Case study, Orkney Salmon Company
Early in 2001, as part of our expansion plans, it was decided to purchase a Baader 142 gutting machine. Because it was not just a case of getting the gutting machine and ‘plugging it in’, we had to make some alterations within our factory. Several Companies were contacted regarding the work required, but really only one company made the commitment and showed any real interest. This was Norfab. The project involved a 3 stage approach.
The first was to fabricate and install conveyors to feed the gutting machine and to take the boxed fish away. Two automatic conveyors were installed, one feeding the gutting machine and one feeding the manual line. A simple 60kg scale controls the conveyor feeding the gutting machine so that there is always salmon in the hopper to go through the machine. Alterations were also made to the bin tipper and fish hopper so that they worked with the new equipment. A complete set of gravity roller conveyors were also installed as part of this project. The original ones were in poor condition and additional new ones were also required in the new layout.
The second stage was to fabricate and install offal removal and blood water/ice removal systems. The offal removal involved installing a centralised tank and pump. All the fish offal was to be collected in this small tank and pumped out of the building into our ensiling tank. This involved re-routing pipe work from the gutting machine cyclones to the offal tank. Also part of this stage of the project was the automatic removal of the blood water and ice. Normal practice meant that when bins of salmon were tipped, all the blood water and ice ended up on the floor, eventually running to the drain. With the ice on the floor, safety was an important element. Norfab built a tank under the tipper/hopper, which now collects almost all of the blood water and ice. A pump and knife valve was added as part of this so that when the bins were tipped the pump started automatically. This waste is then pumped approximately 30 meters to the ice dump.
The third stage was to fabricate and install a vacuum system for kidney removal on the manual gutting line. This involved the installation of 3 liquid ring vacuum pumps and pipe work, a cyclone and 8 vacuum spoons. Again the solid waste from this was pumped directly to the offal tank. The vacuum pumps are set up in such a way that they run in sequence, so if only one is required, only one will run.
The alterations carried out by Norfab have meant that we no longer have to deal with offal, have no health and safety fears with ice on the floor and have improved the general cleanliness of the primary processing area.
Because we were still processing during these projects, Norfab had to work around us. This they did with no hesitation, working weekends and through the night to get the jobs done, always allowing plenty of time to get cleaning and disinfection done ready to start processing.
As with any new installation there will inevitably be teething problems, and there were a few with these projects. What we found with Norfab was that once tasked with any given problem, they were always quick to respond. Norfab were also quick to lend help and advice, working closely with Bryan Rendall (Electrical), our local electrical specialist.
