Animal feed producer ups uniformity, cuts cycle times with fluidised bed mixing

by Steve Knauth, Marketing Manager, Munson Machinery Co Inc, Canada
Country Junction Feeds has produced animal feed products in Alberta, Canada for over 100 years. Today, it offers a full line of organic wet and dry feeds for cattle, hogs, poultry, horses, bison, elk, goats and sheep. To improve batch consistency and prevent damage when adding liquids to fragile ingredients, the company installed a fluidised-bed type mixer on its “wet feed" production line.

Dry feed in raw or pelletised form is typically pre-blended in a 2000kg capacity mixer. The wet blending process adds oils and/or molasses to rolled oats, barley, pellets and “bull ration” calf feed for nutrition and palatability as well as dust control.

To blend dry ingredients with liquid additions in batches of up to 300kg, the company installed a Munson model MF-18-SS fluidised bed mixer.

"Fluidised bed mixing brought more batch-to-batch consistency than the previous auger mixer," explains Mark Shantz, Country Junction’s Maintenance Manager, adding that it imparts less shear than the auger mixer, reducing product degradation, particularly with fragile materials.

How liquid additions are mixed with dry blends
To initiate a mixing cycle, an operator enters a pre-programmed recipe at a plant workstation. Individual ingredients, stored in outdoor granaries, are transported by chain drag conveyors to the aforementioned dry mixer for pre-blending.

Blended batches discharged into bins are then conveyed by either of two drag chain conveyors to the fluidised bed mixer. Load cells supporting the mixer transmit weight gain information to a PLC, which stops the conveyor once the preset batch weight has been gained, with +/- 1kg accuracy.

Once mixing begins, a fluid volume of oil or molasses equivalent to 3-to-10 percent of the dry premix weight is automatically metered from a 20kg capacity vessel and gravity discharged into the top centre intake of the fluidised bed mixer.

Zinc and omega-3 fatty acids

by Neil Auchterlonie, Technical Director, IFFO

Researchers from Nofima, the Norwegian research organisation, reported last month that the barrier tissue of salmon is affected by zinc and omega-3 levels in feed, in a recent piece of scientific work that was funded by the Norwegian Seafood Research Fund (FHF).

Why is this important? Well, the integrity of salmon skin, intestine and gill tissues is vital for the health of the fish. These barriers are recognised as important first lines of defence against pathogens, as well as being important in helping the organism handle physical stressors such as fluctuations in temperature, salinity, or water quality in general.
The article that has been presented on the Nofima website points out the importance of these compounds nutritionally, and particularly in relation to the changes we are seeing in feed formulations such as new feeds specifically for recirculation systems, as well as the obvious dominance of plant-based raw materials in modern feed formulations.

The research set out to investigate whether changes in feed composition would affect the health and robustness of farmed salmon, and the scientists looked specifically at the interaction of zinc and marine source omega-3 fatty acids in feed, for parr to post-smolt in recirculation systems.

It seems to be a part of an ongoing programme of work that has looked at the general robustness of fish in the aquaculture environment, which is highly applied and very relevant work. The results are described in the context of the health and welfare of the fish, and those are obvious impacts related to the ability of the salmon to cope with a pathogen challenge, whether it is ISA virus or sea lice.

This science is important in the context of declining marine ingredient inclusions in aquafeeds. Fishmeal and fish oil are excellent sources of many micronutrients, and among the many different compounds present that contribute to fish (and consumer) health are zinc and the long chain fatty acids, EPA and DHA.

The potential value of blockchain technology in the seafood supply chain

by Bryan Horsu, Master Student at the University of Applied Sciences, the Netherlands, Wesley Malcorps, PhD Student at the Institute of Aquaculture, University of Stirling, UK, Paul van der Heijden, Founder at MatureDevelopment BV, the Netherlands

A growing population with an increasing appetite for highly nutritious seafood resulted in an increase in global fish consumption from 9.96kg in 1961 until 19.86kg in 2013 (FAO, 2018). Capture fisheries and aquaculture are important contributors to fulfill the growing global demand for seafood (Food and Agriculture Organisation, 2018).
However, both industries are made up of complex global supply chains and are subjected to social and environmental challenges. Increasing consumer awareness and food safety requires increasing traceability and transparency along these supply chains.

