Description

Technical Field

[0001] The utility model relates to the technical field of pure ethanol gas sterilizers, in particular to a pure ethanol gas sterilizer. Background Art

[0002] "Sterilization" is an important means to ensure that the microbial index of pharmaceutical and health care solid preparations meets the standard. In the process of manufacturing solid preparations, pharmaceutical factories must perform "hot pressure sterilization" (121℃ / 30min) on the materials to ensure that the microbial index of the finished products meets the standard. The sterilization effect is reliable, so it is widely used.

[0003] Hot pressure sterilization, also known as moist heat sterilization or moist heat steam sterilization, is a sterilization method that uses steam provided by a boiler for sterilization. In actual applications, it is found that "hot pressure sterilization" has the following defects:

[0004] 1. Solid materials tend to clump after sterilization, so the materials need to be dried and crushed again. This not only adds two processes, but also increases the risk of re-contamination;

[0005] 2. The "temperature of hot pressing sterilization is too high" (121℃), which also causes great damage to some effective ingredients in traditional Chinese medicine. For example, the content of gardenia glycoside contained in Huangzhizi is lost by nearly 30% after hot pressing sterilization.

[0006] Studies have shown that ethanol can effectively kill microorganisms in traditional Chinese medicine by penetrating microbial cells and their spore walls to denature proteins. Utility Model Content

The tank body is also provided with a cleaning pipe, which is located in the axial tube close to the hot water pipe and is connected to the two automatic cleaning nozzles.

[0012] As an improvement, the top cover is provided with a cover-tightening handle, and a hanging ear is provided on one side of the top cover, and the hanging ear is fixedly connected to the tank body.
