Annals of Warsaw University of Life Sciences – SGGW Forestry and Wood Technology No 71, 2010: 42-46 (Ann. WULS-SGGW, For and Wood Technol. 71, 2010) Two special plants for drying of wood by superhigh frequency of electromagnetic energy A.M. BOMBIN 1 , P.S. MORDVINOV 2 1 Voronezh state Academy of Forestry Engineering, Voronezh, Russia, 2 Post-graduate student of Russian State Commercial and Economic University, Voronezh, Russia Abstract: Two special plants for drying of wood by superhigh frequency of electromagnetic energy (SHF EME) submitted in the article. First plant drying boards 3 metre length for furniture. Second plant drying of logs and beams 6 metre length for production of wooden houses. Each of this plants consume minimum of electric energy for drying of wood with needed characteristics. Boards for furniture must have moisture 6%. Logs and beams must have moisture 15%. During the process of drying boards moisture going out like steam from sides of boards. During the process of drying of logs and beams moisture going out like water and steam from end surface of logs and beams. Control panel fulfilled of manycannel programmable intellectual relay type Zelio Logic. Keywords: superhigh frequency of electromagnetic energy, drying of logs, wooden house-building, drying boards for furniture �� (�� ) ��, �� , �� . �� , �� «�� – ��». �� , �� . �� . � �� . �� 6 ��, �� 30 �� 3 �, �� . �� 6-8%. �� 26 �� 6 �, �� . �� 15-17%. � �� . �� . �� 1 � 2. �� 1 – �� (��-3�) �� 1. �� , �� 3000�300�50 2. �� , �� 26 3. �� , � � 80-105 4. �� , �� 2450 42
