Description

Technical Field

[0001] The utility model relates to the technical field of freeze dryers, in particular to a freeze dryer with hydrogen peroxide sterilization. Background Technique

[0002] A freeze dryer with hydrogen peroxide sterilization is a freeze drying device that uses vaporized hydrogen peroxide for disinfection and sterilization. This device precisely controls the generation and distribution of hydrogen peroxide gas through a control system, effectively killing microorganisms while avoiding the problems brought by traditional steam sterilization methods.

[0003] After retrieval, Chinese Patent Publication No. CN107356054A discloses a freeze dryer with hydrogen peroxide sterilization and a sterilization method, including a freeze dryer and a vaporized hydrogen peroxide sterilizer. The air outlet of the vaporized hydrogen peroxide sterilizer is connected to the freeze drying chamber of the freeze dryer through an intake pipe, and the condenser of the freeze dryer is connected to an exhaust fan through an exhaust pipe. Control valves are provided on both the intake pipe and the exhaust pipe. The freeze dryer with hydrogen peroxide sterilization of the present invention generates hydrogen peroxide gas (VHP) through the vaporized hydrogen peroxide sterilizer, and introduces the hydrogen peroxide gas into the freeze drying chamber and condenser of the freeze dryer to disinfect and sterilize the box body and pipeline of the freeze dryer. The gas after disinfection and sterilization is discharged through the exhaust pipe. The freeze dryer is thoroughly disinfected and sterilized, and the disinfection and sterilization cycle of the freeze dryer is shortened.

[0004] In the actual use process of the existing freeze dryer, since the support frame is a whole, when taking and placing the placement tray, after the placement tray on one layer collides with the support frame, the placement tray on the other side will shake, affecting the uniformity of sample distribution. Therefore, a freeze dryer with hydrogen peroxide sterilization is needed to stably fix each layer of placement tray in the required position, so that the temperature and vacuum degree act uniformly on each sample. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a freeze dryer with hydrogen peroxide sterilization to solve the problem that in the actual use process of the existing freeze dryer, since the support frame is a whole, when taking and placing the placement tray, after the placement tray on one layer collides with the support frame, the placement tray on the other side will shake, affecting the uniformity of sample distribution as mentioned in the above background technique.

[0018] First, in the present utility model, through the provided limit component, when the placement tray is placed on one layer of the support frame and a pushing force is applied to the connecting column, the connecting column moves inside the movable frame, so that the limit plate is pushed into the limit frame. Under the action of the rotating column, a turning force is applied to the connecting rod, so that one side of the connecting rod is clamped and fixed inside the connecting frame. This solution stably fixes each layer of the placement tray at the required position, enabling the temperature and vacuum degree to act uniformly on each sample.

[0019] II. Based on Advantageous Effect 1, when the placement tray needs to be placed inside the support frame with the coordinated use of the guiding components, first apply an upward pulling force to the fixed tube to remove the support column from inside the fixed rod.
