Embodiment Construction

[0052] about the attached figure 1 and 2 , shows a sterilization device comprising two flat U-shaped discharge vessels 1, 2 formed of a non-conductive material such as glass. The tubes 1, 2 extend side by side along their length and are separated by a substantially uniform gap.

[0053] The interior 31 of the tubes 1, 2 is filled with an inert gas such as neon or another ionizable gas under partial vacuum. The tubes 1,2 are hermetically sealed at both ends 3,32 and 4,33. On one end of each tube 1 , 2 a metal contact 5 is included which is covered by an insulator 6 to provide means for connecting a high voltage power supply 18 via a wire 28 which is connected to the metal contact 5 through the insulator 6 .

[0054] The discharge tubes 1 , 2 are mounted against a reflector 7 having a front surface that outlines the receiving tubes 1 , 2 . A portion of reflector 7 extends between each tube. The reflector 7 is made of a ferromagnetic material such as ferrite or ferrite powde...

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 oxidising potential and kill all micro organisms in contact with the ozone and reactive species resulting in the disinfection of the product as well as the interior of the sealed package.

Description

technical field [0001] The present invention relates to methods, apparatus for sterilizing or sanitizing packaged articles, such as packaged food and beverage products. Background technique [0002] The shelf life of food is substantially shortened due to the presence of microorganisms in the food, which can cause food spoilage. Not only does shelf life affect the economic viability of food producers, but it has a direct impact on public health, since the presence of certain microorganisms in food may be dangerous if ingested. These problems can be exacerbated if the food is not kept sufficiently frozen, since microorganisms in the food can multiply rapidly. [0003] In order to overcome the above-mentioned problems, it has been proposed to sterilize food by pasteurization. However, the disadvantage of pasteurization is that it is a lengthy process and can only be used on certain types of food. Furthermore, the pasteurization process affects the taste of the food and is e...
