Due to the unique heating characteristics of microwave drying equipment, more and more attention has been paid to the processing of agricultural products and other fields. Microwave drying has the advantages of fast and uniform heating, good selectivity (faster heating in areas with higher moisture content), sensitive reaction, easy control and high energy utilization (mainly absorbed by the dried matter).
Lupinska et al. studied the microwave drying of rapeseed. It was found that microwave drying could sterilize rapeseed and produce less damaged seeds than hot air drying.
The feasibility of microwave drying rapeseed was studied, and the effects of microwave drying on seed value and quality characteristics were analyzed. It was concluded that microwave drying technology was feasible for rapeseed, which could not only dry rapeseed quickly and economically, but also maintain its seed value and improve edible quality, and had favorable variations, but could still be maintained later. Compared with hot air drying and far-infrared drying, microwave drying has the highest precipitation rate in constant-speed drying period, and microwave drying can enhance seed germination potential and improve the nutritional value of rapeseed.
