Abstract
The present invention relates to a non-contact microplasma ozonized mist radical sterilizer. The present invention minimizes two discharge spaces to a micro size to lower a breakdown voltage, concentrates electromagnetic fields using micro-patterns to induce micro-discharge at a normal pressure, and generates plasma through glow discharge, to increase electron density and reduce power consumption according to generation of microplasma. When oxygen and air are injected as reaction gases using this principle, ozone is generated as active species, and the generated ozone is used for various purposes such as removing pests, reducing ethylene, and sterilizing harmful bacteria. Sterilization is improved by sterilizing air and generating mist using ozone generated from microplasma, and then decomposition and drying of ozone gas are performed using a heat generation device and a catalytic method.
