Interpretive Summary:

Technical Abstract: A multi-year study is investigating a mathematical model that predicts the moisture content of cotton as it is being processed in the gin. Data was obtained during the 2014 season at the Midnight Gin in Midnight, Mississippi. The model took into account the temperature and mass flow rate of cotton and conveying air at various locations in the gin, and then estimated the moisture content of the seed cotton. Results showed that acceptable dryer temperatures were used. Dryer temperature averaged 224°F and ranged from 104 to 417°F. Seed cotton samples that were used to calibrate and validate the model had a satisfactory range of moisture. Seed cotton moisture averaged 10.5% and ranged from 7.1 to 16.9%. The measured mass flow rate of the cotton was highly variable (51% C.V.), but a calculated moving average improved the variability to 24% C.V. Data analyses that determine the performance of the model have not yet been completed. Ideally, the model works best with high (but safe) dryer temperatures, and good measurements of temperature, and air and seed cotton mass flow rate. Having a precise measurement of seed cotton moisture content will help ginners determine how much heat to use to dry their cotton.
