Zusammenfassung:	FIELD: SHF drying f woods. ^ SUBSTANCE: packages of woods are put into cassette with longitudinal recesses in side walls through which recesses the packages are treated with HF energy pulse flux. Inside the flux the packs of woods are formed on top branch of transporter. The pack is introduced into cassette and the pack is treated from its middle to its ends with SHF pulses during three steps. During first step the packs are warmed till 35-65°, during the second step - till 60-90° and during third step - till 75-105°. Circulation of vapor-air mixture is carried out which mixtures washes warmed packs about and after it the mixture is sucked away. Device for SHF-drying of woods has frame onto which cassette with woods is mounted. Longitudinal recesses of the cassette join magnetrons. Cassette is made in form of side, lower and top walls limiting its volume. Cassette's ends are closed with shutters. Any magnetron is provided with fan for supplying air into chamber for washing woods' packs about. ^ EFFECT: improved quality of drying. ^ 6 cl, 3 dwg
