Ingredient Selection and Extrusion Parameters for Aquatic Feeds

Joseph P. Kearns, Vice President Aqua-Feed Div., Wenger Manufacturing, Inc., USA

Ingredients are always changing due mainly to availability or costs, but there are also variations in ingredient quality.  As many aquatic feeds move towards the use of vegetable and other novel ingredients, the extrusion task at hand is to maintain quality at the higher production rates with lower levels of starch inclusion. When pushing the limits on all boundaries the process becomes a challenge.  Generally the situations can be dealt with - but something usually needs to give. Trends in production methods, both of hardware and running conditions, are allowing for wider ranges of non-traditional ingredients or ones of lower quality. Reviewing ingredient quality and the extrusion process will give insights on balancing the system.    
Joseph P. Kearns is a graduate of Kansas State University and has been employed by Wenger for more than 40 years. He has spent a career watching and being involved in the feed production in the aquaculture sector. He holds nine US and foreign patents on aquatic topics relating to extrusion cooking. He has authored numerous publications on aquatic feed production as well as made presentations around the world.      

Effect of Extrusion Technology on Physical and Nutritional Quality of Extruded Fish Feed

Urs Wuest, Director Market Segment Aquafeed, Bühler AG, Switzerland

The effect of extrusion technology on physical and nutritional quality of extruded fish feed will be addressed. Mr. Wuest will explain the roles of the pre-conditioner, of die design and of density control, a critical variable if fish feed production that  effects pellet buoyancy, floating and sinking characteristics, oil impregnation during the coating process and factory capacity.
Density and SME controllers can help to make floating, slow sinking and sinking pellets. These devices reduce the need for changing the screw configuration and provides control on shear stress, specific mechanical energy and extrusion pressure. The controllers can also be connected to the extruder control system to automatically adjusted and maintain the process conditions to its chosen set-point in order to make aqua feed with a wide range of bulk densities.
Urs Wuest is the Director of the Market Segment Aquafeed at Bühler, Uzwil, Switzerland.  Until 2010, he was responsible for technology and R&D for the market segments Feed, Petfood and Aquafeed. Mr. Wüst worked for more than 10 years in Japan and Korea in sales, engineering and customer service as Manager Feed Technology & Extrusion Systems at Bühler Japan. Prior to that he was Product Manager Food & Feed for analytical equipment at Büchi Lab-technology Switzerland, responsible for strategy, worldwide sales and development of new equipment. He was also Project Manager Feed & Oil Milling at Bühler Belgium, South Africa and Switzerland and Feed milling engineer at the Swiss Institute of Feed Technology (SFT).

Future Possibilities and Demands in Salmon Feed Production

Dr. Mari Moren, Director of Nutrition and Feed Technology, Nofima AS, Norway

The Norwegian government would like to see a five-fold increase on today’s aquaculture production by 2050. A similar increase in feed production is therefore required. Known barriers are the limited access to marine raw materials and incomplete understanding of the salmon’s nutritional requirements. Currently, many “new” ingredients are developed and tested in the search for those that can be viable in terms of availability and cost. The government also says that the growth should meet environmental, social and economic sustainability demands. This presentation will aim to give a view on the future demands in salmon feed production and present possibilities from the viewpoint of a research institute working on R&D throughout the whole value chain in aquaculture.
Mari Moren is Director of Research at the food research institute Nofima. She is responsible for Nutrition and Feed Technology, which is one of the research areas in the Division Aquaculture. This area encompasses research, development and innovation projects along the complete aquaculture value chain, with a special focus on research into new feed raw materials, feed technology and questions related to nutrition. Dr. Moren holds a Ph.D. in nutrition from University of Bergen (2004) and has 15 years of experience in fish nutrition research.


Aqua feed extrusion line optimization. Process automation as key to secure consistent aqua feed quality and cost efficient operation

Nicolai Nexus, Manager of Automation, Andritz Feed & Biofuel A/S, Denmark

Most aqua feed process plants are making a wide variety of specialized feeds with very exact properties in terms of specific pellet size, density, moisture content, and texture. All to be made from a wide range of formulas, and based on feed ingredients of different origin, further influenced by seasonal availability and maturation.

Further most plant are producing the feeds “just in time” to secure freshest possible feeds to the aquaculture farms. This often leads to requirements for frequent changes in products and short runs.

Efficient automation systems for the entire extrusion process line, extruder, dryer, coater and cooler are key to repetitively secure quick start-ups to reach maximum capacity at the desired - and consistent quality and with less dependency from the human factor. Further the process statistics derived from automation systems provides essential knowledge in support of trimming the process line, optimizing line efficiency and costs of production.

On-line connections allows for remote monitoring, best practice sharing, and long-distance support. 

Practical Manufacturing Constraints and Their Impact on Feed Formulation Resource Allocation Models 

Ian Mealey, Head of Operations, Format International, U.K.

Traditionally, feed formulation tools have primarily focused on nutrition and resource allocation decisions as the driver for their output. Issues that affect the actual manufacturing of the feeds designed by these tools have been difficult to adequately incorporate. These issues include weighing constraints, effects of ingredients on quality, throughput and energy use and silo availability. This presentation will discuss optimization techniques that are now becoming available and offer the formulator the ability to more accurately model these aspects alongside nutritional and ingredient purchasing parameters, in a more holistic approach. This capability will inevitably have a positive feedback on the measurement of ingredient value and subsequent resource allocation decisions.
Ian Mealey has 25 years’ experience in the feed industry; first as a formulator within a large UK feed business, and then with Format International. He has worked in a consultancy role for many years and with many different clients around the world in various sectors, for the practical application of formulation software to improve profitability and efficiency in these businesses. Ian is particularly enthusiastic about formulation software’s capability in the area of resource planning and risk evaluation.

