New scientist at IFF

Dipl.-Ing. (FH) Georg Franke studied Physical Engineering at the University of Applied Sciences in Brandenburg. His diploma thesis led him to the Leibniz Institute for Agricultural Engineering and Bioeconomy in Potsdam (ATB) where he was research engineer and concerned with treatment technology, storage and postharvest technology. Another emphasis of his work was to test and to develop drying processes and to simulate particle movements by Discrete Element Method (DEM). From actual issues of bulk solids handling, he developed a newly discharge device to control the residence time distribution. The results take part of his continuing dissertation at the Chair for Mechanical Process Engineering at Otto-von-Guericke-University Magdeburg. Since Mai 2017, Mr. Franke is part of the scientific staff at IFF and focuses on process engineering challenges in production of compound feed.

Review IFF Practical Course “Pelleting of compound feed”

On 28 and 29 January 2014, the practical course “Pelleting of compound feed” was organised with 36 participants. The participants came from the compound-feed and additive as well as machinery industry.

The two intensive days were affected by the essential aspects around pelleting of compound feed. The main topics were evaluation of the pressability of compound feed, operating parameters of the pellet mill, all relevant processes before and after pelleting like conditioning and steam generation as well as the cooling process. Furthermore the pelleting of renewable raw materials was discussed. Further topics were additive stability during pelleting as well as wear and energy saving potentials at the feed mill.

Practical exercises at the test facilities of IFF deepened the contents of the lectures. The participants had a closer look at the pelleting and cooling process. The evaluation of the pellet quality of different pellet samples was demonstrated. Lively discussions about relevant issues of compound-feed production completed the course.

In summary, it was a successful event for the participants and the IFF-institute.

Due to the high demand this course will be offered in the next year again.

From 7 to 8 October 2014 the course will be repeated exclusively in English language. Please give us your registration either by phone +49 (0) 5307/9222-0 or e-mail iff@iff-braunschweig.de.


Key Technologies for SME                                                                                      

In January 2013 the AiF (German Federation of Industrial Research Associations) published a call to submit idea sketches in the frame of “Key Technologies for SME”, which have to be support by at least two research associations and have to be processed by more than two research institutes of different profiles.

IFF and its research institute participated with two own drafts, in one further approach IFF was a partner.

Out of 45 submitted contributions only 6 were selected by the reviewers for preparation of a full proposal. One of these is IFF's “Setup of a functional model for industrial production of insects as fat and protein source for feed stuff”. Partners of the Research Institute for Feed Technology are Bremerhaven University of Applied Sciences (Chair for Food Chemistry), University Erlangen-Nuremberg (Chair for Fluid Mechanics) and University of Göttingen (Chair for Animal Nutrition).

IFF Colloquium “Contrary to public perception – Why our feedstuffs are safe!”

As part of the annual general meeting of IFF the colloquium took place on 12 June 2013. 38 participants from the compound-feed and mineral-feed production and the machinery and plant industry attended the event, which formed a counterbalance to catch lines in the media. A scientific view was put on existence, analysis and management of microorganisms and mycotoxins in raw materials and feedstuffs. Among others it was shown that unqualified methods of analysis can lead to an incorrect public perception. Legal requirements offer a high diversity in interpretation concerning the fulfilment of individual responsibility, which follows in insecurities concerning necessary actions. Finally, it was shown, that at present many alternatives are at hand to minimise the occurrence of microorganisms and mycotoxins. Although there are interesting approaches for further development it has to become clear in public, that in processing of natural products like grain a safety of 100 % cannot be obtained.

Joint Seminar of IFF and GenoAkademie “Premix/Mineral Feed Production – Why is Precision in Demand?“

On 4th and 5th of June 2013 in Rastede the first joint seminar of IFF and GenoAkademie took place on premix/mineral feed production. 27 participants, both experienced experts and new comers, from premix and mineral feed production and from equipment manufacturing attended the event.

During both days the most important aspects of premix and mineral feed production where covered. The first day started with topics from live stock holding. Then a practical experience report dealt with typical errors within the production process. The influence of material characteristics onto processing closed the first day. On the second day sampling and possibilities to reduce cross contamination were discussed. An important focus was put on dosing. Following aspects of correct composition of mixtures and alternatives of agglomeration an overview of legal demands closed the seminar.

All in all it was a successful seminar with satisfied participants.

The seminar will be offered again in 2014.


11.03.2013 - 16.03.2013:


IFF Intensive Course “Basics of compound-feed production“

From 11 to 16 March 2013 the intensive course “Basics of compound-feed production” took place at the Research Institute of Feed Technology of IFF in German language. For the first time it was reduced from formerly ten days to six. 21 participants representing feed producers and manufacturers from Germany, the Netherlands and Austria attended the course which were not only experts but also newcomers as well as people seeking career changes.

