with, but it takes some time to get
terms settled with several units of
government involved."
The final location selection was
driven principally by logistical advantages, Mr. Siemer said.
"Transportation as much as anything
was the reason we settled on this site,"
he said. "There is excellent access. A
lot of the places we looked at were in
industrial parks, but to get to those industrial parks you had to go through
residential areas. This site is right on a
highway, three-fourths of a mile from
Interstate 74 and close to the Ohio River bridge on the beltway, I-275."
This access, west of Cincinnati, is far
more attractive than what lies to the
east, Mr. Siemer said.
"Traffic on I-75, through downtown,
made that area undesirable," Mr. Nagel added. "The bridge there is the
poster child for decaying infrastructure in the United States."
Rail access to the mill is on the
Brookville line of the Indiana & Ohio
Railway, a short line that is part of
Genesee & Wyoming Inc. The IORY
serves the metropolitan areas of Cincinnati, Columbus, Lima and Springfield in Ohio.
"The G&W is a very successful and
reputable company, but IORY Brookville
line has not been heavily used," he said.
"So developing a relationship with
them has taken some time.
"Right now we are starting up a
flour mill and they are restarting a

line, and it will be profitable for both
of us if everything works as it should."
The first rail cars of wheat did, in
fact, arrive in mid-July.
The mill will grind 100% soft red
winter wheat, Mr. Siemer said, describing Siemer Milling as "more familiar with the soft wheat side of the
business (the company grinds limited
quantities of hard winter at its Hopkinsville mill). The mill can make
10,000 cwts per day, and we hope to
increase that in the future, as we have
at our other mills. Maybe do some
hard wheat, too."
Grain intake at the mill accommodates wheat delivery by rail or
truck. A precleaning system utilizes
a Bühler TAS LAAB cleaning, grading and aspirating system. The device is made by Bühler's integrated
affiliate company - Schmidt-Seeger.
The German business was acquired
by Bühler in 2010.
The purpose of cleaning grain prior
to putting it in silos is to optimize the
storage life of the grain, enhancing
the quality of the product to be milled
and, ultimately, the end product.
"TAS is a high throughput system,"
Mr. Maheshwari said. "Typically, you
have just an aspirator. TAS separates
better, helps remove sand, chaff, dirt
and corn. It's a big improvement from
most precleaning set-ups."
The Whitewater Mill has 960,000
bus of grain storage, equating to about
six weeks of grind.
Utilizing a differential portioning
Transflowtron scale system at the base

of the grain bins, drag conveyors bring
wheat from the elevator into the mill,
passing over a drum magnet at the
outset. The cleaning house features a
Bühler Vega/Venta grain cleaner-classifier, Sortex color sorter, aspirators,
and scourers. The sorter catches dark
defects (such as discolored grain),
light defects (partially broken grain)
and infrared defects (fusarium).
Mr. Siemer observed, "The Vega
Venta was developed to replace the
conventional 'workhorse' separator. With the separator, the big stuff
stayed on the top, the little stuff went
out the bottom, and the grain stayed
in the middle. The Venta/Vega can
separate more finely. If the crop year
is bad and grain has been damaged in
different ways, you can take out different fractions."
Mr. Maheshwari added, "The Vega
Venta system is more efficient with
greater throughput. You can have
greater segregation. You can clean
your grain with a different sizing."
Ruedi Weiss, director of sales - grain
milling, at Bühler, said a major point of
difference for the Vega/Venta system is
that it has four times the screen area of
the traditional separator.
"That allows us to go very small in
the screen size and remove much more
foreign product," he said. "The larger
surface also makes it more effective."
A new model Sortex color sorter is
more effective in removing vomitoxindamaged kernels, according to Bühler.
"We will always be compliant with
F.D.A. advisory levels, but this system
