Document Type and Number:
WIPO Patent Application WO/2019/052544
Kind Code:
Disclosed is a condensation drying method for natural musk. The method involves: spreading out natural musk, wherein the thickness of the natural musk when spread out does not exceed five centimeters; placing same in a condensation drying oven; and drying the natural musk at a constant temperature of 5~50°C in a condensation manner until a drying weight loss rate is lower than 35%. By means of the condensation drying method, the precipitation of moisture by musk samples and the reduction of the relative humidity in a drying space are realized under hermetic and low-temperature conditions. The weight loss of the musk after condensation drying can reach pharmacopoeia standards, and the obvious loss of volatile components in the musk is not brought about. The method has a high drying efficiency, is easy to operate and has low costs.
