Thermodynamic properties of water desorption in Buchenavia capitata (Vahl) Eichler

Abstract: A B S T R A C TThermodynamic properties provide information on energy demand and kinetic parameters in water sorption processes in agricultural products. Such information is essential to analyze and scale drying and storage equipment. The objective of this study was to determine the thermodynamic properties involved in the water desorption process in Buchenavia capitata (Vahl) Eichler seeds with moisture contents ranging from 13.31 to 7.21% dry basis (d.b.), obtained by the indirect static method, at temperatu… Show more

“…Nevertheless, high grain drying temperatures accelerate the migration of water vapor to the external atmosphere (Botelho et al, 2018), which, despite initially suggesting lower energy costs, damages grain structure (Saath, et al, 2010). Moisture diffusivity in the grain is directly related to the energy required to transform free water into vapor, which are both inversely proportional; in other words, the greater the diffusivity, the less energy is needed (Silva et al, 2018;Teixeira et al, 2018).…”
