Effect of microwave vacuum drying on drying kinetics and physical properties of germinated lentils
Authors: Nongmaithem, R., V. Meda, L. G. Tabil
Description: The aim of this study was to investigate the effect of microwave-vacuum drying of germinated lentils on drying kinetics and effective moisture diffusivity. Also to investigate the physical changes viz, texture and bulk density, particle density and porosity of the germinated dried lentils at different moisture content. The germinated lentils were dried using microwave-vacuum technique, using 20%, 50% and 80% of 2000W microwave power at 1.75 kPa vacuum pressure. Modified page model II showed highest R2 and lowest RMSE values. The drying rate constant and effective moisture diffusivity increases with increase in microwave power level. There were significant difference in physical properties between the germinated dried lentils and raw seeds. Bulk density, particle density and breaking force decreases with increase in moisture content while porosity increases with moisture content for germinated dried lentils.
