of predicting the temperature of articles (P) passing through the chamber (2) of a cooling installation using a coolant (4), said method comprising a step whereby the temperature of articles (P) exiting said chamber (2) is predicted. Said prediction is calculated from the characteristic quantities in relation to the operation of said chamber (2), the thermodynamic and physical characteristics of said chamber (2) and the thermodynamic and physical characteristics of said articles (P). The invention is suitable for controlling quick-freezing tunnels for food.

Abstract: 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.
