Development and justification of the parameters of the microwave installation for heat treatment of rejected chicken eggs

Abstract

Russia ranks sixth in the world in egg production, with only 13% being processed. In addition, egg waste from incubation cabinets is also accumulated, which can be processed into protein feed using vacuum boilers. In this regard, the development of technology and technical means using the energy of the electromagnetic field of ultra-high frequency for heat treatment of rejected eggs in a continuous mode for farms is relevant. The aim of the research is to develop and substantiate the parameters of the microwave installation for heat treatment of rejected chicken eggs as a protein feed additive. Tasks are being solved: to develop a spatial model of a microwave installation of a continuous operation mode; calculate the construction parameters of the installation. The microwave installation developed contains a vertically mounted truncated non-ferromagnetic bicone. Along its inner side surface, a dielectric tube is laid in the form of a biconical spiral. Parallel to the vertical axis of the bicone, a non-ferromagnetic plate is installed, dividing its volume into two chambers: a resonator and a pause chamber. The plate is made in the form of an axial section of a truncated bicone, along the perimeter of which there are openings for transcendental waveguides worn on the dielectric tube from the pause chamber side. On the side surface of the bicone mounted magnetrons. The structural design of the installation ensures the continuity of the heat treatment process without transporting mechanisms. The calculated self-quality of the resonator is 5000. With an installation capacity of 18 kg/h, the specific energy consumption for heat treatment of eggs is 200 W.h/kg.
