The objective of this paper is an analysis of the influence of drying air temperature and the drying air velocity on the
particle density. The particle density of apple, banana, potato and carrot slices during convective drying was experimentally
determined. Drying experiments were conducted in a laboratory air-dryer, repeated at different air temperatures and air velocities.
The drying air temperatures considered were 40, 50, 60 and 70 °C with drying air velocities of 1, 2 and 3 m/s. Two simple
mathematical models for correlating the dimensionless particle density with the dimensionless material moisture content, drying air
temperature and drying air velocity are proposed. The models were fitted to experimental data and the correlation coefficients and
residual sum of squares were estimated.
