Hlynur Guðnason will give a master's lecture in Master's lecture in industrial engineering today, Monday 17 September at 15-17.

The aim of the project was to analyze the raw materials of icefish trawlers that bring supercooled raw materials ashore on the one hand and icefish trawlers that bring traditional raw materials ashore stored on ice and to analyze the effect of these two methods on raw material processing properties. and how to maximize the value of landings.

The project is twofold, in the first part of the project a study was carried out on the effect of cod cooling on fillet utilization and product division in HB Grandi's processing in Vopnafjörður. In the second part, a statistical analysis is performed on data from HB Grandi's processing in Reykjavík in order to answer how to maximize utilization and quality and minimize the shortcomings of the catch that comes ashore.

The main results of the project are that the type of cooling does not seem to have a significant effect on the fillet utilization of redfish and saithe, as it is largely dependent on the weight and carcass of the fish. Likewise, the type of cooling does not seem to have a significant effect on the defect rate, but the defect rate seems to depend mainly on the weight of the raw material and the condition of the machines. There is a significant difference in the proportion of red fillet redfish fillets between vessels as well as the fillet utilization of saithe according to the age of the raw material when it is processed, and utilization can therefore be maximized by processing the fish at that age if that possibility exists.
