Solar grain drying not yet practical
LANCASTER - The
potential value of solar
supplemental heat for grain
drying is limited when
compared to natural-air
drying, says Vance Morey,
agricultural engineer at the
University of Minnesota.
Morey was a speaker at
the Fifth Mid-Atlantic No-
Till Conference held here
January 4. More than 1300
farmers and industry
representatives from six
states attended the con
ference.
Except for special
cirumstances it appears that
the justifiable investments
are well below the installed

cost of even so-called “low
cost” collectors. The
justifiable cost per square
foot may be as much as
doubled for collectors tilted
at an optimum angle to the
sun or designed for higher
efficiencies. However, in
most cases such collectors
will have higher installed
costs per square foot, Morey
points out.
“Solar collectors of one
acre or more in size are
required to supply the heat
energy for even a moderate
sized, high-speed system.

peratures needed for high
speed systems are ex
pensive,” he notes.
Morey says the potential
for supplying supplemental
solar heat to in-storage
drying systems appear to be
more promising. The
reasons for this include:
1. The long drying period
(4 to 10 weeks or longer)
provides an extended period
for collecting solar energy.
2. Intermittent periods of
cloudy weather are not a
problem since the gram in
the bin can act as an energy
storage.
3. The high airflow
requirements along with the

low temperature rises mean
that relatively simple and
inexpensive collectors can
be used to collect the energy.
Although the concept
appears promising at first
glance, and many systems
have been tried within the
last few years with the
results pronounced as
“successful,” further

Seed supply surveyed
WASHINGTON, D.C. -
Production of alfalfa and
annual ryegrass seed was
down last year, but red
analysis of the concept is
needed. As moisture con
tents increase, allowable
drying time decreases which
means higher airflow rates
are required. As tem
peratures increase,
allowable drying time
decreases, again requiring
higher airflow rates.
