| Popis: | Introduction. The existing methods of cooking eggs in water and with steam have a high energy intensity. Currently, the problem of continuity of the technological process is still not solved. That is why, in order to reduce energy consumption, reduce water consumption and intensify the process of heat treatment of eggs, we consider it relevant to use the energy of the electromagnetic field of super high frequency (SHFEMF) in a special temperature regime without using water.Methodology. Three-dimensional modeling of the installation was carried out in the Compass 18.0 program, the justification of the heat treatment modes was carried out by analytical methods, to identify the optimal parameters (energy consumption and temperature regime) of the proposed installation, second-degree least squares polynomials were used, in particular, a rotatable second-order planning matrix, statistical analysis of the matrix was carried out in a software package for statistical analysis Statistica 12, confirmation of analytical data with empirical data was carried out in the CST Microwave Studio program for three-dimensional modeling of electromagnetic field propagation processes in the Eigenmode calculation module, where patterns of electric and magnetic field intensity distribution in a spherical resonator were studied.Results. The structural design of the conveyortype radio wave installation allows for heat treatment of eggs when moving in dielectric cups through slotted spherial resonators. The borehole of the process is less than 0.5 due to the location of the cups in the resonators and between them in relation 4:9. The value of the resonator's own Q-factor reaches 8800. The visualization in the program shows a uniform distribution of the electric field in the resonator, with a voltage of 1.5–3 kV/cm, which ensures high sterility of the product. From the regression models compiled on the basis of the matrix of rotatable planning of the second-order experiment, it follows that the effective duration of exposure to EMF is 154 s, the specific energy costs are equal to 143 Wh/kg. The speed of rotation of the conveyor gear motor is 0.4 rpm. |