This article explores briefly how distributed ledger technology, such as blockchain, could increase the traceability and transparency of the seafood industry.

It starts with a brief explanation of the potential of this technology in the aquaculture sector, in particular the aquafeed sector. Secondly, it will zoom in on the capture fishery sector through a conducted survey at a fishing company in the Netherlands.

Aquaculture, aquafeed and complex global supply chains
Capture fisheries have been close to their production limits and, as a result, the aquaculture industry is growing faster than any other food-producing sector. Large amounts of aquafeed are required in order to sustain this growth rate in the coming decades.

Most life cycle assessments (LCAs) suggest that aquafeed accounts for most of the environmental impact of fed aquaculture production (Little et al., 2018). However, this impact is variable depending on the type and source of the feed ingredients.

Therefore, improved traceability and transparency along the supply chain could provide more accurate insight in the environmental performance and could highlight sustainability issues.

APA Chennai 2019: A Blue Revolution for India’s aquaculture

by Roger Gilbert, publisher, International Aquafeed

Chennai was hot and dry in June 2019.  Over 40C in the shade with water shortages featured in global news reports and a city having to supplement its supplies with long-haul tanker deliveries to keep its population hydrated.

Not an encouraging destination to travel to at this time of year. However, this was not sufficient to discourage some 5000-plus delegates, from across India and around the world, making their way to India’s largest southern city to attend the World Aquaculture Society’s first ‘Asia Pacific Aquaculture 2019,’ in India which featured a combined conference and expo and held at Chennai’s Convention Centre.

It was heartening to see how many delegates had registered for the multitude of conferences on offer and/or to attend the exhibition in an air-conditioned, modern facility which offered refreshments of both coffee and water plus a full buffet lunch on each of the three days.

This was a dynamic and bustling show with a host of local and foreign aquaculture companies looking to do business in a much over-looked yet highly motivated industry. Most international companies had their local representatives on hand to engage with visitors, but as all Indian speak English it attracted the management from some larger international companies who went on to host special events, such as Aker BioMarine holding its annual celebratory dinner during the convention.

International Aquafeed was present on the exhibition floor and had visitors who took away over 1300 copies of the latest June 2019 edition of the magazine plus back issues on display. That was in addition to the conference bags which contained copies of the magazine and distributed to over 3000 attendees pre-registered for the conference.

This was an exceptional meeting by any world standard, and one which offered an extensive poster display covering a wide range of research results carried out by a multitude of in-country universities and organisations plus those from overseas. The event also offered a pre-conference tour of a local hatchery and feedmill.

Expert topic: Lobster

by Daniel Jackson, Production Editor, International Aquafeed

The elusive cultured lobster

So pronounced are the paralells between human and lobster, the Canadian clinical psychologist Jordan Peterson dedicates a chapter to the crustacean in his bestselling self-help book, 12 Rules for Life. We can learn a lot about ourselves from the humble lobster, he says, and I’m inclined to think he’s right.

The ability to co-operate effectively in large numbers is what puts us at the top of the food chain, and co-operation is essential if we are to obtain an elusive prize – the cultured lobster.

The challenges the species presents to the aquaculture industry are varied and will require input from all its constituent parts. From innovations in the manufacture of durable netting to research in feed formulation. Efforts to pull these various strands together are currently underway, but there is still much to learn and several obstacles to overcome.

For example, it is not even known at present what juvenile European lobsters eat (though in captivity the answer seems to be ‘pretty much anything that drifts by’).

