Abstract

The present invention discloses a dry heat sterilization system, which comprises a spray drying tower, wherein the center on the tower top is provided with a hot wind distributor, the hot wind distributor is connected with the pipeline of a hot wine mechanism, the hot wind mechanism comprises an air blower, a steam heat exchanger and an electrical heater, the gas outlet end of the air blower and the steam heat exchanger are connected, the gas inlet end of the steam heat exchanger is further communicated with steam so as to heat air, the gas outlet end of the steam heat exchanger is connected with the electrical heater, and the electric heater and the hot wind distributor are connected. According to the present invention, the hot air is subjected to the heating treatment again through the electrical heater, such that the temperature of the hot air is high so as to completely sterilize and solve incomplete sterilization problem caused by the wet sterilization.

Description

technical field [0001] The invention relates to a dry heat sterilization system, in particular to a dry heat sterilization system used in spray drying equipment. Background technique [0002] The aseptic spray drying device is the main equipment for the production of powder injections in the pharmaceutical industry, including antibiotics such as streptomycin sulfate, gentamicin sulfate, kanamycin sulfate, etc. In the production process of these products, sterile spray drying equipment is required to prepare finished products. [0003] There are many aseptic links involved in the existing spray drying tower, including the sterilization of the feed liquid, the sterilization of the dry air, the sterilization of the cooling air, the sterilization of the equipment of the spray drying tower, etc. Among them, the sterilization of the equipment of the spray drying tower is undoubtedly It is difficult to work. The existing spray drying equipment for sterile injections is sterilized...
