冷冻干燥是生产干蘑菇质量最好的方法，但需要较长的干燥时间和较高的成本。空气干燥（AD）的产品质量相对较差。为了实现快速干燥和高质量的产品，开发了微波冷冻干燥（MFD）和常压冷冻干燥（AFD）干燥蘑菇。通过对三种升华干燥工艺的比较，得出FD工艺的产品质量最好，但能耗最高。AFD蘑菇品质最差，干燥时间最长，但能耗最低。与FD和AFD相比，MFD的干燥质量和干燥效率相对较好。因此，MFD可以取代传统的FD， AFD也因其能耗低而值得推广。
Freeze drying (FD) yields the best quality of dried mushrooms but needs long drying time and higher cost. Air drying (AD) gives relatively poor product quality. In order to achieve faster drying along with high product quality, microwave freeze drying (MFD) and atmospheric freeze drying (AFD) were developed to dry mushrooms. By comparison of three sublimation drying processes, it was concluded that FD could lead to the best product quality, but cost the highest energy consumption. AFD mushrooms had the worst quality and longest drying time, but the lowest energy consumption. Compared with FD and AFD, MFD could get relatively acceptable quality and drying efficiency. As a result, MFD can be used to replace traditional FD, and AFD also should be popularized because of its low energy consumption.