One thing that’s not in any doubt is the lobster’s value as a commodity. Fishing for them is a hugely profitable enterprise, and one that is becoming more so every year. For a species so synonymous with seafood, relatively few are caught (just 3300 tonnes in the UK in 2016). But the crustacean punches above its weight.

It accounts for just over 0.5 percent of the total British seafood catch, but over five percent of the profits. If catching them is so lucrative, might growing them be even more so?

The overwhelming majority of lobsters are currently caught in the wild. Farming them is technically challenging, and on a large scale not yet commercially viable. But for those who work out how to do it successfully there is a rich seam waiting to be plundered.

Fish farming under the microscope: How innovative technology helps to increase aquaculture productivity

by Andrew Monk, Co-founder and Director, ioLight Magnificent Mobile Microscopes, UK

The world population is growing rapidly. In fact, the United Nations estimates it will reach 11.2 billion by 2100, with approximately 83 million people being added to the world’s population every year. Feeding over 11 billion people is a huge concern, as it will put enormous strain on the earth’s ability to produce enough food. An answer to the future global food challenge may be through the use of sustainable fish farming.

The UN’s Food and Agriculture Organisation reports that the average amount of fish eaten per-capita globally has more than doubled from 9kg in 1961 to 20.2kg in 2015. Of course, there are well-publicised cases of overfishing.

However, much of this growth has been from aquaculture. In 2016, 46.8 percent of the fish we ate came from aquaculture, a rapid growth from just 25.7 percent in 2000. This data includes finfish, crustaceans and molluscs.

Aquaculture is the fastest growing food production sector in the world and is considered a practical and sustainable method to produce food and bridge the gap between supply and demand.

However, aquaculture faces many challenges and one of the biggest is combating disease. For example, infectious disease is currently the single most devastating problem in shrimp culture and presents on-going threats to other aquaculture sectors. In addition, there is increasing concern over the consequences of newly emerging diseases in aquaculture.

As with any form of farming, growing large amounts of food in a small space increases the incidence of infection and disease, which can spread extremely rapidly through a stock of 90,000 fish confined to a pen.

For this reason, fish farms are looking for modern innovative methods to ensure that fish are kept healthy. Better disease control, feed and nutrition help to minimise losses and produce a high-quality product. If fish farming is the answer to a sustainable food source, rapid disease and parasite diagnosis, together with improved health management, will be key to increasing stock levels.

Large farms continuously monitor water, but there is no substitute for visually inspecting the fish, and early detection of small parasites requires a microscope. As part of a good health management plan, routine parasite and disease screening should be completed regularly.

R&D applications for aquafeed extrudates

by Brabender GmbH

Laboratory-scale testing to determine appropriateness for species and sustainability

Providing a proper supply of protein for the world's continuously increasing population is a tremendous global challenge. Consumption of fish and seafood is traditionally anchored in many dietary cultures and recommended as a significant source of protein for nutritional enhancement. However, in view of the present situation with overfished oceans around the globe, it is necessary to find alter-natives: Here aquaculture provides a solution. Consequentially the global annual yield from aquaculture, amounting to approximately 100 million tons since 2015, has outstripped the "wild catch" quantity for human consumption. Further growth is a foregone conclusion: A 50 percent increase in production is predicted for the next two decades.
Whether floating, suspended, or slowly sinking: With the TwinLab-F 20/40 it is possible to test aquafeed produced from various raw materials (such as insect protein, see upper row) on a laboratory scale.

Booming Aquacultures: Which feed for which species?
We spoke with Julian Foerster (JF) and Michael Landers (ML), the application technicians at Bra-bender's extrusion laboratory, about using custom tailored extruded products to solve the problems presently faced by the aquafeed industry. 

Extruded Aquafeed – where does demand exist?
JF: Whether fish farming with flow-through systems, netcages, or resource-preserving recirculating systems such as aquaponic or offshore farms – all these fish and crustaceans need feed; nearly 40 million tons per year worldwide.  70 percent is produced by the leading aquafeed producers in the Asian-Pacific region, particularly in China, 10 percent comes from Latin America, and another 10 percent from Europe. Of course, one has to differentiate among which species should be fed. Presently 30 percent of production is used for carp breeding, 15 percent is required for crustaceans, followed by tilapia, catfish, salmon, and trout farms.

