Description

High-pressure mixed gas sterilizer with low concentration of ethylene oxide Technical Field The utility model relates to the technical field of low-temperature high-pressure sterilizers, in particular to an ethylene oxide low-concentration high-pressure mixed gas sterilizer. Background The low concentration high pressure mixed gas sterilizer of ethylene oxide is a special sterilizing equipment designed for heat sensitive Chinese medicine product, and combines low concentration Ethylene Oxide (EO), low temperature environment and high pressure condition to balance sterilizing effect and safety. The sterilizer of the prior art has the following disadvantages: 1. The design pressure of the common ethylene oxide is 80KPa, when 10 percent EO+90 percent CO2 mixed gas is introduced, the pressure of the mixed gas is 1.5-2 kg, and the original ethylene oxide main body cannot bear the pressure after mixing; 2. the current higher concentration of sterilization medium (ethylene oxide) requires longer resolution time; 3. when part of traditional Chinese medicine sterilization is performed at high temperature by steam, serious hardening and content and morphology change of medicinal powder occur; 4.
