Semi-continuous energy-efficient dry heat sterilization cabinet having sterile butt joint with RABS (Restricted Access Barrier System)

Abstract

The invention discloses a semi-continuous energy-efficient dry heat sterilization cabinet having a sterile butt joint with an RABS. The cabinet is characterized in that: the cabinet comprises a sealed cabinet body and a vehicle track; one end of the sealed cabinet is provided with an vehicle entry door, and the other end of the sealed cabinet is provided with a vehicle exit door; an interval isolation door is transversely arranged in the sealed cabinet, a heat sterilizing chamber is arranged between the vehicle entry door and the interval isolation door, and a cooling chamber is arranged between the interval isolation door and the vehicle exit door; and the vehicle track which is arranged in the sealed cabinet body traverses the bottom of the interval isolation door, one end of the vehicle track reaches toward the bottom of the vehicle entry door, and the other end of the vehicle track reaches toward the bottom of the vehicle exit door. According to the present invention, the inner ofthe sealed cabinet body is divided into the heat sterilizing chamber and the cooling chamber, and the vehicle exit door of one side of the cooling chamber has a direct butt joint with the RABS, so the sterile butt joint between the sterilization cabinet and the RABS which is a usage point is satisfactorily solved, and risks brought by a case that inner packaging materials and appliances are artificially transferred to the RABS after being sterilized in sterile medicament production processes are avoided, thereby the cabinet allows sterile level and visible foreign matter level of products to be effectively controlled, energy to be saved, and efficiency to be high.

Description

technical field [0001] The invention relates to a sterilizer, in particular to a dry heat sterilizer used for sterilizing inner packaging materials and containers in the production process of aseptic drugs and for aseptic transfer to RABS (Restricted Access Barrier System). bacteria cabinet. Background technique [0002] During the production process of sterile drugs, dry heat sterilization is required for the inner packaging materials and containers. [0003] The heat sterilization and cooling of the existing traditional dry heat sterilization cabinets are carried out in the same chamber, and the sterilized inner packaging materials or containers can only be taken out for use after the sterilization cabinet cools down after sterilization. Dry heat sterilization cabinets require a relatively high sterilization temperature, generally at 250°C. In order to insulate the heat, the insulation board of the door is very thick, and the sterilized items can only be taken out manuall...

Problems solved by technology

However, these methods and measures do not fundamentally avoid risks, and the above measures and methods require large investment and energy consumption

At the same time, because the traditional dry heat sterilization cabinet needs to be heated from normal temperature to the sterilization temperature, after the sterilization is completed, it must be cooled to a certain temperature before the sterilized items can be taken out; The body is heated to the sterilization temperature, because the heat capacity of the sterilization cabinet itself is much larger than that of the sterilized items, so the energy consumption of each sterilization cycle is high and time-consuming
