Technologies (e.g., devices, systems and methods) for sanitizing reservoirs are described. In some embodiments, the technologies include a sanitization gas system and a connector unit. The connector unit is configured to install into a portion (e.g., wall, bottom, top, or lid) of a reservoir, such as a reservoir of a hot beverage maker. The connector unit includes an inlet passageway for supplying sanitizing gas (e.g., ozone) into the reservoir, and an outlet passageway for removing sanitizing gas from the reservoir. In some embodiments at least a portion of the outlet passageway is disposed radially around the inlet passageway. The sanitization gas system may provide a sanitizing gas to the inlet passageway and receive the sanitizing gas from the outlet passageway.

A fan coil apparatus includes an air flow path, a humidification unit, and a treatment applicator. The air flow path extends from a heating zone to a fan coil air outlet, and includes a humidification section. The humidification unit includes a humidification unit water droplet outlet and an air permeable water retaining member. The air permeable water retaining member and the humidification unit water droplet outlet are provided in the humidification section and the air permeable water retaining member is positioned downstream from the humidification unit water droplet outlet. The treatment applicator provides a disinfecting agent upstream from an air outlet of the humidification section.

A plasma generating apparatus according to embodiments of the inventive concept, which provides plasma to a biological material, includes a housing configured to provide an inner space in which plasma is generated, a ground electrode coupled to one side of the housing, a power electrode coupled to the other side of the housing, and a controller configured to control a generation mode of the plasma. The generation mode includes a first mode in which the plasma is provided to the biological material while generating the plasma and a second mode in which the plasma is generated in the housing, and then the generated plasma is provided to the biological material.

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.

The present invention relates to a method for decomposing peracetic acid and a method for culturing microorganisms using the decomposition method. The cultivation of microorganisms using the method of the present invention allows an effective removal of the peracetic acid used in a culture medium for sterilization.

Methods of manufacturing a light-activated powder are provided which provide solid-state generation and release of chlorine dioxide without detectable amounts of any toxic by-products such as chlorine gas, chlorites, or chlorates. The powder need not be exposed to moisture, relative humidity, or an acid before or during exposure of the powder to visible light to generate the gas. The powder can also be prepared under conditions that minimize or prevent decomposition or oxidation of sodium chlorite or premature light activation of the powder during the manufacturing process to maximize its activity.

The present invention has as its object the provision of an ozone generator that can generate ozone with high efficiency. The ozone generator of the present invention includes: source gas supply means for supplying a source gas containing oxygen; a gas flow channel forming member for forming a gas flow channel through which the source gas from the source gas supply means flows; and an ultraviolet light source for emitting ultraviolet light, the ultraviolet light source being disposed in the gas flow channel. The ozone generator irradiates the source gas flowing through the gas flow channel with the ultraviolet light from the ultraviolet light source to cause the oxygen in the source gas to absorb the ultraviolet light and thereby generate ozone. The ultraviolet light source comprises an excimer lamp for emitting ultraviolet light with a wavelength of not more than 200 nm. A flow rate of the source gas in a region where the ultraviolet light source is disposed in the gas flow channel is not lower than 0.1 m/s.

A continuous decontamination-and-sterilization device possessing high efficiency, reliability, and safety of operation to treat external surfaces of a package that is conveyed to a sterile working chamber. A decontamination chamber decontaminates (with a decontamination agent) bottom and lateral external surfaces of the package conveyed by a first conveyance, with an upper surface seal portion of the package being sealed. An aeration chamber removes residue of decontamination agent from an external surface of the package while the package is conveyed by a second conveyance means. A sterilization chamber sterilizes the upper surface seal portion of the package by irradiating electron beams as the package is conveyed by a third conveyance means, with the bottom or lateral external surface of the package being supported. The first conveyance means includes a sealing means by an adsorbing function to adsorb and capture the upper surface seal portion so as to seal the same and convey the package, with the bottom and lateral external surface portions of the package being open.
