Influence of air flow velocity and temperature on drying parameters: An experimental analysis with drying correlations

Abstract

Experiments were conducted to analyse the effect of air flow velocity and air drying temperature on convective drying of moist object. The air drying temperatures are selected from 40 to 70°C and it is analysed with the range of air flow velocities from 2 to 6 m/s. Fresh potato is selected for sample moist object. Drying curve is drawn and drying correlations are presented for various air drying temperatures and velocities. Diffusion coefficient, density and shrinkage of the object are calculated from observed experimental measurements and these parameters are analysed with the impact of air flow velocities and temperatures.
