tory technician with limited understanding of mill operational objectives or an
out of control milling process.
Flour streams with the greatest
changes were C1, C4, C3, R1 and C2
and, of course, Break Bran and Shorts
followed by Pollard (Red Dog) for the
feed streams. These changes, as intended, had a significant impact on flour
yield whether based on wheat to B1 of
total products recovered. A commercial mill would not likely handle such
stream variations or imbalance due to
constraints on roll, sifter and purifier
surface in addition to designed material
handling or conveying limitations. The
Bühler Tandem Laboratory mill is forgiving in this sense.

of observations using the rule of thumb
presented for observations. The 95%
confidence interval for the mean value
reported is so much narrower than the
confidence interval for observations. Mill
performance and customer satisfaction,
however, are based on individual lots of
wheat being milled. Millers have success

and failure based on individual wheat lot
performance and customer experience.
This series presented experiences
with laboratory milling and crop quality assessment. Variations in mill settings impact yield and quality attributes.
Milling and quality results measured on
the same wheat sample show variation

CONTROL AND COMPOSITE SAMPLES
Figure III, page 74, provides product
stream information from the milling of
control and composite samples for 2019
hard red winter wheat in the United
States. The control wheat was harvested
several years earlier and may account for
the slightly higher yield than observed
for the composite samples, which are
milled within several months of harvest.
The control sample averaged 0.49%,
0.11%, and 1.08% more flour from the
break system, R1 and primary reductions
(C1-C4), respectively, than the composite samples. The composite samples'
average secondary reduction (C5-C6)
was 0.75% higher than observed for the
control sample average. These observations combined with composite samples
having greater bran and shorts duster
flour (BSD) and feed stream production
may suggest endosperm is more difficult
to remove from bran in the break system
and is somewhat more difficult to reduce
to flour in the reduction system in freshly
harvested wheat than wheat held for a
longer period of time prior to milling.
No statistical inference is being made
in this report as the composite samples
may be further segregated into low-,
medium- and high-protein sample sets
for further analysis.
Look at the statistics shown in Figure
III of this article and estimate the range
