ABSTRACT: The application of rapeseed flowers has attracted more and more attention. However, little research has been done on the drying of rapeseed flowers, especially the microwave drying of rapeseed flowers.
The effect of power of microwave drying equipment on drying speed and quality of rapeseed flower was studied. It was concluded that microwave drying speed, quality and color of rapeseed flower were faster than hot air drying. Because rapeseed petals are small, the power density of microwave drying is much higher than that of peony petals, and the upper limit of power density is 31.4 W/g.
