High-density carbonic anhydride disinfection device and method for germicidal treatment

Abstract

The invention discloses a high-density carbon dioxide sterilizing device, which includes a high-density carbon dioxide producing and delivering unit, which is connected with a reaction kettle and is used for delivering the produced high-density carbon dioxide to the reaction kettle after being preheated by a preheater, and sterilizing the sample in the reaction kettle; a sterile isolating unit, which is a hollow sterile enclosed space, and in which the reaction kettle is placed in the sterile isolating unit; a heat preserving unit, which is respectively connected with the preheater and the reaction kettle, and is used for controlling the temperature in the preheater and the reaction kettle; a digital automatic control unit, which is respectively connected with the high-density carbon dioxide producing and delivering unit and the reaction kettle and is used for sitting, controlling, recording and processing the temperature and the pressure parameter in the high-density carbon dioxide producing and delivering unit, and the temperature and the pressure parameter in the reaction kettle. The high-density carbon dioxide sterilizing device has the advantages that the reaction kettle is arranged in the sterile isolating unit, second pollution is avoided, cleaning is facilitated, space and cost are saved, and the process effect is improved.

Description

technical field [0001] The invention relates to a high-density carbon dioxide sterilizing device for preventing secondary pollution, in particular to a high-density carbon dioxide sterilizing device for food, medicine, cosmetics or enzyme sterilization and a method for sterilizing the same. Background technique [0002] As an emerging non-thermal sterilization technology, high-density carbon dioxide (Dense phase carbon dioxide, DPCD) sterilization technology has attracted the attention of researchers at home and abroad due to its good sterilization effect. [0003] During the research process in recent decades, the high-density carbon dioxide sterilization devices developed at home and abroad mainly include intermittent, semi-continuous and continuous types. However, looking at the existing intermittent high-density carbon dioxide sterilizing devices at home and abroad, there are currently the following problems: the reaction kettle is placed in the external environment, whi...

AI Technical Summary

Problems solved by technology

However, looking at the existing intermittent high-density carbon dioxide sterilizing devices at home and abroad, there are currently the following problems: the reactor is placed in the external environment, which is likely to cause secondary pollution; the structure is complex, cannot be disassembled immediately, cleaning is inconvenient, and there are dead ends in hygiene , so the overall device and design need to be further improved