ML: Extruded products offer trend-setting possibilities promising market success and product innovation in developing the proper feed for each species on a practical basis. There is practically no other process that offers so much potential for entirely reshaping an aquafeed matrix. For this rea-son purely mechanical pelleting presses have been increasingly replaced by state-of-the-art extrusion technology for production. Today laboratory extruders are therefore necessary "tools" for product developers in companies as well as at universities and research institutes. With the TwinLab-F 20/40, Brabender has now introduced its current top model for the R&D laboratory world.

Julian Foerster

What is the "proper" feed for a species?
JF: First we need to determine the raw materials and their percentage of protein and carbohydrate that are practical for various product applications. It is first necessary to determine the tendency of the feed to float or sink, depending on the feeding habits of the specific type of fish. In principle, floating feed tends to be eaten by bottom fish such as carp and catfish, which can also be a matter of training.  Salmon and trout prefer feed that sinks slowly, shrimp, by contrast, like food that sinks quickly.

ML: Correspondingly, it is necessary to select different process settings for production. For floating feed, including suspended or slowly sinking feed, we operate with hot extrusion at temperatures over 100°C. This results in good pellet expansion. For sinking feed, i.e. production of quickly sinking pellets with minimum expansion, cold extrusion is the preferable method.

Which challenges need to be solved in the laboratory?
ML: Whether or not a product expands depends, among other things, on the moisture content as well as generally from the recipe, particularly the percentage of protein, carbohydrates, and fat in the initial mixture, which is also varies ichthyologically depending on the species. As a product developer we can determine this precisely in the laboratory. The TwinLab allows us to put various compositions and recipes on the test bench. The degree of expansion can be adjusted and changed with variable process settings. Most important is optimal cohesion of the constituents to prevent the pellets from disintegrating. This allows us to test the product characteristics to ensure the recipes are properly adapted to the type of fish and farming method. For example, some species require a high percent-age of fat in the feed, however too much oil delays expansion - here we can examine possible max-imums using the TwinLab. And naturally, the reverse is true, when it is necessary to determine the minimum quantities of ingredients, e.g. for optimisation of the sinking characteristics. This can be regulated by adding water, among other things, whereby the pellets are then dried.

JF: For forward-looking, sustainable product design – keyword: Sustainability – the trend is departing from use of fish meal or by products from commercial fishing. Instead, it is necessary to study which sources of protein with which characteristics and percentages are compatible with extrusion.


Michael Landers

Which alternative sources of raw materials do you believe have potential for practical application for aquafeed extrusion?
ML: In our applications laboratory we have already gathered a great deal of experience in product development. Particularly with meal and groats from legumes - not just soy, but also peas and lupines. Or greater use of classic sources of protein and carbohydrates such as corn, wheat, and rice. In view of the world nutritional situation, these can be used more efficiently as aquafeed than for feeding domestic animals. And considering the limited amount of acreage available for vegetable raw materials, byproducts from cereal grains should be investigated as ingredients for aquafeed. For example, I'm thinking here of cereal brans from mills or corn gluten from the starch industry. Other obvious applications are marine plants such as algae or kelp as high protein sources of nutrition for fish farms: Here, it would be possible to clarify on a laboratory scale which percentages in a fish feed mixture are suitable for extrusion or how this can be optimised technologically.

JF: Insect proteins provide one perspective for research and development in the area of aquafeed. At the Brabender applications laboratory, we have conducted our own tests with the objective of replacing fish meal with insect protein consisting of Hermetia illucens (black soldier fly) as a raw material. Initial results are quite promising: In terms of the rheological parameters for extrusion as well as the nutritive feed properties of the extruded products, regardless of whether in pellet or ground form. Particularly in the East-Asian markets, I see good perspectives for this, because tradi-tional dietary customs do not have reservations regarding use of insects in menus.

