Use of electricity for drying fishmeal / Electric drying of fish meal

The fishmeal industry is an important industry and has been technologically advanced in recent years. High energy is used in the production of products. In order to gain a better grasp of energy efficiency in the process, an energy and mass flow model is set up for the processing of different raw materials and at the same time a better overview of the processing cycle is obtained. The model also helps to make it easier to influence the quality of fishmeal products, through process control. The main goal of the project is to control energy consumption in the production process and especially during drying and to develop electric drying equipment for air dryers. The drying is the last stage of processing in the circuit and the waste dryer from drying is then used later in the circuit. The aim of the project is to use electricity to heat air for drying fishmeal in an efficient way. In this way, it would be possible to achieve the goal of the fisheries sector to utilize only domestic energy in the production of fishmeal, significantly reduce the import of oil for land processing and significantly reduce the formation of footprints. Measurements in the production process were performed for four types of raw materials, to estimate material flows through the factory. Pressure drop over oil heating equipment was measured and is much higher compared to electric heating equipment. The electric heating equipment has proven successful in HB Grandi Vopnafjörður's fishmeal factory, in terms of energy source, energy efficiency, control and maintenance.

The fish meal industry is an important sector and has applied technology in recent years. Fish meal processing is an energy intensive process. For better control of energy utilization in the process energy‐ and mass flow model was set up for processing different raw material, and simultaneously a better overview for the process. The model is a good tool to have influence on the quality of the fish meal products. The main aim of the project was to control energy usage specially for the drying and to develop electric air heating equipment. The drying is the last step in the process and waste heat is utilized on previous stages in the process. The aim of the project is to utilize electricity to heat air for drying fish meal in a cost effective way. By contrast it would be possible to reach the goal for the Icelandic marine sector to utilize exclusively domestic renewable energy for fish meal processing, reduce imports of oil for shore processing and reduce carbon footprint. Measurements in the process were carried out for four kinds of raw material, for evaluation of mass flow through the process. Pressure drop over the oil air heating equipment was measured higher than for an electric air heater. It has turned out that the electric air heater has proved its worth in HB Grandi fish meal factory in Vopnafjordur, in terms of energy source, energy utilization, controlling and maintenance.

Offshore Aquaculture: Development, building and testing of a deep water mooring system

Emphasis on healthy and safe foods has boosted seafood consumption. At the same time, increased demands for the sustainable use of seafood have encouraged farming and cultivation instead of fishing for wild species. Limited space in coastal areas, however, is hampering global aquaculture production. It is therefore expected that aquaculture and the cultivation of seafood will increasingly move out of the shelter of bays and fjords and more into open sea areas. This change will increase the demands on equipment for offshore fishing, as work will need to be done at greater depths and to deal with conflicts caused by offshore waves and ocean currents. Concrete blocks and traction anchors are traditional equipment for aquaculture production of seafood, but aquaculture manufacturers are now looking for safer and cheaper methods of attaching their equipment to the seabed. Concrete blocks and tug anchors are unsuitable as anchors as they are expensive and need to be very heavy to be used on the high seas, as well as they require a lot of space as they do not withstand vertical conflicts from the environment and / or service boats. Large ships with powerful equipment must be used to bring them far from shore, and this is a very costly operation. Tæknistál ehf. has developed an underwater drill based on new technology that attaches a light screw anchor to the seabed, all the way down to a depth of 70 meters, without the assistance of divers. The project was carried out in collaboration with Matís ohf., Siglfirðing ehf., Ocean Rainforest spf., Offshore Shellfish Inc., SINTEF MRB (R&D) and partly financed with a grant from Tækniþróunarsjóður and NORA. The drill is light, weighing about 900 kg, and is based on a three-point frame with three screw drills at each corner that attaches it to the seabed. Then a screw anchor, up to four meters long, is drilled into the seabed with a fixed service line. Due to the light weight of the bearing, it is possible to use traditional service boats for fire / cultivation, to anchor. Compared to traditional anchors, such as concrete blocks and tow anchors, such drill anchors are considered more environmentally friendly, cheaper and can withstand much more vertical effort and therefore require much less space for fire / cultivation. Such properties are important for aquaculture / cultivation in the sea, but no less for other uses such as floating docks or ammunition. The drilling rig that was developed in the project has passed various effort tests, but it was also tested in mussel farming under real conditions for the open sea for 6 months in Eyjafjörður. Tests took place during the winter in the worst conditions and showed that the anchors held perfectly and withstood the load much better than traditional anchors (concrete blocks) did at the same time. Marketing of products and technical solutions developed in the project is well under way.

