PLANT FOR DRYING WOOD IN MICROWAVE FIELD

摘要

FIELD: machine building.SUBSTANCE: invention relates to devices for microwave drying of materials and can be applied to wood processing and other industries. For implementation of device, stack of wood is put into closed metal cavity as resonator of wood drying chamber; dimensions of resonator is selected much larger than wavelength λ of supply microwave generator, so that possibility of excitation of different spatial structure oscillations plurality is provided in unloaded state within cavity. Three-arm waveguide Y-circulator allows isolation of generator at reflected reactive power and provision of feed power recovery in absorbing load.EFFECT: technical result is increased efficiency of microwave drying chamber by reducing energy losses caused by mismatch between generator and load, higher process efficiency.1 cl, 2 dwg
