The application discloses a vacuum drying cabinet and a vacuum drying cabinet drying method, which comprises a vacuum cabin body, a vacuum pumping device connected with the vacuum cabin body and used for pumping the inside of the vacuum cabin body, and a hot air circulating device connected with the vacuum cabin body and used for supplementing heated air into the vacuum cabin body. The hot air circulating device is arranged to supplement heated air into the vacuum cabin body, so that the inside of the vacuum cabin body and the surface of instruments needing to be dried in the vacuum cabin body can be rapidly heated, the problem that the temperature of the surface of the instruments in the vacuum cabin body is reduced when the moisture on the surface of the instruments is vaporized can be effectively solved, the moisture vaporization speed after each vacuum pumping in the circulating drying process is improved, and the drying efficiency is improved. Moreover, the hot air circulating device is used for supplementing heated air into the vacuum cabin body, the heated air is supplemented into the vacuum cabin body when the pressure of the vacuum cabin body is released, the problem that the dried instruments are secondarily dampened or condensed due to the low temperature of the supplemented air is avoided, and the drying efficiency is further improved.
