Problems solved by technology

[0004] Compared with the traditional method, the latter method has greatly improved the maintenance of sterility, but there is still a lot of manual intervention in the process of loading the trays into the automatic tray loading and unloading device, and there is a high risk of tray contamination during this process. Risk, not conducive to ensuring sterility

Embodiment Construction

[0016] In order to make the present invention more comprehensible, a preferred embodiment is described below in detail with the accompanying drawings.

[0017] Combine figure 1 , The present invention provides a method for automatically transferring the freeze-drying tray of APIs to the layer of the freeze-drying machine, and the steps are:

[0018] Step 1. Put the tray 1 into the automatic dish washer 2 located in the clean room and clean it;

[0019] Step 2. Transfer the cleaned tray 1 to the tray sterilization tunnel oven 4 through the chain plate 3 for sterilization and drying;

[0020] Step 3. After the tray 1 is sterilized and dried, the automatic tray-in / out device 8 moves along the track 6 to the sterilization tunnel oven 4 for docking, and the tray 1 is protected by the A-level unidirectional submerged protection device 5 located above the docking area. take out;

[0021] Step 4. Combine figure 2 , The automatic disk access device 8 moves along the track 6 to the door of the ...

Abstract

The invention provides a method for automatically transferring a material drug freeze-drying tray to a freeze drier ply. The method is characterized by comprising the following steps: taking the tray out of a tray sterilizing tunnel oven by using an automatic tray feeding and discharging device; putting the tray into a freeze drier, putting while feeding until all the plies of the freeze drier are filled; and then starting the freeze drier to carry out freeze-drying. The method provided by the invention has the advantages of solving the high-risk problem of manually tray transferring or tray loading in the traditional method, guaranteeing that the whole tray transferring process is automatically completed under the asepsis protection state and conforming to the requirements of international pharmaceutical industry CGMP (current good manufacturing practice), and has high sterility.

Description

Technical field [0001] The invention relates to a method for automatically transferring a raw material drug freeze-dried tray to the layer of a freeze dryer, so that a series of aseptic operations of the raw material drug freeze-drying tray are automatically completed under the control of the aseptic process from the start of cleaning. Background technique [0002] The traditional process of transferring the lyophilized API tray to the layer of the lyophilizer is as follows: First, the operator removes the cleaned, sterilized and dried API lyophilized tray (hereinafter referred to as the tray) from the sterilizer, and then The tray is filled with the material liquid, and then the tray filled with the material liquid is manually transported to the layer of the freeze dryer, and finally the freeze-drying box door is closed to freeze-dry the API. [0003] The typical freeze-drying steps of sterile APIs are as follows: first, the cleaned, sterilized and dried trays are transported by ...
