A R T I C L E I N F O A B S T R A C T Article history: Received: 17 July, 2020 Accepted: 03 November, 2020 Online: 14 December, 2020 This research presents the outcomes of thin layer convective drying of ginger rhizomes with different treatments using the ARS-0680 environmental chambers for the drying process. TD 1002A – Linear Heat Conduction Experimental equipment was used in measuring the thermal conductivity of the ginger samples at varied temperature levels ranging from 10C – 60C and drying time of 2 – 24 hours. The result of this experiment shows that the average moisture content for 2 hours drying at 60C was 70.6% while at 24 hours drying was an average of 7.55% which is close to the range of 4 – 7%. The drying rate at drying times of 24 hours was 0.889/C and 0.4437/C for 2 hours drying, giving 50% by moisture reduction rate. While the lowest moisture content (5.98%) is obtained for unpeeled ginger and the highest (9.04%) at 24 hours drying at 60C, the analysis shows the variation in the temperature varied as the ginger shrinks when subjected to heat.
