Description

Technical Field

[0001] The utility model relates to the technical field of drug freeze drying, in particular to a freeze drying machine for preparing drugs. Background Art

[0002] Vacuum freeze drying machine is also called freeze dryer. Vacuum freeze drying is to freeze the material below the eutectic point temperature first, so that the water in the material becomes solid ice, and then under the appropriate vacuum degree, the ice is directly sublimated into water vapor. Then the water vapor is condensed by the water trap in the vacuum system to obtain the technology of dry products. It is mainly composed of freeze drying box, cold trap (cold trap box), heating system, vacuum system, refrigeration system, control system;

[0003] The Chinese patent authorization announcement number: CN216204713U provides a freeze-drying device for preparing medicines. The solution can fix a placement box containing medicines to the support frame during use through the coordinated arrangement of a driving motor, a first shaft rod and a support frame, and then the support frame is rotated by the rotation of the driving motor, thereby playing a role in cooling the medicines evenly, achieving the purpose of improving the quality of freeze-dried medicines. Through the coordinated arrangement of a servo motor, a transmission belt, a cam and a second spring, the second shaft rod can be driven to rotate by the rotation of the driving motor during use, and then the cam is rotated, and the second spring is cooperated to make the filter screen vibrate up and down, thereby playing a role in preventing the filter screen from being blocked, and achieving the purpose of improving work efficiency.

[0004] However, the existing drying equipment has a relatively simple structural design. When the drying box body is connected to the drug placement tray, most of the time the drug placement tray is directly placed on the support frame inside the drying box body. This structural design makes it impossible for the drying box body to limit the drug placement tray, resulting in poor stability of the connection between the drying box body and the drug placement tray. The support frame cannot be disassembled. If the support frame is damaged, the entire device is in a semi-scrap state. Utility Model Content
