AB  - This research discusses the effective moisture diffusivity on paddy drying with air dehumidified by
zeolite. The paddy with an initial moisture content of 22% (wet basis) was dried in fluidized bed dryer at
different temperature ranging 40-60°C. As a response, the moisture content in paddy was observed
every 10 min for operational drying time 90 min. In doing so, a mathematical model was developed to predict
the effective moisture diffusivity that was validated with average moisture content from the experiment. Result
showed that the effective moisture diffusivity of paddy dried with zeolite was higher than that of without
zeolite. The model also can fit with the experiment and be able to describe the moisture distribution accurately.
Moreover, the quality of paddy based on proximate analysis during the drying process was acceptable and
comparable with the quality of paddy dried without zeolite.
