Abstract The present invention relates to thermal electric equipment, and more particularly to microwave continuous ovens intended primarily for heating and cooking food-stuffs. The microwave oven according to the invention, comprises a microwave electromagnetic oscillator connected to the inner space of a housing accommodating a rotor whose shaft carries two disks which define therebetween a space divided by radial partitions rigidly connected to the disks and the shaft, which all together form sections to accommodate dielectric supports with the product being treated, with said housing being of such cross-sectional shape that in the course of rotor rotation a number of radial partitions are in contact with the inner surface of the housing to form locking compartments, with a loading-unloading opening being arranged in that part of the housing, while the remaining radial partitions are at a distance from the inner surface of the housing, which form together with the latter, a working chamber inside which the product is treated.
A turntable type microwave continuous oven with a loading section and a shielded cooking section, comprising: a housing; a microwave electromagnetic oscillator connected to the inner space of said housing for generating electromagnetic oscillation thereinside; a rotor made from current-conducting material positioned inside said housing and in coaxial relationship therewith, the shaft of the rotor carrying two disks installed in a plane perpendicular to that of the shaft rotation; the space confined within said disks being divided by radial partitions rigidly connected to said disks and shaft, which together form sections; dielectric shelves accommodated in said sections for carrying the product being treated about said shaft; said housing being of such cross-sectional shape that in the course of rotation of said rotor a number of said radial partitions which form locking compartments are in contact, through their outer edge, with the inner surface of said housing, while the remaining radial partitions are at a distance from the inner surface of the housing so as to form therewith a working chamber communicating with said microwave electromagnetic oscillator; a loading-unloading opening being arranged between said locking compartments in said housing.
