A freeze-drying machine. The machine comprises a freeze-drying tank (7) and a bottle in/out component. A set of ascending/descending plate-surfaces is provided inside said tank (7), said set comprising multiple freeze-drying plate-surfaces (71) on which bottles (9) can be disposed. The bottle in/out component comprises a drive mechanism, a pull-push rod (3) driven by the drive mechanism to make reciprocating linear movement about two sides of the free-drying plate-surfaces (71), and a push-pull member (4) used for pushing in and pulling out bottles, the push-pull member (4) connecting to and detaching from said push-pull rod (3) by means of a clutch structure. The invention prevents bottle breakage, is simple in structure, low in cost, and is safe and reliable. |
