Drying

Drying is a process accompanied by heat and mass exchange between the drying agent for example air or flue gases and the moisture of the material being dried The vapor pressure of the liquid on the surface of a solid material increases with temperature and the vapor diffuses into the flow of the drying

The Influence of Abrasive Pretreatment on Hot Air

The drying of grapes is a more complex process compared to the dehydration of other agricultural materials due to the necessity of a pretreatment operation prior to drying Grape drying to produce raisins is a very slow process due to the peculiar structure of grape peel that is covered by a waxy layer Its removal has been so far carried out by using several chemical pre-treatments
