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.
