Slurry Ice Systems is unique. No other company can boast the depth of combined experience held in ice generator development and hands-on fishing. Slurry Ice Systems supplies an exclusive range of binary ice generators currently used to good effect in both Pelagic and White-fish industries. The ice's semi liquid state allows it to flow, working fast and efficiently by void invasion of the item to be preserved thereby chilling from inside and out.

Slurry Ice News:

The S 0.5 draws a lot of interest at both world fishing in Vigo and Dan fish in Aalborg ,the little machine performed very well at both shows producing between 40 and 55 litres / hr . Giving potential customer a true feel as to the potential of Slurry Ice.

Managing Director James Duthie (right) when asked, if anything is worn under the kilt, he assured passers by "it's all in perfect working order".

Tobis HG306
As reported previously, Slurry Ice Systems  secured the order to supply the new Danish white fish trawler Tobis with a S16 system
The system provides 72kw of cooling to the vessels fish handling operation, Tobis was launched in May 2009 - designed to deliver top quality fresh fish to the market by rapid chilling using Slurry Ice. MORE >>>

A ten generator boost for onboard RSW system MORE >>>

The Peterhead based company Lunar Fishing has just taken delivery of their two new whitefish trawlers Ocean Harvest and Harvester from Karstensen Skipverft in Denmark. They are the first Scottish fishing vessels to be fitted with a S8 Slurry Ice System supplied buy Slurry Ice Systems, Scotland which is also based in Peterhead.
The company which was started 3 years ago by ex pelagic skipper James Duthie has been growing in strength by supplying vessels and fish factories throughout Europe, the largest system being a 20 generator system installed onboard the Willem van der Zwan, one of the largest freezer trawlers in the
world, in co-operation with GEA Grenco from Holland. This system is capable of producing in excess of 400t of Slurry Ice at 20% ice.
Slurry Ice has now broken into the Scottish whitefish market by winning the order to supply a system onboard each of the new Lunar vessels, Harvester and Ocean Harvest and has recently secured an order for a similar system to be installed onboard the Endeavour from Banff being built by Macduff Shipyard. Two generators and a holding tank were also supplied to Forbes Refrigeration as part of a system built and installed by Forbes Refrigeration for another Peterhead vessel Starlight Rays Slurry Ice Systems previously supplied a 10 generator system for the pelagic vessel Unity from Fraserburgh installed by Skogland AS in Norway.

A joint venture has been set up between Slurry Ice Systems Ltd., Scotland and Mode-Slurry Ice Systems in Iceland, pooling their resources to provide one of the best rapid cooling products in today’s market.

Slurry ice generators supplied by both companies are the only generators with a CE-PED Certification. The Generators have gone through rigorous testing by our partners before being supplied to customers, ensuring that both partner and customer is satisfied with the units they are working with.

Slurry Ice Systems Ltd. and its partner companies are world leaders in the field of developing and manufacturing slurry ice systems.

Slurry Ice is also known as "slush ice" "liquid ice" and "binary ice".

Case study
Seafood Scotland, Seafish, the vessel Challenge II UL33 and Liquid Ice (Icelandic firm) have been working together to assess the impact liquid ice has on the quality of fish landed. A liquid-ice plant was supplied by the manufacturers on a trial basis and this was installed on the Challenge II UL33. The main objective of the project was to ascertain whether the quality of fish landed in bins/boxes improved when the fish was stored in liquid ice as opposed to flake ice... more >>>
Trial 1
Monitoring of fish temperatures in bins containing both liquid-ice and flake ice.
Fish handling: The haul of fish was emptied into the reception hopper. The crew started handling the fish after the next haul had begun. Two crew members were located on the upper deck, while two crew members were permanently in the fishroom The fish were transported from the reception hopper by a conveyor system. The fish were then gutted, either by hand or machine... more >>>
Trial 2
Monitoring of fish temperatures, stored in liquid ice, with bins filled to various capacity.
A small trial was set up to see how quickly the fish stored in liquid-ice dropped in temperature, as the bin was being filled to capacity. Normal practice in the fishroom included a thick layer of flake ice at the bottom of each bin... more >>>
Trial 3
Monitoring of fish temperatures in a bin containing flake ice.
To produce more evidence of the slower cooling rate of fish stored in flake ice it was decided to monitor another bin of fish containing flake ice. Temperature checks were taken from fish stored in flake ice at regular intervals, every 15 minutes, for the first hour, then every 30 minutes for the remainder of the trial... more >>>
Trial 4
Monitoring of fish temperatures in boxes containing both liquid-ice and flake ice. Temperature checks were taken from fish stored in both liquid-ice and flake ice at regular intervals. Both boxes sampled were from the same fishing operation.
A thermocouple was placed into the fillet of a fish and the fish was placed in the middle of a box. The same procedure was used for each box. Normal practice in the fishroom included a thick layer of flake ice at the bottom of each box... more >>>
Trial 5
Pre-cooling of fish in the fish hopper.
The main decision to install the liquid ice machine onboard the Challenge II UL33 was to enable the fish to be chilled immediately after they are taken onboard. This is important in the summer months when the temperature of the sea can rise to approximately 18°C. It was decided to run a preliminary trial for assistance in future project work... more>>>
Trial 6
Cooling and monitoring of fish temperatures through the handling system
The fish handling system onboard provides small bins for the crew to store fish prior to washing. It was decided to monitor the fish temperatures in these “grading” bins to establish the benefits of applying liquid-ice, to the fish lying in these grading bins over a considerable period. All fish taken onboard the vessel are washed thoroughly through the fish handling system. The fishwasher uses seawater... more >>>
Follow-up project
Follow through project work
After the catch was discharged in Ullapool the fish were transported to the north-east in refrigerated vehicles. As is normal practice when landing the majority of fish landed in boxes are auctioned on Peterhead Fishmarket while the fish landed in bins are contract sold to a small number of buyers... more
