GEA Refrigeration Technologies catches freshness on the high seas

To ensure a long life for business relationships as well, GEA Refrigeration Technologies offers effective cooling or freezing technology for every fisherman. The daily routine of fishing work varies considerably. Some fishing boats leave port in early morning and return to harbor on the same day. Others are underway for days on end. To maintain freshness quality in any case, the catch should be immediately cooled to around 0 °C. There are two solutions possible here: the ice is either loaded on board when the ship leaves the harbor, or the ice is produced on the ship as needed.

This all sounds easy enough, but it demands considerable expertise.

Ice machines dedicated to this purpose cool water in a vertical cylinder until it freezes on the inner wall. The ice is scraped off and falls into an ice container located below. The flake ice gained in this way is ideal for use on the high seas, especially since it is “fish-friendly”. Despite the name “flake ice”, the small curved pieces of ice have no sharp corners – which protect the thin, delicate skin of a fish. Flake ice is particularly gentler on fish skin when it has been made from seawater: the salt content makes the ice even “softer”. In addition, this ice is dry, and the fish does not swell. The cool mass has just the right consistency – not too hard and not too liquid – and can be easily handled on a ship, since it can be heaped up.

Cold: yes. Too cold: no. There is a temperature below which fish cannot be stored. Otherwise,
dreaded freezer burn will take place and will rob seafood of its taste and its attractive color. The purpose of the ice, however, is not only to keep the fish at a particular temperature. As the ice slowly melts, this automatically washes the fish – and the natural mucous layer and the moisture of the skin will remain. Whether for fresh water or sea water – we at GEA know what it’s all about. Our 40 models of Geneglace ice machines offer the perfect solution for virtually any application. Daily ice capacity of these machines is between 200 kg and 50 metric tons, depending on the equipment type. Ice machines that directly produce the ice on board are equipped with ice generators especially designed for the rough conditions that prevail on the high seas. They chug along even despite heavy waves and are not sensitive to corrosion by the saline content of sea air. These ice generators are available alone or as compact ice machines with ice packs. Likewise available are accessories such as the following: ice towers for storage, conveyor belts, insulated transport boxes, and dosing systems.
