SED-260SDW-A tunnel-type microwave drying machine. 30 m tunnel with 26 microwave chambers, 1200 mm wide stainless mesh-belt conveyor; total power ≤260 kVA; 2450 MHz Toshiba water-cooled magnetrons with oil-cooled microwa
مبدأ العمل
Multi-chamber multi-source microwave architecture: 2450 MHz Toshiba magnetrons feed power top-down through cross-polarized waveguides into 26 rectangular cavities; product moves through on a stainless mesh belt while microwave choke entrances(60 mm aperture,~1800 inductive comb fins + absorber material) prevent leakage. Oil-immersed microwave transformer(1800 V) with variable-frequency drive ensures adjustable output power(50 W–1250 W per unit). PLC(FX-series) + touch-screen HMI with Raytek(Germany) infrared thermometers distributed across chambers for real-time temperature monitoring and auto power adjustment. 7-inch LCD camera allows visual monitoring inside the tunnel. Temperature control range: 0–400 °C.
