Tablet medicine microwave energy-saving drying method and device

The invention discloses a tablet medicine microwave energy-saving drying method and device, and relates to the technical field of microwave drying, the microwave drying process sequentially enters the stages of pre-drying, formal drying, waste heat drying and drying completion, and the method comprises the steps that according to the type of a to-be-dried tablet medicine, multiple parameters of microwave drying are preset; microwave drying is started with the lowest microwave frequency and the constant moisture removal power, and the real-time temperature and humidity in the drying box are obtained; in the pre-drying stage, according to comparison between real-time temperature and humidity and multiple preset parameters, the microwave frequency is gradually increased until the highest microwave frequency is reached; in the formal drying stage, the highest microwave frequency is kept for drying; in the waste heat drying stage, according to comparison of real-time temperature and humidity and a plurality of pre
