For every bale of cotton ginned approximately 800 pounds of seed must be handled from beneath the gin stands and placed either in a temporary or long-term storage facility. For long-term storage, aeration is necessary to reduce seed temperature and moisture, and minimize mold growth and insect activity within the seed.
This paper briefly describes structural and aeration requirements to maintain seed quality during storage. A complete discussion of design criteria is reported in the USDA Marketing Research Report No. 1020, "Aeration of Cottonseed in Storage" (Smith, 1975).
The bulk density of gin-run cottonseed averages about 25 lb/ft3 and requires about 80 ft3 of storage space per ton
Long-term cottonseed storage facilities must be equipped with an aeration system
Many types of buildings can be used to store cottonseed at gins
Aeration ducts distribute air through the seed mass
An air manifold and supply lines distribute air between the fan and the aeration ducts
Most aeration systems are designed with downward airflow through the cottonseed
Design a storage and aeration facility for 1,200 tons of cottonseed
The lobed blower normally used to handle cottonseed from the seed auger from inside the gin to the temporary house can usually be used to transport seed to a storage building
Ginners have successfully stored dry seed in all types of buildings for short periods
Usually no additional aeration is necessary once the seed has been cooled to the desired temperature
