Beschreibung
Zusammenfassung:	The utility model relates to the technical field of freeze dryers, and discloses a freeze dryer. The freeze dryer comprises: a housing; the cold trap is arranged in the shell; the evaporator is arranged in the cold trap; the refrigerating unit comprises a compressor, the compressor communicates with the evaporator, the compressor is arranged in the shell, the cold trap and the compressor are arranged in a staggered mode in the vertical direction, and the lower surface of the cold trap is lower than the upper surface of the compressor so that the height of the freeze dryer can be reduced. The lower surface of the cold trap is lower than the upper surface of the compressor, that is, the compressor is arranged on one side of the cold trap, and the height difference between the upper surface of the cold trap and the lower surface of the compressor is smaller than the height difference between the upper surface of the cold trap and the lower surface of the compressor when the compressor is arranged below the cold
