Deepchill™ Variable-State Ice Slurry in a Fresh Fish Packing Application in Japan
One of the leading suppliers of fresh saury in Japan installed a Deepchill™ Variable-State Ice System and implemented The Deepchill™ Process in 1999, which it used to introduce a new line of branded deepchill™ fresh saury to its customers.
Upon arrival, fish are quickly cooled down to 0 ° C in 50 ton pre-chilling tanks, full of very liquid deepchill™ ice. After it has been sorted and separated by size, a thicker deepchill™ slurry ice is used to maintain the chilled fish in one-ton containers until it can be packed.
Fish are finally placed in Styrofoam boxes which move along a processing line to the Deepchill™ Filling Station, where they are filled with thick deepchill™ ice paste with 60% ice fraction, at a filling rate of 2 seconds per box. The filling station is programmed to handle different sizes of boxes and the flow of deepchill™ is precisely measured accordingly. Once full, the box is sealed and is ready for shipping.
Unprocessed fish is simply stored overnight in deepchill™ slurry ice filled containers for the next day’s production, with no fear of spoilage, thus allowing for a smooth operation of the facility and eliminating the need for overtime hours.
In this highly competitive market, the deepchill™ branded fish supplied by Sunwell’s client sold first and at a substantial premium.
