A NEW APPROACH FOR MODELING OF HOT AIR-MICROWAVE THIN LAYER DRYING OF SOYBEAN
Journal Title: ELECTRONIC JOURNAL OF POLISH AGRICULTURAL UNIVERSITIES - Year 2012, Vol 15, Issue 3
Abstract
The drying characteristics of soybean during combined hot air-microwave drying were examined. The experiments were carried out for combination of five microwave power densities (0.89, 1.6, 3.2, 4.3, 5.3 W/g) and four levels of air temperatures (30, 40, 50 and 60 °C). Among several models which were fitted to the experimental data, the Modified Two Term model was introduced to be the most appropriate model to predict moisture ratio as a function of air temperature and microwave power density. The effective moisture diffusivity was calculated in the range from 8.740×10-10 m2/s to 3.9664×10-9 m2/s.
