Moisture is a dynamic component of cotton and affects the quality of the lint during the harvesting, storage, and processing phases. This report describes the thin layer drying rates for acid delinted cotton seed at temperatures ranging from 68 F to 266 F. Absorption values are shown for temperatures of 68 F and 95 F. The drying data were plotted against time and found to be exponential. Nonlinear regression analysis was used to fit the value of the coefficients in the theoretical falling rate equation to the experimental data. The drying data produced a good fit to the theoretical falling rate (exponential decay) function at temperatures above 200 F. Temperature significantly affected the coefficient containing the diffusivity parameter in the drying equations. A generalized solution using absolute temperatures was developed which should be suitable for engineering calculations.
