Steffen explains his
system as working on simple
principles. Because it uses
no supplementary, heated
air, he calls it “chill
curing,” and the name of his
system is Harvestall. He
defends the principle of
using natural air, claiming
that forced hot air blown
through the bin can damage
quality and could encourage
spoilage. His reason: the hot
air forced through the stored
com will take on moisture in
the lower portions of the bin,

but as it moves upward, it
pools and its ability to 1 hold
.moisture is rPduced. Hence,
the air releases some of its
water near the top of the bin
and a moldy layer of cbm
could develop becauseof it.
‘ Simply stated, Steffen
considers his system to be
parallel to the old idea of
letting the air dry com
naturally in long, narrow
sheds with slatted sides. No
forced, heated air was
necessary with those
structures, and, according to
Steffen, it isn’t needed in
modem bins either.

The key, he says, is air
movement. Acknowledging
that natural air movements
can’t do it, he says the trick
is "to force enough air
through the stored drop. But
the air isn’t heated It’s
regular outside air. Even
though the cold air of Winter
• doesn’t have much moisture
holding capacity, Steffen
claims it’s sufficient on most
days. If the air is already
pretty well saturated with
moisture, (i.e. rainy
weather, fog, etc.) then
infrared lights aTe used to
dissipate the moisture from
the air that is being used in
the chill-curing process.
Steffen, who is in part
nership with his brother,
Vince, markets his product
under the Harvestall brand
name. The term “chill
curing,” is a registered
trade mark. Although the
Harvestall Company was
founded in 1958, the Steffens
are only now gaining at
tention in the market.
Higher energy prices have
been partially resposible for
that development. The
Harvestall unit requires no
fuels for heat production. Its
only requirement is elec
tricity to power one or more
fans, plus a series of infrared
lightbulbs.

ceptability hasn’t been

Steffen told his audience. His
firm has been suspected of
fraud and was under in
vestigation tor more than a
year by the Minnesota,
Agricultural Extension
Service. Steffen says he has
been cleared of those
allegations. A report from
Minnesota, however, isn’t in
full agreement with
everything Steffen claims.
In a newsletter from the
Agricultural Extension
Service of the University of
Minnesota, professors D.R.
Hicks, H.A. Cloud, and L.L.
Hardman summarize:
“Based on research
evidence and an analysis of
the processes involved in the
moisture content reduction
of shelled com, we conclude
that a dry weight gain in
crease in the amount
claimed by Harvestall in
their ‘Chillcuring’ process is
not possible. In fact, the
research evidence indicates
that when shelled com is
subjected to the en
vironmental conditions that
exist in a Harvestall
‘Chillcuring’ system there
will be a dry weight decrease
because of respiration ac
tivities of grain storage fungi
existing in shelled com.
Hicks is a professor of
agronomy and plant
genetics; Cloud is a
professor of agricultural
engineering; and Hrdman is
an associate professor of
agronomy and plant
genetics. The three reported
their findings in a newsletter
