Appendix A: Grain Drying Operations
Table A-6 Description of common grain cooling processes (cont'd.)
Cooling process Description Advantages Disadvantages
Combination drying Hot grain is discharged
from the dryer at a
moisture content that is
2% to 3% above its
target, placed in a nat-
ural air or low-tempera-
ture drying bin where it
is immediately cooled,
and then stored.
• Allows each
dryer type to
operate at their
highest level of
efficiency.
• Low-temperature
drying bin maxi-
mizes grain
quality.
• Requires addi-
tional bin dryer to
complete the
drying process.
• Increases risk of
grain spoilage if
hot grain is trans-
ferred to the bin
dryer with a mois-
ture content that
is too high for
natural air or low
temperature
drying.
• Requires more
management
time than any
other cooling
process.
