Date Mar. 25, 1999Food is rendered sterile by UV irradiation, preferably with UV at 265+ / -15 nm. A sterilization unit may include UV sources (90, 100, 110, 120) and a heat source, which may be a broad band UV source, a source of IR or microwave radiation. A combined microwave / UV unit can be used to defrost frozen food and simultaneously sterilize it or maintain sterility. Heating prior to UV irradiation can enhance the sterilization, as can rapid cooling after irradiation. Irradiation can also be enhanced by displacing the food during irradiation e.g. by supporting it on a rotatable support (135) and / or by displacing it relative to the support surface.

Plant Air Purification Enclosure Apparatus and Method
InactiveUS20120311926A1Reduce the amount requiredEasy to deployMechanical apparatusRoot feedersThermal energyEngineering
A plant air purifying enclosure, or “PAPE,” contained within an unconditioned space, either within or outside a building, containing therein a plant air purifier, which is used to purify air using plants and microbes growing therein. The PAPE enclosure itself receives poor indoor quality air from within structure where the PAPE is located or from a structure close by along with thermal energy which keeps the plant air purifier enclosure at a suitable temperature for the plants and air cleaning microbes within the air purifier. Poor air enters the enclosure, is purified by the plants and microbes, and returns in purified form back to the habitable space from which it was taken. This lowers the amount of outside air needed for ventilation purposes and so lessens a building's overall energy consumption while providing efficiently for naturally purified air. Fundamentally, the object of this invention is to specify devices, systems and methods to house / enclose plant purifiers in such a way that they can readily be deployed on a wide scale.

Food products, such as precooked meats, sausages, and the like are microbially decontaminated in their cooking packages to remove surface microorganism contamination from the packages. The cooking packages are removed and the food products optionally subjected to further processing, such as slicing, and then packaged in aseptic packaging. The microbial decontamination step, further processing and packaging are carried out in a clean room which is maintained to a high level of sterilization or disinfection to minimize or eliminate contamination of the food products with pathogenic microorganisms such as Listeria Monocytogenes. The food products thus leave the packaging plant with a much higher assurance of food safety than is found in a conventional packaging plant.
