Estudo da cinética de secagem, contração volumétrica e analise da difusão líquida do morango (Fragaria Sp.)

Abstract

The present work aimed to study the drying kinetics, analysis of shrinkage, as well as obtaining the values of liquid diffusion during the process of drying the fruits of strawberry. The fruits of the strawberry were dried at temperatures of 40, 55 and 70 °C. During the drying behavior of the fruit has been studied as the change in volume and loss of water from the start until the fruits have reached a moisture content of approximately 0.25db. Experimental data to mathematical models able to describe the drying process and reducing the volume were applied. The models Midilli and Bala were most adapted to describe the kinetics of drying and shrinkage, respectively. The liquid diffusion increases with increasing temperature with values between 1.14 x 10 and 5.64 x 10 m s
