Studies on drying kinetics of ginger slices

Abstract

In the present research work attempt were made to evaluate the drying rate of ginger slices by drying it in cabinet dryer. Different sizes of ginger were taken i.e. 5, 10 and 15 mm for drying. After every 20 min weight loss was recorded. The experiments were carried out for four different temperatures of 50, 60, 70°C by keeping the air velocity fixed at 1.3 m/s. It could be observed from the experiment that the moisture content of sliced ginger is decreasing with increase in drying time under all the treatments. Among the three sizes of ginger slice (i.e. 5, 10 & 15 mm) the removal of moisture is more in case of 5 mm slice followed by 10 mm and 15 mm. The higher moisture removal in case of 5 mm thick slices. Among the three drying temperatures, the loss of moisture reported to be higher in case of T3 followed by T2 and T1
