WOOD-DRYING PLANT Russian patent published in 2002 - IPC

FIELD: devices for microwave drying of materials, applicable in wood-working and other branches of industry. SUBSTANCE: the drying plant has a metal chamber with door 2 provided with limit switch 3, magnetrons staggered on the side walls of the chamber. The axes of the magnetron radiation antennas are mutually perpendicular and positioned at an angle of 45 deg to the vertical. The plant has an air-circulation system comprising pan 8, air conduit 10, air heater 11 and fan 12. On the side walls of pan 8 and in the bottom of air conduit 10 provision is made for holes, whose diameter does not exceed 0.1 of the magnetron radiation wavelength, they are arranged from one another at a distance equal to 1/4 of the magnetron radiation wave-length. Vertical partitions of radioparent moistureproof material are positioned between the chamber walls and pan 8 for the material to be dried. EFFECT: enhanced capacity due to reduced drying time and enhanced quality of dried material. 1 cl, 2 dwg
