| Summary: | The effect of high moisture content on drying characteristics of high moisture municipal solid waste (MSW) material, such as carrot peel and pomelo peel was investigated. The experimental data used to fit the selected published mathematical drying models of samples， were conducted in a thermogravimetric furnace. Weight reduction during drying was measured with a microbalance in the range of 80-140℃. The variations of moisture content and drying rate at different temperature were considered. The results show that with increasing in drying temperature the drying time decreased and the maximum drying rate increased at the beginning of drying process .The effective diffusivity ranged from 1.49×10-9 to 1.25×10-8m2/s with Fick's diffusion equation. The activation energy value of 17.12kJ/mol and 37.48kJ/mol was determined through Arrhenius equation. The Modified Page model and Weibull distribution model were the most adequate models in describing the drying process of MSW samples. DOI : http://dx.doi.org/10.11591/telkomnika.v12i3.4478 |
