Convective Drying of Ginger Rhizomes

Convective Drying of Ginger Rhizomes

Abstract

This paper presents the results of convective drying of ginger rhizomes under blanched, unblanched, peeled and unpeeled conditions using the ars-0680 environmental chambers for the drying process and td1002a—linear heat conduction experimental equipment to measure the thermal conductivities of the ginger at six temperature levels ranging from 10 to 60 °C and drying times of 2 and 24 h. The drying curves were drawn using the moisture and conductivity data. The drying rate at higher drying times (24 h) was 0.889/°C and 0.4437/°C for 2 h-drying, giving 50% in moisture reduction rate. Whereas the initial moisture content was 95.12%, it reduced to 59.33% for the 24 h-drying time. The result of this study shows that the lowest moisture content (5.98%) was obtained for unpeeled ginger while the highest was the blanched (9.04%) all for 24 h-drying and at 60 °C. The average moisture content for 2 h drying at 60 °C was 70.6% while for 24 h drying; it was an average of 7.55%. Which is close to the target of 4–7% desired for this research. Though our results made our target, they are in line with the literature results that recommend moisture content of 7–12%. These show the superiority of higher temperature drying and the use of the convective drying method. The thermal conductivity for 24 h-dried ginger at 60 °C approximates to the thermal conductivity of dried ginger and it is 0.050 W/mK on the average. The unpeeled ginger gave the lowest value of 0.046 W/mK while the unblanched ginger gave the highest value of 0.055 W/mK. For 2 h of drying, the average value was 0.079 W/mK while the unblancehd ginger gave the lowest (0.076 W/mK) while the blanched the highest (0.084 W/mK).
