Tittel

Discretized model of a fish freezing tunnel in Modelica

Sammendrag

Freezing processes are highly energy demanding and increased efficiency are both economically and environmentally beneficial. However, industrial freezing plants are often not optimized regarding energy efficiency. Operating conditions, such as the heat flow from the products, change during the process and air flow and temperature distribution throughout the tunnel is uneven, resulting in different freezing times for products at different locations. Measurements at plants are hard and expensive to conduct, so in order to be able to predict fish temperatures and freezing times at any location within the tunnel, a discretized dynamic model of an air blast freezing tunnel for fish, allowing different air velocities at different heights, has been developed. The simulation results have been compared to measurements of air and product temperatures at an industrial freezing plant and CFD simulation of the air velocity from a previous study. The results show that the product temperatures can be well predicted with the simulation program.