Innovating by Experience - Ideas and Cases          

Dr. Olav Fjeld Kraugerud, Manager, Centre for Feed Technology, Norwegian University of Life Sciences (NMBU), Norway

The constraints and challenges of aquaculture open up a lot of opportunities. However cost, combined with the volumes in the sector, create incentives for only incremental improvements. As most needs have been defined regarding EAA and EFA, the floor is wide open to ingredient suppliers because they know what to overcome. Based on all the different variations in the ingredients pool, a new or alternative protein concentrate could potentially be included at the rate of 5 – 25%.  Examples from trials performed with krill meal, gluten and plant meals will be shown. A feed recipe with a diversified protein portfolio could benefit from tailor-made processing. But would this be realistic? Data of such trials undertaken at the Centre will be shown. An exciting new and innovative tool created for feed production will be revealed.
Dr. Olav Fjeld Kraugerud  leads the Centre for Feed Technology at the Norwegian University of Life Sciences (NMBU), Norway. In this role he works with customers in both academia and industry. The challenge of always making feed in new ways leads to innovation, as new demands are imposed on both hardware and processes.   As a previous scientist at the Aquaculture Protein Centre in Norway, Dr. Kraugerud was one of the demanding customers of the Centre from 2004 to 2012. In his thesis, he mainly examined the processing of novel ingredients, especially the carbohydrate fraction, and studied their nutritional effects. He received his PhD in 2008.

Advanced Research Initiatives for Nutrition &Aquaculture (ARRAINA): Fine tuning the delivery

Dr. Jorge Dias, Co-Owner & General Manager, Sparos Lda, Portugal

Results will be presented from the Advanced Research Initiatives for Nutrition & Aquaculture (ARRAINA) project, a European FP7-funded Collaborative Project coordinated by INRA and associating 21 institutions, among which are nine industrial partners. 
The overall objective of the ARRAINA project is develop sustainable alternative aquaculture feeds tailored to the nutritional requirements of the five main European farmed fish species, Atlantic salmon (Salmo salar), rainbow trout (Oncorhynchus mykiss), gilthead seabream (Sparus aurata), European seabass (Dicentrarchus labrax) and common carp (Cyprinus carpio), over their full life cycles, with reduced levels of fish meal and fish oil; and assess the long term physiological consequences by applying targeted integrative tools that accurately measure and predict the effects of alternative feeds on fish metabolism and health. The project is using these tools to develop alternative feeds and novel delivery vectors for early life stages of fish and study the long-term effects of these alternative feeds on metabolism, performance, quality and waste management over the full life-cycle (from egg to broodstock). ARRAINA is also exploring the concept of nutritional programming in fish.
Dr. Jorge Dias will focus on new knowledge generated on the fine tuning of the dietary supply of trace elements in larvae and juvenile feeds, relying on the use of innovative delivery vectors such as microencapsulated and nano-sized mineral forms and a closer look on the interactions among trace elements and other nutrients. Activities on the effect of vegetable ingredients on physical pellet criteria and fecal properties will be discussed. A predictive tool to compare the environmental impact (total, N and P waste) of different feed formulations developed for gilthead seabream will also be presented.     
Dr. Jorge Dias, together with Luis Conceição are the managing partners of SPAROS Lda, a technology-driven SME dedicated to the development of new products and tailored nutritional solutions for the aquaculture market. Jorge Dias has a PhD in Fish Nutrition and expertise in feed technology; feed formulation; the practical use of novel ingredients and feed additives. Prior to SPAROS, Jorge Dias was a researcher at both Academia (INRA-IFREMER, France; CCMAR, Portugal) and Industry (DSM Nutritional Products, France).

Acidifier Concepts in Aquafeed: Technical and Functional Considerations

Tilman Wilke, Product Developer, Dr. Eckel GmbH, Niederzissen, Germany
The concept of acidifiers has been successfully transferred from agriculture feed to aquaculture feed. We want to share our experience on some important technical and functional aspects of this transfer.
Acidifiers as functional feed additives are a well-proven concept in feed for agriculture animals. Acidifiers have the ability to preserve feed, to improve feed conversion and to reduce pathogen pressure. The basic approach is to include organic acids and their salts in the feed. While organic acids are preservatives and are used as such, there is also a high interest in their nutritive value and the impact on pathogen cells and gut epithelial cells. Scientific studies and practical experience in the field have shown that organic acids can improve performance and health in livestock. Although acidifiers are usually easy to handle, organic acids can lead to problems in the feed manufacturing process. When organic acids are used in its reactive form, unexpected exogenous chemical reactions can occur during the mixing process and they can lead so severe corrosion of silos, floorings, pipes, conveyors and roofings. Therefore we have optimized our acidifier formulas to use non-reactive calcium salts of organic acids to prevent this.
Tilman Wilke is a product developer at Dr. Eckel, with a focus on aquaculture feed. His job is to find innovative solutions for our customers’ challenges and to bridge the gap between new academic concepts and practical customer requirements, keeping in mind the global challenges in animal feed production. He studied veterinary medicine until 2009 with a growing interest in the interfaces and borderlines between veterinary science and animal production. After graduation he went to an agricultural faculty to work as a research assistant. In 2014 he joined Dr Eckel, one of the leading feed additive producers in Germany.
