The Effect of Aeration Rate on Cooling of Cottonseed in The Mid-South

M. H. Willcutt and Suminto D. To


 
ABSTRACT

Cooling rates of cottonseed were studied utilizing instrumented chambers at five different aeration rates (0, 2.5, 5, 7.5 & 10cfm/ton). Seed, ambient and exhaust air temperatures, and exhaust relative humidity were measured and recorded during the study. Environmental conditions during the 1996 ginning season at Winona, MS did not result in an increase or decrease in the moisture content of seed when continuous aeration was performed. Temperature increases were observed at the upper levels of the chambers during the time when warmer weather conditions were moving through the area. Cooling front progression rates from about 2 ft/day for 2.5 cfm/ton to 5.4 ft/day for 10 cfm/ton were observed. A manager of a seed storage facility would be able to pass a cooling front through a 24 ft depth of seed in 12.5 days using the 2.5 cfm/ton aeration rate or 4.6 days using the 10 cfm/ton aeration rate. The difference between initial and final seed temperatures resulting from aeration was determined by the temperature of the ambient air and not by the aeration rate.
