Development and justification of parameters of a microwave convective hop dryer

To solve the problem of low energy efficiency and absence small-sized hop dryers, a microwave convective continuous-flow dryer has been developed with reasonable parameters that allow preserving consumer properties hops. The scientific innovative idea implementing technology drying hops in working chamber dryer, made form tiered rotors located between stationary nonferromagnetic bases, forming coaxial resonators which traveling wave from generators is excited, considered. are perforated non-ferromagnetic outer inner shells, where ceramic partitions rigidly installed annular space, allowing to concentrate radiation raw materials reduce losses. Having calculated dimensions resonator, having created its three-dimensional model Compass 20 program, we imported it into CST Microwave Studio program substantiate electrodynamic parameters. A capacity 5 kW spiral decelerating systems will ensure uniform compliance electromagnetic safety, 100 kg/h when rotor without sources two comply process duty cycle 0.5.
