Utilization of geothermal energy for drying fish products

This paper is about industrial uses of geothermal energy for drying of fish products. Drying is an ancient method for preservation of foods, the main purpose of which is to increase the preservation time. For drying, an external source of energy is needed to extract water. In this paper an emphasis is placed on drying fish and associated processes, and how geothermal energy can be used to substitute oil or electricity. The Icelandic Fisheries Laboratories have been experimenting with different methods of drying, and several drying stations have been designed for indoor drying of fish products. Today there are more than a dozen companies in this country which are drying fish indoors using for that purpose electricity and/or geothermal energy. Further possibilities are available when fish processing plants are located in geothermal areas.