What can the new TwinLab do for lab scale extrusion?
ML: Well, I could go on for hours about that. But I want to emphasise two main arguments for practical product development with laboratory extruders such as the TwinLab instead of experimental manipulation of the production process. For one, you can vary your application ideas in a wide variety of ways with regard to raw material, formulation, extruder configuration, and product. Secondly, you have the option of establishing methods for measuring your quality parameters in advance from the raw material to the final product. With a width of 60 centimetres, our new TwinLab also fits in even the narrowest of laboratories.


Application technician Julian Foerster with the new TwinLab 20/40 twin screw extruder
Image credit: Brabender

JF: The range of applications focuses mainly on recipe and product development or serves for optimisation of production processes. The new TwinLab is a laboratory-sized twin screw extruder. We have used it to test products with a wide range of shapes, colours, and flavours. During development, it was important to us to be able to adhere to realistic processing conditions. This reduces costs for our customers and is consistently quality-oriented. You require significantly less time for your tests, save on material, and have almost no product wastage. And last, but not least: In everyday production, you do not need to worry about any negative effects to your ongoing quality management system. This allows a return on investment to be realised easily at the company.

Where do you see application-related advantages for product development?
ML: Along the length of the liner, four heating and cooling zones provide optimisable temperatures in every process area. Screw speeds of up to 1200 revolutions per minute offer users great flexibility with regard to specific mechanical energy, called SME for brevity. As a twin screw extruder, the TwinLab allows processing of a wide variety of raw materials, as well as analysis of their viscosity and plasticity characteristics. This is because all conveying, kneading, and mixing elements can be configured individually depending on the process sequence. The module design allows variable con-figuration for product simulation with different shear forces, making the device suitable for highly varying applications. And finally, I would like to mention one more important feature for everyday use in the laboratory: The process unit is separated horizontally and can be folded up vertically – which only few comparable models on the market offer. This not only allows for visual evaluation of individual processing steps, but also provides for convenient screw removal and fast cleaning.


Depending on the application, the screws for the TwinLab-F 20/40 can be configured individually with
conveying, kneading, and mixing elements.

JF: For aquafeed applications, we have produced primarily cylindrical pellets, or expanded products with the round die head – and an additional cutting device. The four upper and two lateral metering openings on the TwinLab also allow liquid or granulated additives such as oils, vitamins, and mineral concentrates or colours to be fed in. For example, I'm thinking here of omega 3 fatty acids or carotenes, which are of enormous importance for aquafeed producers and their suppliers. In the area of research and development, there are many cooperative projects between science and industry, which Brabender is proud to support the aquafeed of the future with its extrusion-related expertise. But even more: We would like to invite customers to visit our Customer and Technology Centre in Duisburg and see the capabilities of our lab-scale extrusion and experience the new TwinLab in operation for themselves.

2nd Farm and Food Integration Seminar
As China enters a new era, the structure and ecology of Chinese Animal Production are undergoing profound changes. The same goes for the Breeding and Aquaculture industries: as public pays more and more attention to what they consume, the industry must become the foundation that guarantees food safety to the general public, as well as promotes the coordinated development of the national economy. But this road to transformation will come with its own challenges.

After the successful launch of the first Farm and Food Integration Seminar (FFIS) at VIV China 2018, the much anticipated second FFIS will be held this year at the VIV Qingdao 2019. As a key converging point for the latest developments and innovations within the agriculture and animal production sectors, the seminar aims to explore market trends within food animal production, block chain and new retail initiatives, and ways to develop the food sector and food animal production value chain.

With the presence of leading enterprises in the industry engaging with the audience, FFIS will be a comprehensive platform where the exchanges of new information, innovations and connections will result in the accelerated and healthy development of the Chinese food animal production industry.
