It is convenient to install microwave heating equipment for high performance on several sections of grooved waveguides that are included quasi-periodically, however, it is important to increase the input power and distribute it more evenly for increasing productivity and uniformity of heating. The product enters through the open wall on the conveyor belt, and the section is powered by two magnetron generators on two ports of the ZHV. We consider the possibility of feeding the section from above with two additional sources, which gives a more uniform distribution of the field. Using two side power sources and two sources connected to the top of the chute allows you to get significantly more uniform heating and triple the power input into the section. The paper analyzes the distribution of the square of the electric field on the axis of the chamber. The proposed design makes it possible to increase the productivity of the installation, improve the uniformity of the field and heating, and make the installation more compact. The proposed version is used into production in the company «Etna-Plus LLC».
