The invention discloses a condensing drying method of natural musk. The method comprises the following steps of: paving musk, wherein the paving thickness does not exceed 5cm; putting the musk in a condensing drying box; and condensing and drying the musk at a constant temperature of 5-50 DEG C till the drying weight loss ratio is lower than 35%. According to the characteristics that the musk is much in water and more in volatile medicinal composition, the demand of absorbing water in a musk sample and reducing the relative humidity in a drying space under a sealed low temperature condition ismet by adopting the condensing drying method creatively. The drying weight loss ratio of the condensed and dried musk can reach a pharmacopoeia criterion, and obvious loss of the volatile componentsin the musk is not caused. The method is relatively high in drying efficiency, simple to operate and low in cost, and has a good application prospect.