With ever increasing seafood consumption and greater environmental concerns for healthier and safer products, the demands on aquaculture production are rising. Limited space for suitable aquaculture sites along coastal zones is now recognized worldwide as a serious limitation for this important industry. The farming or cultivation of seafood is therefore expected to shift increasingly from sheltered fjords and bays to more exposed offshore culture sites. This expansion offshore, away from the visibility of coastal communities, means installing and anchoring aquaculture infrastructures at greater water depths in rough sea. Thus, in order to eliminate the logistical difficulties imposed by transporting and positioning heavy deadweight concrete anchors or drag ‐ anchors offshore, aquaculture operators are seeking more cost ‐ effective and practical mooring solutions like deep water drills using light ‐ weight anchoring systems. Compared to traditional fish farming in sheltered fjords and bays, offshore aquaculture gear requires a much greater holding power as it is highly exposed to considerable physical forces eg by waves and currents. One of the remaining challenges for this offshore expansion is the costly installation of heavy concrete or drag ‐ anchors to hold the aquaculture infrastructures at considerable water depths. Producers are therefore looking for more cost ‐ effective and reliable mooring systems that can be quickly and easily installed, to meet the increased biomass potential. Taeknistal Inc. has developed a new technology to fasten light ‐ weight helical screw anchors into the seabed, at water depths up to 70 meters below surface, without the assistance of divers. The project was carried out in collaboration with Matis Inc., Siglfirdingur Inc., Ocean Rainforest spf., Offshore Shellfish Inc., SINTEF MRB (R&D) and partly financed by grants received from the Technology Development Fund in Iceland and NORA. An innovative drill machine was specially developed for installing helical screw anchors into the seabed. The submersible structure consists of a triangular drill frame with three small drills, using helical screws that are fixed to each corner of the triangle at the bottom of the drill unit. This drilling machine has the advantage of being light ‐ weight, approximately 900 kg, and can be managed by an ordinary aquaculture service vessel. Compared to the traditional anchor types, such as concrete blocks or drag ‐ anchor, the helical screw anchors are more environmentally friendly, less expensive and more resistant to vertical tension. These are all important factors in aquaculture, especially offshore where one can expect high waves and strong currents, in addition to the tension imposed by the larger service vessels when they are attached to the aquaculture lines. Managing the innovative drill machine was tested at open sea and the holding power of the anchors was tested in actual conditions during six winter months, where the screw anchors were drilled into the seabed at an offshore aquaculture site at Eyjafjordur (North Iceland). The results from this test demonstrated that the screw anchors have a holding capacity superior to that of traditional anchors which minimizes the loss of crop, and reduces the environmental impact. Marketing of the products and the technical solutions developed in the project is well under way.

Raw material process in shrimp factories

Shrimp processing has been very successful in improving the utilization of raw materials, and the utilization has decreased from 20% to over 40% in just over twenty years. The use of poly ‐ phosphate (PP) has been important in this process, but these substances have been used together with salt and citric acid as excipients in the pre-processing of the shrimp. Utilization has been the best in the processing of thawed raw materials, but utilization has been significantly poorer in fresh shrimp. In Kampa shrimp processing, fresh shrimp are divided into two main categories; deep-sea shrimp and deep-sea shrimp caught in Ísafjarðardjúpur or Arnarfjörður. Ocean prawns have given better utilization than deep-sea prawns, which in most cases are smaller. The main purpose of this project was to compare the activity of these substances on thawed and fresh shrimp to improve utilization for the latter category. A study was set up to measure weight gain with differently strong blends and different times on fresh shrimp. Three experiments were performed, the first with both deep-sea shrimp and deep-sea shrimp, and the second two with only deep-sea shrimp. Studies were conducted from October 2011 to June 2012. The results of these studies strongly indicated that the pickling time of fresh shrimp needed to be shortened compared to thawed, but a traditional mixture gave the best results. This project was to test snail equipment from 3X Technology, Rotex, and compare the result with the traditional Kampa method, with 660 l. kerum. A new and cheaper method was introduced before this part of the study was carried out and it was therefore decided to cancel that part of the project. Instead, it was decided to focus on chemical research into the uptake of PP substances and what effect this would have on utilization in shrimp processing. Extensive research was started, but its scope is more than enough for a small project like this. Further research is therefore needed to complete this project, but the results obtained from this project are a good basis for further research. The result of the project is improved utilization for pelleting of deep-sea shrimp and deep-sea shrimp, which yields approx. one percentage point during processing.

