Abstract
This study developed a multilayered moisture conservation model (MCM) to reflect the structural differences of soybean. The blue-channel image derived from image analysis revealed two different structure regimes in the soybeans. Computational fluid dynamics simulations were used to simulate the flow fields of the convective dryer and estimate the mass transfer coefficient from the local air velocity (2.04 m/s). The MCM accurately predicted the moisture changes of soybean during continuous and intermittent drying (RMSE <0.214). During an effective drying time of 600 min, increasing the intermittency from 0 to 0.5 decreased the moisture content from 8.04 to 6.57%.
