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 gaine 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.
