2.
Wet grain will remain relatively cool due to moisture evaporation from the kernel, however dry
grain will warm to the drying temperature.
3.
The drying front moves from the base of the bin upward. When operated as a batch system and
when a stirring machine does not reach the floor, significant over drying can occur at the base of
the bin.
4.
When drying grain and focusing on kernel quality, use as low a plenum temperature as possible.
Note: Do not automatically set the plenum temperature at the maximum
recommendation
.
5.
When the grain is nearly dry, reduce the plenum temperature to complete the drying. This will
reduce the quantity of cracked grain generated and reduce the fire hazard.
6.
When drying sunflowers, exercise caution because sunflowers are very flammable. Do not
exceed the temperature recommendations. Also, be aware that the chaff from sunflowers is
very flammable. Good housekeeping in the plenum chamber and around the bin is essential.

commercially). For seed crops, do not exceed 110°F (43°C), except for pinto beans
do not exceed 100°F (38°C).
