Industrial energy storage - State-of-the-art report with focus on thermal energy storage
This report presents overview and state-of-the-art on industrial energy storage in industries. The report presents an overview of energy-storage technologies suitable for integration in industrial production and manufacturing processes. Furthermore, we present and compare motivations for storing ene...
Potential for steam regeneration in Norwegian industry
Three dimensional modelling of water and salting kinetics in dry-cured ham for improved quality control
Superior quality and reduced salt content is of major importance in the production of dry-cured ham, which is a product with long traditions in several countries worldwide. The production is time-consuming and includes salting, resting and months of drying and ripening at low temperatures. The effec...
Energy use in Norwegian non-Residential buildings : building regulations, calculations and measurements
Energy use in Norwegian non-residential buildings: building regulations, calculations and measurements
Heat pump drying : use of ambient air as enery source for cooling
The concept of heat pump drying was investigated on the example of an industrial system for clipfish by a dynamic object-oriented model approach. The climatic conditions at the production facility are considered as additional energy source for the de-humidification of the drying air. The annual savi...
Challenges of the usage of ultra-low temperatures for fish freezing and storage
The physical states of frozen fish (muscles and oils) was analysed in the temperature range between -150.0 and 20.0 °C. The information of the glass transition temperature, the end of freezing point, the amount of unfrozen water, the amount of liquid fraction of oil was obtained by the method of Dif...
Simulation of a fish freezing tunnel using Modelica
The problem of energy consumption during freezing of pelagic fish in an air blast freezing tunnel was investigated. Measurements from a freezing plant were compared with the results from a simulation model, and the results of the comparison show that the required freezing time can be reasonably well...
Chilling of salmon in refrigerated sea water
The optimization of the refrigeration process was based on existing systems for chilling of Atlantic Salmon in refrigerated sea water (RSW). Two methods (continuous and interrupted) chilling of salmon in RSW were investigated. Significant increasing of brine flow for fish chilling from 150 to 600 L ...
