Abstract A microwave-frequency oven intended primarily for heating food-stuffs in which a microwave-frequency electromagnetic oscillator is connected through the slot-type exciter to the chamber formed as a body of revolution, with the chamber being provided with a loading-unloading opening; a rotor is installed inside said chamber in coaxial relationship therewith, with the shaft of the rotor carrying radially and equidistantly spaced blades provided with seals to prevent dissipation of microwave-frequency energy; said blades correspond to the shape of the housing of the chamber through which they move, and divide the chamber into isolated compartments, with shelves of dielectric material for placing products thereupon being positioned between the lower and upper edges of the blades perpendicular to the axis of the shaft, said shelves forming the disk whose outer shape corresponds to the shape of the housing of the chamber, whereas the chamber is provided with holes coinciding with the slots in the slot-type exciter, and while the slot-type exciter itself is so positioned in relation to the chamber that in the course of operation it communicates with some of the compartments forming the working portion of the chamber.
A microwave frequency turntable-type continuous oven having a loading section and shielded cooking sections, comprising: a chamber shaped as a body of revolution with holes, and a loading-unloading opening; a rotor installed inside said chamber in coaxial relationship therewith; a shaft of said rotor carrying radially and equidistantly spaced blades corresponding to the shape of the housing of said chamber through which they move, and dividing said chamber into compartments; shelves of dielectric material positioned between the upper and lower edges of said blades perpendicular to the axis of said shaft, which together form a disk whose outer shape corresponds to the shape of the housing of said chamber; seals positioned on said blades to prevent dissipation of the microwave-frequency energy; a slot-type electromagnetic exciter so positioned in relation to said chamber that in the course of operation it communicates with some of said isolated compartments forming the working portion of said chamber, while said holes in the chamber coincide with the slots in said slot-type exciter.

Claim 3
Dependent Claim
49 words
The microwave-frequency oven as set forth in claim 1, wherein for uniform heating of the product each of the shelves is provided with a carrier so installed that when passing through the working portion of the chamber the carrier is rotated in a horizontal plane around its own axis.
Claim 4
Dependent Claim
68 words
The microwave-frequency ovens as set forth in claim 1, wherein in order to protect the microwave-frequency oscillator against overload, when there is no product in the working portion of the chamber, the rotor shaft is of a hollow design, and made of current-conducting material, having holes closed by stoppers of dielectric material, and which is filled with a material, such as running water, capable of absorbing electromagnetic energy.
