Control of quick freezing tunnel used in food industry involves prediction of final temperature of articles passing through it based on thermodynamic and physical characteristics

摘要

Method for predicting the temperature of articles (P) passing through the chamber (2) of a cooling installation that uses a coolant (4). The method involves predicting the temperature of the articles leaving the chamber. The prediction is based on characteristic operating quantities of the chamber, the thermodynamic and physical characteristics of the chamber and the thermodynamic and physical characteristics of the articles. An Independent claim is also provided for a corresponding device for predicting the temperature or articles being cooled and or frozen in a cooling chamber and an installation for cooling or freezing articles.