The shrimp industry has achieved great success in improving the utilization of raw materials with the yield going from about 20% to over 40% in just over twenty years. Use of polyphosphates (a „poly ‐ phosphate„ (PP)) has been important in this process, but these materials have been used along with salt and citric acid as an excipient in the preliminary raw material method for shrimp. Best result has been in processing defrosted (frozen raw material) material with lesser yield using fresh material (unfrozen raw material). Kampi shrimp factory are mainly using two types of fresh raw material, in ‐ fjord shrimp from Arnarfjordur and Isafjardardjup, and deep water shrimp from fresh ‐ fish trawler fishing north of Iceland. The in ‐ fjord shrimp is generally smaller than the deep ‐ water shrimp. The main purpose of this project was to find a way to gain yield in processing the fresh material, and to transfer success in processing the defrosted shrimp to the fresh material. To do so a different strength of ingredients in pre ‐ maturing fluid in raw material method was used along with different time of maturing. The effect of this experience was recorded. Three experiments were conducted, the first with both in ‐ fjord shrimp and deep water shrimp, but the latter two with deep water shrimp only. Studies were conducted from October 2011 to June 2012. Results of these studies strongly indicated that a shorter time should be used for fresh material to gain better yield, but traditional combination of ingredients for maturing blend gave the best result. The second objective of this project was to test Rodex equipment from 3X Technology for raw material processing and compare the results with the traditional method Kampi uses, with 660 l. tubs. Before the test was conducted a new and cheaper method was introduced to this market, making the Rotex equipment unrivaled in this business. The project management team then decided to cancel this part of the project and to focus instead on chemical absorption studies for PP materials and the impact it would have on the utilization of the shrimp. Extensive studies were begun, but their scope is more than can be accomplished in a small project like this one. An advanced project will be needed to complete this study but the attainment of this study is an important input for further research in this area. The yield in fresh shrimp processed in Kampi have improved for about two percentage points as a result of this project, by using different maturing method for the raw material.

Growth in the broadest sense

As the new year draws to a close, it is not out of the question to look at the year that is now coming to an end. Sveinn Margeirsson reviews the year 2012 in Matís' operations, but growth characterized the company's operations during the year.

The growth is reflected in many areas, both as the largest year in the company's history in terms of turnover and not least in Matís' wider project participation both abroad and no less domestically. The number of employees has also increased and the knowledge base has grown. All of this is happening in times of economic hardship and says a lot about the strength of the company and its employees.

Matís is in many ways in line with the progress of food processing in Iceland and the importance of the value chain has become increasingly clear. The value creation is in this way in many links of the chain; it will be in development, production and no less marketing. Matís' strength lies precisely in its involvement in knowledge of the various parts of the value chain, we support food production in its development while at the same time fulfilling our role in terms of food safety and control. Consumers need to have confidence and trust in the products.

Matís' foreign income now amounts to close to 25% of annual turnover and has never been higher. This reflects our success in foreign projects, Matís' position and strength in an international research environment. We have also increased our participation in national projects and Matís' dense network nationwide. In 2012, the company opened two new offices, in the south of the Westfjords and in Snæfellsnes. They are guided by value creation in these areas with special emphasis on Breiðafjörður, where there are great resources in food and biotechnology. In Breiðafjörður, there is a large amount of algae that our biotechnology research has shown can be processed into valuable products, but in parallel with the innovation, Matís can help to combine these new emphases with the existing food production in the area. The key is to work according to the guideline that ensures the greatest value creation.

