This paper presents the analysis of the kinetics of sargassum drying using a direct solar dryer and the direct energy from the sun. Four mathematical models were applied: Newton, Page, Henderson and Pabis; and Midilli et al. The seaweed was brought from the coast of Cancun, Q. R, Mexico. With the direct solar dryer, a total of 6 hours were required to dry it, the final humidity ratio was 0.013. In the case of solar energy without dryer, i. e., in open air, 12 hours were required in two non-consecutive periods, and the final humidity ratio was 0.025. The solar radiation values, temperatures and mass variation were obtained as a function of time. The kinetic model that best simulated the drying process was that of Anderson and Pabis, obtained after the statistical analysis was performed, the activation energy was also obtained.
