WORLD RECORD IN FILLETING OF SMALL FISH

WORLD RECORD IN FILLETING OF SMALL FISH

During the recent demo test for customers from Russia, Romania, Latvia and Finland, SEAC completed an extrordinary test – to fillet and ”belly clean” small sprats, Baltic herring and anchovy down to 6-8 grams. During the same test they processed up to six different end products from the same fish in the SEAC FPM-400 Nobbing and Filleting machine.
The Swedish company SEAC AB and it’s founder Ulf Groenqvist started to redevelop former Swedish fish processing machine manufacturer ARENCO’s herring machines also for smaller fish, and during 2010-2012 they introduced their brand new machine progamme – SEAC FPM machine – today the one and only filleting machine for very, very small fish in the world.

Mr Groenqvist noticed that the fish became smaller and smaller both in Baltic Sea but also in the Mediterrenean Sea from the 1990s to this day. Similar results were found all over the world.

During the 5–8 years the SEAC FPM-400 machine has been on the market, exciting new developments have been made – both on new fish species but also on new end products.

The tests started with smaller Baltic herring and vendace (40–70 fpk) and the next step was sprats and anchovy (two very popular fish species), but due to their smallness – very difficult to process by hand (try to hold a 10 gram fish and then try to fillet it by hand, and you will understand why).WORLD RECORD IN FILLETING OF SMALL FISH

Normally no fish processing machine in the world can compare with hand filleting, but now, when we are close to the edge of smallness of fish, the machine works even better than hand filleting. Furthermore, with a processing machine you avoid injuries during filleting; the machine works constantly while the filleter gets tired after a while, and you improve the hygienic standard inside the factory.

But perhaps most important is the capacity. The machine can do up to 400 fish pockets/min (F 30 – smallest pocket size) but 4-5 people can only fill up to 325/330 fish/min into the pockets. The SEAC FPM-200 (Nobbing and Filleting machine) reduces the number of operators by 10-12, but the FPM-400 filleting machine reduces the number of operators by up to 40 people.

Today there is no autofeeder that can feed fish so small (today’s existing feeders from PERUZA or SWEDEFISH can do down to approx 50/60 fpk) but on smaller sizes the accurracy or the capacity is yet not enough. Today, such autofeeders don’t increase the capacity but only reduces the number of operators.

BIG DEMO TEST:

During the BIG DEMO TEST in Sweden, companies from four different countries tested their defrosted Swedish Baltic herring and sprats but also sprats from Black Sea and from both Latvia and Russia part of the Baltic Sea. Also some defrosted anchovy from Turkey where tested.

All fish where defrosted in cold water and, of course, the inside temperature was zero degrees or more. Some of the fish was very soft; some belly cracked – but due to SEAC unique mechanical gutting system with individual head measuring system – included in the SEAC FPM-series – it looks like ”the softer or worse quality of the fish – the better production”.

Most other fish processing machines use vacuum gutting when removing the entrails from the stomach and if fish is defrosted, poor quality or belly cracked, the vaccum has problems, but the mechanical gutting system on SEAC FPM-series works almost exactly as hand-gutting with all advantages this gives.

End products from test:

A H&G (beheaded and gutted) with tail left on fish cutlet
B H&G + T (beheaded, gutted and tailcut)
Both A and B are done in SEAC FPM-200 H&G+T machine and yield should be from 65 up to 72%.
C+D H&G (with or without tail and ”belly cleaned). This is a ”new end-product” coming uon the market worldwide. Here you open the belly with two horizontal knives (cutting away the part of the fish where there are normally worms and parasites) and also the black membrane inside the belly cavity is removed and the blood strain under the back bone is removed.

E+F Butterfly fillet with or without tail. Here the back- and belly-bones are removed by two angled set of knives and the outcome is a nice butterfly fillet ready to be cooked/eaten.

Both C to F are done in SEAC FPM-400 (which is SEAC FPM-200 + a filleting machine – SEAC FPM-350)
Result from the test = NEW WORLD RECORD

Test No 1: Filleting of Baltic sprats (64 fish = 576 grams, about 9 grams each). End result: 241,5 gram fillets – yield 43%. Different fish fat consistence due to summer and winter fishing.
