Patent ID: 8278610

Claim:
A resonance chamber, especially for an apparatus for pasteurization of liquid products, comprising: a liquid product flow conduit made of a material permeable to microwaves; a metal enclosure to that surrounds the flow conduit; microwave generators, each with an antenna, the microwave generators fastened to the chamber enclosure walls so that the respective antennae (i) are directed inside the chamber and (ii) are arranged in cooperating pairs, wherein orientations of the respective pairs of antennae ( 3 , 4 ) of the microwave generators alternate inside the chamber so that (1) each pair of antennae ( 3 , 4 ) is situated within a same section of the product flow conduit, and (2) respective symmetry axes of each pair of antennae ( 3 , 4 ) do not coincide and are shifted relative to each other, and one antenna ( 3 ) of each pair of antennae is placed on one side of the product flow conduit ( 2 ), while the other antenna ( 4 ) of each pair of antennae is placed on the other side of that product flow conduit ( 2 ).
