DEVELOPMENT OF WORKING CHAMBERS OF MICROWAVE INSTALLATIONS FOR THERMAL TREATMENT OF INEDIBLE MEAT PRODUCTION WASTE
The working chambers of the microwave installations for heat treatment and disinfection of inedible meat production waste with regard to the given below technical requirements are developed. Continuity is achieved by perforation of the resonators and the dissector. High intensity up to 5 kV/cm, at which bacterial microflora is destroyed, is achieved by the special design of the toroidal cavity and the superposition of two electric fields of different wave lengths. High basic Q-factor of the resonator is achieved due to its spherical or toroidal implementation. Electromagnetic compatibility of installation is achieved by use of a shielding housing of non-ferromagnetic material and the below-cutoff waveguides instead of intake and discharge nozzles. Installation versatility for a wide range of raw materials is achieved by regulating the diameter of the perforating holes and the pump performance of viscous product. The uniformity of electric field distribution and raw materials in volumetric resonator is achieved due to its spherical performance and the use of dissector. The dissector simultaneously provides the raw materials distribution through the volume of the resonator and the protection of adjoining magnetrons from reflected flux of radiation. The increase in productivity is achieved by means of use of several low-power generators, air-cooled and without the need for protection from reflected power. They provide a uniform heating of raw materials due to design techniques in the development of cavities filled with small volumes of raw materials. The dismantling of the installation units is aimed at ensuring sanitary treatment after the thermal treatment of raw materials. Compliance with the duty cycle of the technological process is less than 0.5 with multiple cyclic effects of the electromagnetic super-high- frequency field is aimed at the stabilization of temperature and pressure by volume of raw materials.
