中藥方劑微波乾燥法之評估

Evaluations of Microwave Drying on Chinese Medical Preparations

摘要


微波是一種電磁波,一般應用於加熱、乾燥等。以2450 MHz的微波對三種中藥方劑浸膏進行乾燥。乾燥的速度受中藥方劑之組成、試樣的厚度、微波的功率與乾燥時間等因素的影響。試樣加熱後的溫度在82-89℃之間。試樣內部的水分的乾燥,微波乾燥法比傳統式加熱法快。

Microwaves are a form of electromagnetic radiation which are useful for heating and drying. In this report, different microwave drying methods were applied to three Chinese medical preparations. The drying rate of 2450 MHz microwave was affected by the natural properties of the sample, thickness of the sample, power of microwave, and duration of microwave drying. The temperature of samples, after drying by microwave, was found between 82-89℃, The internal moisture moves easier for microwave drying than the traditional drying method.
