Calculation and design of a continuous-flow microwave oil-melting device with an ellipsoid resonator
The purpose of the study is to develop a continuous-flow radio-tight microwave oil melter with air-cooled magnetrons and a metal-dielectric resonator for heat treatment of viscous raw materials in the process of its dosed movement in the resonator volume using a dielectric bladed rotor to achieve uniform heating at reduced energy costs. Three-dimensional modeling of the structural design of a microwave oil melter with an ellipsoidal resonator was carried out in the Compass-3D V18 program. Visualization of the distribution of the electromagnetic field in an ellipsoidal resonator, calculation of its own quality factor and electric field strength was carried out in the CST Microwave Studio program. The main characteristics of the developed model of microwave oil melter are: intrinsic quality factor of the resonator - within 8 - 9 thousand; electric field strength in the resonator due to the interference of three waves - 1.2 - 1.5 kV/cm; with a generator power of 1.2 - 1.5 W/g, the microwave can operate with a capacity of 30 kg/h and energy costs in the range of 0.15 - 0.16 kWh/kg.
