Kinetics of microwave drying of a free-flowing organic material

Study into effects of a microwave field on the plant tissue

“…Studying the drying at a microwave heating shows that it is possible to significantly reduce energy consumption [17]. Microwave heating under drying regimes demonstrates a considerable intensification of the process [18]. At an increase in the output power of a magnetron by 4 times, the duration of drying reduces by about 5 times.…”

“…However, the paper does not report an analysis of the impact of the type of material and the amount of loading on such required characteristics as treatment duration and power output of the magnetron. Research into microwave drying of fruits and plants is still under way [18,19], however, the drying of raw materials with a high moisture content is not feasible. This leads to loss of quality and high energy costs, since the primary substance that absorbs electromagnetic energy is water.…”
