DRYER MONITORS
Seed drying involves the transfer of
moisture from the seed to the air around
the seed. To accomplish this you must
raise the temperature and lower the relative
humidity of the air and pass it through
the seed mass. If the temperature of the
air is very high, the drying process may
be too violent resulting in damage to
the seed. Too low of temperatures will
delay the drying process often resulting
in damage caused by disease, insects and
excessive respiration.

| Ideal corn seed
drying temperatures will vary depending
on the genotype, harvest moisture and environmental
conditions but typically range between 95º
F and 113º F. The higher the initial
moisture content, the more susceptible the
seed is to drying damage. Therefore it is
recommended that corn seed with 35 to 40
% moisture be initially dried at temperatures
less than 107º F. When moisture content
is lowered to 20% or less, drying temperatures
may be increased up to 113º F to complete
drying to the desired seed moisture content
of 12 to 13%. |
 |
| Regardless of
the drying system used it is critical to
regularly monitor drying temperatures, relative
humidity, airflow rates, and moisture content
of seeds in different parts of the bins.
Finally, remember that corn inbreds have
a range of sensitivities to drying temperature.
Studies have found significant differences
in the effect of drying temperatures on
the warm and cold germination of different
genotypes. |

| The Dryer Monitoring
System allows you to monitor and control
a number of parameters, which affect seed
drying, and drying rates. The system will
monitor and collect temperature, humidity,
air direction and air speed. From this data
you can control the burner, predict drying
rates and monitor the dryer so seed is not
damaged from drying too fast or too slow.

|
| The remote monitoring
feature allows the operator to monitor all
the parameters from a central location or
at home. For more information or a demonstration
at your facility please contact
us. |
