Part of the Kahl Group, Amandus Kahl provides mechanical engineering for the future. Founded in 1876,
it manufactures feed mill machinery including pelleting presses, extruders and turn-key plants, and works
closely with research institutions and universities as well as its international customer base.
Looking forward to 2014: fish feed plant set into operation in the Maghreb
After extensive market analysis Amandus Kahl has been selected as a partner for the company Rafaha Aquaculture in Tunisia.
In addition to the process and plant design for the complete line, Kahl provided support regarding the basic formulas and the raw materials to be
used, as well as intensive training of the operating personnel. The factory is equipped with the latest Kahl process technology, the core of which
is the extrusion system with the Kahl Extruder OEE and the process control system ESEP.
In the production process, the raw materials undergo the process steps of weighing, fine grinding, mixing, extrusion,
drying, vacuum coating, cooling and packaging. In the first expansion stage, the factory has a capacity of 25 000 tonnes
a year. Sinking, slowly sinking and floating products in various shapes and sizes can be produced.
The formulas tailored to the requirements of the sea bream are characterized by a low starch and high protein content. Particularly
in the area of conditioning and extrusion, Kahl process technology allows them to react to the demands of the local raw materials.
Shaping and adjustment of the pellet density are realized in the extruder type OEE. This machine is equipped with the
hydraulically movable die which is typical of the Kahl extruder. It allows the extruder to start
with open die, which reduces waste and makes the critical process start and stop very easy.
Due to the automatic opening of the die, a die change can be completed within 120 seconds.
This provides additional convenience; in particular since fish feed production typically requires
a variety of different pellet diameters. At the same time a high level of plant availability with a
low downtime results from the rapid die change.
An all-encompassing modernization package could be implemented in the periphery of the
vacuum coater. In the light of continuous quality monitoring of the finished product, a new
software system for batch traceability was installed. It allows much greater transparency in
the production process, with the storage of more than 1 000 formulae and the retracing of

Pegasus Vacuum Coater
One of our famous products is our Pegasus®
Vacuum Coater, intended for everyone who wishes to manufacture
pelleted and extruded products in accordance with modern production specifications. It allows our clients to create a
vacuum environment for their production process and to deal effectively with a very wide range of future challenges.
It is possible to coat or spray each pellet with precisely the right amount of powder or liquid such as pre- and probiotics,
vitamins, enzymes, oils and fat, which is homogeneously distributed deep into the pellet. The vacuum core coating system
for basic, premium and super-premium products, with hygienic design (heating system) averts salmonella risk. During
the production process a robust protective layer is applied to each pellet, which prevents the pellet from breaking or
crumbling and conserves valuable ingredients contained in the pellet. In combination with the Hamex®
Mixing technology we supply innovative process equipment with more added value.
Partnership and good feedback are the key drivers to share know how and create more added value and innovation.
We are introducing Lean Six Sigma Methodology for more efficient production and quality improvement, with
fewer components and less intermediate storage, to reduce contamination risks. For example, gravity is used instead
of pneumatic conveying at initial infeed to a process unit.

Leiber brewers’ yeast products - natural power for reliable
Aquaculture has faced a tremendous and persistent boom over the past decades,
accompanied by an intensification of production. In today’s intensive and expansive
modern aquaculture, fish and shellfish are often subjected to a plethora of various
stressors in their living environment. A chronic stress response is generally believed
to suppress or dysregulate immune functions and makes the organism more
susceptible to pathogens with the eventual risk of causing diseases. Therefore, the
famous phrase “prevention is better than cure” takes on more and more significance
in today’s aquatic animal husbandry.
The multibiotic action of the Leiber products used in aquafeeds is an important
contribution to animal health and performance by prophylactically strengthening the
animal against those stressors in aquaculture husbandry. Leiber’s key products for
Beta-S – a highly purified (1,3)-(1,6)-ß-D-Glucan for strong,
MB40 – Mannanoligosaccharides (MOS) for gut protection and health
Yeast Autolysate - Nucleotides for optimal cell regeneration and cell repair
In 2014 it will be 60 years that Leiber has supplied high value brewers’ yeast
products under the “Made in Germany” banner throughout the world. With two
locations in Lower Saxony, Germany, as well as additional production facilities in
Poland and Russia, Leiber’s over 160 dedicated specialists manufacture brewers’
yeast products and yeast extracts of the highest quality standard. The certification
with the ISO 22000:2005 standard in 2013 highlights this quality of production.
Leiber’s focus on supporting the aquaculture industry has been increased by the staff
reinforcement with Mr. Holger Kühlwein as the Key Account Manager for aquaculture
in April 2013. His responsibilities include among other things supporting and expanding
existing markets, recruiting new sales partners and the individual scientific support.
Lipidos Toledo SA (LIPTOSA) is a Spanish company
specializing in the production of nutraceuticals,
phytobiotics and other solutions for aquaculture.
Liptosa offers a wide range of additives: growth
promoters, hepatic protectors, antiparasites, attractants, chelated minerals, antioxidants and
binders – all of them designed specifically for aquaculture with the aim of improving the health
status and productivity of fish and shrimp farms.
This year Liptosa has introduced additives in new countries, making significant efforts to discover
commercial opportunities in new places, and for new kinds of production systems.
The Chinese market deserves a special mention with its diverse aquaculture and farming of new
species, which always means new opportunities. Liptosa is trying to focus on additives with high
likelihood of success, such as growth promoters and attractants.
South American aquaculture is another interesting market for Liptosa. Salmon, tilapia and shrimp
are all species that can take advantage of our additives, namely phytobiotics with antiparasite
functions, growth promoters and hepatic protectors.
Thoughts for 2014
Currently Liptosa additives are marketed in all countries with significant aquaculture production
and technology. Next year our aim is to continue with the promotion of natural solutions as the
best way to make aquaculture healthier and more productive.
Our company firmly believes in a future where it will be possible to have sustainable aquaculture
for the whole world. Our products intend to give efficient and profitable solutions. Indeed to
face problems before they appear is ‘the best tool, applied in the right way’.
In aquaculture there is still room for improvement. Liptosa has an expert team of professionals
in fish nutrition and production in order to provide effective solutions to its clients.
In 2014 we’ll continue designing new additives and working on new developments, especially in
the field of antiparasites and attractants.

ALWAYS CHANGING TO MEET CUSTOMER NEEDS
Back in 1935, when Wenger was established as a local manufacturer of mixers and feed milling
machinery, the company’s main objective was to add value and palatability to low-quality feed. Today,
as the world’s leading supplier of aquatic and pet food processing systems, Wenger is helping customers
meet a new, more timely list of objectives, like increasing production rates,
lowering energy costs and expanding viable recipe options. In one year alone, Wenger introduced 23
new innovations and was issued 11 new patents in response to rapidly changing needs in the industry.
Available in both single screw and twin screw configurations, Wenger extruders boast
capacities as high as 22 tonnes per hour. Two new innovations - Wenger diverging cone
screws and oblique die technologies - make extrusion the superior choice for production
of even high capacity micro aquatic feeds.
