Definitions

  • the invention relates to a microwave or radio-frequency device.
  • the solution of the multimode resonant cavity is not satisfactory from the industrial point of view because it applies to small volumes, for example of the order of one liter of product.
  • small volumes for example of the order of one liter of product.
  • it is often necessary to have a total power greater than a few kW, but the design of a homogeneous electromagnetic distribution with a single source then poses a serious problem.
  • the invention relates more particularly to a microwave or radio frequency device comprising an applicator intended to receive a product to be treated and several generators supplying the applicator via propagation guides.
  • a device of this type is known from the European patent application published July 12, 2000 under the number EP 1018856.
  • Two generators feed the applicator via a magic tee.
  • the homogeneity of the electric field in the applicator is obtained by a combination of the electric field distributions produced by the two generators operating in a decoupled manner with respect to each other, ie without debiting the one in the other.
  • the decoupling is obtained by the magic tee and the symmetry of the object to be irradiated with respect to a median plane.
  • the power supply of this type of device is limited to two generators.
  • the object of the invention is to modify a microwave or radio-frequency device of the type recalled above to increase the total irradiation power of the device while maintaining a homogeneous electromagnetic field distribution in the applicator.
  • the subject of the invention is a microwave or radio-frequency device comprising an applicator intended to receive a product to be treated and several generators supplying the applicator via propagation guides, characterized in that that three propagation guides propagating the microwaves or the radio-frequencies generated respectively by three generators are respectively mounted on three plates forming a tri-rectangular trihedron and are arranged symmetrically with respect to the ternary axis of symmetry of the trihedron for that the generators feed the applicator by being decoupled from each other.
  • the decoupling of generators is explained by the theory of electrical images.
  • the electromagnetic field produced by a source, situated above a perfectly conducting indefinite plane, can be calculated by adding to the electromagnetic field produced by the source, that produced by the symmetrical image of this one with respect to the metallic plane.
  • the three propagation guides of the device according to the invention are arranged symmetrically on the three faces of the tri-rectangular trihedron identified OX, OY, OZ to open into the applicator so as to propagate an electric field respectively parallel to the axis OX, parallel to the OY axis and parallel to the OZ axis.
  • the images of the propagation guide disposed in the XOY plane, with respect to the YOZ and ZOX planes, are all located in the same XOY plane with electric fields parallel to OX.
  • these images emit electric field distributions whose polarization is parallel to OX, ie perpendicular to the polarization of the electric field of the distributions emitted by the two other generators. As long as the applicator is empty or occupied by a homogeneous object, the three generators are thus decoupled.
  • the decoupling of the three generators allows the applicator to irradiate the object to be treated homogeneously, with three separate electromagnetic field distributions that add up.
  • the total power supplied by the generators is thus three times that provided by each of them. It is possible for example to irradiate an object with a total power of 2.7 kW using three generators of 900 W each. From an economic point of view, if each generator costs 50 euros, we get 2.7 kW for 150 euros.
  • the use of three low-power generators dispenses with the use of Circulators that are needed when using high power generators.
  • each magnetron can be supplied by each of the three phases of the three-phase sector, so that the power supply of an applicator remains balanced.
  • Figure 1 schematically shows a microwave device according to a first embodiment of the invention.
