DRYING CHARACTERISTICS OF RANGOLA GRASS

To fit the desorption isotherm and adsorption isotherm for Pangola grass, the modified Henderson model, Chung-Pfost model, modified Halsey model, and modified Oswin model were used to fit the experimental EMC /ERH data. A step-by -step ERH measuring technique was used in this study. The ERH data were collected at three temperature levels of 5 $^{\circ}C$, $25^{\circ}C$ and 5$0^{\circ}C$ for Pangola grass whole plant, stem , and foliage. The modified Halsey model has the best fit for both desorption isotherm and adsorption isotherm of Pangola grass whole plant as compared with other models.
