The invention relates to the technical field of vacuum freeze drying, and discloses vacuum freeze drying equipment which comprises a freeze vacuum drying cavity, a normal-temperature vacuum crushing cavity is formed in one side of the freeze vacuum drying cavity, a groove is formed in the bottom of an inner cavity of the freeze vacuum drying cavity, and the groove extends into the normal-temperature vacuum crushing cavity. And a placement plate is arranged in the freeze vacuum drying cavity, a quick mounting assembly used for mounting penicillin bottles is arranged above the placement plate, and the bottom of the placement plate is in sliding connection with the groove. The invention also discloses a stable freeze-dried composition with anti-wrinkle and repairing effects and a preparation method thereof. Due to the fact that the placement plate is frozen in the freezing vacuum drying cavity, the placement plate is in a low-temperature state and is not prone to contact at the moment, the placement plate needs
