H
ygienizing and grinding by roller mills is an ideal approach for the production of animal feeds. In order to
maximize the feed quality, it is necessary to give consideration to several criteria in selecting the number of rolls and
their corrugations (fluting).
Like any other markets and industries, the feed manufacturing industry is subject to continuous changes. Customer
needs, market changes, new legislation, and striving for optimization are constantly keeping plant suppliers in motion.
CONSUMER BEHAVIOR CHANGES
Various scandals that have attracted attention in the food processing industry over the past few years have led to an increasingly critical consumer behavior. The world of politics has also
responded to these incidents. It has issued new regulations and
directives and defined targets for the feed markets or stiffened
existing ones such as open declarations, separate production
lines, a ban on different raw ingredients in feeds, etc.
Legislators' responses have triggered innovation and capital
investments in the field of animal feed production which were
long overdue.
Numerous production managers and company operators
have seized this opportunity to launch new and improved
products. For example, no major poultry producers today will
think of feeding anything but hygienized feed to their animals.

Double or triple roller mills offer a
number of benefits in grinding raw
materials
Today, hygienizing is no longer achieved by brief heating of
the poultry feed during a few seconds, but by carefully elaborated complete solutions.
THE RIGHT COMBINATION
In the assessment of poultry feed quality, it is not only the
design of the hygienizing system that plays a role; the feed
texture is also crucial. Poultry producers prefer a feed meal
with the coarsest texture possible but still fine enough to allow a good pellet to be produced. In practice, the best poultry
feed qualities obtained today use a combination of grinding by
roller mills to satisfy the specific needs of poultry and stateof-the-art hygienizing solutions.
When taking a closer look at the success factors involved,
you will find that it is important to assess the overall concept
applied and not merely a small section of the process. You
can only speed across the countryside in your Ferrari if you
master the vehicle and the roads are unobstructed and in a