The contents of the six days were mainly characterized by all relevant aspects considering compound-feed production. In this case feed technology covered the classical topics storage, transport, dosing, grinding, mixing, pelleting, hygienisation, cooling as well as steam production at a feed mill.
Further subject areas were quality management and product safety as well as measurement techniques, plant safety, environmental protection and feed law. Also related subject areas such as feed science/animal nutrition and business economics were emphasized. The manifold theory was underlined by exercises and demonstrations at the laboratory and pilot plant.

The test at the end of the week was passed by all participants successfully so that the proof of technical expertise towards authorities could be issued to all of them.

All in all it was a successful course with ambitioned participants who felt themselves “in good hands”.

This course will be repeated in 2014.


Technical Seminar "Economising with energy – Potential savings, energy management systems and application according to § 41 of the German Renewable Energy Law”

The considerable rise of energy costs during the last years in the meantime creates high economic stimulations for a reasonable energetic economizing at feed plants. For this reason the director of the institute Dr. Benning could welcome 30 participants and speakers at the IFF Research Institute on 14 February 2012 for deepening their knowledge and discussion of this topical subject.

A wide subject area could be covered with the focal points current legal developments in the energy-tax law, application in the frame of the “special equalization rule” for electricity intensive companies according to § 41 of the German Renewable Energy Law and presentation of precise steps for saving energy in compound-feed plants.

Another focal point of the seminar was sent on the presentation of energy management systems which in future will be an indispensable condition for getting tax reliefs and for a continuous improvement process.



International Workshop “Safe Feed for Healthy Food“

On 24 November 2011, the international workshop “Safe Feed for Healthy Food” took place at the Research Institute which was organised by by Prof. J. Zentek, Freie Universität Berlin, Germany, Prof. P. Häggblom, National Veterinary Institute (SVA), Uppsala, Sweden, and Dr. Alexander Feil, IFF, Braunschweig, Germany. 23 participants and 11 speakers took active part in the event.

From the view of the compound feed production especially mycotoxins and salmonella represent a significant risk for the animal health and because of the carry over effects also for the human health. Cases of damages may lead to essential economic losings for the compound feed producer. Optimised operative strategies concerning the handling with these contaminants require beside the early identification an efficient decontamination. This assumes an effective system of control and monitoring including suitable methods of analysis, an adapted information management and founded knowledge in procedural possibilities and limits.

The workshop includes the following findings of the FP6 research project “BIOTRACER IP”, presented by international accepted experts:

•    Hazard assessment for imported and local raw materials concerning the contamination by aflatoxines, ochratoxines and salmonella
•    Improved measures of sampling and analytics during the process for these contaminants.
•    Development of a simulation tool for salmonella.

The workshop was supplemented by the experiences of the Research Institute of Feed Technology concerning the effects of technological decontamination methods including the acid application.

The participants were especially impressed by the video “Sampling For Contaminants In Animal Feed” which was established in the frame of the research project. It illustrates the latest findings on the sampling of mycotoxins and salmonellae. The video can be found at YouTube.

Besides the presentation of the newest scientific knowledge the workshop offers the opportunity of important and informative networking and exchanging of ideas between industry, monitoring devices and science.






IFF Workshop "Appropriate storage and use of liquids in the compound-feed production”

On 27 September 2011 the IFF Workshop concerning the subject “Storage and use of liquids” took place. Because of the various common but also alternative liquids as well as different process and plant parameters, it arises a wide range of subjects and applications concerning the use of liquids in the compound feed production: Beginning with the receipt and storage of liquids and ending with their application on finished products.
Furthermore, measures are required to ensure the quality in the production of liquid single feed stuff. These measures should guarantee a traceable documentation of purchase of the raw materials, the production and processing until dispatch and vice versa.
To cover this range of subjects, the workshop had been designed by contributions of well-respected speakers of the economy, who gave important advices of the daily work to the 34 participants about the following subjects:

•    Planning and building of plants for storage purposes
•    Dosing of liquids
•    Material properties
•    Management of production and quality
•    Technological aspects of applications of liquids in mixers
•    Possible applications of a continuous vaccum coater

The workshop was completed by the presentation of the results of the IFF-research project regarding the addition of liquids in the main mixer as well as the property of glycerin concerning the technological handling in compound-feed formulations.
Additionally, the Fraunhofer Institut for Process Engineering and Packaging IVV presented their research results concerning use of emulsions in alternative applications.

Does the addition of a surfactant affect the pelleting process?
Rainer Löwe, IFF and Richard Oldman, ANITOX Corp.

