Effect of irradiating power and temperature of sending air in the microwave cocoon drying

Abstract

  The effect of irradiating power and temperature of sending air in the microwave cocoon drying was investigated. The product of drying term and irradiating power was roughly at a certain numerical value in the same temperature of sending air. Therefore, the necessary time of cocoon drying coud be presumed by the irradiating power. The sending air at 60°C coused the drying speed to fall on about 60% or 70% at 100°C, and had a strong influence at the low irradiating power.
