    An arrangement for heating with the aid of microwave energy, comprising a microwave generator constructed to supply a waveguide, the waveguide having provided in one side surface thereof a dielectric plate through which microwave energy propagates. In accordance with the invention the arrangement includes at least two microwave generators (1, 2), each of which is arranged to supply a feed waveguide (3, 4). The feed waveguide (3, 4) is a power divider which is arranged to distri­bute the power input substantially equally to at least two applicators (7, 8; 9, 10) which extend at an angle to the feed waveguide, where each of the at least four applicators (7, 8; 9, 10) is provided on one side sur­face thereof with a dielectric plate (11, 12, 14) of the aforesaid kind. The applicators are positioned in relation to one another so that all dielectric plates (11, 12, 14) lie in one and the same plane.

    The invention relates to devices for heating with microwave energy, in particular with regard to devices for heating continuously passing articles, such as food products, transported on a conveyor of considerable width.
    The purpose of the invention is to uniformly heat samples of a large area while maintaining compactness.
    FIG. 1. shows a device for microwave heating, a perspective view; in fig. 2 is the same, view from the side of the workpiece; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2; in fig. 5 - applicators in a dielectric case from the side of the processed product; figure 6 -. A diagram illustrating the distribution of energy at the output of the device. The device for microwave heating contains the first 1 and second 2 microwave generators, each of which is connected to the input of the first and second power dividers, respectively, which are waveguide sections 3 and 4, which have holes 5 and 6 for connecting generators 1 and 2 The power dividers distribute the supplied power equally between two applicators 7 and 8, 9 and 10, passing at an angle to waveguide sections 3 and 4. Thus, each power divider feeds two applicators 7 and B, 9 and 0. Each of four applicators 7, 8, 9 and GO supplied dielectric plates 11, 12, 13, and 14, respectively, on one side of it, all dielectric plates 11, 12, 13, and 14 are on the same plane. Along the axis of the waveguide sections 3 and 4, two elements 15 and 16, 17 are connected: 17 and 18, which are the first and second outputs of the power divider, respectively.
    To adjust the distribution between the two applicators, a metal pin 19 can be installed in the waveguide sections 3 and 4 in the middle between the coupling elements 17 and 18. The pin 19 can be fixed by means of a screw connection 20. In addition, a metal pin 21 can be mounted in the waveguide section tenor and communication elements to reduce or prevent reflection back to the generator,

    The interplay between the elements of the SNPP is a power divider over L / 2, where D is the wavelength. To ensure high power generation, the applicators are provided with a metal adjustment plate 22 located approximately opposite the dielectric plate.
    The device for microwave heating works as follows.
    The first I and second 2 microwave generators generate microwave power using a magnetron. In doing so, the magnetron must operate at a frequency slightly different from the corresponding operating frequencies of the other magnetrons, thereby avoiding the connection between adjacent dielectric plates. Microwave power divider through power dividers enters the appropriate applicators, through the dielectric plates which enters the product, thereby ensuring their heating.
    To heat the product from two sides:
    i
    It is advisable to place two devices at a certain distance from each other with active surfaces facing towards each other, with the products being moved in the gap formed between the active surfaces. If necessary, the active surface can be curved. In such cases, the applicators and waveguide sections will also be curved.
    A microwave heating device allows uniform power distribution over a wide width or area of treatment, with power distribution being insensitive to load fluctuations.
