Improved reefer container for fresh fish - Final report

The main goal of the project Improved refrigerated container for fresh fish was to improve refrigerated containers and procedures for transporting fresh seafood through redesign and testing. The aim is for design improvements to deliver refrigerated containers that reach a more even temperature throughout the transport process. Efforts should be made to achieve satisfactory improvements to refrigerated containers that are used today with simple and inexpensive measures. The consequences of improved temperature control in production and transport processes are increased quality, stability and safety, which at the same time increase the value of the product. Partners in the project were Matís, the University of Iceland, Eimskip Ísland and Samherji. This report describes the main results and products of the project. The results of the project showed that improvements are needed in maritime transport chains and it was shown that improvements can be achieved with simple and low-cost measures. Temperature control for sea transport can be improved by choosing the target temperature and cooling containers that are best suited for transporting fresh fish products. Mapping the heat distribution of refrigerated containers showed variability both in the transport process and in terms of location within the container, but design improvements aimed at forcing airflow within the container resulted in a more even heat distribution. The importance of procedures for loading refrigerated containers and their handling from manufacturer to buyer was also demonstrated.

The purpose of the project Improved reefer container for fresh fish is to use simple redesign and experimental testing to improve temperature control in reefer containers and work procedures of fresh fish products during transport. The design improvements are aimed at producing a reefer with more stable temperature through sea freight and transport. The aim is to get satisfactory improvements with simple and cost effective procedures. Improved temperature control in fish chill chains leads to increased product quality, stability and safety and thereby increased product value. The project was done in collaboration with Matís, University of Iceland, Eimskip Ísland and Samherji. This report describes the main results and products of the project. The results of the project showed that there is room for improvement in sea transport cold chains and with design improvements experiments it was demonstrated that they can be improved with simple and cost effective procedures. The results showed that the temperature control during sea freight may also be improved by selecting the reefer types most suitable for fresh fish transport and selecting different set point temperatures during summer and winter. The mappings of temperature distribution inside the reefers showed spatiotemporal variability and design improvements achieved a more uniform distribution by means of forced air circulation. Field tests demonstrated the importance of correct operating procedures during loading of reefers and their handling from processor to end location.
