This paper is concerned with drying kinetics and models of heat pump drying (HPD) of green soybean. Experiments were done for continuous and intermittent drying with intermittency of 1, 3 and 6. Drying rate decreases sharply in continuous HPD process, while circuitously in intermittent HPD process. Peak drying rate values appear in every drying period of intermittent drying and differ a lot because of different intermittent ratios. In addition, various mathematical models were investigated to describe the HPD kinetics of green soybean seeds. Fitting suitability of the experimental data by models was specified as comparing the coefficient of correlation (R-2), mean absolute percentage error (EMD%), Chi-square X-2 and root mean square error (ERMS). The page model and 23rd model were found to be the most suitable models in describing the continuous and intermittent drying of green soybeans, respectively.
