AND THEIR
ROLE IN
SUSTAINABILITY
Bühler's Dirk-Michael Fleck discusses how new
grain processing solutions benefit the world
by Arvin Donley
A
s a rule, grain generally is used to make flour. But
by using specifically adapted grinding and separation
processes, other products such as starch,
protein, fiber and germs also can be obtained from different
types of grain. These semi-finished products form the
basis for a number of end products, including modified
starch, glucose, alcohol, gluten and organic fibers.
The Milling Solutions Biorefinery Segment of Bühler is
specialized in designing and building the plants for manufacturing
intermediate products such as these. Other business
units offer solutions for the downstream value chain.
World Grain recently interviewed Dirk-Michael
Fleck, senior adviser, biorefinery, in Bühler's Milling
Solutions Segment regarding new developments that
have occurred in the biorefinery sector.
WG: What is the difference between engineering and
building a flour mill versus a starch mill?
Fleck: Comparing a flour mill with a starch mill is like
comparing a road system of a large city with an intercity
highway. Both are roads, but whereas one is used for
local transport services, the other is a high-speed link
between two cities. In the same way, while a flour mill
needs to be able to produce different qualities and quantities
of flour, a starch mill must be as simple and robust
as possible in order to produce consistently a specific
quality of flour at high capacity.
WG: What does that require in terms of design and
operation?
Fleck: A starch mill must be designed to fit perfectly
into the operating environment of a highly modern
biorefinery. Upstream and downstream processes must
be seamlessly interlinked, and when it is in fully automated
24/7 operation, the mill must continuously
supply a constant product quality for the downstream
process. This is particularly important because starting
and stopping wet separation and biotechnological processes
cause great expenses and losses. The mill must
be fully automated and operate safely at high capacity
to achieve economic efficiency. A medium-sized
starch mill, therefore, has a capacity of 800 tonnes per
24 hours.
WG: What does a starch mill produce?
Fleck: Starch mills usually produce one main flour and
several secondary products such as bran from grain. The
flour has to meet specific requirements so that, in the wet
separation process that follows, starch, protein and other
high-quality products can be obtained as efficiently as
possible, with high yields and high levels of purity. In the
next step, semi-finished products such as starch, protein,
