Microwave power is seen as a promising alternative to conventional methods for drying freshly harvested grains to safe storage moisture levels. In an attempt to elaborate a continuous flow microwave dryer, the optimum operating characteristics of a prototype microwave antenna were investigated during a low power microwave drying simulation with corn at three different moisture content levels (15%, 23% and 30% w.b.). The antenna consisted of a slotted waveguide with the orientation and width of the slots being the main points of investigation. / The optimum angle of the slots with respect to the direction of propagation of the travelling wave was found to be in the neighbourhood of 55° at all moisture contents. Slots 13 mm wide gave better results than the 6 mm ones which are often suggested in literature.
