ABSTRACT
Majority of small scale farmers and homes are still using open-sun and/or non-convective methods for
drying due to either high cost of gas/electric dryer or lack of electricity in their locations. These
methods are time consuming and exposed the products to rain and contamination. A maintenancefriendly
and properly enclosed dryer is therefore desired. The batch kerosene heated dryer was studied
and adapted to suit the need of these people. In this work, the heat and mass transfer analysis of potato
drying in a batch kerosene heated oven is considered. The analysis concentrates on the drying
chamber of the system. First, the reasons for and working operations of the dryer were considered.
The temperature of the drying chamber was maintained constant (130oC) and sample thickness was
varied in two levels (0.005m and 0.01m). Fick’s diffusion model (among others) was modified and
used as a major equation to predict the effective moisture diffusivity (Deff) of the sample during the
drying period. The model was developed to describe the heat and mass transfer of the material in the
dryer; based on some assumed conditions. The experimental drying curves showed only a falling
drying rate period. The analysis and validation proves that the model could be used to predict the
particle moisture content and temperature profile, the average temperature of particles, the heating
rate, the activation energy (Ea) etc during the drying process. Comparing the predictions of the
conventional Fick’s model proposed in this study with the experimental data shows that the
temperature variation of sample during the drying has a strong influence on the prediction of the
drying model.
