An ozone treatment device includes an ozone destruct module and an ozone generator mounted within a housing. The ozone destruct module and the ozone generator are mounted between corresponding air inlets and air outlets formed in the housing. The ozone treatment device also includes a controller mounted to the housing. The controller is configured to generate ozone with the ozone generator for a first time period and to automatically destruct ozone with the ozone destruct module for a second time period following the first time period. In certain implementations the treatment device includes an input device for receiving an operator input. In such cases the controller can determine the first and second time periods based on the operator input.

An active oxygen supply apparatus includes a casing, a plurality of plasma generating devices provided in an inside of the casing and configured to generate an induced flow containing ozone, an ultraviolet light source provided in the inside of the casing and configured to irradiate the induced flow containing the ozone with ultraviolet light, and a shielding plate provided in the inside of the casing and configured to shield the ultraviolet light irradiated to an outside of the casing through an opening portion of the casing. An active oxygen generated by irradiating the induced flow containing the ozone with the ultraviolet light from the ultraviolet light source supplies to the outside of the casing through the opening portion of the casing.

A method and apparatus for reducing pathogens in successive pre-measured units of a flowable food product without substantially increasing the head height requirement of a feed production system. A plurality of containers are moved about a path within a housing. The path has a plurality of stations, such as a receiving station, one or more sanitizing stations, and a dispensing station, and a container cleaning station. A pre-measured unit of the flowable food product is received at the receiving station into a container. The pre-measured unit of the flowable food product is exposed to one or more sanitizing agents at one or more sanitizing stations. The pre-measured unit of the flowable food product is dispensed into the packaging device at the dispensing station. The containers are then cleaned at the container cleaning station to prepare each container to receive a subsequent pre-quantified unit of the flowable feed product.

Only a bottle properly preliminarily heated is sterilized by hydrogen peroxide. Temperature inspection to the bottle is performed while travelling the bottle. During the inspection, a bottle of which temperature does not reach a predetermined temperature is removed and a bottle of which temperature reaches the predetermined temperature is continuously travelled, hydrogen peroxide condensed mist α is blown toward a mouth portion 1a of the bottle by a spray tube 59 disposed at a predetermined position, and hot air is blown into the bottle from the nozzle while the nozzle 64 following the mouth portion of the bottle. According to such operation, only the bottle properly heated can be sterilized by the hydrogen peroxide, Thereafter, beverage fills the bottle, which is then sealed.

Disclosed is a process for treating at least one hollow body made of thermoplastic material, such as a preform or a cap, the treatment process successively including at least the following steps: a first step, consisting in treating at least the inside of the hollow body using hydrogen peroxide; a second step, consisting in heating the hollow body; a third step, consisting in treating the hollow body with plasma in order to reduce the concentration of hydrogen peroxide residues. Also disclosed is a plant for manufacturing containers in which the process is carried out in particular by way of a unit for the plasma treatment of the preforms.

A method and apparatus for sterilizing a medical instrument, such as a dental instrument. The method includes placing the medical instrument in a chamber, providing a sterilizing agent including recombined ionized humidified air, controlling the temperature of the medical instrument and/or the chamber such that the temperature of the medical instrument is below the temperature of chamber, and at least partially condensing the sterilizing agent onto the instruments.

The invention describes a method and a walk through apparatus to treat surfaces with hydroxyl ions to reduce the viability and/or kill pathogens.

Aspects of the disclosure relate to storage assemblies including at least part of a delivery device and an implant. The storage assemblies are configured to trap sterilizing ethylene oxide gas using its high water solubility and converting the escaped ethylene oxide to less detrimental ethylene glycol and ethylene chlorohydrin to protect the implant from damage. In one example, the storage assembly includes an inner container housing the implant and sterilizing fluid and an outer container positioned over the inner container, wherein the outer container is at least partially filled with aqueous water. The implant may be a prosthetic heart valve. Aspects of the disclosure also relate to methods of sterilizing the storage assemblies of the disclosure.
