Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical and chemical equipment, in particular to a freeze-drying tray breathing film cutting device. Background Art

[0002] In the production process of medicines or chemical products, freeze drying (lyophilization) technology is often used. Freeze drying is a process technology that freezes materials containing water or other solvents and then removes the ice or other solvents in the frozen materials directly from solid to gas without passing through the liquid state under vacuum conditions.

[0003] At present, sterile freeze drying trays are often used as containers for materials during freeze drying. The sterile freeze drying tray has a material port with a cover on the top, which is convenient for filling. The top of the tray is covered with a breathing membrane, which allows water and solvents to escape easily during sublimation drying. At the same time, the expanded polytetrafluoroethylene membrane also provides good barrier protection, effectively reducing the risk of cross-contamination of products, reducing the cleaning cost of the freeze dryer, and protecting the operators well.

[0004] After freeze drying, the operator needs to use a knife to cut the respiratory membrane of the freeze drying tray before unloading. In actual production, this cutting method often requires the operator to cut manually. However, manual cutting is prone to secondary cutting, resulting in flaking of the respiratory membrane, which in turn introduces foreign matter into the product, causing cross contamination and posing a risk to product quality.

[0005] A freeze-drying tray cutting tool can effectively prevent personnel from cutting again. At the same time, it is convenient to cut, avoids the shavings of the respiratory membrane, and avoids the quality risks caused by cross contamination.

[0006] Therefore, the art urgently needs a freeze-drying tray breathing membrane cutting device and a cutting method thereof, which can prevent operators from making secondary cuts to the breathing membrane, prevent foreign matter from contaminating the product, effectively avoid cross-contamination that affects product quality, and improve the efficiency and quality of freeze-dried product discharge.

The support assembly is used to support and fix the freeze-dried tray to be cut, and the cutting assembly is used to cut the respiratory membrane on the freeze-dried tray to be cut.

[0033] The base 1 includes a freeze-dried tray accommodating area 4 and a supporting frame 5. The supporting frame 5 is a rectangular frame. The freeze-dried tray accommodating area 4 is a cavity, and the cavity is used to place the freeze-dried tray of the respiratory membrane to be cut. A hinge 3 is fixedly installed on one side of the base 1, and one side of the flip frame 2 is connected to the hinge 3. The flip frame 2 is rotatably installed on the base 1 through the hinge 3, so that the flip frame 2 rotates relative to the base 1 with the rotating shaft of the hinge 3 as the rotating axis. The flip frame 2 plays a role in adjusting the positional relationship between the cutting component and the base 1. When cutting is required, the flip frame 2 drives the cutting component to flip to the top of the base 1. When cutting is not required, the flip frame 2 drives the cutting component to flip to the side away from the base 1, making room for the freeze-dried tray 9 to be cut to enter the freeze-dried tray accommodating area 4.
