Influence of Temperature, Air Velocity, and Ultrasound Application on Drying Kinetics of Grape Seeds
The objective of this work was to determine the influence of
temperature, air velocity, and ultrasound application on the drying
kinetics of grape seeds. The drying kinetics were determined at
1.0, 1.5, 2.0, and 3.0 m/s and at 40, 50, 60, and 70 C. At 1.0
and 1.5 m/s, the experiments were carried out with and without
ultrasound application. To establish the influence of the variables
on the drying kinetics, the results were modeled by means of both
the Peleg and a diffusion model. The activation energy was determined
(Arrhenius equation). For an air velocity of over 1.5 m/s,
it was determined that the external resistance to mass transfer
was negligible. No influence of ultrasound application was observed,
probably due to the fact that grape seeds are very hard and have
a low level of porosity.The authors of this article acknowledge financial support from the Valencian Government ("Generalitat Valenciana,'' Valencia, Spain, PROMETEO/2010/062).Clemente Polo, G.; Sanjuán Pellicer, MN.; Cárcel Carrión, JA.; Mulet Pons, A.