In times of increasing costs for raw materials and electric energy and declining margins numbers of feed millers have commented that they are in search of cost saving options especially regarding pelleting. Of major concern are specific energy demand (kWh/t) and moisture losses in finished pelleted feeds because this means immediate mass loss. Trials at IFF Research Institute of Feed Technology, Braunschweig, Germany should give respond to the question if pelleting aids like surfactants can make a contribution to solve the problem. Read the whole article of Rainer Löwe and Richard Oldman.

Mrs. Olivera Djuragic, research assistant at the Institute for Food Technology, Research Center for Feed and Animal Products, Novi Sad, visited IFF

Her short review

As a part of the project “FEED-TO-FOOD” (FP7-REGPOT-2007-3 "Reinforcement of Feed to Food Research Center at Institute for Food Technology of the University of Novi Sad") which includes the exchange of research experience, the first longer visit to IFF was from August 16th to September 11th. In the period of the visit, I was introduced with the works and almost all activities of the institute, including laboratory work and some pilot plant work which are carried out under current projects. I felt all the time as a member of the collective because I had opportunity to be present at all institute meetings concerning work at last and future weeks. Also I got an opportunity to present my research work as well as the work of my institute, particularly the department of Feed and Animal Products. All the time, we discussed about possibilities of further cooperation and possible results which can be published in some journals to get references for future European projects. Main topics were methods used in determination of homogeneity and working accuracy, as well as about some investigations in the area of feed pelleting process and liquid addition. We also talked about the contribution in the current FP7 proposal in area of feed safety and quality and made some comments and suggestions. In the period of the stay, I visited the Friedrich Loeffler Institute (FLI), their facilities and introduced their field of research and also AGRAVIS, local feed producer, who is a part of the Raiffeisen Company. A one-day visit to Hanover Messe on September 8th was aimed to meeting with Dr. Steinkamp from the Deutsches Institut für Lebensmitteltechnik (DIL) and after discussion we established a good base for future cooperation.  

Finally, I can say that my visit was successful and fruitful and that our two institutes can do more in future in the field of feed technology not only as a part of the project “FEED-TO-FOOD” but in the other kind of projects.

Four young researchers from Novi-Sad (Serbia) visited IFF

Within the project FP7-REGPOT-2007-3 "Reinforcement of Feed to Food Research Center at Institute for Food Technology of the University of Novi Sad" four young researchers visited the Research Institute of Feed Technology of IFF. A short summay of the 14-day stay as well as impressions and experiences of the young scientists are compiled as follows: 

With this article we would like to share our impressions about IFF Institute in Braunschweig. We are Bojana Kokic, Radmilo Colovic, Djuro Vukmirovic and Dusica Ivanov, young researchers from Institute for Food Technology in Novi Sad, Serbia, department for Animal Products and Feed Technology. IFF Institute is our associate institute on FEED-TO-FOOD FP7 project, funded by European Commission.

The reason for this two week visit was to participate on basic course “Fundamentals and new developments in feed-compounding technology“, but also introducing with all equipment and physical analysis that are conducted on IFF Institute. The least that we can say is that this visit was useful and that it fulfilled all our expectations.

The course was very well organized. The lectures were focused on practical issues and supported by scientific data that was originally from IFF experiments. We also got some new information about legislations and EU laws, which will help us to understand functioning of European Union better. The lecturers had great knowledge in their areas and they were ready to answer on all of participants´ questions.  

In second week we were introduced with all process equipment, such as extruders, expanders, pellet machines, various types of mills, etc. That was especially interesting for us because of the fact that we have the same devices in our pilot plant, and that we are planning cooperation on same frame work projects in future.

We were also shown physical laboratory equipment and methods which will help us to improve our laboratory and to implement some new analysis. A lot of literature and scientific papers that we also got would show us in which direction our experiments should proceed.

At the end, we could not forget visits to the “Friedrich-Loeffler-Institut (FLI)”, “Burg Warberg”, “Feed Mill Agravis Braunschweig”, “DMSB” International Technical School for Process Construction and Process Engineering, “MEGA Haldensleben” and “Schaumann Eilsleben”. Not less important are contacts that we made with a lot of our colleagues from areas related to feed production.

We would like to express our gratitude to our hosts for hospitality and well organised visit to Braunschweig and we are inviting them to visit our institute!

Substance data base on the dust-formation behaviour of single feeds, additives and feed mixtures

In the frame of the research project “Explosion hazards”, that was made possible with funding from the Federal Ministry of Economics and Technology via the German Federation of Industrial Cooperative Research Associations “Otto von Guericke” e.V. (AiF), a material data base was developed in which investigation results are made available on the dust-formation behaviour under different conditions on basis of the relevant identification of the substances used in the grain cultivation and feed industry.

The selection of the materials are geared to the already available data base (BIA GESTIS-STAUB-EX data base, BGIA - BG-Institute for Occupational Safety and Health) and is a supplementation to the fire and explosion characteristics.

The data base is available with immediate effect and can be supplemented dynamically.
