Abstract Soybeans were rewetted to
selected levels of initial moisture content and then dried in a microwave field
under various conditions of microwave power and inlet air condition. An
empirical diffusion model, based on the assumption that the surface moisture
content is an exponentially decreasing function of the initial, free moisture
content, fit the data very well. This modelling technique resulted in good
fits to independent data on soybean drying. Tests showed that soybeans may be
dried in a microwave field much more rapidly than by convection alone, with
no reduction in germination
for absorbed power levels below 0.13 W/g. Key Words: Microwaves, Drying, Soybean,
Diffusion model. |
