RU95111012A - Wood drying method - Google Patents

Abstract

FIELD: woodworking and furniture production industry. SUBSTANCE: application of method excludes wood heating operation procedure, heating of water in capillaries and heating of surrounding structures which in all increases power efficiency. According to method, wooden articles are piled in drying chamber, electric electrodes are installed at ends of articles to ensure electric contact between electrodes and wooden articles. Then electric field is created with direct component being directed along wood fibers, and drying agent is delivered for evaporation of moisture from wood surface. Additionally electric field of 200-260 V/m is applied, and beside that, also applied is pulsing electric field. EFFECT: high efficiency. 2 cl, 1 dwg

Claims (1)

The invention relates to techniques for drying wood and can be used in woodworking and furniture industries. The technical result achieved is an increase in the energy efficiency of the wood drying process due to the exclusion from the technology of the operation of heating the wood and, accordingly, the losses of heating the dry matter of wood, the heating of water in the capillaries and the losses of heating of the surrounding structures. According to the method, wood products are stacked in the drying chamber, electrodes are installed at the ends of the wood products to ensure electrical contact between them and the wood products, an electric field with a constant component directed along the wood fibers is applied, and a drying agent is supplied to evaporate moisture from the wood surface. In addition, an electric field of 200-260 V / m and a pulsed electric field are applied.