Food production in Iceland takes place to a large extent outside the capital area and we have good experience of operating establishments around the country to follow the emphases and opportunities in each area, in collaboration with locals. Despite the fact that the development of the establishments entails significant costs, we nevertheless consider this network to be of great value. We have placed great emphasis on increased connections with educational institutions, and it can be said that Matís has made good progress in the bridge-building that needs to take place between educational institutions, research companies and the business community. Experience shows how much that bridge can contribute to increased value creation.

Consumers need to be able to rely on the safety of food production. They also need to be able to trust that the limited funds allocated to research and development activities will be used for development and growth for Icelandic society. I believe that Matís' employees have succeeded well - as the company's growth in 2012 confirms.

Christmas market with food in Höfn

A very popular Christmas market with food and crafts has been held at Höfn in Hornafjörður in December in recent months.

The parties involved in the market are Matís, the Hornafjörður Cultural Center and the State of Vatnajökull. The market offers a lot of food produced in the district, such as dried mutton from the wilderness, hot-smoked mackerel, smoked pork products from Miðskersbúið, vegetable products from Hólabrekka, hot-smoked eel, seafood from Skinney Þinganes, ice from Árbær, birch salt. The market will be open on Saturdays 15 and 22 December from 13:00 -16: 00.

The Christmas market is an outdoor market and is held in stalls that were built this summer. Great care was taken in the construction of the stalls as it was planned that they would look like shark shells, which means that the market has a very Icelandic and old-fashioned look. Various events are offered on the market, such as choir singing, etc. to create a real Hornfirski Christmas mood. There has been a good turnout in the market and food producers who sell food on the market are doing well, as people have been coming to the market from the east to pick up delicious food produced in the region for the festive meal.

Seaweed is an underutilized resource in Iceland

"Icelandic seaweed is an underutilized resource at least here in Iceland, but there are various things going on that are related to algae and they are relevant in our research," says Jón Trausti Kárason, an expert who is one of those related to algae research at Matís.

Jón Trausti says that about eight researchers at Matís work primarily on algae research, although more are related to those projects in one way or another. Among the recent products based on algae research by Matís scientists are skin products that the start-up company Marinox has launched, but they contain bioactive antioxidants that are made from seaweed and are considered particularly good for the skin.

Among other products that are expected to be on the market soon, Jón Trausti mentions algae skyr and barley paste that is added with algae. "In fact, it was a group of students who were with us last summer that started the development of the algae cloud and the product competed on behalf of Iceland in Ecotrophelia, which is a student competition with ecological innovation in food production. This went so well that the development work was continued and now the algae cloud is coming. Here is food on the go that is skyr and kelp flour in the base but flavored with blueberries and honey, "says Jón Trausti.

Jón Trausti, along with others at Matís, is a representative of the young generation. He came to Matís before he finished his studies, then in projects related to his studies. As a result, opportunities were created where the gap between industry and the scientific community was bridged, and Jón Trausti, together with other Matís employees, is an important link in that value chain. For the young generation, it is an exciting task to be in the middle of a whirlwind of food production in Iceland, but with a large interface with the education system. The ideal of this young generation is lofty and exciting. It is, among other things, strengthening Iceland's position as a food-producing nation, but changes in the environment have created conditions that mean that we Icelanders see opportunities for great progress in the production of raw materials, which may not have been considered for decades.

Raw material utilization is by far the best in Iceland

This was stated in a speech by Haukur Már Gestsson, an economist who works within the Sjávarklasan, at the Fisheries Conference in Reykjavík recently, and also recently Sigjón Arason, Matís' chief engineer, made a good report on Stöðvar 2's news.

The utilization of cod in the North Atlantic countries is noticeably best in Iceland or 76%, while it is 50% in the Faroe Islands, 45% in Canada and 43% in Greenland. "I believe that the main reason for better utilization here is greater utilization of by-products, and this is undoubtedly thanks to both the regulations and the good collaboration between companies and Matís, but good fillet utilization certainly plays a part. The liver is a good example of a product that is well used in this country. Most of it goes into fish oil and is boiled down. Eggs are also new.

