FIELD: wood-working industry.
SUBSTANCE: device comprises chamber, waveguides connected with the microwave magnetrons mounted on the sides of the chamber in staggered order, cooling system, device for charging and discharging wood material, vacuum system, water drain system, and system for smooth switching on the magnetrons. The chamber is cylindrical, and the magnetrons are arranged on the cylinder in tree rows for permitting repeatable changing of the polarization rotation of the output signal. The polarizations of adjacent waveguides are orthogonal. The waveguide of rectangular shape has top member whose cross-section is the rectangular trapezium. The outlets of the waveguides are plugged with a dielectric transparent for radio waves for protecting the magnetrons against vacuum.
EFFECT: enhanced quality of drying.
