Device for treating a product with microwaves

A device for treating a product with microwaves, wherein the device comprises a treatment chamber, in which the product can be transported along a transport path in a transport direction through the treatment chamber, and a microwave radiation device arranged in the treatment chamber, by means of which microwaves coupled into the microwave radiation device can be radiated, which act on the product, wherein the microwave radiation device comprises at least one coaxial conductor which protrudes into the treatment chamber, or is arranged therein, with an electrically-conductive internal conductor and an electrically-conductive external conductor,

• wherein the external conductor, arranged coaxially, surrounds the internal conductor in a spaced manner and comprises at least one opening, which enables an emission of microwaves from the coaxial conductor through the opening on to the product,
• wherein the microwave radiation device comprises multiple coaxial conductors, which are arranged spaced from one another in the transport direction, with in each case at least one opening in the respective external conductor,
• wherein in a coaxial conductor arranged successively in the transport direction, the at least one opening is arranged offset, transversally to the transport direction, to the at least one opening of a preceding coaxial conductor, and
• wherein individual ones of the coaxial conductors can be adapted to an overall desired or predetermined microwave output in terms of the microwave output radiated by each one of the coaxial conductors.
