  • Patent number: 10178874
    Abstract: An apparatus for sterilising a packaged product (16) such as food or drink comprises a pair of gas filled electrodes (1, 2) connected to a power supply (18) for generating a high voltage pulses between the electrodes (1, 2) sufficient to ionise the gas therein and to create a high electromagnetic field therebetween. A reflector (7) is provided for directing the generated field towards the package (16), such that the electromagnetic field penetrates through the wall of the package (16) and forms cold plasma from the trapped air inside the package (16). This cold plasma comprises ozone and other reactive oxygen based species which have a high oxidizing potential and kill all microorganisms in contact with the ozone and reactive species resulting in the disinfection of the product as well as the interior of the sealed package.

  • Patent number: 9597422
    Abstract: An apparatus for generating ozone inside packaged articles comprises an electrode assembly in which coplanar electrodes are supported along a contact surface. The electrodes are solid state conductive electrodes. These electrodes may be interdigitated and/or arranged with uniform spacing therebetween along a portion of their length. Where the electrodes are straight they may be parallel, but other shapes can also be evenly spaced. In some examples the electrodes are partially insulated and partially exposed. In some examples the electrodes are embedded/potted in an insulator to exclude air spaces from around the electrodes.
