The main objective of this research is the study drying kinetics and thermodynamic properties kelp using heat pump technology. effects independent variables temperature (20–50 °C), air velocity (0.3–1.3 m/s), humidity (20–50%), thickness (0.8–4.2 mm) on time, moisture uniformity, effective diffusivity (Deff), activation energy (Ea), enthalpy (ΔH), entropy (ΔS), Gibbs free (ΔG) were investigated...

Melon is considered a product of high commercial value, but its post-harvest shelf life short at room temperature. As an alternative to reducing postharvest losses, osmotic dehydration arouses interest as pre-treatment for fruit drying. The present work aimed obtain the drying curves in osmotically dehydrated melons, followed by conventional A syrup was prepared using crushed crystal sugar up c...
