The present invention relates to a device as well as a system and a method for treating an object, in particular one or more free-form objects, with plasma. The object to be treated can in particular be a raw food such as an egg, fruit or vegetable, or packaging as well, or respectively a cap, etc. Treating the object with plasma preferably serves the object of decontaminating and sterilizing the surface of the object.
The device for treating an object with plasma comprises a jacket apparatus (10) which forms, or can form, a substantially gas-tight holding chamber (15) in which an object (1) to be treated can be accommodated. The device comprises a first electrode (20) and a second electrode (21), wherein the two electrodes (20, 21) are arranged with reference to the jacket apparatus (10) such that a plasma (2) can be generated in the holding chamber (15) of the jacket apparatus (10). A wall (13) of the jacket apparatus (10) forming the holding chamber (15) of the jacket apparatus (10) has a modulus of elas-ticity of Ew<10 kN/mm2, at least in sections. The device comprises a housing (30), by means of which a housing interior (33) is or can be formed, wherein the jacket apparatus (10) is arranged within the interior of the housing (33).
