Title : Impact of drying parameters and methods on the volume increase of dried apples during their rehydration
Key words : manner of grinding, temperature, velocity of drying air, drying, rehydration, volume, apple
Summary :

The objective of this paper was to analyse the impact of parameters and drying method on the increase of the volume of dried apple slices and cubes during their rehydration. Ligol apples (cut into 3 and 10 mm slices and 10 mm cubes) were dried with the following methods: natural convection (temperature of drying 60ºC), forced convection (a tunnel drier, parameters of drying air: 50, 60, 70ºC and 0,5, 2 m•s-1), fluid drying (60ºC and 6 m•s-1). Dried fruit were rehydrated in the distilled water of 20ºC temperature. Determination of volume was carried out with an uplift pressure method in petroleum ether. Tests proved the impact of ground dried particles and the impact of drying method on the increase of the volume of dried apples during their rehydration. The final volume of the rehydrated dried fruit increased along with the reduction of drying temperature, these differences in numerical values were low, but statistically significant.
