FILLETING LINE WITH INTEGRATED ROE EXTRACTION

It was since the launching of the Baader 212 on the market that it became evident that there was a need for a processing technique covering a larger size range both for pollock and cod.

That is why Baader has now developed an automatic filleting line for heading, gutting and filleting as well as for the evisceration and of roe extraction from Pollock and cod, namely Baader 192. This machine which operates within the range from about 40 to 70 cm, can be used for filleting salmon like fish as well. The through put rate of the machine is about 90 fish per minute. The machine is also designed for processing saithe and other types of whitefish. At a later date it will also be possible to purchase only the heading section of the machine in order to obtain a clean product with roe that is almost free of damage.

First trials on board a factory ship have shown that the machine is extremely stable during production and that the yield is considerably higher than that of its predecessors.

As far as the ratio between yield and capacity is concerned, the opinion of the experts is that the machine is an alternative for the use at sea and ashore since the expenditure on personnel, the capacity, the quality of the cuts and the yield are approaching a level which is hardly inferior to that of the previous machines used ashore. The working processes from heading up to filleting are realized in one machine following a single loading process, i.e. the unpleasant matter of heading and gutting within this machine is already coped with in a manner matching the connected filleting section. Thus, personnel is saved as well. The maximum operator requirements are two persons.

Both the size controlled head cutting system and the innovative system transferring the fish from transverse into longitudinal direction are installed. A new synchronization unit ensures that the fish is fed in an exactly timed manner on the correct horizon through the machine. On its way through the machine, the fish is processed individually and as a function of its size by the different tools.

MERLUZA FILLETING MACHINES ON DISPLAY

Due to its special bone structure the merluza places other demands on the processing technique than whitefish, such as cod or saithe do. Consequently, it is important that, the surface of the fillet and the completely different bone structure – in particular the spine – are taken into account by providing special tools.

The Baader 210, for example, is a machine which, when equipped with a special scraping tool, can pull the fillet away from the back bone in the same way as is done by hand with the thumb. The machine is able to process up to 50 fish/min and requires only one operator. It is made of stainless materials. Spring loaded back severing knives ensure that the cut is performed as close as possible to the skeleton which makes for a considerably higher yield in comparison with that of its predecessor, the Baade 188.

The Baader 210 processes fish within a range from about 24 to 64 cm in total length.

For the larger Cape hakes it is advantageous to use the Baader 211. Although the throughput rate of this machine is only 32 fish/min, it is, however, able to process the same or greater amounts of products than the Baader 210 due to the higher unit weight of the fish. Its working range is between 32 to 100 cm in total fish length which corresponds to a weight range from about 500 to 5,500gHere, the special design of the scraping knife takes the bone structure of the fish into consideration as well. The machine is laid out so that mechanical stresses would not excessively strain the machine even when processing the largest fish possible. The spring loaded knives make the highest possible yield. For both the Baader 210 and 211 the initial product must be both headed and gutted. When combined with the Baader 52DS, both machines can be used for the deep skinning of Cape hake.

As regards the operational reliability and hygiene, these machines are designed to the latest technology.

Exercise 2. Answer the questions:

1. Why does merluza place other demands on processing technique?

2. How does the Baader 210 act?

3. Within what range does it process the fish?

4. What is the throughput of this machine?

5. What makes the highest yield possible?

Exercise 1. Read and translate the articles from the magazine World Fishing:

SKINNING MODIFICATIONS IMPROVE PROCESSING

Swedefish Machinery has modified the “Skinning-wheel” to handle mackerel fillets. The first installation was in a Danish company’s processing line for canned mackerel. The filleting machine that is used is a Baader 35. For skinner, any filleter such as Arenco, Baader, or WMK can be used as long as it produces proper fillets (well centred).

The fillets are completely cleaned from “silver” and have a slight light brown surface. No further trimming is needed and the fillets can be fed direct into the process.

It is possible (under production) to change the thickness of the layer that should be removed. Thus it is possible to change from slight “silver to completely clean (light brown) without stopping the machine.

The Skinning-wheel is the same used for herring except for the new modified units which also can be used for herring but not reversed. The change from mackerel (no “silver”) to herring (“maximum silver”) should take place within about five minutes.

When Swedefish introduced its “Skinning-wheel”, it was primarily meant for skinning block fillets from herring. Significant for the method used in the machine is that it allows a maximum of silver to remain on the surface of the fillets. This is desired especially by those customers who produce marinated herring products in glass jars with clear marinade.

1. What has Sweedefish Machinery modified the “Skinning-wheel” for?

2. What is the appearance of he fillets after sinning?

1. TECHNOLOGY ADVANCES FOR TRIMMING AND PORTIONING

A next generation of intelligent waterjet cutting machines that will meet all its customers trimming and portioning requirements has been introduced by the Danish manufacturer, Lumetech A/S.

The demanding requirements of the marketplace have led Lumetech to develop this new generation of machine that are able to combine high flexibility with high capacity in the most optimal way.

The demand for flexibility has been created by the increasing number of producers who are doing further processing in response to the ongoing pressure for new advances.

Lumetech’s new concept is based on a system of super-flexible hardware modules, capable of carrying out any known cutting pattern.

The cutting unit is an advanced X/Y robot, which is able to carry out even the most demanding cutting patterns. The cuts can be placed in any direction on the conveyor, with resulting patterns limited only by imagination.

Flexible hardware is only as good as the software controlling it, and Lumetech software is built with exactly that in mind. First of all it is modular like the hardware, hence it is able to control any combination of hardware modules. Secondly, the really interesting bits which are used for laying out the cutting patterns, are designed in an ingenious way to enable them to respond quickly to modifications which is very important to the processor.

Tha capacity of the Lumetech system is determined by the number of cutting modules mounted on the machine. Increasing capacity needs can be accommodated even after installation by adding more modules.

Introduced alongside the cutting machine is a new pioneering software application for the purpose of trimming and portioning. Based on known portioning patterns Lumetech has optimized the procedure of selection, giving the Production Manager the opportunity to enter the actual prices of the day for each of the products produced. To ensure optimal yield the Lumetech computer will then calculate the optimal combination of portions for each individual fillet and lay out a cut pattern accordingly.

Only three or four persons are necessary to operate the Lumetech machine processing 25 fillets per minute.

Exercise 2. Answer the questions:

1. What is the manufacturer of this device?

2. What demanding requirement does this machine meet?

3. What is the capacity of the device determined by?

4. How many operators are required to operate this machine?

5. How will the computer ensure the optimal yield?

2. TRIMMING AND PORTIONING MACHINES

Lumetech portioning machines provide you with a number of new advantages. Lumetech is using an advanced x/y cutting unit with a cutting head able to move in all directions and even follow the product when cutting. All Cut patterns can be performed using only one cutting head. This adds flexibility while reducing water and power consumption. The Lumetech machine is constructed in modules. This means you can add features to your machine as production needs increase. Also the software is based on modules allowing an easy update with new cut patterns.

After entering your day’s actual selling prices, the Lumetech computer will evaluate each fillet and optimize the chosen portions on an economic basis, allowing the highest possible return on each individual fillet.
