Description

Sterile conveying device for freeze-drying tray and tray feeding and discharging system Technical Field The invention relates to the field of pharmacy, in particular to a freeze-drying tray sterile conveying device and a tray inlet and outlet system. Background In the pharmaceutical industry, the long-term preservation of the bulk drug is of great importance, and the freeze-drying technology is widely applied to the field of bulk drug processing because the original activity of the drug can be maintained and the breeding of microorganisms is avoided. In the vacuum freeze-drying production flow of the bulk drug, the prepared bulk drug liquid is required to be filled into a freeze-drying disc, then the freeze-drying disc is conveyed to a plate layer in the box body of the freeze-drying machine for freeze-drying treatment, and the freeze-drying disc is required to be taken out from the box body of the freeze-drying machine after freeze-drying is finished so as to finish material receiving operation, so that a disc inlet and outlet link of the freeze-drying disc is a key step in the freeze-drying production process of the bulk drug, and the quality and the production efficiency of the drug are directly influenced by the operation standardization. Along with the continuous improvement of the requirements for aseptic production in the pharmaceutical industry, the aseptic control of the freeze-drying tray inlet and outlet links becomes the focus of industry attention, and the optimization and upgrading of related equipment have important significance for guaranteeing the sterility of drug production, reducing the production cost and improving the production convenience, and the demands for the freeze-drying tray inlet and outlet equipment with reasonable structure, reliable aseptic performance and convenient operation and maintenance in the industry are increasingly urgent. In current drug substance freeze-drying production practices, there are a variety of lyophilization tray access methods. One is a manual operation mode, an operator uses hooks to manually push freeze-drying trays to a plate layer in a freeze dryer one by one through gloves, after freeze-drying of materials is completed, the freeze-drying trays are pulled out through the hooks, the other is an automatic tray pushing mechanism mode, a tray pushing mechanism with freely telescopic push rods is respectively arranged in front of and behind a freeze-drying box, when the tray is fed, the freeze-drying trays are pushed to a box plate layer through push rods in the front of the program-controlled freeze-drying box, and when the tray is discharged, the freeze-drying trays are pushed out of the box body from the plate layer through push rods in the rear of the program-controlled freeze-drying box. The existing freeze-drying plate feeding and discharging mode has the problem of influencing the aseptic production of medicines, metal particles can be generated by direct friction between the bottom of the freeze-drying plate and the plate layer during manual operation, the metal particles possibly enter the medicines to influence the aseptic property of the medicines, and the automatic plate pushing mechanism is provided with more sealing structures and transmission mechanisms, so that the cleaning difficulty is high, the aseptic production risk is increased, the overall cost of the system is high, and the operation and maintenance difficulty is high.