Utilization to increase
The same is true of heads and bones. Almost all cod heads that come to Iceland go for drying, as does a growing part of the cod heads that fall on freezer trawlers. These products are sold to Nigeria. From the accompanying graph, it can be assumed that utilization has deteriorated in Iceland since 2009. Haukur says that this does not have to be the case. "Care must be taken in comparing utilization between individual years. For example, a product manufactured in 2009 is sometimes not shown in export figures for the following year. It therefore makes more sense to look at the graph over a longer period of time and accordingly the utilization is increasing. On the other hand, it can be seen from the diagram that utilization in the other countries has been declining. I have no explanation for that. "

Norwegians strong

According to Haukur, he did not have good enough data to include Norway in this comparison. "Norwegians have looked at this themselves and according to that their utilization is about 41%, but since a different method was used than I used, care must be taken in comparing these figures. Norway is more powerful than most other nations in exploring opportunities in by-products, for example by exporting eggs and oysters to Asia. A special organization was established there, RUBIN, which received a lot of funding to research by-products, but this institution has actually just been closed down today. "

Guts and heads are of little use
"I believe that Icelanders should be able to go one step further to make better use of, for example, gutters, heads and bones and maximize their value. The head is between 20 and 30% of each fish and according to a Matís survey, only a small part of the heads is used if the cod is excluded, "says Haukur Már Gestsson in the end.

Improved water usage in fish processing

The aim of this preliminary project was to obtain basic information on water use in fish processing as well as organic substances lost in the effluent. With improved water use, it is possible to achieve operational efficiency and increase the value of production by utilizing by-products from the effluent from processing water. Water consumption in Iceland is much higher than in neighboring countries. Regulations are also being tightened with increasing restrictions on waste disposal and waste of water. The status of knowledge was examined with respect to the aforementioned factors to analyze the benefits of clean production technology in fish processing.

The project objective was to summarize state of the art knowledge concerning water usage and utilization of by-products from effluents in fish processing. Operation can be improved with better use of resources entailing increased value for raw material processed. Water usage in fish processing in Iceland is more than in neighboring countries, while environmental regulations are becoming stricter. Methods for cleaner fish processing were researched in terms of recommending improvements for fish processing factories.

The Product Development Center for Marine Products aims to increase value creation

The location of Matís' offices across the country has made it easier for entrepreneurs to seek cooperation and support.

Páll Gunnar Pálsson, a food scientist at Matís, says that one of the company's most common tasks is participation in product development and organization of work processes at food companies. "Matís' main guiding principle is to increase the quality, value, health and safety of production and thus strengthen the competitiveness of the Icelandic economy on an international level and promote better public health."

Ten establishments

"Matís' headquarters are in Reykjavík, and in addition there are nine offices throughout the country. The activities are diverse, but with a special emphasis on collaboration with companies and individuals. Matís has a staff of about one hundred and within that group are many of the country's leading experts in food and biotechnology as well as a number of master's and doctoral students in research-related studies. "

Páll Gunnar says that many of the projects are small and limited and therefore do not have the possibility of grants from the competition funds, in addition to which the application deadline and processing time for funds can be so long that the projects burn out while waiting ..

Necessary to act quickly

"The acquisition of seafood depends on the seasons and if it is not possible to start a project at a certain time, the waiting time can be long. It is therefore important to be able to react quickly and start working immediately on important project ideas that arise.

In recent years, Mátís has placed great emphasis on collaboration with individuals and companies who are looking for ways to increase value or are preparing to process new products.

For this reason, we launched the project Product Development Center for Marine Products with the support of the Fisheries Project Fund. Within this, work is being done on various product development projects in the field of fisheries throughout the country. The project is intended to meet the need of the Icelandic fishing industry for product development and further processing. In light of the experience gained from the operation, the importance of being able to respond to companies 'and individuals' requests for assistance with product development has increased, "says Páll Gunnar.

We welcome everyone

Páll Gunnar says that projects that find their way into Matís 'board have more often than not come from companies and individuals in the countryside, and the strengthening of Matís' operations in the countryside has had a great impact on this.

"We welcome everyone who has a good idea for product development or needs help to get their idea in the right shape, and we can get started much earlier than if we had to try to finance through the traditional fund system.

In the two years that the project has been in operation, Matís has been involved in more than 50 projects and some of them have already returned products and new activities. These include products based on kelp, such as kelp and ointments. We are currently working on the development of dietary supplements from kelp, barley pasta, smoking saithe, oil made from lobster, health snacks from seafood, improved utilization of grayling, guidelines for people who want to make their own salted fish, to name a few, "says Páll Gunnar.
